The Medicare wellness exam includes a basic health assessment, but blood work is not automatically part of it
The Medicare Annual Wellness Visit is a free preventive care appointment covered by Medicare Part B. During this visit, your doctor reviews your health history, checks your blood pressure and weight, and screens for depression and cognitive problems. However, the wellness visit itself does not include routine blood work like cholesterol or glucose tests.
Blood work may happen on the same day as your wellness visit, but it is ordered separately and billed separately. Whether your doctor orders blood tests depends on your age, health history, and what your doctor thinks you need — not on the wellness visit itself.
Key Takeaways
- The Medicare wellness visit covers a physical assessment and health review but does not automatically include blood work.
- Blood tests ordered during the same appointment are separate services with their own coverage rules.
- Medicare covers certain preventive blood tests at no cost if your doctor orders them as part of preventive care, not as part of the wellness visit.
- Tell your doctor before the visit if you want blood work done, so they can schedule lab time and you know what to expect.
- If blood work is ordered for a specific symptom or condition rather than prevention, you may owe a copay or coinsurance.
What happens during the Medicare wellness visit
The wellness visit is a structured appointment that takes about 15 to 20 minutes. Your doctor will ask about your medical history, any medications you take, and whether you have fallen recently. They will measure your height, weight, and blood pressure, and calculate your body mass index (BMI).
Your doctor will also screen you for depression using a short questionnaire and may ask questions to check your memory and thinking skills. At the end of the visit, your doctor creates a personalized prevention plan that lists health screenings and vaccines you may need based on your age and risk factors. This plan is what guides whether blood work gets ordered — but the wellness visit itself does not include it.
Which blood tests Medicare covers without cost
Medicare Part B covers certain preventive blood tests at no cost to you when your doctor orders them as preventive care. These include screening for high cholesterol (lipid panel), diabetes (fasting glucose), and hepatitis B and C. The tests must be ordered by your doctor and performed at a Medicare-approved lab.
The key difference is why the test is ordered. If your doctor orders a lipid panel because you are 65 and have never had one, Medicare covers it with no copay. If your doctor orders the same test because you came in complaining of chest pain, it may be treated as a diagnostic test rather than preventive screening, and you could owe a copay or coinsurance.
Your doctor decides which tests are preventive based on your age, sex, and health history. Medicare's guidelines change, so ask your doctor which tests are covered at no cost during your visit.
When you might owe money for blood work
You will owe a copay or coinsurance if blood work is ordered to diagnose or monitor a specific condition rather than as preventive screening. For example, if you have diabetes and your doctor orders a hemoglobin A1C test to check your blood sugar control, you typically owe a copay. If you come in with symptoms and your doctor orders tests to figure out what is wrong, those are diagnostic tests, not preventive ones.
Some blood tests fall into a gray area. If you have risk factors for a condition — such as a family history of heart disease — your doctor may order preventive screening that Medicare covers at no cost. But if you already have the condition, the same test becomes a monitoring test and you owe a copay.
Before your visit, ask your doctor's office which tests they plan to order and whether each one will be covered at no cost. This prevents surprises on your bill later.
How to prepare for your wellness visit if you want blood work
Call your doctor's office at least a week before your wellness visit and tell them you want blood work done. Ask which tests they recommend for you and whether you need to fast (go without food or drink) before the appointment. Some blood tests, like fasting glucose or lipid panels, require you to fast for 8 to 12 hours beforehand.
If you need to fast, schedule your wellness visit for the morning so you do not have to wait all day without eating. Ask the office whether the lab is in the same building or if you will need to go somewhere else. Some offices draw blood during the visit; others send you to a separate lab.
Bring your Medicare card and a list of all medications and supplements you take. Tell your doctor about any recent symptoms or health changes, even if they seem minor — this helps your doctor decide which preventive tests make sense for you.
What to do if you receive a bill for blood work
If you get a bill for blood work you thought would be free, do not ignore it. Call the lab or your doctor's office and ask why the test was not covered. Ask them to explain whether it was billed as preventive or diagnostic.
If you believe the test should have been covered at no cost, you can file an appeal with Medicare. You have 120 days from the date on the bill to appeal. Contact Medicare at 1-800-MEDICARE (1-800-633-4227) and ask how to file an appeal for that specific bill.
Keep copies of all bills and explanation of benefits (EOB) statements from Medicare. These documents show what was billed, how much Medicare paid, and what you owe. If the same issue happens again, you will have a record to show your doctor's office.
Frequently Asked Questions
Do I have to get blood work during my wellness visit?
No. The wellness visit itself does not include blood work. Your doctor may recommend tests based on your age and health, but you can decline. If you want blood work, ask your doctor whether it is medically necessary or optional, and whether Medicare will cover it at no cost.
Will I owe a copay if my doctor orders blood work during the wellness visit?
It depends on whether the test is classified as preventive or diagnostic. Preventive blood tests ordered by your doctor are covered at no cost. Diagnostic tests — ordered because of a symptom or existing condition — usually require a copay. Ask your doctor's office before the visit which tests are covered at no cost.
What if I have not had blood work in years?
Tell your doctor at your wellness visit. They can order preventive screening based on your age and health history. Many preventive tests are covered at no cost, but your doctor decides which ones you need. Fasting tests like glucose or cholesterol screening work best if done in the morning.
Can I get my wellness visit and blood work on different days?
Yes. You can have your wellness visit one day and schedule blood work at a lab on another day. Some people prefer this because fasting blood tests require an empty stomach, and the wellness visit itself does not require fasting. Ask your doctor which approach works best for you.
How long does it take to get blood work results?
Most routine blood tests take 1 to 3 business days. Your doctor's office will contact you with results, or you may be able to view them online through your patient portal. Ask your doctor's office how you will receive results and when to expect them.
