1. Medical Criminal Matters | Concept

Medical criminal liability refers to a situation in which a medical professional, such as a physician or nurse, or a medical institution comes to bear criminal liability for a violation of the Criminal Act, the Medical Service Act, or related statutes in the course of treatment or operation.
Unlike an ordinary medical dispute, a medical criminal matter is a legal area in which the question of whether the conduct of a medical professional or medical institution constitutes a crime is at issue, so that an investigative agency becomes involved and the matter may lead to criminal punishment.
As a representative example, where serious harm results to a patient from a medical professional's negligence, the crime of occupational negligence causing death or injury may apply.
A medical criminal case is not limited to the negligence of an individual medical professional.
Criminal liability may also arise where a medical institution has violated the law, and in such a case, the medical institution itself or the responsible person concerned becomes subject to criminal punishment.
2. Medical Criminal Matters | Main Types
Medical criminal matters are an area in which criminal punishment may be imposed for various unlawful acts beyond medical negligence.
It applies broadly, from accidents arising from a simple mistake to intentional unlawful acts, and the main cases in which a medical practitioner receives criminal punishment are as follows.
Occupational Negligence Causing Death or Injury Through Medical Negligence
Where a medical professional's negligence results in the death of or injury to a patient, the professional is punished for occupational negligence causing death or injury under Article 268 of the Criminal Act.
▶ Requirements for Establishment
② Existence of occupational negligence (breach of the duty of care)
③ Occurrence of a result (injury or death)
④ Causal relationship between the negligence and the result
▶ Related Precedents
A representative example is a case in which a medical professional fails to fulfill the duty of care during the ordinary course of treatment or surgery, resulting in organ damage, excessive bleeding, or the like.
An investigation is commenced upon a criminal complaint by the patient or an accusation by the bereaved family, and whether negligence exists is determined through an appraisal procedure centered on the medical professional's treatment judgment and the appropriateness of the medical practice.
▶ Article 268 of the Criminal Act
Death or Injury Caused by Occupational or Gross Negligence | Imprisonment without labor for up to 5 years or a fine of up to 20 million won |
Preparation of False Medical Certificates and Similar Documents
Where a medical practitioner falsely prepares a diagnosis, an autopsy report, or a certificate, the practitioner is punished under Article 233 of the Criminal Act.
For example, this applies where a medical practitioner prepares an injury diagnosis for the purpose of insurance fraud, or prepares a false hospitalization record even though hospitalization was not actually necessary.
Because medical documents have significant legal effect, false preparation is dealt with strictly, and a sentence of imprisonment may be imposed.
▶ Article 233 of the Criminal Act
Preparation of a false diagnosis and the like | Imprisonment with or without labor for up to 3 years, suspension of qualification for up to 7 years, or a fine of up to 30 million won |
Forgery and Use of Documents
Forging medical records, prescriptions, or similar documents, or actually using a falsely prepared document, is punishable under the Criminal Act.
For example, this includes cases in which, in the course of operating a medical institution or responding to a subsequent dispute, treatment dates are falsely manipulated, or medical records are prepared and submitted as if a procedure that did not exist had been performed.
▶ Level of punishment
Forgery or alteration of private documents and the like (Article 231 of the Criminal Act) | Imprisonment for up to 5 years or a fine of up to 10 million won |
Preparation of a private document by unlawful use of another's title (Article 232 of the Criminal Act) | Imprisonment for up to 5 years or a fine of up to 10 million won |
Prohibition of Disclosure of Information
Where a medical professional or a worker at a medical institution discloses or announces externally a patient's health information learned during treatment, they are subject to criminal punishment under Articles 19 and 88 of the Medical Service Act.
For example, this applies to disclosing a celebrity's diagnosis or treatment details on social media or the like, or a case in which an internal staff member of a medical institution provides a patient's information to a third party without justifiable grounds.
It is also regarded as a violation of the medical professional's professional ethics, and beyond punishment, it may also lead to administrative dispositions such as license suspension.
▶ Article 19 of the Medical Service Act (Prohibition of Disclosure of Information)
▶ Level of punishment
Article 88 of the Medical Service Act | Imprisonment for up to 3 years or a fine of up to 30 million won |
Crime of Fraud (False Billing of Medical Fees and Other Charges)
Where treatment costs are overcharged through false medical records, or where nonexistent procedures are billed, the crime of fraud under Article 347 of the Criminal Act applies.
Representative cases include false billing of treatment costs to the National Health Insurance Service or automobile insurers, false hospitalization, and the mobilization of fake patients.
▶ Criminal Act, Article 347
Fraud | Imprisonment for not more than 20 years or a fine of not more than 50 million won |
3. Medical Criminal Matters | How to Respond to an Investigation

