Where these numbers come from. Everything on this page is computed from CMS's public Medicare Provider Utilization & Payment data for 2024, 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. One service is one specimen exam or stain as billed to Medicare. 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.

This is one code family, one state, one year.

Prospect 811 searches all 535 million Medicare billing records on any code you sell, maps your exact territory, and hands you the phone numbers. $79/month, no contract, 14-day refund.
