Until the end of the fiscal year the child turns 18, the out-of-pocket share of insured care is subsidized

For children living in Chofu City and enrolled in health insurance, from age 0 until the first March 31 on or after the day they turn 18, the city subsidizes the out-of-pocket share of medical care and pharmacy dispensing covered by health insurance. At participating medical institutions in Tokyo, show your My Number health insurance card or eligibility confirmation certificate and the medical certificate (iryōshō) at the counter. If you see a doctor outside Tokyo or similar, pay first and then apply for a refund with the receipt (within 5 years from the day after you paid the medical costs). Meal costs during a hospital stay and costs not covered by health insurance are excluded. If you apply within 3 months of the birth or moving in, the subsidy is applied retroactively to that date.
