The Medicare Annual Wellness Visit covers preventive planning but not diagnosis or treatment -- and if your doctor addresses a problem during the visit, you will owe extra.
The Medicare Annual Wellness Visit covers preventive planning but not diagnosis or treatment -- and if your doctor addresses a problem during the visit, you will owe extra.
The Medicare Annual Wellness Visit is free. No copay, no deductible, no coinsurance. But "free" has a boundary, and that boundary is narrower than most beneficiaries expect. The AWV covers a defined set of preventive services -- a checklist, essentially -- and the moment your provider steps outside that checklist into anything resembling diagnosis or treatment, a separate billable visit begins. Often during the same appointment. Often without anyone saying so out loud.
Most people find out where the line is when the bill arrives. Few things in healthcare billing generate more confusion than a charge attached to a visit you were told would cost nothing.
Medicare splits care into three categories. Which category applies determines what you pay.
Screening (preventive): Looking for potential problems before symptoms appear. This is what the AWV covers. It is free.
Diagnostic: Investigating a specific symptom, complaint, or abnormal finding. Not part of the AWV. You pay your Part B cost-sharing.
Treatment: Managing, treating, or prescribing for a condition. Not part of the AWV. You pay your Part B cost-sharing.
The same test can land in either column depending on why it was ordered. A screening mammogram is free under Medicare. A diagnostic mammogram ordered because your doctor felt a lump is subject to your deductible and coinsurance. Same machine, same images, same radiologist. Different billing code, different cost to you.
This principle governs everything that happens during your Annual Wellness Visit.
The complete list of what is included at no cost:
That is the full scope. Everything beyond it costs extra.
The AWV does not include a physical exam. Your provider will not listen to your heart and lungs, palpate your abdomen, check your reflexes, or perform any hands-on examination as part of the free visit. If your provider performs a physical exam during the same appointment, it gets billed as a separate office visit.
This catches people off guard. An "annual wellness visit" that does not include a physical exam feels incomplete. But that is how the benefit is structured.
No blood tests are included in the AWV. None. The following are all billed separately:
Medicare does cover certain screening blood tests as standalone preventive benefits (cardiovascular disease screening blood tests every five years, diabetes screening tests for those at risk), but these are billed under their own codes, not as part of the AWV.
A urine test is not part of the Annual Wellness Visit. If your provider orders one during the visit, it generates a separate charge.
An EKG is not included. One exception: if you are receiving your one-time Initial Preventive Physical Examination ("Welcome to Medicare" visit) during your first 12 months on Part B, Medicare covers a referral for a screening EKG. For all subsequent Annual Wellness Visits, no EKG is included.
No imaging of any kind -- X-rays, ultrasounds, CT scans, MRIs -- is part of the AWV. If your provider orders imaging during the visit, it is billed separately.
The AWV includes a review of your current medications. It does not cover writing new prescriptions or adjusting existing ones. If your provider changes a dosage or prescribes something new, that clinical decision-making gets billed as a separate evaluation and management service.
If you mention a new symptom during your AWV and your provider investigates or treats it, that portion of the visit is billed separately. Common triggers:
Each of these scenarios adds a separate billing code on top of the AWV.
The pattern is consistent:
This is not fraud. It is not improper billing. Your provider is required to code services accurately, and care beyond the scope of the AWV must be billed. The problem is that the transition from "free wellness visit" to "billable office visit" happens mid-conversation, without a pause, without a disclosure, and without the patient realizing the meter just started running. "Free" is doing a lot of heavy lifting in that waiting room brochure.
Here is the friction that nobody explains upfront. You are sitting across from your doctor during your wellness visit, and your shoulder has been bothering you for three weeks. You have two options:
Mention it now. Your provider examines your shoulder, maybe orders imaging, and you leave with a plan. You also leave with a bill you did not expect.
Say nothing and schedule a separate appointment. You protect the "free" status of your wellness visit. But now you need a second appointment -- another day off work, another trip, another copay that you knew about in advance.
Neither option is wrong. But one generates a surprise bill and the other generates a planned one. The difference is whether you chose the cost or the cost chose you.
