1. Introduction

Türkiye has become one of the world’s leading destinations for healthcare and medical tourism, attracting hundreds of thousands of international patients each year. Modern hospitals, internationally trained physicians, competitive treatment costs and comparatively short waiting times have positioned the country as a preferred destination for cosmetic surgery, dental treatment, hair transplantation, ophthalmology, orthopaedics, bariatric surgery, reproductive medicine and numerous other specialised medical services.

While the overwhelming majority of medical treatments performed in Türkiye are successful, adverse outcomes occasionally occur. In some cases, these outcomes are unavoidable medical complications arising despite appropriate treatment. In others, they may result from failures to comply with accepted professional standards. Distinguishing between these two situations lies at the heart of medical malpractice law.

Medical malpractice is one of the most technically complex areas of Turkish law because it combines principles of civil liability, contract law, criminal law, administrative law, constitutional rights and professional medical ethics. Determining whether a healthcare provider is legally responsible rarely depends upon the medical outcome alone. Instead, Turkish courts examine whether the physician, dentist, hospital or other healthcare provider acted with the level of knowledge, skill and care reasonably expected from a competent professional under the particular circumstances of the case.

As healthcare services become increasingly international, medical malpractice disputes frequently involve foreign patients who return to their home countries before complications become apparent. These cross-border cases raise additional legal questions concerning jurisdiction, evidence, expert medical reports, limitation periods and representation before Turkish courts. Consequently, understanding the legal framework governing medical malpractice has become increasingly important not only for Turkish patients and healthcare providers but also for international patients, foreign lawyers, insurers and medical tourism stakeholders.

This guide provides a comprehensive overview of medical malpractice law in Türkiye. It examines the legal framework governing healthcare professionals, explains how Turkish courts determine liability, analyses the distinction between medical negligence and recognised medical complications, discusses available compensation and litigation procedures, and reviews the leading decisions of the Turkish Court of Cassation. Particular attention is given to issues affecting foreign patients who have received medical treatment in Türkiye.

This article focuses specifically on medical malpractice litigation. Readers seeking broader information regarding international health tourism, healthcare investments, intermediary organisations and regulatory aspects of cross-border medical treatment may also wish to read our separate guide on International Medical and Health Tourism Law in Türkiye.

2. Legal Framework Governing Medical Malpractice in Türkiye

Unlike some jurisdictions that regulate medical negligence through a single statute, Turkish medical malpractice law is derived from multiple legal sources. Civil liability, contractual obligations, criminal responsibility, administrative law and professional ethics operate together to regulate the conduct of healthcare professionals. Consequently, every malpractice case requires a careful assessment of several legal instruments alongside the extensive jurisprudence of the Turkish Court of Cassation.

2.1. Constitutional Principles

Medical malpractice law ultimately derives from the constitutional protection afforded to life, bodily integrity and human dignity. The Constitution of the Republic of Türkiye guarantees every individual’s right to protect and develop his or her material and spiritual existence while imposing a duty upon the State to organise and supervise healthcare services. These constitutional principles influence the interpretation of healthcare legislation and have increasingly guided judicial review of medical negligence cases.

2.2. Turkish Code of Obligations

The Turkish Code of Obligations constitutes the principal source of civil liability in medical malpractice litigation. The legal relationship between a patient and a physician is generally contractual in nature. Depending upon the circumstances, this relationship may be characterised as a mandate agreement, a healthcare service contract or, particularly in cosmetic and dental procedures, a contract for work where a specific professional result is expected.

Article 112 of the Turkish Code of Obligations provides that a party who fails properly to perform a contractual obligation is liable for the resulting damage unless he or she proves that the failure occurred without fault. This provision plays a central role in private healthcare disputes and has been repeatedly applied by the Turkish Court of Cassation, particularly in cases concerning dental treatment and cosmetic procedures (Turkish Court of Cassation, 6th Civil Chamber, 19 November 2025, E.2024/2425, K.2025/3957). Where no contractual relationship exists, liability may arise under the general provisions governing tortious acts.

2.3. Turkish Penal Code

Medical malpractice may also result in criminal liability where negligent conduct causes bodily injury or death. However, criminal responsibility arises only if all statutory elements of the relevant offence are satisfied. The Turkish Penal Code criminalises negligent bodily injury and negligent homicide. Nevertheless, criminal liability is exceptional. Turkish courts consistently emphasise that physicians are not criminally responsible simply because treatment fails or because an unavoidable medical complication occurs.

2.4. Patient Rights Regulation

The Patient Rights Regulation represents one of the most important legal instruments governing healthcare services in Türkiye. It recognises a wide range of patient rights, including:

• the right to receive healthcare services fairly and respectfully;
• the right to information regarding diagnosis and treatment;
• the right to informed consent;
• the right to refuse treatment in certain circumstances;
• the right to privacy and confidentiality;
• the right to access medical records.

Breaches of these rights frequently constitute important evidence in subsequent medical malpractice proceedings.

2.5. Medical Ethics and International Standards

Medical malpractice law in Türkiye is also influenced by professional ethical rules and international conventions. The Medical Deontology Regulation and the Turkish Medical Association’s Professional Ethical Rules require physicians to practise according to current scientific knowledge, exercise appropriate professional care, maintain confidentiality and continually improve their professional competence. Türkiye is also a party to the Convention on Human Rights and Biomedicine (Oviedo Convention), which establishes internationally recognised principles concerning informed consent, protection of human dignity, organ transplantation and biomedical interventions. Turkish courts increasingly interpret domestic healthcare legislation consistently with these international standards.

