ICD-10-CM/PCS MS-DRGv33 Definitions Manual

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. If the CC or MCC is allowed with all principal diagnoses, then the phrase NoExcl follows the CC/MCC indicator. Otherwise, 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.
