CDC BRFSS prevalence is survey data covering all-payer adults 18 and older; Nevvi utilization counts Medicare fee-for-service only, largely 65 and older. The two appear side by side as context — Nevvi never combines them into a score, rating, or ranking. See Methods.
- Market sizeThe volume of this code in the market for the year: an all-Medicare estimate scaled from the observed fee-for-service count where one can be drawn, otherwise the narrower count the row names. ~187,588 all-Medicare services · est. (90,946 observed FFS).
- Who bills itHow many named billing organizations and how many individual clinicians billed this code nationally. Billing that falls under CMS's 11-beneficiary disclosure floor is absent from the published record, so the smallest billers are missing. 25 billing groups and 104 clinicians bill G0422 nationally (at the ≥11-beneficiary disclosure floor).
- GrowthHow this code's volume changed year over year and over five years. A change between two years of the record, never a projection of what comes next. Up 38.3% year over year; +407.2% over five years (2020 → 2024). The five-year base year, 2020, is the pandemic year.
- Market structureThe share of this code's attributed national volume held by its five largest billing groups. The banded concentration read — fragmented through highly concentrated — is stated per state market, not nationally. The top five groups hold 68.0% of attributed national volume.
- Medicare paymentWhat Medicare paid for this code in the market over the year, and the payment per service. Observed fee-for-service payments only: Medicare Advantage is paid by capitation and is not counted.Medicare's payments for G0422 nationally in 2024, and the payment per service.

- Leading marketsThe state markets with the most volume for this code, and the share of all state-market volume they hold between them. Territories and billing that names no state sit outside that share. NV, CA, AR, and LA lead the state markets — together 50% of state-market volume.
