Legal Remedies for Exorbitant Fees and Unfair Billing in Private Hospitals

What is the problem of exorbitant fees and unfair billing in private hospitals?

The problem of exorbitant fees and unfair billing in private hospitals arises when a patient is charged for services exceeding the actual cost of the healthcare provided, exceeding the limits permitted by legislation, without prior clear information being provided, without a detailed breakdown, or for services not actually received by the patient. This problem can manifest itself in emergency services, childbirth, surgery, intensive care, cancer treatment, angiography, laboratory tests, imaging, hospitalization, accompanying person fees, doctor's fee, room fee, consumables, medication costs, or under the guise of "package services.".

In disputes over private hospital fees, the first distinction is whether the hospital has a contract with the Social Security Institution (SGK) and whether the patient received services covered by SGK. In private hospitals contracted with SGK, the additional fees that can be charged to the patient are limited by SGK regulations. According to SGK information, for contracted healthcare providers, including foundation universities, excluding public administration healthcare providers, the Institution has the authority to set a ceiling on the additional fees that can be charged in addition to the healthcare service fee determined by the Institution. In practice, this limit is expressed as "up to twice the fee determined by the Institution".

Conversely, if a private hospital does not have a contract with the Social Security Institution (SGK) or if the patient receives services entirely under private patient status, the SGK's additional fee limits may not be applied directly. However, even in this case, the hospital cannot charge unlimited and arbitrary fees. The patient must be informed about the fee, an invoice must be issued, a detailed breakdown of the service must be provided, the prices of medications and medical supplies must not exceed market rates, and the hospital must act in accordance with consumer law and principles of fairness. According to the Private Hospitals Regulation, it is mandatory to issue a sales receipt or invoice for all patients treated in outpatient or inpatient settings at private hospitals; the invoice must include a document showing a detailed breakdown of the health services provided to the patient and their unit prices.

Can private hospitals freely set their own fees?

Private hospitals have the right to charge fees. However, this right is not unlimited. Especially for private hospitals contracted with the Social Security Institution (SGK), the additional fees that can be charged for healthcare services covered by SGK are limited by legislation. Even if a hospital considers the amount paid by SGK insufficient, it cannot demand a difference from the patient exceeding the legal limit on this grounds.

In private healthcare providers contracted with the Social Security Institution (SGK), the fee charged under the name of "additional fee" is the difference that the hospital requests from the patient in addition to the cost of the healthcare service covered by SGK. However, this difference cannot be requested for every procedure, and no additional fee can be charged for some healthcare services. The information published by SGK clearly states that no additional fee can be charged for services such as emergency situations, intensive care services, burn treatment, cancer treatment, healthcare services for newborns, organ-tissue-stem cell transplantation services, surgical procedures for congenital anomalies, hemodialysis treatments, and certain cardiovascular surgical procedures.

Therefore, when reviewing a private hospital bill, the following questions should be asked: What service does the fee relate to? Was this service covered by the Social Security Institution (SGK)? Does the hospital have a contract with SGK? Is the fee an additional charge? Is the procedure one of the services for which an additional fee cannot be charged? Was the patient clearly informed about the fee and any additional charges beforehand?

Can a private hospital charge a fee in the emergency room?

Emergency departments are the area where private hospital fee disputes most frequently occur. There is a widespread belief in society that "private hospital emergency services absolutely cannot charge fees"; however, the practice is more detailed. No co-payments or additional fees can be charged for emergency medical services provided under emergency conditions. The Social Security Institution (SGK) states that no co-payments or additional fees are charged to individuals for emergency medical services provided under emergency conditions by contracted or non-contracted healthcare providers.

However, not everyone who visits the emergency room will have their condition deemed an "emergency" under the regulations. Applications that are not considered emergencies after examination may be evaluated using procedure codes such as "green zone examination." Therefore, when reviewing a private hospital's emergency room bill, the patient's triage code, emergency assessment, procedures performed, and how the billing is handled by the Social Security Institution (SGK) should be examined first.

