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.
Identity backbone for ESRD facilities (POS QIES doesn't cover dialysis). Drives the brand-hub `/care-compare/dialysis` module. Chain-ownership concentration (~90% chain-owned) is 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 a follow-on wave.
- 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).
