CMS Care Compare — HHCMS Care Compare — Home Health Care Agencies
U.S. Centers for Medicare and Medicaid Services · Tier-1 · research-only (never on individual profiles)
The agency-level wide table for ~12,400 Medicare-certified Home Health Agencies. Identity (CCN, name, address, ownership) plus headline 'Quality of Patient Care' star rating per agency. Quality-of-patient-care star ratings are computed by CMS from OASIS-derived process and outcome measures. NPI is not in this dataset; the cross-source join engine bridges via NPPES Type 2 fuzzy match.
How this source shows up on Fonteum.
Sprint 1 LOCKED-7 #2: identity backbone for Home Health Agencies (POS QIES does not cover HH). Drives the brand-hub `/care-compare/home-health` module per Sprint 1 master spec Page 2. State-level rollups + per-agency pages ship in follow-on §sprint1-pdc-a-pages waves.
What this source does NOT mean
This is not a directory of individual home-health workers — agencies, not aides. Star rating reflects the CMS-published Quality of Patient Care measure; Fonteum does not independently rate, score, or rank agencies.
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.

17 fieldsWhat we can’t infer from this source.
- CAHPS-style patient experience scores live in the separate HHCAHPS datasets (ccn4-8vby etc.); this snapshot does not include them. Suppression for <40 surveys still applies on those datasets per CMS methodology.
- Newly certified agencies have no Quality of Patient Care rating; render `<DataAvailabilityState>` with the explicit reason rather than implying low quality.
- Claims-based measures inherent ~12-month lag.
- Non-Medicare HHAs are excluded by definition.

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.
