CMS Care Compare — DialysisCMS Care Compare — Dialysis Facility
U.S. Centers for Medicare and Medicaid Services · Tier-1 · research-only (never on individual profiles)
Agency-level identity + 5-star quality rating + ownership + chain affiliation + service offerings (in-center hemodialysis, peritoneal dialysis, home hemodialysis training) for ~7,557 Medicare-certified ESRD facilities. Underlying signal includes ESRD QIP measures and ICH CAHPS.
How this source shows up on Fonteum.
Sprint 1 LOCKED-7 #8: identity backbone for ESRD facilities (POS QIES doesn't cover dialysis). Drives the brand-hub `/care-compare/dialysis` module per Sprint 1 master spec Page 4. Chain-ownership concentration (~90% chain-owned) is doctrinally relevant journalism material.
What this source does NOT mean
Star rating reflects the CMS-published 5-star dialysis rating; Fonteum does not independently rate, score, or rank facilities. Suppression for <11 patients in the measure period applies.
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.
Renders on profile
18 fieldsWhat we can’t infer from this source.
- Suppression for <11 patients in measure period — render `<DataAvailabilityState>` with explicit reason rather than implying low quality.
- ICH CAHPS (patient-experience scores) live in a separate twice-annual dataset; deferred to §sprint1-dialysis-quality.
- 5-star rating is CMS-published; Fonteum does not independently score.
- Chain ownership is unusually concentrated (~90%); flag explicitly as journalism material.
- Non-state jurisdictions present (PR, GU, VI, MP, AS).

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.
