In Chuo City, the out-of-pocket cost when children from age 0 to the first March 31 after turning 18 receive insured treatment at a medical institution is fully subsidized, with no income limit and no cost to you. Meal costs during hospital stays are also covered. If you show the medical certificate together with your My Number health insurance card (or eligibility certificate, etc.) at the counter of a medical institution or pharmacy in Tokyo, there is no out-of-pocket cost. If you receive care outside Tokyo or similar, pay first and then apply to the city for a refund (within 5 years of the receipt date).
