SAM aggregates HHS LEIE + OPM FEHBP debarment + other federal-agency actions. The OPM slice is net-new federal-screening signal beyond what LEIE alone surfaces.",

  "notes": "SAM source: sam.gov/data-services/Exclusions/Public V2 (V2_26120 extract). Total SAM rows: 167,262; with real-format NPI: 7,063 (4.2%); active + with NPI: 7,063. The 96% of SAM rows without a populated NPI are non-healthcare exclusions (OFAC sanctions, EPA contractor debarment, etc.) and are out of scope for this NPI-keyed match. The HHS-slice match overlaps substantially with the H24 LEIE finding by design \u2014 the same exclusion appears in both feeds. Each match is a data-quality flag, not a fraud determination \u2014 investigation, hearing rights, and reinstatement claims belong to the excluding agency. sam.gov/search/?index=ex is the authoritative source for any individual verification."
