Vincent Murray · Answer

Medicare Part B covers most medically necessary blood tests and other diagnostic tests. To qualify, a person’s doctor must write an order for the test.

If an individual is admitted to a hospital as an inpatient, Medicare Part A will cover the costs of blood work.

Medicare Advantage, or Medicare Part C, is an alternative to Original Medicare. Private insurers administer Medicare Advantage plans, and the plans comprise parts A and B benefits and often also include prescription drug coverage and additional benefits like optical or dental care.

Like parts A and B, Medicare Advantage plans cover the costs of blood work and other tests.

Justin Doherty · Answer

Medicare as a whole operates on a "medically necessary" basis. If your blood tests are considered medically necessary, they are typically covered under Part B. However, if you receive blood test that are considered "elective", they are not likely to be covered. These would include situations where you might be required to have blood tests for employment purposes.

No! 

There are local and national coverage determination set by Medicare that serve as the guidelines that every provider and payer must follow. If there isn't a Medicare coverage determination, a Medicare Advantage Plan may have their own coverage determination based on evidence based care and established clinical guidelines. 

If you have a question about a specific test you are considering, I always recommend checking in  1 of 2 spots. 

1. Medicare Website (www.medicare.gov) and look up the test and cost information. This ensures that it will be covered and reduce your risks of paying for non-covered blood test. 

2. If you have a Medicare Advantage plan, you can also review the blood test and coverage information through their website / member portal or simply reaching out to member services.   


Most labs/hospital/clinics are aware of which blood test are covered by Medicare and if there are concerns, they will typically make you aware it is not covered, explain the potential cost of the blood test if it is not covered, and may have you sign a document explaining that you will be responsible for the cost of the uncovered test if the claim is denied. This will avoid a financial loss to the clinic/lab, and will avoid an unexpected out of pocket cost to you as a member.  

If there are any questions or doubt, verify with the Medicare before proceeding with any potentially not covered blood test.

Chad Sickle, RN · Answer

Yes, any blood tests that your provider orders will be covered if covered under Medicare. This includes about 99% of all tests. Be sure to have them done in network if you are on a Medicare Advantage plan.

Jeffrey Jon · Answer

I am not sure about “all types of blood tests,” but Medicare  will cover many tests which will include blood testing. Go to Medicare.gov to find specific information.

David Quintal · Answer

Generally speaking, yes Medicare covers all medically necessary blood tests ordered by your healthcare providers.  
Covering these blood test allows your healthcare professional to track your health and even screen for disease prevention.
Medicare Advantage plans (Part C) may cover more blood tests than original Medicare (Part a and Part B).  Under original Medicare, there is no separate fee for blood tests.

David Didier · Answer

Your Medicare (parts A and B) covers most medically necessary blood tests.

Usually, you do not need to pay for a diagnostic blood test. 
However, the plan deductible and 20% coinsurance may apply.


Medicare Advantage (Part C plans) also cover blood tests, and coinsurance and copayments may apply.  Thx!

Kimi Oliveira · Answer

No all blood tests are not covered by Medicare.   You need to work with your agent and doctor to determine what order is being placed for your blood test.

Steven Bleicher · Answer

I wish folks were coached more about this amazing fact of Medicare: There are over 60,000+ treatments & procedures that are currently covered by Medicare. As long as a procedure has a dollar value that has been put in place on it and is not an experimental treatment, it WILL be deemed as being covered with the same 80/20% ratio. 80% is covered by your primary insurance (and most or all of the remaining 20%) by secondary insurance.

Medicare cover blood test. I have never heard of any restriction on the blood test after prescribed by a doctor being done by Medicare.

Kris Moen · Answer

Medicare will pay for bloodwork when there’s a reason for it—but they’re not big fans of "let’s just test everything and see what happens".

Thomas Magnus, RHU · Answer

Medicare operates on the concept of "Medical Necessity". If your doctor believes a blood test is necessary in order to diagnose a condition you are experiencing, it should be covered by Medicare Part B. https://www.hhs.gov/answers/medicare-and-medicaid/what-does-medicare-part-b-cover/index.html

Everything is subject to medical necessity.  If you have a particular blood test in question.  Consult your doctor's office.  They can assist in determining what's covered.

Pat Papson · Answer

Good Morning,

Are you talking about Original Medicare?

Or with a Supplement or an Advantage plan?

Original Medicare has a plan deductible and co-pays.

Best to check with Medicare before you have your tests, so you are not surprised with the costs.

Lillian Hill · Answer

A good rule of thumb to follow is that if it is medically necessary and ordered by a primary care provider, Medicare will most likely approve it. If it is cosmetic or elective, it is unlikely to be approved. However, be sure to discuss it with your medical team whenever you have questions.

Good question.

Not all blood tests are covered by Medicare — but many essential ones are, especially if they're considered medically necessary.

Covered by Medicare Part B (if medically necessary):

Complete Blood Count (CBC)

Lipid Panel (cholesterol and triglycerides)

A1C Test (for diabetes)

Blood glucose tests

Thyroid function tests

Prostate-Specific Antigen (PSA) (for prostate cancer screening)

Liver and kidney function tests

Hepatitis screenings

HIV and STD screenings (in certain cases)


Not typically covered:

Tests for employment, life insurance, or general curiosity

Experimental or non-FDA-approved blood tests

Some vitamin or hormone level tests (unless deemed medically necessary)


To be covered, the test must be ordered by your doctor and used to diagnose, monitor, or treat a medical condition. Preventive screenings like cholesterol or diabetes tests are often covered 100% under Medicare if you qualify.

Christopher Akers · Answer

No. Medicare does not cover all blood tests. It covers medically necessary diagnostic blood tests and certain preventative blood tests. Your doctor can discuss why a blood test is being recommended for you and you can ask if it is medically necessary by Medicare.

If a blood test is ordered by your doctor. The blood test would be covered. However, depending on what type of Medicare plan there may be a cost.

Sherri Haskell · Answer

Medicare covers blood tests when they are medically necessary or specifically approved preventive screenings, but it does not cover every routine lab panel.

If the test is covered, Original Medicare typically pays 80% of the Medicare-approved amount after the Part B deductible for many outpatient lab tests, unless the test is one of the preventive services Medicare covers at 100%. Medicare Advantage plans must cover at least the same Medicare benefits, but they may have different copays or network rules
