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-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?
All columns trace to the CMS Care Compare Ambulatory Surgical Center Quality dataset (PDC 4jcv-atw7), source-modified 2025-12-16. Fonteum redistributes the public-domain CMS file without alteration and links every row to its provenance record; cross-check any facility at Medicare.gov.
