Part B Helps Cover These Items and Services
Part B covers certain medical items and services no matter how you get your Medicare health care. Costs for these services vary depending on the plan you choose. For More specific costs and other information about these services, see: What you pay for the Original Medicare Plan in 2026 - Part B. For most of these items and services, you must pay a Copayment or Coinsurance, and a Deductible may apply.

Section: Part B Helps Cover... is an alphabetical list of common items and services Medicare covers if they are either:

Medically Necessary--This means the item or service is needed for the diagnosis or treatment of your medical condition,
or
Medicare-covered Preventive Services--like exams, lab tests, and screening shots to help prevent, find, or manage a medical problem. Preventive services may find health problems early when treatment works best. Talk to your doctor about which preventive services you need and if you meet the criteria for coverage.

You can live a healthy lifestyle by exercising, eating well, keeping a healthy weight, not smoking, and using preventive services.

For a list of what isn't covered, see What isn't covered by Medicare Part A and Part B? .