2.6. The Role of the Turkish Court of Cassation

Although legislation establishes the general legal framework, the detailed principles governing medical malpractice have largely been developed through judicial decisions. Over the past two decades, the Turkish Court of Cassation has clarified numerous fundamental issues, including:

• the legal definition of medical malpractice;
• the distinction between malpractice and recognised medical complications;
• the concept of permitted medical risk;
• the applicable standard of professional care;
• the burden of proof;
• the evidential value of expert medical reports;
• contractual liability in private healthcare;
• hospital liability; and
• the assessment of pecuniary and non-pecuniary damages.

These decisions have produced a coherent body of jurisprudence that aligns Turkish medical malpractice law with internationally recognised principles of professional negligence while reflecting the specific characteristics of the Turkish healthcare system.

3. Establishing Medical Malpractice Under Turkish Law

Medical malpractice cannot be established merely because a medical procedure fails to achieve the desired outcome. Modern medicine is inherently uncertain, and even the most experienced physicians cannot guarantee successful treatment in every case. Every medical intervention involves recognised risks, biological variability and the possibility of complications despite appropriate professional care. For this reason, Turkish law distinguishes between an unsuccessful medical outcome and legally actionable medical negligence. The decisive question is not whether harm occurred but whether the healthcare provider departed from the professional standard reasonably expected from a competent practitioner under similar circumstances.

3.1. Definition of Medical Malpractice

Neither the Turkish Code of Obligations nor the Turkish Penal Code contains a comprehensive statutory definition of medical malpractice. Instead, the concept has been developed through professional ethical rules and judicial interpretation. The Turkish Medical Association defines malpractice as harm suffered by a patient due to a physician’s lack of knowledge, lack of experience or negligence during professional practice. Turkish courts have consistently adopted this definition while interpreting it in light of contemporary medical science and internationally accepted professional standards. In its landmark decision of 27 March 2024, the Criminal General Assembly of the Turkish Court of Cassation explained that physicians are required to exercise the degree of professional knowledge, skill and diligence expected from a competent medical practitioner. However, they are not guarantors of successful treatment outcomes. A physician incurs legal liability only where injury results from a departure from accepted medical standards rather than from an unavoidable medical risk or recognised complication (Turkish Court of Cassation, Criminal General Assembly, 27 March 2024, E.2020/12-370, K.2024/158). This principle forms the cornerstone of modern Turkish medical malpractice law.

3.2. The Standard of Professional Care

The concept of the standard of care lies at the centre of every medical malpractice claim. Turkish courts assess whether the physician acted as a reasonably competent practitioner in the same specialty would have acted under similar circumstances. This assessment is objective and depends upon the scientific knowledge, clinical guidelines, diagnostic methods and treatment standards existing at the time of the medical intervention rather than those developed with hindsight. Accordingly, the law does not require perfection. Physicians remain free to exercise professional judgment where different medically acceptable treatment options exist. Liability arises only when the physician’s conduct falls below the standard reasonably expected from a competent healthcare professional. The standard of care extends beyond the medical procedure itself. It includes the physician’s responsibilities before, during and after treatment, including proper diagnosis, treatment planning, obtaining informed consent, maintaining accurate medical records, monitoring the patient’s condition, consulting specialists where necessary and responding appropriately to post-operative complications.

3.3. Informed Consent

Obtaining a patient’s informed consent is one of the fundamental legal and ethical obligations of every healthcare professional in Türkiye. Respect for patient autonomy is firmly embedded in Turkish healthcare legislation, professional ethical rules and international human rights instruments. A failure to obtain valid informed consent may itself constitute a breach of the physician’s legal duties, even where the medical intervention has been performed competently. The legal basis of informed consent is found primarily in the Patient Rights Regulation, the Medical Deontology Regulation and the Convention on Human Rights and Biomedicine (Oviedo Convention), to which Türkiye is a contracting state. Together, these instruments recognise that every competent individual has the right to decide freely whether to undergo a proposed medical intervention after receiving sufficient information to make an informed decision.

Valid informed consent requires considerably more than obtaining the patient’s signature on a standard form. Turkish courts consistently emphasise that a signed consent form, by itself, does not prove that the patient has been adequately informed. Rather, the physician must demonstrate that the patient received understandable and sufficient information regarding:

• the diagnosis;
• the purpose of the proposed treatment;
• the nature of the medical procedure;
• the expected benefits;
• foreseeable risks and possible complications;
• reasonable alternative treatment options;
• the likely consequences of refusing treatment.

The information provided should be appropriate to the patient’s level of understanding and should enable a reasonable person to make an informed decision regarding the proposed intervention. The scope of disclosure becomes particularly important in elective procedures, including cosmetic surgery, aesthetic dentistry and hair transplantation. Unlike emergency or life-saving interventions, these procedures are generally undertaken to improve appearance or quality of life rather than to treat an immediately life-threatening condition. Consequently, Turkish courts expect physicians to provide particularly comprehensive information regarding realistic expectations, possible aesthetic limitations, revision surgery, scarring, asymmetry and other foreseeable risks before treatment is undertaken.

