New Hampshire ambulatory surgical centers — FAQ
- How many ambulatory surgical centers are Medicare-certified in New Hampshire?
- 27 Medicare-certified ambulatory surgical centers operate in New Hampshire 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 New Hampshire 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 New Hampshire, 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.
