What CPT G0439 actually is
Annual wellness visit, subsequent (CPT G0439). This code falls in the "Preventive E/M" service family. Medicare's national-average non-facility allowed amount is the federally-set baseline; commercial insurance and hospital cash-pay rates often run multiples of this number for the same code, depending on the facility and contract.
The number above is one piece of context. The other two benchmarks worth knowing:
Hospital cash-pay rate
Federally required to be published by every US hospital under 45 CFR §180.50 (the Hospital Price Transparency rule). The hospital’s own machine-readable file is the authoritative source. Same code; rates vary widely by facility.
Insurance-negotiated rate
Whatever your specific insurance plan and the specific facility have contracted for the same code. Visible on your Explanation of Benefits (EOB) after the claim posts.
Medicare allowed amount (this page)
$141 for code G0439, set in federal law and updated annually by CMS. Used as the floor benchmark in most bill-review work.
Where CPT G0439 commonly shows up on a bill
Common patterns to look at when reviewing this code:
- 01.Preventive services and vaccines billed to the patient when the Affordable Care Act requires them to be $0 cost-share for in-network preventive care.
- 02.Vaccine administration billed without the corresponding vaccine product code, or vice versa.
These patterns are documented in CMS billing guidance, the National Correct Coding Initiative (NCCI) edits, and Office of Inspector General audit reports. None of them are accusations about any specific bill or facility — they’re the checks that exist because the patterns themselves exist.

P.S. If you’re holding a bill with code G0439on it right now, the fastest path is to run it through the audit — it takes just a few minutes and shows the exact gap between what was charged and the $141 benchmark above. Start the audit →
P.P.S. If the bill came from a non-profit hospital, federal law (ACA §501(r)) requires them to offer charity care to patients below specific income thresholds. We auto-check 501(c)(3) status against the IRS Publication 78 database and draft the application letter when applicable.
P.P.P.S. The $141number above is a benchmark, not a verdict. The right question on any specific bill is whether the documentation in your medical record supports the code that was billed — that’s what every bill-review process ultimately comes down to.
