Why Did I Get a Bill for My Annual Physical?

What the law requires for preventive care

Under the Affordable Care Act (ACA), most non-grandfathered health plans must cover a defined set of preventive services at zero cost-sharing — no copay, no deductible — when you use an in-network provider 1Ref 1U.S. Department of Health and Human Services (2024).Preventive Health Care Benefits — HealthCare.gov.ACA requirement that non-grandfathered health plans cover USPSTF-recommended preventive services at zero cost-sharing when provided by in-network providers. Annual wellness visits fall within this requirement. Grandfathered plans that existed before the ACA and have not significantly changed are not subject to this mandate; your plan's Summary of Benefits and Coverage (SBC) will say whether it is grandfathered 1Ref 1U.S. Department of Health and Human Services (2024).Preventive Health Care Benefits — HealthCare.gov.ACA requirement that non-grandfathered health plans cover USPSTF-recommended preventive services at zero cost-sharing when provided by in-network providers.

Why does a 'free' preventive visit generate a charge?

A few billing situations routinely catch patients off guard.

You brought up a symptom or problem. If you mentioned a new concern — knee pain, fatigue, a rash — the clinician may have addressed it as a separate evaluation and management (E&M) visit. Per AMA and insurer guidelines, if the problem requires additional clinical work beyond the preventive visit, it can be billed with a separate E&M code appended with Modifier 25 2Ref 2American Academy of Family Physicians (2022).Combining a Wellness Visit With a Problem-Oriented Visit: A Coding Guide.CPT coding for split preventive-plus-E&M visits, use of Modifier 25, documentation requirements, and patient notification best practices when problem-oriented billing is added to a preventive visit.

A chronic condition was managed. If the doctor adjusted medications or discussed lab results for an ongoing condition like diabetes or high blood pressure, that is disease management — not prevention. Insurers separate it.

A diagnostic test was ordered. Screenings that meet specific USPSTF guidelines (such as a colonoscopy at the recommended age for average-risk adults) are often covered fully as preventive. A test ordered to investigate a symptom is diagnostic and may carry cost-sharing.

The provider is out of network. Even for a preventive visit type, an out-of-network provider may bill differently.

A lab or ancillary service is not bundled. Some plans cover the face-to-face exam but not every associated service billed by a separate entity.

How do you read your bill to understand what happened?

Request an itemized bill from your provider's billing office — a line-by-line list of every service with its CPT code. Then pull your insurer's Explanation of Benefits (EOB), available by mail or through your insurer's member portal.

The EOB shows what was billed, what the insurer paid, what you owe, and a reason code for any non-payment. Compare the two documents.

Look for: - A preventive code (often in the 99381–99397 range) - An E&M code alongside it (often in the 99202–99215 range) with Modifier 25

If you see both, you were likely billed for a split visit — the preventive portion covered at no cost, and the problem-oriented portion charged to your cost-sharing 2Ref 2American Academy of Family Physicians (2022).Combining a Wellness Visit With a Problem-Oriented Visit: A Coding Guide.CPT coding for split preventive-plus-E&M visits, use of Modifier 25, documentation requirements, and patient notification best practices when problem-oriented billing is added to a preventive visit. This is a permitted billing practice, not automatically a billing error.

When should you appeal — and how?

If you believe the visit was coded incorrectly — for example, you did not bring up any new problems and the charge does not seem warranted — you can appeal.

Step 1. Call your provider's billing office. Ask them to explain each charge and review the codes. Billing errors are sometimes caught and corrected at this step.

Step 2. If you still believe the coding is wrong, ask your insurer to formally review the claim. Every insurer has an appeals process; the EOB includes instructions.

Step 3. If your appeal is denied and you remain concerned, your state insurance commissioner's office can help.

Keep notes of every call: date, representative name, and what was said.

How can you avoid this happening at future visits?

At the start of your next annual visit, tell the clinician explicitly: "I would like this to remain a routine preventive appointment." If you have additional health concerns, ask whether it makes sense to schedule a separate visit for them — so the preventive billing stays clean.

The AMA recommends that physicians proactively inform patients before addressing additional problems at a preventive visit that separate cost-sharing may apply 2Ref 2American Academy of Family Physicians (2022).Combining a Wellness Visit With a Problem-Oriented Visit: A Coding Guide.CPT coding for split preventive-plus-E&M visits, use of Modifier 25, documentation requirements, and patient notification best practices when problem-oriented billing is added to a preventive visit. You can ask this question before the visit starts.
