Connecticut ambulatory surgical centers — FAQ

How many ambulatory surgical centers are Medicare-certified in Connecticut?
52 Medicare-certified ambulatory surgical centers operate in Connecticut as of the CMS Care Compare ASC Quality snapshot (2026-05-07). Every facility carries a National Provider Identifier — ASCs are the only Care Compare facility type with a 100% deterministic NPI bridge.
What ASC quality measures does Connecticut report?
CMS publishes ASC-1 through ASC-12. This page aggregates the state mean for the per-facility rate measures that have at least one reporting facility in Connecticut, plus the ASC-12 colonoscopy follow-up performance category. Measures are CMS-published rates: lower is better for adverse-event measures (burns, transfers, wrong-site events, readmissions, cataract complications) and higher is better for appropriate prophylactic antibiotic use.
Why are some facilities missing a quality rate?
CMS suppresses a measure when a facility falls below the minimum case volume for that measure in the reporting window. Suppressed facilities are excluded from each state mean rather than counted as zero, so the averages reflect only facilities CMS actually scored.
Where does this ASC data come from and how current is it?
The displayed fields come from the CMS Care Compare Ambulatory Surgical Center Quality file, source-modified 2025-12-16. Record-level provenance can be null; cross-check a consequential facility record at Medicare.gov.

Built on the authoritative federal record

The primary sources, named on every page.

These are the federal agencies whose public datasets Fonteum ingests and attributes — the issuing authorities, not customers or partners. Every figure on the site links back to one of them.

Reproducible by design

Published figures name their source and date.

Source and date

Published research identifies its government file and observation date. Source-file SHA-256 coverage is disclosed separately; facts do not currently link deterministically to signatures.

Reproducible SQL

Each study ships the exact query behind its figures, run against the same dated copy of the federal file we used. Re-run it yourself.

Daily observations

The platform records table row counts daily. Those observations detect local drift; they do not imply that an upstream publisher released or Fonteum ingested new data that day.
