ICD-10-CM/PCS MS-DRG v43.1 Definitions Manual
Skip to content

Appendix C is a list of all of the codes that are defined as either a complication or comorbidity (CC) or a major complication or comorbidity (MCC) when used as a secondary diagnosis.

Part 1 lists these codes. Each code is indicated as CC or MCC, as well as the HAC category (if applicable) the code is assigned to. Hover over the HAC number for its description. A link is given to a collection of diagnosis codes which, when used as the principal diagnosis, will cause the CC or MCC to be considered as only a non-CC.

Part 2 lists codes which are assigned as a Major CC only for patients discharged alive. Otherwise they are assigned as a non-CC.

Part 3 lists diagnosis codes that are designated as a complication or comorbidity (CC) or major complication or comorbidity (MCC) and included in the definition of the logic for the listed DRGs. When reported as a secondary diagnosis and grouped to one of the listed DRGs the diagnosis is excluded from acting as a CC/MCC for severity in DRG assignment.
