Medicare Annual Wellness Visit Billing 2026

2026 Rates, Required Elements and Same-Day E/M

By Yagnesh Dave  ·  June 2026  ·  9 min read

The Medicare Annual Wellness Visit (AWV) is one of the most consistently underused preventive services in primary care. It carries no patient cost-sharing, pays $174.35 for the initial visit (G0438) and $137.61 for subsequent visits (G0439) at 2026 Medicare non-facility rates, and requires no physical exam. The barriers are almost always billing and documentation confusion, not clinical capacity. This guide explains exactly how to bill it correctly.

AWV vs. Physical Exam: Understanding the Difference

The single biggest misconception about the AWV is that it replaces or duplicates the Annual Physical. They're completely different services:

A Medicare patient can receive both an AWV and a separately billed E&M visit on the same date, as long as a distinct problem was addressed and Modifier 25 is appended to the E&M code. This is a commonly missed billing opportunity.

AWV Reimbursement 2026: G0438 and G0439 Rates

At 2026 Medicare national non-facility rates, the initial annual wellness visit (G0438) pays $174.35 and each subsequent visit (G0439) pays $137.61. The patient owes no deductible or coinsurance, and locality adjusts the payment. A separate E/M can be added with modifier 25 on the E/M.

G0438 is the initial annual wellness visit, billed once for a patient who is past the first 12 months of Part B and hasn't had an AWV or IPPE in that window. G0439 is the subsequent visit, billed once every 12 months after a paid AWV.

The Two AWV Codes at a Glance

What the AWV Must Include: Required Components

CMS has defined specific components that must be completed and documented for each AWV. Missing even one can result in a denial on post-payment audit. The required elements differ slightly between G0438 and G0439.

Required for Both G0438 and G0439

• Health Risk Assessment (HRA): a patient-completed questionnaire covering self-reported health status, psychosocial risks, behavioral risks, and ADL limitations. This can be done via paper, kiosk, or patient portal before the visit.
• Medical and family history review, documented review and update of the patient's medical history, medications, and family history
• Biometric measurements: height, weight, BMI, blood pressure; establish baseline or update existing record
• Cognitive assessment: detection of any cognitive impairment using a validated tool (e.g., Mini-Cog, MMSE, or direct observation)
• Depression screening, using a standardized tool such as PHQ-2 or PHQ-9
• Functional ability and safety assessment, screening for fall risk, hearing impairment, home safety
• Personalized prevention plan: written 5–10 year prevention plan based on the patient's health status and risk factors, including recommended screenings and immunizations
• List of current providers and suppliers, establish or update the patient's care team list

Additional Required for G0438 (Initial Only)

• Review of potential risk factors for depression and other mood disorders
• Review of patient's current opioid prescriptions and any substance use
• Establishment of baseline measurements for future comparison

Revenue Opportunity: What an AWV Program Can Generate

This is an illustration built from CMS 2026 national non-facility rates, not a benchmark; your visit mix, locality and completion rate will move it. As a rule of thumb, every 10 additional completed AWVs is worth about $1,376 at the subsequent rate and about $1,744 at the initial rate.

Billing the AWV with a Same-Day E&M Visit

This is the most important same-day billing rule to get right. If the patient presents for their AWV and also has a new or established problem that requires evaluation and management (a new medication side effect, a lab result to review, a new complaint) you can bill both the AWV and an E&M on the same day.

The requirements:

• Append Modifier 25 to the E&M code (not to the AWV code)
• The E&M documentation must be separate from the AWV documentation; it must reflect a distinct chief complaint, assessment, and plan
• The E&M must meet the level-of-service criteria independently (medical decision-making or time-based documentation)

AWV and Other Same-Day Preventive Services

Certain preventive services can be billed on the same date as the AWV without any modifier, because they're not considered bundled into the AWV payment:

• Depression screening (G0444), Medicare treats annual depression screening as its own benefit with its own once-every-12-months limit, so check your MAC's policy before you report it alongside an AWV, since the AWV already includes a depression-risk review
• Advance Care Planning (99497), if the provider discusses advance directives during or after the AWV, ACP can be billed as a separate service when it meets the time threshold (at least 30 minutes)
• Chronic Care Management (G0511/99490): CCM is billed monthly, not per visit, so there's no conflict with a same-day AWV
• Immunizations (90xxx): vaccine administration codes are always separately billable

Who Can Perform and Bill the AWV

The AWV can be furnished by a variety of clinical staff, not just the physician:

• Physicians (MD, DO)
• Nurse practitioners (NP)
• Physician assistants (PA)
• Clinical nurse specialists (CNS)
• Medical professionals (RN, LPN, or clinical staff) under direct supervision, for the health risk assessment and data-gathering portion; the physician or NPP must review and sign

Many practices use a nurse-led AWV model: a medical assistant or RN completes the HRA, biometrics, and screeners in a 20-minute pre-visit workflow; the physician reviews and completes the prevention plan in 10 minutes. This dramatically increases throughput without consuming physician time.

