Medicare Part B
メディケアパートB(医療保険) (medikea pāto B (iryō hoken))
Medicare Part B covers outpatient medical services including doctor visits, preventive care, outpatient surgery, durable medical equipment, and certain laboratory tests. Part B requires a monthly premium (income-adjusted) and has an annual deductible, after which Medicare pays 80% of approved costs and the enrollee pays 20% (with no out-of-pocket cap unless supplemented by Medigap). Late enrollment penalties apply if Part B is not enrolled in promptly when first eligible.
Part B works alongside Part A; together they form 'Original Medicare,' which most beneficiaries supplement with Medigap or Part D coverage.