There are limited exceptions to the requirement for informed consent. Emergency treatment necessary to preserve life or prevent serious and irreversible harm may be performed without prior consent where obtaining consent is impossible. Such exceptions, however, are interpreted narrowly and do not relieve healthcare providers of their obligation to document the circumstances justifying emergency intervention.

In medical malpractice litigation, disputes concerning informed consent frequently focus not upon whether a consent form was signed, but whether meaningful communication actually took place. Comprehensive medical records documenting the information provided, the questions asked by the patient and the discussion of foreseeable risks often become decisive evidence during litigation.

3.4. Medical Malpractice versus Medical Complication

Perhaps the most important principle governing Turkish medical malpractice law is the distinction between medical negligence and a recognised medical complication. Medicine is not an exact science. Every diagnostic procedure, surgical intervention and medical treatment carries inherent risks that cannot be completely eliminated, regardless of the physician’s competence. Complications may occur despite meticulous preparation, appropriate clinical decision-making and strict compliance with accepted professional standards. Accordingly, Turkish law does not impose liability simply because an adverse medical outcome occurs. The Turkish Court of Cassation has consistently held that physicians are responsible for exercising reasonable professional care, not for guaranteeing successful treatment. The decisive legal question is therefore whether the healthcare provider complied with the applicable standard of care throughout the patient’s diagnosis, treatment and follow-up. The Criminal General Assembly has provided the clearest judicial explanation of this principle. The Court recognised that medicine necessarily involves permitted medical risks and that recognised complications may occur despite appropriate treatment. However, once a complication develops, the physician remains under a continuing duty to identify, monitor and manage that complication according to accepted medical standards. Failure to recognise or appropriately treat a developing complication may itself constitute malpractice (Turkish Court of Cassation, Criminal General Assembly, 27 March 2024, E.2020/12-370, K.2024/158). The distinction is well illustrated by the Court’s case law.

In one case concerning an eighteen-month-old child suffering from acute gastroenteritis, the Court accepted that infant gastroenteritis may progress rapidly and can be fatal despite appropriate treatment. Nevertheless, the treating physician failed to admit the child for observation and did not initiate treatment directed at dehydration despite clear clinical indications. The Court concluded that these omissions constituted medical malpractice because the deficiencies in treatment were causally connected to the child’s death (Turkish Court of Cassation, 12th Criminal Chamber, 2 April 2015, E.2014/9296, K.2015/5790).

By contrast, in a case involving kidney transplantation, malignant disease was transmitted from the donor organ to the recipient, ultimately resulting in the deaths of both individuals. Expert reports established that all recognised donor screening procedures, multidisciplinary consultations and post-operative management complied with accepted medical standards. The Court therefore characterised the event as an unavoidable medical complication rather than malpractice and rejected the compensation claim (Turkish Court of Cassation, 3rd Civil Chamber, 8 April 2025, E.2024/2168, K.2025/1976). These decisions demonstrate that Turkish courts evaluate the quality of the medical decision-making process rather than simply the final outcome.

3.5. The Essential Elements of a Medical Malpractice Claim

Although the legal basis of a claim may vary depending upon the circumstances, Turkish medical malpractice litigation generally requires four essential elements.

Duty of Care: A physician, dentist, hospital or other healthcare provider assumes a legal duty of care once a professional relationship with the patient has been established. This duty extends beyond diagnosis and treatment to include appropriate examination, treatment planning, informed consent, proper documentation, follow-up care and referral where necessary.

Breach of the Standard of Care: The claimant must establish that the healthcare provider failed to act in accordance with accepted medical standards. Examples include:

• delayed diagnosis;
• failure to perform appropriate diagnostic investigations;
• surgical errors;
• medication errors;
• failure to monitor the patient’s condition adequately;
• inadequate post-operative care;
• failure to obtain valid informed consent.

Importantly, courts evaluate professional conduct according to the knowledge reasonably available at the time of treatment rather than through retrospective criticism based upon later developments.

Causation: Negligence alone does not create liability. The claimant must also establish a causal relationship between the breach of duty and the injury suffered. This requirement frequently represents the most challenging aspect of medical malpractice litigation because many patients suffer from complex underlying illnesses. Expert medical evidence is therefore essential in determining whether earlier diagnosis or different treatment would probably have altered the patient’s clinical outcome. The Turkish Court of Cassation has repeatedly emphasised that diagnostic uncertainty alone does not constitute malpractice. In a recent decision concerning an incorrect diagnosis of cancer, the Court held that although the diagnosis later proved inaccurate, the treating physicians had acted consistently with accepted pathological findings and no additional harmful treatment had resulted. Consequently, no actionable malpractice was established (Turkish Court of Cassation, 3rd Civil Chamber, 8 April 2025, E.2024/2458, K.2025/1975).

Damage: Finally, the claimant must demonstrate actual damage. Compensable losses may include physical injury, psychological harm, additional medical expenses, future treatment costs, loss of earnings, permanent disability and non-pecuniary damage. Without legally recognisable damage, a breach of professional standards alone will generally not justify an award of compensation.

