What is HCPCS G0438 used for?

G0438 is the initial Medicare Annual Wellness Visit (AWV), a once-per-lifetime prevention-planning visit for beneficiaries who have had Part B for more than 12 months and have not previously had an AWV. It builds the health risk assessment and the written personalized prevention plan that subsequent wellness visits update.

The visit is structured rather than a physical exam. It includes a health risk assessment, a review of medical and family history, current providers and medications, vital signs, cognitive screening, depression and functional screening, and creation of the written personalized prevention plan and screening schedule. Eligibility is tight: the patient must have had Part B for more than 12 months, must not have had a prior AWV, and cannot be within 12 months of a G0402 IPPE.

How much does G0438 pay in 2026?

G0438 carries 5.22 total RVUs in both settings. At the 2026 conversion factor of $33.4009 that is about $174.35, facility and non-facility alike, with no patient cost-sharing as a covered preventive service. It pays more than the subsequent AWV G0439 because the prevention plan is being created rather than updated. See your locality-adjusted rate on the Medicare fee calculator.

Frequency rules and the AWV family

The wellness codes must be sequenced correctly, because each has its own frequency window and billing one out of order draws a clean denial:

CodeVisitFrequency
G0402IPPEOnce, first 12 months of Part B
G0438Initial AWVOnce per lifetime
G0439Subsequent AWVEvery 12 months thereafter
Working-biller angle: the classic denial is billing G0438 a second time, it is once-per-lifetime, so any prior AWV means the patient needs G0439 instead. Also avoid billing G0438 within 12 months of a G0402. When a distinct, medically necessary problem is addressed at the same encounter, add a problem E/M (99202-99215) with modifier 25 so the separate work is captured rather than folded into the wellness visit. Check the patient's AWV history before choosing the code.
Check your jurisdiction: Coverage, frequency, and documentation rules here reflect national guidance. Your MAC may enforce a different Local Coverage Determination — confirm your jurisdiction's active LCD before billing. Dollar amounts shown are national baselines; your locality's GPCI-adjusted rate will differ.
