City totals are cut from the same public CMS data as everything above: Medicare fee-for-service only, after CMS's under-11-beneficiary suppression, dollars always est. Medicare paid. Where a city shows fewer than 3 providers, we show the totals and name no one. Naming is capped by design: up to 5 ranked providers above plus at most one leader per city here, and no one else on this page.

Where these numbers come from. Everything on this page is computed from CMS's public Medicare Provider Utilization & Payment data for 2023, the most recent year CMS has released. It covers traditional Medicare fee-for-service only (no commercial insurance, no Medicare Advantage). CMS suppresses any provider-and-code line with fewer than 11 beneficiaries before publishing, so low-volume billers don't appear at all. "Est. Medicare paid" is each billing line's average Medicare payment multiplied by its service count, summed. Collagen dressings bill per dressing unit and collagen wound fillers per gram, so one service is one unit or gram as billed. The providers named here are the ordering clinicians, not the supply companies that billed: these are the people to call, and the dollar figures are what Medicare paid to furnish what they ordered. Prospect 811 organizes public data; it doesn't add to or alter it. Not affiliated with or endorsed by CMS. Full detail on the data page.