Burden of Proof and Expert Medical Evidence: Medical malpractice litigation is highly evidence-driven. Success rarely depends upon allegations alone; it requires careful analysis of medical records, expert opinions and the applicable professional standards. As a general rule, the claimant bears the burden of establishing the facts supporting the allegation of malpractice. However, in contractual disputes arising from private healthcare services, Article 112 of the Turkish Code of Obligations assumes particular significance. Once defective contractual performance has been established, the healthcare provider must demonstrate that the failure occurred without fault. Expert medical evidence occupies a central role throughout Turkish malpractice litigation. Because judges are not medical specialists, scientific issues concerning diagnosis, treatment, causation and professional standards are ordinarily resolved through court-appointed experts. Depending upon the nature of the dispute, expert opinions may be obtained from:

• the Council of Forensic Medicine (Adli Tıp Kurumu);
• university medical faculties;
• specialist academic panels; or
• independent court-appointed experts.

The Turkish Court of Cassation consistently requires lower courts to examine expert reports critically and to resolve material inconsistencies before reaching a final judgment. Conflicting expert opinions may require supplementary reports or the appointment of additional expert panels. Medical records are equally important. Clinical notes, operative reports, pathology reports, radiological images, laboratory results, nursing records, informed consent documentation and discharge summaries frequently provide the most persuasive evidence when determining whether treatment complied with accepted professional standards.

4. Liability and Compensation

Medical malpractice may give rise to civil, criminal, administrative and professional disciplinary liability under Turkish law. These forms of liability pursue different legal objectives and operate independently. Accordingly, a physician may be acquitted in criminal proceedings but nevertheless remain liable to compensate the patient in civil litigation, or vice versa.

4.1. Civil Liability

Civil liability is the principal legal remedy available to patients who suffer harm as a result of negligent medical treatment. Its primary purpose is not to punish healthcare professionals but to compensate injured patients for losses directly attributable to medical negligence. The legal basis of civil liability depends upon the relationship between the patient and the healthcare provider. In private healthcare, the relationship is generally contractual. Patients entering into treatment agreements with private hospitals, private clinics or physicians may pursue claims based on the Turkish Code of Obligations where contractual duties have not been properly performed. Conversely, where treatment is provided outside a contractual framework, liability may arise under the general rules governing tortious acts. Regardless of the legal basis, Turkish courts examine the same essential questions:

• Did the healthcare provider breach the applicable professional standard?
• Did that breach cause the patient’s injury?
• What losses resulted from the injury?

4.2. Public and Private Hospital Liability

The distinction between public and private healthcare providers is particularly important under Turkish law. Private hospitals generally bear contractual responsibility towards their patients. Their liability extends beyond the acts of individual physicians and includes failures relating to:

• hospital organisation;
• patient safety;
• staffing;
• nursing services;
• infection control;
• maintenance of medical equipment;
• preservation of medical records;
• emergency response systems;
• coordination between medical departments.

Accordingly, liability may arise not only from negligent medical treatment but also from organisational deficiencies within the hospital itself. Where both the treating physician and the hospital contribute to the patient’s injury, Turkish courts may hold both parties legally responsible. Different principles apply to public hospitals operated by the Ministry of Health, state universities and other public authorities. In these cases, liability generally arises from the administrative responsibility of the public administration rather than from an ordinary contractual relationship. Claims concerning medical treatment provided by public hospitals often require proceedings before the administrative courts under the rules governing the liability of public authorities. Because jurisdiction, procedural requirements and limitation periods differ significantly from those applicable to private healthcare providers, obtaining specialised legal advice at an early stage is particularly important.

4.3. Criminal Liability

Medical malpractice does not automatically constitute a criminal offence. Criminal liability arises only where negligent conduct satisfies the statutory elements of offences such as negligent bodily injury or negligent homicide under the Turkish Penal Code. The Turkish Court of Cassation consistently emphasises that physicians are not criminally responsible merely because treatment proves unsuccessful or because recognised medical complications occur. Criminal responsibility requires proof that the physician departed from accepted professional standards and that this departure caused the prohibited result. Accordingly, criminal proceedings focus upon personal culpability rather than compensation.

4.4. Professional and Disciplinary Responsibility

Healthcare professionals are also subject to professional disciplinary rules. Physicians may become subject to disciplinary proceedings before the Turkish Medical Association, while dentists may be investigated by the relevant Chambers of Dentists and the Turkish Dental Association. Disciplinary sanctions may include warnings, fines or other professional measures. Although disciplinary findings do not automatically establish civil liability, Turkish courts frequently regard them as persuasive evidence when supported by expert medical opinions. This principle was clearly demonstrated in a significant dental malpractice decision, where the Turkish Court of Cassation relied upon both the disciplinary findings of the Chamber of Dentists and the expert opinion of Istanbul University’s Faculty of Dentistry when concluding that the dentist had failed to comply with accepted professional standards (Turkish Court of Cassation, 6th Civil Chamber, 19 November 2025, E.2024/2425, K.2025/3957).

4.5. Compensation

A successful claimant may recover both pecuniary and non-pecuniary damages. Pecuniary damages may include:

• medical and hospital expenses;
• corrective treatment costs;
• rehabilitation expenses;
• future medical care;
• nursing and caregiver expenses;
• travel and accommodation costs associated with corrective treatment;
• loss of earnings;
• diminished earning capacity;
• funeral expenses where applicable;
• loss of financial support suffered by dependants.

