Why is Medical Expense Support for Rare Diseases Necessary?
Rare diseases have small patient populations, making treatment development slow, and diagnosis and treatment processes incur substantial medical costs. Medical expenses can be 5 to 10 times higher than common illnesses, causing many patient families to face economic hardship. In 2026, the government is implementing multiple support programs to ease the burden on these patients. Medical expense support for rare disease patients is not simply providing partial cost coverage, but is designed to offer practical assistance throughout the entire treatment process.

The Health Insurance Review and Assessment Service recognizes approximately 400 rare diseases. Major eligible diseases include:

Rare Disease Medical Expense Support Programs and Coverage
The three main support programs for 2026 are:
1) Rare Disease Calculation Exception Program
Patients diagnosed with rare diseases significantly reduce their out-of-pocket cost-sharing ratio under national health insurance. While the typical out-of-pocket rate for medical services is 20-30%, those eligible for calculation exceptions see costs decrease to 5-10%. This applies to hospitalizations, outpatient visits, and medication expenses, allowing patients to save millions of won annually in medical costs.
2) Medical Expense Support Funds (Financial Support)
Some rare disease patients receive additional direct government medical expense support. Eligible recipients include those receiving basic livelihood guarantee benefits, lower-middle income earners, and households with income at or below 180% of the median. Support amounts vary by disease but can reach 5 to 20 million won annually. In particular, patients receiving expensive new drugs or gene therapy can receive full coverage of out-of-pocket expenses.
3) Patient Cost Relief at Medical Institutions
When treated at designated rare disease specialty medical centers, patients receive discounts on medical costs. Additionally, some coverage may apply to expensive genetic tests or imaging studies required for diagnosis.

Essential Tips to Know When Receiving Rare Disease Medical Expense Support
Be Sure to Confirm Before Receiving Support
- International Diagnosis Recognition: Even if diagnosed abroad, you can apply after additional diagnosis at a domestic medical institution
- Re-diagnosis and Renewal: Calculation exception approval requires renewal every 3 years. Applying before renewal ends ensures no gap in benefits
- Freedom of Hospital Choice: After calculation exception approval, you receive benefits at any hospital, so you can freely choose a medical institution that suits you
- Medication Expense Support: Rare disease treatment drugs listed under insurance automatically receive discounts. Unlisted new drugs can receive support through separate application
- Confirm Income Criteria: To receive medical expense support funds, you must meet income standards. Even if above the standard, you can still benefit from reduced out-of-pocket costs through the calculation exception
Practical Cost Reduction Cases
For Spinal Muscular Atrophy (SMA) patients, average monthly medical costs for new drug treatment are approximately 30 million won, but after applying the calculation exception, out-of-pocket costs decrease to 3-5 million won monthly. With additional medical expense support, out-of-pocket costs can be reduced to 1-2 million won monthly. This means reducing annual economic burden by over 30 million won.
Additional Support Programs and How to Obtain Information
Support for rare disease patients extends beyond medical expenses. Living expense support, psychological counseling, and medical supply assistance are available through various programs. Joining rare disease patient networks or patient associations provides information on new drug treatments, updates on medical expense support programs, and counseling services.
Additionally, calling the Ministry of Health and Welfare Rare Disease Counseling Center (1577-3392) provides detailed guidance on support programs and application methods tailored to your condition. Since this is a free service, you can contact them anytime.
