DMEPOS suppliers on federal exclusion lists
DMEPOS has historically been the highest-fraud category in Medicare. CMS imposed enrollment moratoria in multiple states (most recently Florida, March 2026). Cross-checking the active supplier directory against federal exclusion lists is a direct state and federal PI signal. **Result: 0 matches across 63,988 active DMEPOS suppliers** — the federal enrollment gate is working. Worth publishing as the comparison baseline against the H24, H25, H29, H30a, H30b non-zero findings.
Headline
0 of 63,988 active DMEPOS suppliers in the CMS Medicare DME, Devices & Supplies by Supplier file (DY 2023) appear on the active OIG LEIE ∪ SAM.gov exclusion list (8,619 excluded NPIs). This is the system working correctly: DMEPOS enrollment screens federally-excluded NPIs at the gate, which is what 42 CFR § 424.530(a)(2) and CMS DMEPOS Supplier Standard 11 require. Worth publishing as a reference point — when other federal program directories (NDH, see H24/H25; state Medicaid spending, see H29) show non-zero exposure, the DMEPOS zero is the comparison baseline.
0 / 64.0K = 0.00%
Null hypothesis
Zero NPIs in the current CMS DMEPOS Supplier Directory appear on the OIG LEIE or SAM.gov active exclusion lists.

Data source
CMS DMEPOS Supplier Directory (DY 2023, mup_dme_ry25_p05_v10_dy23_supr.csv) × `cms_npd.oig_leie` + `cms_npd.sam_exclusions`. See `analysis/claims_sources/dmepos.py`.
Notes
This is a national finding — DMEPOS supplier directory is itself the population, joined against the active LEIE ∪ SAM NPI set (8619 NPIs).
