CMS Care Compare — ASC

CMS Care Compare — ASC Quality Measures (Facility)

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

Live
Source:CMS Care Compare — ASC·Snapshot May 2026Open official source ↗

Per-facility ASC quality measures (ASC-1 through ASC-12) submitted via the ASC Quality Reporting Program for ~5,611 Medicare-certified ambulatory surgical centers. Identity + NPI + state + per-measure rates and footnotes. **NPI IS PRESENT** (100% coverage) — the only Care Compare dataset that publishes NPI directly on the agency-level table.

What Fonteum uses it for

How this source shows up on Fonteum.

Sprint 1 LOCKED-7 #9: identity backbone for ASC CCNs (POS QIES coverage incomplete). Deterministic NPI bridge (no NPPES fuzzy match needed) — match-confidence improvement vs other Care Compare datasets. Drives the brand-hub `/care-compare/asc` module per Sprint 1 master spec Page 5. ASC-12 (7-day risk-standardized hospital visit rate) is the headline quality measure.

What this source does NOT mean

ASCs do NOT have a CMS-published overall star rating (unlike NH / HH / Dialysis). Quality is per-measure (ASC-1 through ASC-12); Fonteum does not manufacture composite scores. Suppression for <25 cases applies.

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.

  • Suppression for <25 cases — render `<DataAvailabilityState>` with explicit reason.
  • SDOH measure newly required from 2025 reporting period — limited baseline comparison data for the first 2 years.
  • No CMS-published overall star rating; quality is per-measure.
  • `facility_id` is the source field name for CCN — ingestion normalizes to `ccn` for downstream consistency.
  • Multi-year rows in source dataset; ingestion filters to most recent year and dedupes.
  • Non-state jurisdictions present (PR, GU, VI, MP, AS).

Sample provenance

What a single field looks like in the graph.

A worked example. Every field surfaced from this source carries this shape of provenance line — source · last checked · display rule · confidence (when applicable).

Field

NPI presence + CCN format (snapshot 2026-05-07)

Sample value

5,611 facilities; reporting year 2024; 100% NPI presence; 100% 10-char CCN conformance

Provenance line

Source: CMS Care Compare · ASC Quality Measures - Facility (4jcv-atw7) · Reporting Year 2024 · Snapshot 2026-05-07 · Display rule: per-facility ASC-1 through ASC-12 + ASC-12 performance category render on /care-compare/asc module + per-facility pages

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.
