Pricing file2026 Q3 Average Sales Price (ASP)

A billed "service" on this code is one 10 mg unit, not one patient visit — that's why the service counts below run high.

What Medicare actually paid per service in 2024, on average: $24.57 (observed payment across all settings and modifiers — not a fee-schedule rate).

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.

One code, one year, top 5. The app has all of it.

Prospect 811 answers "what is this code, what does it pay, and who bills it?" for every billable code — then filters the answer to your exact territory, with phone numbers. $79/month, no contract, 14-day refund.