According to the Social Security Institution's (SGK) explanation regarding additional fees, the emergency situation ends when the patient is stabilized within 24 hours of arriving at the emergency department and admitted to the relevant clinic or transferred to the inpatient clinic of another healthcare provider. Additional fees cannot be charged for emergency interventional procedures performed directly after admission to the emergency department, or for all healthcare services provided in emergency observation units within 24 hours. For an additional fee to be charged, the patient must provide a written statement, signed by both parties, confirming that the emergency situation has ended and that subsequent procedures are subject to additional fees.

Therefore, patients paying for treatment in the emergency room should definitely request the following documents: emergency room records, triage form, discharge summary, list of procedures performed, invoice, SGK (Social Security Institution) provision information, notification form stating that the emergency situation has ended, and, if applicable, the patient's signed consent form for the fee.

Fee Request for Healthcare Services Where Additional Fees Cannot Be Charged

In some healthcare services, private hospitals cannot charge patients additional fees. This prohibition aims to protect areas where patients are most economically vulnerable and in the most urgent medical situations. According to the latest information from the Social Security Institution (SGK), additional fees cannot be charged for healthcare services provided due to emergencies, intensive care services, burn treatment, radiotherapy, chemotherapy and radioisotope treatments in cancer treatment, newborn services, organ, tissue and stem cell transplantation services, surgical procedures for congenital anomalies, hemodialysis treatments, and some cardiovascular surgical procedures.

For example, if a patient in the intensive care unit of a private hospital is charged a fee under the name of "intensive care supplement," it should be examined which service this fee relates to. If an additional fee is charged for chemotherapy services to a cancer patient, this request should be evaluated separately in terms of SGK (Social Security Institution) regulations. If a supplementary fee is requested from the family for neonatal intensive care services, it should be investigated on what basis the hospital justified this cost.

Here, hospitals sometimes add items such as "private room," "companion," "package service," "doctor's fee," "consumables," and "additional services" to services that are not eligible for additional charges. Whether these items represent services actually received, requested, and compliant with regulations can be determined from a detailed invoice. Therefore, a general invoice stating "health service fee" or "hospital service fee" is often insufficient.

Right to Request an Invoice and Detailed Statement

In disputes regarding private hospital fees, the most important evidence is the invoice and a detailed breakdown of services provided. The Private Hospitals Regulation mandates the issuance of a sales receipt or invoice for all patients treated in private hospitals, whether on an outpatient or inpatient basis. Furthermore, the invoice must include a document detailing the healthcare services provided and their unit prices. The same regulation also stipulates that the costs of medications and medical supplies used in private hospitals cannot exceed market prices.

This regulation gives the patient a strong legal right. The patient is not obligated to settle for a single-line invoice stating "total 80,000 TL for healthcare services." They can request a detailed document showing how much was charged for each examination, test, medication, consumable, room, surgery, doctor's service, and procedure.

Private hospitals are also obligated to provide certain documents free of charge upon request by the patient. The regulation stipulates that documents such as a list showing the types and quantities of medications and supplies used in the private hospital and paid for by the patient, results of tests, analyses, and imaging procedures paid for by the patient, prescriptions for medications and supplies purchased externally, and discharge summaries related to treatment will be provided to the patient free of charge.

Therefore, the patient or their relative must request the following documents in writing before applying: invoice, detailed service breakdown, unit price list, discharge summary, SGK (Social Security Institution) provision information, list of medications and consumables used, medical supply costs, payment receipts, fee information form, consent forms, and package service agreement, if applicable.

Excessive Fees at Private Hospitals Contracted with SGK (Social Security Institution)

The most frequent dispute in private hospitals contracted with SGK (Social Security Institution) concerns exceeding the legal limit for additional fees. Patients are often unaware of how much SGK has paid to the hospital. Therefore, to determine if the fee charged is legal, treatment information and SGK transaction records can be reviewed via e-Government. Additionally, the SGK's additional fee calculation screen provides an approximate estimate based on hospital type, additional fee rate, treatment type, specialty, and transaction information.

