- Why are some measure values suppressed for GSI ASC LLC?
- CMS suppresses measure values when a facility has fewer than 11 qualifying cases in a reporting period (footnote "5"). Suppressed measures appear as "Suppressed (<11 cases)" on this page. Suppression does not indicate poor quality — it is a CMS methodology requirement to protect patient privacy.
- Why is ASC-12 shown as a category rather than a percentage?
- ASC-12 measures the rate of unplanned visits after colonoscopy. CMS reports ASC-12 as a performance category ("Better Than the National Rate," "No Different Than the National Rate," or "Worse Than the National Rate") rather than a raw percentage, because it is a risk-adjusted outcome measure that CMS benchmarks against the national norm.
