Where private health insurance stops on cosmetic treatment

The short answer: cosmetic treatment is not covered by Korean private indemnity health insurance. Softening wrinkles with botulinum toxin, restoring volume with filler, clearing pigment with a laser — all of it sits outside. Not because insurers are strict, but because the policy is built to cover the cost of treating illness and injury.
The same treatment splits on purpose
The confusion comes from the fact that the same procedure names are also used therapeutically.
- Botulinum toxin — crow's feet is cosmetic; pathological sweating or eyelid spasm is treatment.
- Lasers — clearing spots is cosmetic; burn scars or vascular lesions are viewed differently.
- Eyelid surgery — a crease is cosmetic; skin heavy enough to obstruct vision can be recognised as treatment.
What decides it is not the procedure name but the diagnosis and the medical need — and that call is made by the clinical record, not by the insurer.
When you bought the policy changes what it covers
Coverage and the patient's share differ by the generation of policy sold. Two people can both say "I have indemnity cover" and hold quite different contracts. There is no shortcut around reading your own policy. A case you read online is a story about someone else's contract.
What to settle before treatment
- Ask what diagnosis will be recorded. Whether a claim is possible is decided there.
- If the purpose is cosmetic, the receipt shows it as non-covered. That is normal, not an error.
- If you are told it is therapeutic, check that the reasoning is written into the certificate or report. A verbal explanation cannot be filed.
- Ask your insurer before the appointment, not after.
When a clinic offers to "handle the insurance"
Filing a cosmetic procedure under a therapeutic diagnosis is insurance fraud, and a patient who goes along with it carries liability too. Cases keep surfacing. The more advantageous an offer sounds, the more carefully check that the diagnosis matches what actually happened.
This explains how the scheme is built; whether your own contract covers a given case is a matter for your policy wording and your insurer.
