ICD-10-CM/PCS MS-DRG v42.0 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. 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.
