MS-DRG Coding Indicators
Statistics by Base MS-DRG
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 consistent with CMS cell size suppression policies. Only Base MS-DRGs with more than ten cases are reported.
Medical Service categories are based on groupings of patient MS-DRGs. The Base MS-DRGs in the report correspond to the Medical Service selected. MS-DRGs provide up to three levels of severity for a particular condition. A "Base" MS-DRG combines all levels of severity into a single category. The MS-DRG numbers listed are the individual MS-DRGs that have been combined into a Base MS-DRG for reporting. Individual MS-DRGs within a Base MS-DRG are differentiated according to the presence of a complication (CC) or a major complication (MCC). The descriptors of these CC/MCCs are removed when describing the Base MS-DRG.
Side-by-side statistics are reported in order to enable comparisons and benchmarking. The Hospital Statistics are for the hospital currently being reported. The Comparative Statistics are National Averages or a summarization of the Active List chosen. Each set of statistics includes:
