A billed "service" on this code is one 1 mg unit, not one patient visit — that's why the service counts below run high.

Where these numbers come from. Rates are CMS's own public fee-schedule files — the Physician Fee Schedule, Clinical Laboratory Fee Schedule, ASP drug pricing, DMEPOS, and the OPPS/ASC addenda — each labeled with its file year on this page; national amounts are shown before geographic adjustment. Codes with no separate rate render the fee schedule's own status in words, never a fake $0. Utilization comes from CMS's public Medicare Provider Utilization & Payment data for 2024, the most recent year released. It covers traditional Medicare fee-for-service only (no commercial insurance, no Medicare Advantage), and 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 times its service count, summed — actual per-claim payment varies by setting and modifiers. For drug and supply codes, a "service" is a billed unit (a milligram, a milliliter, a square centimeter), not a patient visit. Code descriptions are CMS's own, from the utilization files. 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.
