CMS SNF All Owners

CMS SNF All Owners (PE / REIT / Chain Layer)

U.S. Centers for Medicare and Medicaid Services · Tier-1 · research-only (never on individual profiles)

Research-only
Source:CMS SNF All Owners·Snapshot May 2026Open official source ↗

Per-facility ownership disclosures derived from PECOS. Released November 2024 with new fields for PE/REIT classification + Additional Disclosable Parties (ADPs) under the November 17, 2023 Final Rule on Ownership Transparency (88 Fed. Reg. 80141). The 82.40% top-10-chain ownership-percentage gap is the central caveat (Chen/Grabowski/Konetzka, Health Affairs March 2024).

What Fonteum uses it for

How this source shows up on Fonteum.

Sprint 1 LOCKED-7 #5. Drives the brand-hub `/ownership` surface per master spec Page 8. Direct backbone for the published flagship study at /research/private-equity-nursing-home-ownership-analysis. Fonteum surfaces missingness via DataAvailabilityState: OWNERSHIP_PCT_MISSING — the gap is the data product.

What this source does NOT mean

Not a complete ownership picture. 82.40% of top-10-chain owners and 55.21% of all owners have missing ownership-percentage values. PE/REIT flags are voluntary and incomplete. Independent estimates put true PE ownership at ~13% vs. CMS's ~5% (PESP April 2025).

Fields used

Per-field display contract.

Every field below has a `display_allowed` flag in the §94 provenance schema. Write-locked fields are captured to provenance for audit but never rendered on profile pages.

Limitations

What we can’t infer from this source.

  • Ownership percentages missing for 82.40% of top-10-chain owners + 55.21% of all U.S. facility owners (Chen/Grabowski/Konetzka, Health Affairs March 2024).
  • PE/REIT flags reflect voluntary CMS self-reporting; many facilities have not filed under the December 2025 revalidation suspension.
  • Independent and CMS-derived PE-ownership estimates differ ~2.6× (PESP 13% vs. GAO 5%).
  • 5% disclosure threshold creates structural undercounting for layered LLC ownership cascades.
  • Fonteum does not fabricate, interpolate, or estimate missing ownership percentages.

Compliance posture

We don’t sell ranking and don’t accept payment to move a provider up the list. For final hire decisions, verify licensing, insurance, and references directly with the applicable licensing or credentialing body.

No bulk-licensing source family is currently ingested for this vertical. Hire-time checking still routes through the body named above.