Private healthcare institutions contracted with the Social Security Institution (SGK) are required, under certain conditions, to provide patients with a document detailing the services provided and any additional fees charged. According to the SGK's information, private healthcare providers at the secondary and tertiary levels, as well as foundation universities contracted with the Institution, are obligated to provide patients with a document detailing the services and additional fees no later than the discharge date, if the total cost of inpatient treatments covered by the Institution under the same application number exceeds 100 TL.

Once these documents are obtained, the claim of overcharging becomes more concrete. For example, if it is found that the hospital charged significantly more than the legal limit for a procedure covered by the Social Security Institution (SGK), the patient can first apply to the hospital in writing to request a refund. If the hospital does not pay, the patient can then pursue legal action through the SGK Provincial Directorate, the Consumer Arbitration Board, or the Consumer Court.

Are Exorbitant Fees Always Illegal?

Not every fee that appears exorbitant is automatically illegal. If a private hospital does not have a contract with the Social Security Institution (SGK) or if the patient received services entirely as a private patient, there is greater freedom of contract in determining the fee. However, legal objections are still possible if the patient was not informed beforehand, payment was obtained under duress in an emergency, the price was changed afterwards, a fee was charged without the service being provided, a detailed breakdown was not given, or the costs of medications and materials exceed market rates.

The Patient Rights Regulation covers all public and private institutions providing healthcare services and recognizes the patient's right to request information on how to access healthcare services. Furthermore, the patient can request information about their health condition and planned medical procedures; they can review and obtain copies of their medical files and records directly or through a representative.

Information regarding fees is also part of patient rights. The patient should know the approximate cost of the procedure, the portion covered by the Social Security Institution (SGK), any additional fees charged, the cost of a private room or companion, items not included in the package, and any additional charges that may arise later. Clear information about the cost should be provided upfront, especially for planned surgeries, births, cosmetic procedures, dental treatments, physical therapy, IVF, check-ups, or long-term hospital stays.

What are unfair invoice items?

Unfair or disputed items on private hospital bills can manifest in various ways. One example is the inclusion of charges for services not provided to the patient. For instance, fees may be charged for tests not performed, supplies not used, private room services not received, or medication not administered.

The second unfair charge is the multiple charging of the same service. For example, services that should be included in the package surgery cost may be listed separately. Anesthesia, operating room fees, standard consumables, or hospitalization fees included in the surgery package may be billed again.

The third problem is charging patients extra for services covered by the Social Security Institution (SGK) or for which additional fees are prohibited. Fees charged for services such as intensive care, emergency care, cancer treatment, or neonatal care should be examined with particular care. The SGK's list of services for which additional fees cannot be charged is a key control tool in this regard.

The fourth problem is the overvaluation of drug and medical supply costs. The Private Hospitals Regulation explicitly stipulates that the costs of drugs and medical supplies used in private hospitals cannot exceed market prices. Therefore, in invoices for high-priced stents, prostheses, implants, consumables, drugs, or specialized medical supplies, market prices and whether they were actually used should be investigated.

Written Application and Refund Request to the Private Hospital

If you suspect an exorbitant fee or unfair billing, the first step is to submit a written application to the private hospital. The application should clearly state the patient's name, treatment date, protocol number, invoice number, amount paid, the items disputed, and the refund requested. Instead of simply stating "the bill is too high," you should specify which item is illegal and why.

The application may include the following requests: provision of a detailed invoice breakdown, explanation of unit prices, notification of the amount covered by the Social Security Institution (SGK), indication of the basis for any additional charges collected from the patient, refund of charges for services that are not eligible for additional fees, correction of drug and material prices exceeding market rates, and return of any unjustly collected amount with legal interest.

