Your Medicare Coverage

Is my test, item, or service covered?

Laboratory services (clinical)

How often is it covered?

Medicare Part B (Medical Insurance) covers medically necessary clinical diagnostic laboratory services that are ordered by your doctor or practitioner. Laboratory tests include certain blood tests, urinalysis, tests on tissue specimens, and some screening tests. They must be provided by a laboratory that meets Medicare requirements.

Who's eligible?

All people with Part B are covered.

Your costs in Original Medicare

You pay nothing for Medicare-approved covered clinical diagnostic laboratory services.


Your doctor or other health care provider may recommend you get services more often than Medicare covers. Or, they may recommend services that Medicare doesn’t cover. If this happens, you may have to pay some or all of the costs. It’s important to ask questions so you understand why your doctor is recommending certain services and whether Medicare will pay for them.