Non-pecuniary damages (moral damages) compensate for physical pain, emotional suffering, psychological distress, permanent disability, disfigurement and reduced quality of life. When determining compensation, Turkish courts consider numerous factors, including the seriousness of the injury, the permanence of disability, the patient’s age, the degree of fault, future medical needs and the overall impact upon the patient’s personal and professional life. Unlike some common law jurisdictions, Turkish law does not recognise punitive or exemplary damages. The purpose of compensation is restorative rather than punitive.

5. Common Medical Malpractice Claims in Türkiye

Medical malpractice may arise in virtually every medical specialty. Nevertheless, judicial practice demonstrates that certain categories of disputes appear far more frequently than others. The following areas represent the most common types of malpractice claims before Turkish courts.

5.1. Misdiagnosis and Delayed Diagnosis

Diagnostic errors remain one of the leading causes of malpractice litigation. Liability may arise where physicians fail to recognise significant clinical findings, delay necessary diagnostic investigations, misinterpret laboratory or radiological examinations or fail to refer patients to appropriate specialists within a reasonable time. However, Turkish courts distinguish negligent diagnosis from legitimate diagnostic uncertainty. In a recent case concerning an allegedly incorrect cancer diagnosis, pathology findings initially suggested malignancy, resulting in surgical treatment. Subsequent examinations demonstrated that the patient did not suffer from cancer. The Turkish Court of Cassation nevertheless concluded that the diagnosis had been medically justifiable based upon the available pathological findings and that no additional harmful treatment had resulted. Consequently, the Court held that an incorrect diagnosis alone does not automatically constitute malpractice (Turkish Court of Cassation, 3rd Civil Chamber, 8 April 2025, E.2024/2458, K.2025/1975). This decision confirms that liability depends upon whether the physician acted reasonably in light of the information available at the relevant time rather than upon the eventual correctness of the diagnosis.

5.2. Surgical Errors

Surgical negligence extends beyond technical mistakes made during an operation. Claims frequently concern:

• inadequate pre-operative assessment;
• failure to establish an appropriate surgical indication;
• operating on the wrong anatomical site;
• damage to neighbouring organs through negligent technique;
• retained foreign objects;
• inadequate post-operative monitoring;
• delayed recognition of complications;
• failure to undertake timely corrective intervention.

The Turkish Court of Cassation consistently evaluates the entire continuum of surgical care—from diagnosis and planning to postoperative management—rather than focusing exclusively on the operation itself.

5.3. Cosmetic Surgery

Türkiye is internationally recognised as one of the world’s leading destinations for cosmetic and reconstructive surgery. Procedures such as rhinoplasty, breast augmentation, breast reduction, liposuction, abdominoplasty, facelift surgery and body contouring attract substantial numbers of international patients each year. Because these procedures are elective rather than medically necessary, the legal expectations placed upon cosmetic surgeons are particularly demanding. Patients seeking aesthetic improvement often have high expectations regarding the anticipated outcome. Physicians therefore bear a correspondingly enhanced duty to provide comprehensive information concerning realistic expectations, foreseeable complications, possible asymmetry, scarring, revision surgery and the limitations of aesthetic procedures. Dissatisfaction with a cosmetic result does not automatically establish malpractice. Medicine is not capable of guaranteeing aesthetic perfection, and individual healing characteristics differ considerably from one patient to another. However, liability may arise where poor aesthetic results are attributable to inadequate planning, negligent surgical technique, failure to obtain informed consent, deficient postoperative care or departures from accepted scientific standards. Given Türkiye’s prominent position in international cosmetic surgery, these disputes frequently involve foreign patients. Accordingly, comprehensive documentation, pre-operative photographs, informed consent records and postoperative follow-up assume particular evidential significance in litigation.

5.4. Hair Transplantation

Hair transplantation has become one of Türkiye’s most recognised medical tourism sectors. Thousands of patients from the United Kingdom, continental Europe, the Middle East and North America travel to Türkiye each year for Follicular Unit Extraction (FUE), Direct Hair Implantation (DHI) and other advanced hair restoration procedures. Although these procedures generally achieve high patient satisfaction, the rapid expansion of the sector has also resulted in an increase in disputes concerning treatment quality and patient safety. Medical malpractice claims arising from hair transplantation commonly involve allegations such as:

• inadequate pre-operative assessment;
• inappropriate patient selection;
• unrealistic treatment planning;
• excessive harvesting from the donor area (overharvesting);
• implantation of an insufficient number of grafts;
• poor hairline design;
• infection resulting from inadequate hygiene;
• treatment performed by unqualified personnel;
• inadequate post-operative care or follow-up.

Turkish law evaluates hair transplantation according to the same legal principles applicable to all medical interventions. The mere fact that the cosmetic outcome falls short of the patient’s expectations does not establish negligence. Courts instead examine whether the clinic and treating physician complied with accepted medical standards throughout patient assessment, surgical planning, the procedure itself and post-operative management.

Particular attention is paid to the physician’s duty to explain realistic expectations before treatment. Patients should be informed that final results depend upon numerous biological factors, including the quality of the donor area, hair characteristics, age, hormonal influences and individual healing responses. Failure to provide adequate pre-operative information may constitute a breach of the duty to obtain informed consent even where the technical aspects of the procedure have been properly performed. As with cosmetic surgery, comprehensive photographic documentation before and after treatment, detailed operative records and informed consent documentation frequently become critical evidence in subsequent malpractice litigation.

