Korean special-case copay calculator

This guide translates the Korean special-case copay content. It compares ordinary copay with reduced copay for registered severe disease, rare disease, intractable disease, tuberculosis, burns, heart and cerebrovascular disease, trauma, and dementia categories.

Special-case reduction logic

The Korean source calculates two parallel burdens. The ordinary burden is covered medical cost multiplied by the treatment-type copay rate. The special-case burden is covered medical cost multiplied by the registered disease-group rate. The saving is the difference between those two covered copays.

Non-covered medical cost is added after the special copay because special-case registration only reduces covered benefits. It does not turn non-covered treatment into covered treatment.

Rates and treatment types

Cancer special-case care is modeled at 5 percent. Rare and intractable disease groups are modeled at 10 percent. Tuberculosis is modeled at 0 percent in the special-case path. Treatment-type ordinary rates include inpatient, clinic outpatient, hospital outpatient, general hospital outpatient, tertiary hospital outpatient, and pharmacy categories.

Because tertiary outpatient ordinary copay can be much higher than inpatient copay, the same severe-disease rate can create different savings depending on where and how the care is billed.

Covered versus non-covered costs

The covered-cost input should include only the National Health Insurance covered amount before patient copay. The non-covered-cost input should include items outside the covered benefit schedule. Mixing the two will distort both the ordinary benchmark and the special-case result.

The result reports special copay, ordinary copay, saving amount, saving rate, total burden with non-covered items, and the ordinary total burden benchmark. These are the same structured outputs used by the Korean pure function.

How to use the estimate

Use the calculator before treatment to understand why special-case registration matters, and after receiving a bill to see whether the covered copay roughly matches the expected reduced rate. If the billed rate does not align, ask the hospital billing desk whether the special-case code was registered and applied.

Final eligibility depends on disease registration, benefit code, treatment period, and claim review. The calculator is not a substitute for NHIS or hospital billing confirmation.
