The Medicare deductible for Part B medical insurance is $147 per year as of 2015. In addition, most people also pay a monthly premium of $104.90. You must pay the Part B deductible each year before Medicare covers most medical expenses, and you usually must pay a percentage of costs after the deductible. However, some medical expenses are free under Part B and aren't subject to the deductible.

Part B Coverage

Medicare Part B covers medically necessary services, such as doctor visits or laboratory tests, and medically necessary supplies like crutches. It also covers some preventive services, such as an annual wellness visit and a flu shot. Additionally, it covers tests for early diagnosis of a medical condition.

Medically necessary preventive services are free without any deductible if the health care provider accepts assignment. Assignment means the provider agrees to accept Medicare's payment as payment in full.


Advantage Plans

Medicare Advantage plans must offer at least as much medical coverage as original Medicare Plan B, and some offer more. Advantage plans may charge a different premium and a different deductible for medical insurance.
