Prospect 811 runs on the data CMS publishes about who bills Medicare for what — 427 million billing and prescribing records going back to 2013 — procedures, durable equipment, and Part D prescriptions — stitched together with the provider registry, group affiliations, enrollment files, patient-panel summaries, and FDA drug labels. Public data, all of it, in one place you can actually search.
The billing data tells you who's spending Medicare dollars on your codes. The rest tells you who they are, where they are, and who they're part of.
Part D prescriptions are the biggest single file — three hundred million rows on their own, with Part B right behind. Everything else exists to give those numbers a name and a place.
Every row is one provider, one code or drug, one year — with the dollars attached. This is what a search is actually reading.
Because the data goes this deep, a search can do more than name a provider. It can rank them by exactly the codes you sell, compare what they bill year over year, and roll it up to the group they belong to.
It's a powerful picture, but it's a specific one. Knowing the edges makes you sharper with it.
This is traditional Medicare — Part B, DME, and Part D — not commercial insurance or Medicare Advantage. For providers who serve Medicare patients, it's the clearest billing signal there is.
CMS withholds any provider-and-code line with fewer than 11 beneficiaries, and any prescription line with 10 or fewer claims, to protect patient privacy. Very low-volume activity simply won't appear — by design.
Part B and Part D currently run through 2024 and DME through 2023, matching what CMS has released. New years load in as CMS publishes them.
Built entirely from public CMS and HHS releases — Medicare Provider Utilization & Payment data (Part B, DME, and Part D prescriber files), the NPPES NPI registry, provider affiliation files, Medicare enrollment data, and openFDA drug labels. Prospect 811 organizes and connects these sources; it doesn't add to or alter the underlying numbers. Not affiliated with or endorsed by CMS.
Point four hundred million billing records at the products you sell and see what comes back.
