Annual Wellness Visit CPT Code
📘 2. What Is an Annual Wellness Visit (AWV)?
The Annual Wellness Visit (AWV) is a Medicare-covered preventive service aimed at developing or updating a Personalized Prevention Plan for the patient. Unlike a typical physical exam, an AWV focuses on health risk assessments, screenings, and future health planning rather than hands-on physical diagnosis.
📌 Key Points:
-
Introduced by the Affordable Care Act in 2011
-
Covered annually for Medicare Part B beneficiaries
-
Focused on prevention, lifestyle counseling, and care coordination
📝 Major Components of an AWV:
-
Review of medical/family history
-
Measurement of vital signs (height, weight, BMI, blood pressure)
-
Cognitive impairment detection
-
Depression screening
-
Establishing/updating a list of current providers and medications
-
Personalized Health Advice and referrals
-
Advance care planning (optional)
AWVs are not subject to deductibles or coinsurance, making them highly valuable for both providers and patients.
📎 3. Purpose and Benefits of Annual Wellness Visits
From a public health standpoint, AWVs are an important tool for early intervention and chronic disease prevention. For providers, it represents an opportunity to engage patients proactively, build long-term relationships, and align with quality care metrics.
🎯 Primary Goals:
-
Prevent costly emergency room visits through proactive care
-
Identify undiagnosed issues such as cognitive decline
-
Encourage screenings and vaccinations
-
Update care plans based on current risk factors
-
Coordinate care among multiple specialists
📌 4. Key CPT Codes for Annual Wellness Visits
Let’s break down the most important HCPCS (Healthcare Common Procedure Coding System) Level II codes that represent AWVs:
| CPT/HCPCS Code | Description | When to Use |
|---|---|---|
| G0402 | Initial Preventive Physical Examination (IPPE) | One-time use within 12 months of Part B enrollment |
| G0438 | Initial Annual Wellness Visit (AWV) | First AWV after IPPE or if IPPE not done |
| G0439 | Subsequent Annual Wellness Visit | Once per year following the initial AWV |
These codes are specific to Medicare and are often misunderstood or improperly billed, which leads to denials or payment delays.
