Annual Wellness Visits vs. Physicals: How to Bill Them Right in Primary Care

One of the most persistent front-desk and billing problems in primary care starts with a simple phrase: “I’m here for my annual physical.” For many commercially insured patients, that may describe a routine preventive exam. For Medicare patients, however, the Annual Wellness Visit (AWV) is a distinct preventive benefit with its own required elements and billing rules.

If scheduling, clinical documentation and billing teams use “physical,” “wellness visit” and “Medicare annual” interchangeably, practices can create patient confusion, denials and incorrect cost sharing.

An AWV is not the same as a routine physical

Medicare’s AWV is focused on health risk assessment, prevention planning, risk factors, functional and safety review, preventive screening schedules and personalized health advice. It is not simply a head-to-toe routine physical. CMS maintains the current requirements on its Annual Wellness Visit page.

Know the three Medicare preventive visit categories

• IPPE / “Welcome to Medicare” visit (G0402): generally available once during the first 12 months a beneficiary has Medicare Part B, subject to current CMS eligibility rules.
• Initial AWV (G0438): the first Annual Wellness Visit after eligibility requirements are met.
• Subsequent AWV (G0439): later Annual Wellness Visits, generally limited by the applicable 12-month frequency rule.

CMS states that G0438 is used for the first AWV and G0439 for subsequent AWVs, and that an AWV should not be billed within 12 months of an IPPE for the same patient. The CMS IPPE guidance and AWV coding guidance should be checked when designing scheduling edits.

The scheduling script matters

When a Medicare patient asks for a “physical,” staff should clarify what the patient wants and what benefit is available. A useful workflow verifies whether the patient is in the IPPE window, has had an initial AWV, or is eligible for a subsequent AWV. Staff should also explain that a separate medically necessary problem-oriented service may create cost sharing even if performed at the same appointment.

When can an E/M service be billed with an AWV?

CMS states that when a significant, separately identifiable and medically necessary E/M service is provided with the AWV, the additional E/M service may be separately payable when reported appropriately, including modifier 25 under Medicare guidance. Documentation should clearly distinguish the problem-oriented evaluation and management from the wellness components.

Do not add modifier 25 because the patient mentioned a chronic condition. The note should show the additional assessment and management that supports a separately reported E/M service.

Do not let the template become the service

AWV templates can help, but the medical record still needs to reflect the required elements actually completed. Common workflow failures include incomplete health risk assessments, missing or outdated provider lists, no documented screening schedule, absent functional/safety review, and copying last year’s plan without meaningful update.

2026 detail to know: optional physical activity and nutrition assessment

CMS’s 2026 AWV guidance includes an optional standardized physical activity and nutrition risk assessment using HCPCS G0136 under specified conditions. CMS also describes specific frequency and cost-sharing rules, including circumstances when modifier 33 is used with the AWV. Because this is an area where implementation details matter, use the current CMS AWV guidance rather than relying on an old coding cheat sheet.

Five common AWV billing mistakes

1. Billing G0438 when the patient already had an initial AWV and should be considered for G0439.
2. Billing an AWV too soon after the prior covered preventive visit.
3. Treating the AWV as a routine physical and failing to complete the required wellness elements.
4. Automatically adding a problem-oriented E/M code or modifier 25 without separate medical necessity and documentation.
5. Failing to verify Medicare Advantage plan-specific workflows, network rules or preventive benefits.

A better primary-care workflow

Build an eligibility flag into scheduling. Use separate documentation templates for IPPE, initial AWV, subsequent AWV and routine preventive exams. Train staff to explain the benefit in plain language. Before claim release, run an edit for prior AWV/IPPE history, code selection and same-day E/M documentation.
