Which MS-DRGs does C75.0 group to?

C75.0 sits in MDC 10 and helps define the logic of 3 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.

643Endocrine Disorders with MCCmedical
644Endocrine Disorders with CCmedical
645Endocrine Disorders without CC/MCCmedical

As a secondary diagnosis, C75.0 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.