5.5. Dental Malpractice

Dental malpractice has become one of the fastest-growing categories of healthcare litigation in Türkiye, reflecting the country’s position as a leading destination for international dental tourism. Every year, thousands of foreign patients travel to Türkiye for implant surgery, full-mouth rehabilitation, zirconia crowns, porcelain veneers, smile design procedures and other restorative or cosmetic dental treatments. While most treatments are completed successfully, malpractice claims frequently arise from:

• defective implant planning;
• implant failure attributable to negligent treatment;
• incorrectly designed prosthetic restorations;
• occlusal disorders;
• nerve injuries;
• infection;
• unnecessary extraction of healthy teeth;
• inadequate diagnosis;
• aesthetic failures;
• insufficient informed consent.

Unlike many therapeutic medical interventions, complex prosthetic and cosmetic dental procedures frequently combine functional and aesthetic objectives. Turkish courts therefore expect dentists not only to restore oral function but also to perform treatment in accordance with accepted scientific and professional standards capable of achieving a satisfactory functional and aesthetic result. This principle was clearly confirmed by the Turkish Court of Cassation in an important decision concerning implant-supported prosthetic treatment. The patient alleged that the prosthetic restorations were functionally inadequate and aesthetically unacceptable. Reports prepared by the Faculty of Dentistry of Istanbul University concluded that the restorations failed to satisfy accepted professional standards, while disciplinary proceedings before the Chamber of Dentists resulted in sanctions against the treating dentist.

The Court held that the dentist had failed properly to perform the contractual obligation under Article 112 of the Turkish Code of Obligations and emphasised that university expert reports together with disciplinary findings constituted persuasive evidence of professional negligence (Turkish Court of Cassation, 6th Civil Chamber, 19 November 2025, E.2024/2425, K.2025/3957). This judgment is particularly significant because it demonstrates that Turkish courts carefully examine both the functional and aesthetic quality of dental treatment and recognise that contractual liability may arise where professional standards have not been observed.

5.6. Organ Transplantation

Organ transplantation represents one of the most technically sophisticated areas of modern medicine. Procedures involving living or deceased donors require rigorous compliance with legal requirements, multidisciplinary assessment and internationally recognised medical protocols. Healthcare providers undertaking transplantation procedures are expected to perform comprehensive donor screening, recipient evaluation, infectious disease testing, malignancy screening and post-operative monitoring in accordance with current scientific standards. A leading decision of the Turkish Court of Cassation illustrates the distinction between recognised medical risk and professional negligence. Following a kidney transplant, malignant disease originating from the donor organ was transmitted to the recipient, ultimately resulting in the deaths of both the donor and the recipient. Despite the tragic outcome, expert reports established that all recognised donor screening procedures, multidisciplinary consultations and follow-up measures had been properly performed. The Court concluded that the transmission of malignancy represented an unavoidable medical complication rather than medical malpractice because the treating physicians had complied with accepted professional standards throughout the transplantation process (Turkish Court of Cassation, 3rd Civil Chamber, 8 April 2025, E.2024/2168, K.2025/1976). The decision demonstrates an important principle of Turkish medical negligence law: liability depends upon the quality of professional conduct rather than the severity of the medical outcome.

5.7. A Practical Observation

Although medical malpractice claims arise across virtually every medical specialty, Turkish judicial practice demonstrates a common pattern. Successful claims rarely depend upon a single isolated mistake. Instead, liability typically results from a combination of deficiencies, including inadequate assessment, incomplete documentation, failures in communication, delayed diagnosis, insufficient monitoring, improper management of recognised complications and departures from accepted scientific standards. For this reason, Turkish courts evaluate the patient’s entire course of treatment—from the initial consultation and diagnostic process to post-treatment follow-up—rather than focusing exclusively on one medical decision or the ultimate clinical outcome.

6. Medical Malpractice Claims by Foreign Patients

Over the past two decades, Türkiye has established itself as one of the world’s leading destinations for medical tourism. Patients travel from the United Kingdom, Germany, France, the Netherlands, Ireland, Scandinavia, the Gulf region, North America and many other countries to receive cosmetic surgery, dental treatment, hair transplantation, bariatric surgery, ophthalmic procedures and other specialised healthcare services.

The rapid growth of international medical tourism has inevitably been accompanied by an increase in cross-border medical malpractice disputes. Many patients only become aware of potential negligence after returning home, raising complex legal questions concerning jurisdiction, evidence, expert medical opinions and representation before Turkish courts. Turkish law provides foreign patients with the same legal protection afforded to Turkish nationals. Nationality does not affect the patient’s right to seek compensation where medical malpractice can be established.

6.1. Can Foreign Patients Sue in Türkiye?

Yes. Foreign nationals who receive medical treatment in Türkiye may bring medical malpractice claims before Turkish courts under the same legal principles applicable to Turkish citizens. Depending upon the circumstances, proceedings may be brought against:

• physicians;
• dentists;
• surgeons;
• private hospitals;
• medical clinics;
• healthcare companies;
• diagnostic laboratories;
• other healthcare providers involved in the patient’s treatment.

The claimant’s nationality, residence or place of domicile does not prevent access to Turkish courts.

