Montana ambulatory surgical centers: 22 Medicare-certified, ASC quality measures with NPI bridge.
Per-facility ASC-1 through ASC-12 quality measures with deterministic NPI bridge (100.0% NPI coverage in Montana) — the only Care Compare facility type with a usable provider-identity join key.
Editorial note: Montana is a state where source-cited public-data coverage of ASC quality is materially thinner than national averages — Fonteum prioritizes full provenance + state context here.
ASC-12 performance breakdown — Montana
ASC-12 measures hospital-visit rate within 7 days of outpatient surgery. CMS-published performance categories on facilities meeting the volume threshold.
ASC-1 through ASC-11 quality measures — Montana state means
Each row is the mean CMS-published rate across Montanafacilities 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.

Montana ambulatory surgical centers — FAQ
- How many ambulatory surgical centers are Medicare-certified in Montana?
- 22 Medicare-certified ambulatory surgical centers operate in Montana 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 Montana 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 Montana, 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.
