Payer notes
Medicare covers G0439 with no patient cost share when billed as a stand-alone AWV. Medicare Advantage plans generally follow Medicare rules but some MA plans use proprietary G-codes for AWV equivalents; verify with each MA plan. Commercial payers do not pay G0439 (Medicare-only); commercial preventive visits use 99396 or 99397 for established patients (or 99386 or 99387 for new patients). Some MA plans pay incentives to providers who complete AWVs at high rates; check your value-based contracts. The 1.92 wRVU plus the same-day add-on stack (G0444, G0537, 99497, G0136) makes AWV-day workflow one of the highest-yield encounters in primary care.
