Key takeaways
Pause when a discount is linked to recruiting another patient, a cash rebate is offered after payment, or a cosmetic procedure is to be recorded as a covered treatment. Public investigations and reports citing the Financial Supervisory Service describe these patterns.
Advertising or a discount is not automatically unlawful. Korean court decisions show that the consideration paid, the referral structure, the audience, and the full facts must be examined. This guide is a pre-consultation checklist, not legal advice.
Five warning signs
1. A discount or reward is offered on the condition that you introduce another person to a particular clinic.
2. Part of an inflated payment is promised back in cash after treatment.
3. Someone proposes recording a cosmetic procedure as manual therapy or another covered treatment for indemnity insurance.
4. A large discount or free procedure depends on writing a review, bringing a friend, or being among the first applicants. Check the detailed conditions rather than treating the discount percentage alone as proof of illegality.
5. The person advising you will not clearly identify whether they work for the clinic. Verify the clinic separately and call its published main number.
In one line
Check referral demands, rebates, false insurance coding, conditional discount ads, and the adviser’s affiliation together; legality depends on the consideration and the actual referral structure.
A discount tied to a paid referral can raise a Medical Service Act issue
Article 27(3) prohibits for-profit introduction, arrangement, or solicitation of patients. A Korean Hospital Association notice describes a mileage program that rewarded both the patient and the person who introduced them.
The Supreme Court has upheld a case in which a platform connected patients to named clinics and received a percentage of treatment fees. The third-party referrer and a medical professional who directed the scheme can both fall within the provision.
Reported payback schemes returned 20–40% of the payment
A report citing National Assembly Research Service analysis describes schemes in which fees were inflated and 20–40% was returned in cash after an insurance claim.
The same report said no Medical Service Act punishment for medical-fee paybacks was identified from January 2015 through March 2026. That finding does not make the conduct lawful; it shows why refusing the proposal before payment is safer.
Changing cosmetic treatment records for insurance is a documented fraud pattern
A report on the Financial Supervisory Service’s September 2025 warning describes cosmetic skin treatments falsely recorded as manual therapy. About 270 people were reportedly detected in this category.
Patients who agree can also become involved in an insurance-fraud investigation. A 2026 report says the FSS and HIRA agreed to analyse claims jointly for suspicious patterns.
Conditional extreme discounts were a government inspection target
The Ministry of Health and Welfare reported reviewing 4,693 online medical advertisements in 2017, identifying 1,286 suspected violations associated with 318 institutions. Patient-attraction advertising accounted for 1,134 items in that review.
Examples included large non-covered-service discounts, free add-ons, benefits for bringing another person, first-come conditions, and treatment subsidies. A Supreme Court decision also makes clear that medical advertising is not automatically patient solicitation, so audience, conditions, and consideration must be examined together.
Verify both the clinic and the adviser’s affiliation
Use HIRA’s hospital search to verify the institution, then call the clinic’s published main number to ask whether the adviser is an employee or authorised representative.
Be cautious when someone requests money for a connection, repeatedly recommends only one clinic, or refuses to let you compare alternatives.
Quick checks by situation
“Refer someone and we will discount your fee” — check whether consideration is tied to patient referral.
“We will return part in cash” — treat it as a payback warning and check whether the fee or insurance claim is inflated.
“We will make the paperwork eligible for insurance” — do not agree to a record that differs from the treatment actually received.
“Half price” or “free for a review” — verify all conditions; do not decide legality from the headline discount alone.
“I do not know who this adviser works for” — verify the institution on HIRA and call the official number.

Frequently asked questions
What exactly is a clinic broker?
It is a common description, not a separately defined statutory title, for a third party that connects patients to a particular clinic for profit. Whether conduct violates Article 27(3) depends on the consideration, referral structure, and facts.
Is a referral linked to a treatment discount illegal?
It can raise an Article 27(3) issue when a discount is tied to a compensated referral. Advertising or discounting alone is not automatically unlawful, so the recipient, payment, and referral arrangement must be checked.
Is it safe to record a cosmetic skin procedure for indemnity insurance?
No one should ask you to record a treatment under a false name. A report on the FSS warning describes cosmetic procedures recorded as manual therapy, with about 270 people reportedly detected in that category.
Is a post-treatment cash rebate safe?
A report citing National Assembly Research Service analysis describes paybacks of 20–40% of the payment. A lack of detected punishment in the reviewed period does not mean the arrangement is lawful or safe.
How can I verify whether an adviser belongs to a clinic?
Verify the institution in HIRA’s hospital information service and ask the clinic through its independently published main telephone number whether the person is an employee or authorised representative.
