What's changing?

The "selected medical treatment" system for long-listed drugs is expanding with 34 new additions, totaling 775 items. When patients choose a brand-name drug over a generic equivalent, they must pay an extra 25% (1/4) of the price difference out of pocket.

⚙️ How it works

  • Covers 775 brand-name drugs that have generic equivalents
  • Choose brand-name → pay 1/4 of the price difference extra
  • Choose generic → no extra charge (same as before)
  • If medically necessary, doctor can waive the extra charge

💰 Example

Brand-name: ¥200/tablet, Generic: ¥80/tablet. Difference ¥120 × 1/4 = ¥30 extra. At 30% copay: normal ¥60 + extra ¥30 = ¥90 total.

👥 Who's affected?

  • Foreign residents with chronic conditions requiring regular prescriptions
  • Those on medications for hypertension, diabetes, high cholesterol, etc.
  • Anyone specifically requesting brand-name prescriptions
  • All national health insurance / social insurance enrollees

💸 How to reduce your burden

  • Ask your doctor about switching to generics
  • Tell the pharmacy "generics are OK"
  • Check your medication handbook to see if your drugs are covered
  • Consult your doctor if there's a medical necessity
