Which MS-DRGs does E27.2 group to?

E27.2 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, E27.2 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.