For a medical practitioner, a medical criminal case can be a serious matter that goes beyond a simple criminal procedure and is directly tied to professional survival, such as suspension or revocation of a license.
Therefore, accurate exercise of rights and a careful response from the early investigation stage are essential.
Basic Principles of Investigation
Where a person has been booked as a suspect, the principle is that the investigation proceeds without detention.
Under Article 198 of the Criminal Procedure Act, the investigation of a suspect must, as far as possible, be conducted without detention, and the investigative agency must respect the human rights related to the suspect and thoroughly maintain confidentiality.
This serves as a minimum line of defense in an investigation procedure that can deal a serious blow to a medical professional's honor and professional standing.
Notification and Exercise of the Right to Remain Silent
A suspect may refuse to make a statement during questioning by an investigative agency.
The Constitution and the Criminal Procedure Act guarantee a suspect the right to refuse to make a statement, and before interrogating a suspect, an investigative agency must notify the suspect of the following matters.
• That the suspect will not suffer any disadvantage even if they do not make a statement
• That if the suspect waives the right to remain silent and makes a statement, it may be used as evidence of guilt in court
• That the suspect may receive the assistance of counsel during questioning
Retaining Defense Counsel
A suspect may appoint defense counsel at any time and have counsel present during questioning.
Under Article 30 of the Criminal Procedure Act, not only the suspect but also the legal representative, spouse, and lineal relatives may appoint defense counsel.
In addition, absent special circumstances, the investigative agency must allow the participation of defense counsel during the questioning of the suspect.
This is an important safeguard that allows a person to carefully decide the direction of their statements with the assistance of defense counsel from the early stage of the investigation.
4. Medical Criminal Matters | Settlement

In medical criminal cases, a settlement plays a very important role in resolving the dispute amicably and adjusting the level of criminal punishment.
Significance of Settlement
In criminal cases such as assault and infliction of bodily injury, a victim may file a criminal complaint or accusation against the perpetrator, but the victim is also guaranteed the right to withdraw the complaint or accusation.
In particular, one of the grounds for withdrawing a complaint or accusation is an amicable settlement between the victim and the person complained against.
Therefore, in medical criminal cases, settlement with the victim can significantly affect not only the level of criminal punishment of the medical professional or medical institution, but also the future possibility of maintaining the license and continuing to practice medicine.
Methods of Settlement
There is no specific form prescribed by law for the method of settlement, but it generally proceeds through the following steps.
② Both parties sign and seal a settlement agreement to put the terms of the settlement in writing.
③ The settlement of the civil damages portion and the portion relating to criminal punishment may be conducted separately, or they may be conducted together as one.
Effect of Settlement
In the case of a crime that is not a crime not punishable against the victim's will, such as occupational negligence causing injury in medical practice, where the matter does not turn on the victim's intent regarding punishment, the criminal procedure proceeds regardless of the victim's intent.
However, where a settlement with the victim has been reached, the prosecutor and the court reflect this as a favorable circumstance in determining the sentence.
In addition, if an application for a compensation order is granted during the criminal proceedings, the issue of damages for the victim can be resolved simultaneously in the criminal trial, without a separate civil litigation procedure.
A compensation order is a system under which, upon a guilty verdict in a criminal trial, the defendant is ordered to compensate for the harm caused by the crime. The victim can obtain damages conveniently within the criminal procedure, without a separate civil litigation.
5. Medical Criminal Matters | Systematic Response and Legal Support
Medical criminal cases may lead not only to criminal punishment but also to serious administrative dispositions, such as suspension or revocation of the license of a physician or medical institution worker, so they are matters directly connected to one's livelihood beyond a mere legal response.