6.2. Do Patients Need to Remain in Türkiye?

In most cases, no. Foreign patients are generally not required to remain in Türkiye throughout the litigation. Instead, they may appoint a Turkish lawyer by granting a power of attorney before the Turkish Embassy or Consulate in their country of residence. Once the power of attorney has been properly executed, the lawyer may conduct court proceedings, communicate with the court, obtain expert reports, submit evidence and represent the client’s interests throughout the litigation. This significantly reduces travel costs and enables foreign patients to pursue claims without repeatedly travelling to Türkiye.

6.3. What Evidence Should Be Preserved?

Medical malpractice cases are primarily decided on documentary and expert evidence. Patients should therefore preserve every document connected with their treatment, including:

• hospital admission records;
• consultation notes;
• laboratory reports;
• pathology reports;
• radiological images;
• operative reports;
• prescriptions;
• invoices and payment receipts;
• informed consent forms;
• discharge summaries;
• follow-up recommendations;
• correspondence with the clinic or hospital.

Where cosmetic procedures, dental treatment or hair transplantation are involved, patients should also retain high-quality photographs taken before treatment, immediately after treatment and during the recovery process. These photographs frequently become valuable evidence when expert medical panels evaluate the quality of treatment. Travel documents, hotel reservations and communications with medical tourism facilitators may likewise become relevant where cross-border contractual relationships are disputed.

6.4. Medical Records

Turkish healthcare providers have a legal obligation to maintain medical records. These records often constitute the most important evidence in malpractice litigation because they document the patient’s medical condition, diagnostic findings, treatment decisions, operative procedures and post-operative care. Where records appear incomplete, inconsistent or inaccurate, Turkish courts may draw appropriate evidential conclusions after examining expert medical opinions and other available evidence. Accordingly, obtaining complete copies of all medical records at an early stage is strongly recommended.

6.5. Independent Medical Opinions

Many international patients obtain second opinions after returning to their home countries. Although reports prepared by foreign physicians may assist in understanding the patient’s medical condition, Turkish courts ordinarily appoint independent experts during litigation. Consequently, foreign medical opinions generally complement rather than replace court-appointed expert evidence. Nevertheless, well-reasoned reports prepared by recognised specialists may help explain the chronology of treatment, identify potential departures from accepted medical standards and assist Turkish lawyers in preparing the case.

6.6. Limitation Periods

Foreign patients should not delay obtaining legal advice. Medical malpractice claims are subject to statutory limitation periods, and the applicable time limit depends upon several factors, including:

• whether the claim is contractual or tortious;
• whether treatment was provided by a private or public hospital;
• whether criminal proceedings are also involved; and
• the specific facts of the individual case.

Determining the correct limitation period requires careful legal analysis. Delaying legal advice may jeopardise the patient’s right to pursue compensation.

6.7. Why Early Legal Assessment Matters

International medical malpractice cases frequently involve complex evidential issues. Medical records may need to be translated, expert opinions obtained, witnesses identified and technical medical questions analysed before proceedings are commenced. Early legal assessment allows potential evidential deficiencies to be identified while documentation remains readily available. It also enables patients to understand whether the unfortunate outcome they experienced is likely to be regarded under Turkish law as:

• an unavoidable medical complication;
• an accepted medical risk; or
• actionable medical malpractice.

Early legal advice therefore protects both the patient’s legal position and the quality of the evidence ultimately presented before the court.

7. Practical Guide to Bringing a Medical Malpractice Claim

Although every medical malpractice case presents unique medical and legal issues, successful claims generally follow a similar sequence. Careful preparation during the early stages often has a decisive influence on the eventual outcome of the litigation.

Step 1 – Prioritise Your Health

The first priority should always be obtaining appropriate medical care. Where further treatment is required, patients should seek prompt medical attention from another qualified healthcare provider. Protecting the patient’s health always takes precedence over legal considerations. Corrective treatment may also provide valuable medical evidence regarding the nature and extent of the original injury.

Step 2 – Collect Medical Documentation

Patients should obtain complete copies of all available medical records as soon as possible. These documents typically include:

• consultation notes;
• laboratory results;
• imaging studies;
• operative reports;
• pathology reports;
• prescriptions;
• nursing records;
• discharge summaries;
• informed consent documentation.

Incomplete medical records frequently become a significant issue in malpractice litigation. Early collection helps minimise evidential difficulties.

Step 3 – Preserve Additional Evidence

Patients should retain all documents relating to the treatment. This includes:

• invoices;
• payment receipts;
• correspondence with healthcare providers;
• appointment confirmations;
• travel documentation;
• accommodation records where relevant.

For cosmetic procedures, dental treatment and hair transplantation, dated photographs documenting the patient’s condition before and after treatment are particularly valuable.

Step 4 – Obtain a Professional Legal Assessment

Not every unsuccessful treatment constitutes medical malpractice. An experienced lawyer will evaluate whether the available evidence suggests:

• a breach of the applicable professional standard;
• a causal relationship between treatment and injury;
• sufficient medical evidence to support litigation;
• the appropriate legal basis for the claim;
• the competent court and procedural requirements.

Early assessment often prevents unnecessary litigation while identifying strong claims at an early stage.

Step 5 – Commencing Legal Proceedings

Where settlement cannot be achieved, proceedings may be commenced before the competent Turkish court. The statement of claim normally includes:

• a detailed chronology of treatment;
• the alleged breaches of professional duty;
• supporting documentary evidence;
• legal arguments;
• the compensation sought.

