Medicare Coverage of Blood Tests


What It Is

Blood testing by a laboratory

What's Covered

The basic Medicare rule regarding blood tests is that Medicare covers the drawing of blood and laboratory testing, reasonably ordered by a physician or other appropriate practitioner, to diagnose or monitor a particular disease or condition. But Medicare does not cover routine blood tests ordered as part of a general physical examination or screening.

If a medically reasonable diagnostic blood test is performed on an inpatient in a hospital or skilled nursing or rehabilitation facility, Medicare Part A covers it. If the test is performed on an outpatient, in any setting, Medicare Part B covers it.

If you have a Medicare Part C Medicare Advantage plan: Medicare Part C Medicare Advantage plans, also called Medicare Advantage plans, must cover everything that's included in original Medicare Part A and Part B coverage. But sometimes a Part C plan covers more, with extra services or an expanded amount of coverage. (Co-payments for Part C plans may also be different than those for Part A or Part B.) To find out whether your plan provides extra coverage or requires different co-payments for blood tests, contact the plan directly.

What Medicare Pays

If Medicare Part A covers a blood test for an inpatient, the cost of the testing becomes part of the overall covered hospital charges. Medicare Part A payment for inpatient hospital charges is subject to a deductible and to daily co-payments for stays of 60 days or more.

If Medicare Part B covers an outpatient blood test, the amount it pays depends on where the patient gets the testing. If a patient has a covered blood test at a Medicare-certified independent laboratory, Medicare Part B pays the full cost. If the testing is performed by a hospital outpatient department, Medicare pays the full cost except for a patient co-payment. The amount of the co-payment depends on the geographic location of the hospital and the type and amount of testing done.

Important: Regardless of the rules regarding any particular type of care, in order for Medicare Part A, Medicare Part B, or a Medicare Part C plan to provide coverage, the care must meet two basic requirements:

  • The care must be "medically necessary." This means that it must be ordered or prescribed by a licensed physician or other authorized medical provider, and that Medicare (or a Medicare Part C plan) agrees that the care is necessary and proper. For help getting your care covered, see FAQ: How Can I Increase the Odds That Medicare Will Cover My Medical Service?

  • The care must be performed or delivered by a healthcare provider who participates in Medicare.

I have several doctors and they ask for separate blood tests for different conditions. Sometimes these tests come within a couple months of each other. Does medicare cover both tests?

I got several blood tests at UMC in Tucson. Sign says all fee paid up front. I paid the fees of about $55. A few weeks late I get a bill for $106 for doctors having to read the results. I have had many many tests there and never goy this charge. My doctor can resd them fine himself. I can read then fine my self as I always get my own copy fro UMC. I never authorized these charges, were never charged these charges, and nowhere even in small print does it say anything about this. I have no insurance so they gave me a fair price on the blood tests. But, I'm enreged over this new bill. DO I HAVE TO PAY THIS?