You arrive for your Annual Wellness Visit. Your provider completes the health risk assessment, reviews your medications, conducts the depression screening and cognitive assessment, and begins working on your prevention plan. During the medication review, your provider notices your blood pressure is elevated and decides to adjust your medication. They also order blood work to check your cholesterol and kidney function.
What Medicare covers for free: The AWV components (risk assessment, medication review, screenings, prevention plan)
What you will be billed for: The office visit for managing your blood pressure (copay plus 20% coinsurance after deductible), the blood work (coinsurance after deductible), and potentially a separate charge for the medication management
Your Explanation of Benefits (EOB) will show multiple line items for what you experienced as a single appointment. Understanding the difference between an EOB and a bill matters here -- see our guide on EOB vs. medical bill.
You cannot always prevent additional charges, but you can reduce the surprises.
Tell the scheduling office explicitly: "I want only the Annual Wellness Visit. I do not want any additional services unless you tell me first that they will cost extra."
Ask your provider's office: "If the doctor finds something during the wellness visit, will they address it during this appointment or schedule a separate visit?"
Know your cost-sharing: Check your Part B deductible status (the 2026 Part B deductible is applied annually) and your coinsurance rate (typically 20% after the deductible).
Ask before they act. If your provider suggests any test, lab work, or examination beyond the standard AWV checklist, ask: "Is this part of the free wellness visit, or will it be billed separately?"
You can say no. If your provider wants to order blood work or address a health concern, you have every right to say, "I would like to schedule a separate appointment for that." This does not affect your AWV.
Watch for the transition. The moment your provider shifts from asking screening questions to examining, testing, or treating, the billing is likely changing. Common signals:
Review your Explanation of Benefits. When your EOB arrives from Medicare, check the billing codes. The AWV should be coded as G0438 (initial) or G0439 (subsequent). Any additional codes indicate services billed beyond the AWV.
Dispute billing errors. If you were charged for services you did not agree to or that were not explained as separate from the AWV, you have the right to dispute the bill. For guidance, see our billing disputes guide.
This deserves its own section because it catches so many Medicare beneficiaries off guard.
| Test | Screening Version (Free) | Diagnostic Version (You Pay) |
|---|---|---|
| Mammogram | Annual screening mammogram for women 40+ | Mammogram ordered because of a lump or symptom |
| Colonoscopy | Screening colonoscopy every 10 years (or 4 years high-risk) | Colonoscopy ordered because of bleeding or symptoms |
| Blood glucose | Screening for diabetes risk (twice per year if at risk) | Blood sugar test ordered to monitor diagnosed diabetes |
| PSA test | Annual screening PSA for men 50+ | PSA ordered because of urinary symptoms |
| Bone density | Screening DEXA scan every 2 years for women 65+ | DEXA scan ordered because of a fracture |
Same test, same machine, same results. The billing code and your cost depend entirely on the reason it was ordered. And if a screening test reveals an abnormality that requires a diagnostic follow-up, the follow-up is billed at diagnostic rates.
Medicare Part B covers many preventive services for free outside of the Annual Wellness Visit. These are separate benefits with their own eligibility rules:
Your provider may order some of these during the AWV as part of your prevention plan. When ordered as screening tests for eligible beneficiaries, they are covered at no cost. When the same tests are ordered for diagnostic purposes, you pay cost-sharing.
If you receive any bill after your Annual Wellness Visit, request an itemized bill from your provider's office. This document breaks down every charge, the billing code used, and the reason for the service. Compare it against your EOB from Medicare.
Look for:
If you find discrepancies, our guide on getting an itemized medical bill walks you through the process. For charges you believe are incorrect, see our medical billing disputes resources.
Medicare's billing structure around the Annual Wellness Visit is not designed to confuse people, but it reliably does -- and the burden of understanding the boundary between "free" and "billable" falls almost entirely on the patient. That gap between how the benefit is marketed and how it is actually billed deserves more transparency than it currently gets.
Your health records, including your billing records, belong to you. Staying informed about what Medicare covers and what it does not is one of the most practical ways to avoid surprise medical bills and get full value from your benefits.
