Unified provider exclusion lists — OIG LEIE + SAM + state Medicaid

RosterProof unifies the federal OIG LEIE, the full SAM.gov exclusions extract, and state Medicaid exclusion lists into a single dataset: collected continuously, normalized into one schema, tracked with full change history, and resolved to NPIs with transparent confidence tiers and provenance on every derived fact. Delivered as native tables on the Snowflake Marketplace, so exclusion screening becomes a simple join in your own warehouse — no scrapers to babysit, no PDFs to retype, no blind spots between the federal list and the states.

WHY IT MATTERS

Screening only the federal list misses half the risk

States exclude providers for reasons that never propagate to the federal LEIE — and when they do propagate, it happens with months of lag. The exposure is concrete: payments involving excluded parties risk overpayment recoupment and Civil Monetary Penalties, and under ACA §6501 an exclusion in one state's Medicaid program is grounds for termination in every other state. RosterProof closes that gap for providers and vendors — billing companies, DME suppliers, staffing agencies appear on these lists as entities — with every record carrying its source, jurisdiction, exclusion window, and an NPI match with stated confidence, so a compliance analyst can defend every hit without asking anyone.

Every format states publish. One schema you query.

We normalize all of it into a single canonical schema, so your screening query never cares how a state chose to publish.

FROM THE DATA

Even the exclusions that reach the federal list arrive five months late

State exclusions that eventually make it to the LEIE take a median 156 days to get there — a quarter take more than fifteen months, and half never arrive at all. That, the specialty risk map, the serial-excludee window, and more: what the data says →

How matching works: four tiers, strongest first

Every match carries its tier, evidence, and confidence. Unresolved records stay honestly unresolved.