The defendant healthcare provider is then given an opportunity to respond before expert examination begins.

Step 6 – Court-Appointed Expert Examination

Almost every medical malpractice case in Türkiye depends upon expert medical evidence. The court may appoint experts from:

• the Council of Forensic Medicine;
• university medical faculties;
• specialist academic institutions;
• independent medical experts.

Where different expert reports conflict, supplementary reports or additional expert panels may be appointed.

Step 7 – Judgment and Appeals

After considering the documentary evidence, witness testimony and expert reports, the court delivers judgment. Depending upon the nature and value of the dispute, the decision may subsequently be reviewed by the Regional Court of Appeal and, where legally permissible, by the Turkish Court of Cassation. The extensive jurisprudence of the Court of Cassation has played a central role in establishing the modern principles governing Turkish medical malpractice law and continues to provide authoritative guidance for lower courts.

8. Selected Leading Decisions of the Turkish Court of Cassation

Although Turkish medical malpractice law is founded upon legislation, many of its most important principles have been developed through the jurisprudence of the Turkish Court of Cassation. The following decisions illustrate the current approach adopted by Turkish courts when assessing medical negligence claims.

Legal Principle	Leading Authority
Definition of medical malpractice and permitted medical risk	Turkish Court of Cassation, Criminal General Assembly, 27 March 2024, E.2020/12-370, K.2024/158
Failure to manage dehydration constitutes malpractice	Turkish Court of Cassation, 12th Criminal Chamber, 2 April 2015, E.2014/9296, K.2015/5790
Misdiagnosis does not automatically establish malpractice	Turkish Court of Cassation, 3rd Civil Chamber, 8 April 2025, E.2024/2458, K.2025/1975
Transmission of cancer through organ transplantation regarded as a recognised medical complication	Turkish Court of Cassation, 3rd Civil Chamber, 8 April 2025, E.2024/2168, K.2025/1976
Defective implant-supported dental treatment gives rise to contractual liability	Turkish Court of Cassation, 6th Civil Chamber, 19 November 2025, E.2024/2425, K.2025/3957

Taken together, these decisions demonstrate several consistent principles that now characterise Turkish medical malpractice law. First, physicians are expected to exercise reasonable professional care rather than guarantee successful treatment outcomes. Secondly, recognised medical complications do not automatically establish negligence. Thirdly, liability depends upon proving both a departure from accepted professional standards and a causal relationship between that departure and the patient’s injury. Finally, expert medical evidence remains indispensable in virtually every medical malpractice case.

9. Frequently Asked Questions

9.1. What is medical malpractice under Turkish law?

Medical malpractice refers to injury caused by a healthcare professional’s failure to comply with accepted medical standards. A poor medical outcome alone is insufficient. The claimant must establish negligence, causation and legally compensable damage.

9.2. Is every unsuccessful operation considered malpractice?

No. Turkish law clearly distinguishes recognised medical complications from professional negligence. Many adverse outcomes occur despite appropriate medical care. Courts examine whether the healthcare provider complied with accepted professional standards rather than focusing solely on the final result.

9.3. Can foreign patients sue in Türkiye?

Yes. Foreign nationals enjoy the same legal protection as Turkish citizens and may pursue compensation before Turkish courts where medical malpractice can be established.

9.4. Can I start legal proceedings after returning to my home country?

Yes. Most foreign patients appoint a Turkish lawyer through a power of attorney executed before the Turkish Embassy or Consulate in their country of residence. Personal attendance is generally unnecessary except in exceptional circumstances.

9.5. Who may be held legally responsible?

Depending upon the circumstances, liability may arise against:

• physicians;
• dentists;
• surgeons;
• private hospitals;
• healthcare companies;
• diagnostic laboratories;
• public healthcare institutions; and
• other healthcare providers involved in the patient’s treatment.

In some cases, both the individual healthcare professional and the hospital may be jointly responsible.

9.6. What compensation may be claimed?

Patients may recover compensation for:

• medical expenses;
• future treatment costs;
• rehabilitation;
• loss of earnings;
• diminished earning capacity;
• nursing expenses;
• funeral expenses where applicable; and
• non-pecuniary (moral) damages for pain, suffering and psychological harm.

Each case is assessed individually according to its particular facts.

9.7. Are punitive damages available?

No. Turkish law does not recognise punitive or exemplary damages in medical malpractice cases. Compensation aims to restore the injured patient’s losses rather than punish the healthcare provider.

9.8. How important are expert reports?

Expert medical evidence is fundamental. Because judges are not medical specialists, Turkish courts ordinarily rely upon independent experts from the Council of Forensic Medicine, university medical faculties or other specialist institutions when determining whether accepted professional standards have been breached.

9.9. How long does a medical malpractice case take?

The duration varies depending upon the complexity of the medical issues, the number of expert reports required and the availability of appellate review. Cases involving multiple expert examinations generally require longer than ordinary civil disputes.

9.10. What should I do if I suspect medical malpractice?

You should first obtain appropriate medical treatment to protect your health. Thereafter, preserve all available medical records, obtain copies of relevant documentation and seek legal advice without unnecessary delay. Early legal assessment significantly improves the ability to preserve evidence and evaluate the merits of a potential claim.
