Public records

CMS counts procedure occurrences for Original Medicare and Medicare Advantage patients. An occurrence represents a clinician, patient, date and procedure category. The count describes experience rather than treatment success.

CMS uses a source-defined one-year observation window. The public count file does not supply exact start and end dates.

A published range of 1–10 remains a range. Missing or suppressed values are not zero.

Each result stays with the clinician, group or hospital identified by its source. OpenHealth does not combine results into an overall doctor score.

New York reports isolated bypass and combined bypass or valve surgery separately. Use the procedure group that matches the proposed treatment. Each group has its own eligibility rules.

The state reports deaths during the same acute-care admission or after discharge within 30 days of the procedure. Risk-adjusted mortality accounts for measured patient risk. It estimates performance for a statewide patient mix, not your personal risk.

The state publishes case counts, observed and expected mortality, risk-adjusted mortality, 95% confidence intervals and a comparison with the statewide rate. Keep each result with its reporting period and measured clinician or hospital. A difference between two rates does not establish that one doctor is better.