This application should be made via KEP (Registered Electronic Mail), notary public, registered mail with return receipt, or through the hospital's official application unit, if possible. WhatsApp or verbal communication alone may not be sufficient. A written application is crucial for subsequent processes with the Social Security Institution (SGK), the Provincial Health Directorate, the Consumer Arbitration Board, or the courts.

Application to the Provincial Directorate of Social Security Institution (SGK)

Patients who receive services under the Social Security Institution (SGK) and believe they have overpaid for emergency services or additional fees can apply to the SGK Provincial Directorate. The SGK states that if a fee is charged for emergency healthcare services, the individual, whether a general health insurance holder or a dependent, should apply to the Social Security Provincial Directorate in the province where the healthcare provider is located.

For SGK (Social Security Institution) applications, the following documents must be submitted: invoice, payment receipt, discharge summary, detailed service record, emergency room records, e-Government treatment information, the hospital's SGK contract status, and payment documents signed by the patient. SGK can evaluate whether the hospital has charged additional fees contrary to regulations and may take action against the private hospital if necessary.

However, applying to the Social Security Institution (SGK) may not always directly result in a refund to the patient. Therefore, the consumer arbitration board or consumer court can also be used to recover the unjustly collected amount.

Complaint from the Provincial Health Directorate and the Ministry of Health

If a private hospital does not provide detailed billing, does not share patient records, pressures patients to pay in emergency situations, charges for services that should not be subject to additional fees, overcharges for medical supplies, or violates patient rights, complaints can be filed with the Provincial Health Directorate and the Ministry of Health.

The application to the Provincial Health Directorate is particularly important in terms of the administrative supervision of the private hospital. Since the Private Hospitals Regulation imposes clear obligations on private hospitals regarding invoices and patient documents, violations of these obligations can be subject to administrative supervision.

This application does not replace a request for a refund; however, it may initiate administrative oversight of the hospital. Therefore, in practice, both consumer law avenues for a refund and an application to the Provincial Health Directorate for administrative oversight can be considered together.

Consumer Arbitration Board Application

In most cases, fee disputes between private hospitals and patients are considered consumer disputes. The patient is the consumer who receives healthcare services for a fee, while the private hospital is the service provider. Therefore, claims for unfair billing, overcharging, defective service, or refunds can be brought before the Consumer Arbitration Board or the Consumer Court.

For consumer disputes with a value below 186,000 TL in 2026, applications can be made to the Provincial or District Consumer Arbitration Boards. The Ministry of Trade's 2026 information states that from January 1, 2026, applications can be made to consumer arbitration boards for disputes below 186,000 TL.

According to the Ministry of Trade's information on consumer arbitration boards, for 2026, applications to the arbitration board are mandatory for disputes below 186,000 TL; for disputes of 186,000 TL and above, applications to the consumer arbitration board are not possible, and in these cases, mediation followed by proceedings in the consumer court becomes the prerequisite for litigation. Applications can be made in person, by mail, or via TÜBİS through e-Government.

The following documents must be attached to the Consumer Arbitration Board application: invoice, payment receipt, detailed service record, discharge summary, SGK (Social Security Institution) treatment information, written refund request to the hospital, hospital's response, emergency room records, additional fee documents, and price information/consent forms, if applicable.

Consumer Court and Mediation

If the amount of the dispute is 186,000 TL or more for the year 2026, an application cannot be made to the consumer arbitration board. In this case, mediation, which is a prerequisite for litigation, must be attempted first, and if an agreement cannot be reached, a lawsuit must be filed in the consumer court. The Ministry of Trade states that for disputes of 186,000 TL and above, the path of mandatory mediation followed by a lawsuit in the consumer court should be pursued in accordance with Article 73/A of Law No. 6502.

According to Article 73/A of Law No. 6502, in disputes heard in consumer courts, recourse to mediation before filing a lawsuit is a prerequisite. However, mandatory mediation does not apply to disputes within the jurisdiction of consumer arbitration boards and appeals against decisions of consumer arbitration boards.

