Article 41 of the National Health Insurance Act, checked in MST 276651 effective January 2, 2026, places examinations and tests within medical-care benefits while allowing the ministry to designate non-covered subjects. Article 44 and Article 19 of the Enforcement Decree, checked in MST 283469 effective February 19, 2026, establish that the patient's share follows the applicable rules and Annex 2 structure. Those provisions do not create one universal outpatient percentage for every echocardiogram.
HIRA's published cardiac-ultrasound criteria explain that a physician may find a study medically necessary when cardiac disease exists or is suspected, but coverage still depends on the study type, diagnostic or follow-up purpose, age, procedure context, and recognized frequency. Adult diagnostic use, specified follow-up circumstances, post-procedure limited studies, pediatric rules, and preoperative-risk circumstances have separate conditions. Some excess-frequency studies may be selective benefits with an 80% patient share, while another study can be non-covered when the benefit criteria are not met and the required explanation and consent process applies.
Because those conditions require a clinical record, the calculator does not ask the user to self-diagnose or infer eligibility from a symptom checkbox. The safe input is the gross covered or selective-benefit amount and the exact copay rate confirmed by the provider's billing office for this test. If the classification has not been confirmed, leave it as unconfirmed and use the warning as a call checklist.
The current detailed benefit-criteria notice, Notice No. 2026-169 effective July 31, 2026, and the current service list and relative-value notice, Notice No. 2026-160 effective July 31, 2026, were rechecked for this implementation. Their latest amendments did not supply a universal echo price or a new automatic coverage formula appropriate for this calculator.
