All information in this report is taken from the Medicare Provider Analysis and Review (MedPAR) file which is updated annually by CMS based on the federal fiscal year.  The file includes billing data for 100% of all Medicare fee-for-service claims (IPPS claims) for discharges during the twelve months ending September 30.  The report is based on the most recent period available and is consistent with CMS cell size suppression policies. Only procedures with more than ten cases are reported.

The twenty procedures appearing on highest numbers of cases are ranked by volume (i.e. sum of principal diagnosis cases plus secondary diagnosis cases). Report totals are not calculated because multiple diagnoses may appear on a claim.

Proc Code

an ICD-9-CM procedure code that defines a surgical or other treatment procedure. The International Statistical Classification of Diseases and Related Health Problems (most commonly known by the abbreviation ICD) provides codes to classify procedures appearing on a Medicare fee-for-service inpatient claim. The International Classification of Diseases is published by the World Health Organization and is revised periodically. The ninth revision is used for the period being reported.