In a lawsuit filed in consumer court, claims can be made for the return of the unjustly charged amount, legal interest, damages due to defective service, in some cases moral damages, and court costs. If the dispute is not only about the invoice amount but also involves medical error, wrongful treatment, or health harm, the malpractice and compensation aspects should be evaluated separately.

What claims can be made due to an unfair bill?

The main claims that can be made in a private hospital due to unfair billing or exorbitant fees are as follows:

A refund of unjustly charged fees can be requested. This request arises in cases where the legal limit for additional charges is exceeded, fees are charged for services that are not eligible for additional charges, services not performed are included in the invoice, or material costs exceed market rates are charged.

A refund of the overpayment, along with legal interest, can be requested. This claim for interest is particularly important if the patient or their relatives made the payment under duress during an emergency, and if the payment items are later found to be illegal.

Detailed invoices and records may be requested. If a private hospital refuses to provide the documents requested by the patient, this should be raised as both an administrative complaint and a legal action. The Private Hospitals Regulation mandates the issuance of a document detailing the healthcare services provided to the patient and showing the unit prices.

Allegations of defective service or unfair business practices can be made. Consumer law comes into play if a fee is charged without the patient being informed beforehand, items not included in the package are added later, the price is concealed, or the scope of the service is described misleadingly.

How should evidence be collected?

Gathering evidence is crucial in private hospital billing disputes. Patients or their relatives should not leave the hospital without obtaining the necessary documents after making a payment. The invoice, detailed breakdown, payment receipt, credit card slip, medical summary, service agreement, price information form, social security provision information, patient records, and list of materials used must all be obtained.

In emergency department files, triage records, emergency assessment, observation forms, notification forms regarding the end of the emergency, and referral or admission records are also important. Since the Social Security Institution's (SGK) information on emergency health services clearly indicates the application authorities if fees are charged under emergency procedures, obtaining these records is particularly important in emergency visits.

If the hospital does not provide the necessary documents, a written application should be submitted. If the application remains unanswered, the Provincial Health Directorate and consumer law avenues should be pursued. Additionally, by checking the SGK (Social Security Institution) treatment information via e-Government, it is possible to see which procedures the hospital billed to SGK. This record can show the difference between the fee charged to the patient and the procedures reported to SGK.

Conclusion: Private hospital bills must be examined in detail

Charging high fees in private hospitals is not always illegal; however, the hospital's right to charge fees is not unlimited. In private hospitals contracted with the Social Security Institution (SGK), additional fee limits, healthcare services for which additional fees cannot be charged, and emergency procedures must be considered. Fee charges in emergency situations, intensive care, cancer treatment, neonatal services, hemodialysis, and similar areas should be examined separately and carefully.

Private hospitals are required to provide patients with an invoice and a detailed breakdown of services provided. The invoice must include a detailed breakdown of the healthcare services rendered and their unit prices. Furthermore, the prices of medications and medical supplies cannot exceed market rates.

Patients who suspect an unfair bill or exorbitant fee should first request detailed invoices and records from the private hospital, then submit a written refund request to the hospital. For disputes covered by the Social Security Institution (SGK), they should apply to the SGK Provincial Directorate, and for patient rights and inspection matters, to the Provincial Health Directorate. Depending on the monetary limit, they should pursue legal action through the Consumer Arbitration Board or the Consumer Court. For consumer disputes under 186,000 TL in 2026, the Consumer Arbitration Board should be considered; for disputes of this amount and above, mandatory mediation and Consumer Court proceedings should be evaluated.

Therefore, a strong legal process regarding private hospital bills is successful not only based on the claim of "overcharging," but also through a comprehensive examination of factors such as social security coverage, additional fee limits, emergency situations, services for which additional fees cannot be charged, detailed billing records, payment documents, and hospital records.
