Prospect 811 runs on the data CMS publishes about who bills Medicare for what: 535 million billing, prescribing, and industry-payment records going back to 2013. Procedures, durable equipment, Part D prescriptions, hospital and post-acute case volumes, and manufacturer payments, all 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, and the hospital files tell you where the cases happen. The rest tells you who they are, where they are, and who they're part of.
Twenty itemized above. Ten more counted here. Thirty in total. The ten come as five groups, each with what it puts in a rep's hands:
The ten stay off the table on purpose: by the time you've copied this list, it's longer.
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, Part D, and the hospital files), 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, any prescription line with 10 or fewer claims, and any hospital cell under 11 cases, to protect patient privacy. Very low-volume activity simply won't appear, by design.
Part B, DME, Part D, and the hospital files currently run through 2024, matching what CMS has released. The lag is deliberate: CMS holds each file until every claim reaches final action, with all adjustments resolved. What you see is the settled record, not an estimate. 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 Medicare Inpatient & Outpatient Hospital files, the CMS Open Payments (Sunshine Act) files, the NPPES NPI registry, and CMS enrollment, affiliation, and drug reference data. Prospect 811 organizes and connects these sources; it doesn't add to or alter the underlying numbers. Not affiliated with or endorsed by CMS.