Documentation Checklist for a Clean AWV Claim

Use this checklist before billing every AWV encounter:

• ☑ HRA completed by the patient and filed in the medical record
• ☑ Height, weight, BMI, and blood pressure documented with values
• ☑ Cognitive screening tool documented (name the tool, result, and interpretation)
• ☑ Depression screening documented (PHQ-2 or PHQ-9 score recorded)
• ☑ Fall risk assessment documented
• ☑ Current medications list reviewed and updated
• ☑ Medical and family history reviewed and updated
• ☑ Personalized prevention plan generated and given to patient
• ☑ Preventive service schedule documented (list of recommended screenings with due dates)
• ☑ Provider/supplier list established or updated
• ☑ Correct G-code selected (G0438 initial vs. G0439 subsequent)
• ☑ Diagnosis code: Z00.00 (encounter for general adult medical examination, no abnormal findings) or Z00.01 (with abnormal findings)

Top AWV Denial Reasons

1. Frequency Violation

Billing a second AWV too soon is the most common denial. Medicare's claims system rejects an AWV when another one was paid in the previous 12 months (CMS Claims Processing Manual, Chapter 18, section 140.6), so the window is rolling, not a calendar year. A patient who had a G0439 on December 15, 2025 isn't eligible for another one on January 1, 2026. Always query eligibility before scheduling.

2. G0438 vs. G0439 Mismatch

If Medicare's records show a prior AWV (from any provider) and you bill G0438, it will deny. The eligibility check must be done at the payer level, not just in your own EHR.

3. Missing HRA Documentation

If the Health Risk Assessment is not in the medical record or is documented only as "completed" without the actual responses or a reference to a completed form, post-payment audit will recoup the payment. Keep the HRA on file.

4. Bundling AWV with Welcome to Medicare Visit

G0402 (Welcome to Medicare/IPPE) and G0438 (Initial AWV) can't be billed within 12 months of each other. If a patient received their G0402 recently, you can't bill G0438 until 12 months have passed.

AWV Audit Exposure: Required Elements and Frequency

The AWV has a list of required components, and the article notes that missing even one can lead to a denial on post-payment audit. Reviewers check that the health risk assessment, the review of medical and family history, the functional and cognitive screening, and the personalized prevention plan were each completed and documented. A note that reads like a regular preventive exam doesn't support the code.

Frequency is the other test. G0438 is a one-time benefit, and G0439 can't be billed when another AWV was paid in the previous 12 months. Check eligibility before you schedule, because Medicare will deny an ineligible claim, and a practice that repeatedly bills early is easy to spot. Contractors can review three years of claims, so a template that skips a required element affects every patient it was used for.

Frequently Asked Questions About the Annual Wellness Visit

How much does Medicare pay for the annual wellness visit in 2026?

At 2026 Medicare national non-facility rates, the initial annual wellness visit (G0438) pays $174.35 and each subsequent visit (G0439) pays $137.61. The patient owes no deductible or coinsurance, and locality adjusts the payment. A separate E/M can be added with modifier 25 on the E/M.

What is the difference between G0438 and G0439?

G0438 is the initial annual wellness visit, billed once for a patient who is past the first 12 months of Part B and hasn't had an AWV or IPPE in that window. G0439 is the subsequent visit, billed once every 12 months after a paid AWV.

Can you bill an E/M on the same day as the AWV?

Yes, when the E/M addresses a separate problem and is documented separately. Put modifier 25 on the E/M code, not on the AWV. The E/M has to support its level on its own through medical decision making or time.

What's the difference between G0438 and G0439?

G0438 is the initial AWV for a patient enrolled in Part B for at least 12 months who hasn't had a previous AWV. G0439 is the subsequent visit. The required elements differ slightly between the two, as the article lists.

Can you bill an E/M on the same day as an AWV?

Yes, when the patient has a separate problem that requires its own evaluation and management and the note documents it. The article calls this the most important same-day billing rule to get right.

Is the AWV the same as a physical exam?

No. The article says it requires no physical exam and doesn't replace an annual physical. It builds a personalized prevention plan, and it carries no patient cost-sharing.

Building a Proactive AWV Outreach Program

The practices that capture the most AWV revenue don't wait for patients to schedule; they run proactive outreach. A simple framework:

1. Monthly eligibility pull: Run a report of all Medicare patients who have not had an AWV in the current calendar year
2. Automated outreach: Send a text/email to eligible patients with a direct scheduling link
3. At every visit: Train front desk to check AWV eligibility for any Medicare patient checking in and offer same-day completion if the schedule allows
4. Nurse-led workflow: Designate 30-minute AWV-specific appointment slots where an RN or MA completes the screening elements, freeing physician time for the plan and documentation

Practices using this model typically reach 55–70% AWV completion rates within 6 months. The billing is straightforward once the workflow is consistent.
