ICD-10-CM/PCS MS-DRG v43.0 Definitions Manual
Skip to content

The first section of the Procedure Code/MS-DRG Index is a reference source of all ICD-10-PCS procedure codes that affect MS-DRG assignment, the MDCs and MS-DRGs to which they are assigned, and a description of the surgical categories. The procedure codes are listed in code order with an * indicating the non-operating room procedures. All procedures without an * are considered OPERATING ROOM PROCEDURES by the MS-DRGs. A + beside a procedure code indicates that it is also a member of a Procedure Code Combination, also called a 'Procedure Cluster'. These are combinations of procedures, which, when reported, are grouped differently than their constituent codes. Each procedure code is listed in the second section of this Appendix with the MDC and MS-DRG surgical categories to which the procedure code cluster is assigned. The third section of this Appendix lists a few procedure code combinations for which the combination is designated as non-OR even though one or more of the procedures in the combination are designated as an O.R. procedure. The fourth section of this Appendix lists those procedure codes that are specific to the logic for assignment to any surgical MS-DRG in MDC 14.
