Outpatient Definitions and Methodology

Statistics for the Top 20 Procedures

All information in this report is taken from the Medicare Outpatient Prospective Payment System (OPPS) Limited Data Set which is updated annually by CMS based on the calendar year.  The file includes billing data for 100% of all Medicare fee-for-service claims for hospital outpatient services during the twelve months ending December 31.  The report is based on the most recent period available and is consistent with CMS cell size suppression policy.

The twenty CPT/HCPCS procedure codes with the highest total payment are ranked by amount and all others are summarized.  Averages are based on units of service (i.e. the number of units of the item or service delivered).
