For 2015, the Medicare Part B deductible is $147 per year, according to Medicare.gov. Medicare Part A has a hospital inpatient deductible of $1,260 for each benefit period. The deductibles for Medicare Part C, or Medicare Advantage, and Medicare Part D, prescription drug coverage, vary by health plan.
Once the beneficiary pays the annual deductible amount for services covered under Part B, he pays a co-insurance fee of 20 percent of Medicare-approved costs for services received for the remainder of the year, explains My Medicare Matters. People with limited resources and income below the federal poverty limit can be exempted from paying either the deductible or co-insurance.
