Each row is the mean CMS-published rate across Arizonafacilities that meet the measure’s reporting threshold. Lower is better for adverse-event measures; higher is better for the prophylactic-antibiotic process measure. Facilities CMS suppressed for low case volume are excluded from the mean, not counted as zero.

Arizona ambulatory surgical centers — FAQ

How many ambulatory surgical centers are Medicare-certified in Arizona?
204 Medicare-certified ambulatory surgical centers operate in Arizona 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 Arizona 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 Arizona, 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.

Integrated, with-data, and fresh-observation counts are separate. No platform-wide source-completeness count is published. Completeness is source-specific and must be evaluated against the named source's expected scope. State coverage is a separate jurisdiction measure.

Source authority is record-specific

Use the issuer named on the record.

Fonteum spans federal, state, and global public publishers. A source page or returned record identifies its issuer and dataset where that metadata is available. A platform registry count does not assign every page to one authority or establish loaded, fresh, or complete coverage.

Reproducible by design

Inspect the evidence each published figure actually supplies.

Source and date

Research pages expose the named public file and observation date where those fields are available. Source-file SHA-256 coverage is separate; facts do not currently link deterministically to signatures.

Available derivation

Studies with a retained release and committed derivation link the SQL or method used. Other studies state the evidence and reproduction limits they actually have.

Daily observations

Dated table row-count observations can detect local drift. They do not imply that an upstream publisher released or Fonteum ingested new data that day.
