Is the Part B deductible per year or per visit?

A deductible is the amount you pay before Medicare starts sharing covered costs. For Part B, you pay this deductible once each calendar year, and in 2026 it is $283. After you meet it, you generally pay coinsurance, your share of the cost, for covered services for the rest of the year rather than starting the deductible over at each appointment. This is different from Part A, where the inpatient deductible applies per benefit period and can occur more than once a year. So with Part B, the $283 is a single yearly amount that resets at the start of each new calendar year.
