Which MS-DRGs does T85.690A group to?

T85.690A sits in MDC 01 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.

  • 091Other Disorders of Nervous System with MCCmedical
  • 092Other Disorders of Nervous System with CCmedical
  • 093Other Disorders of Nervous System without CC/MCCmedical

As a secondary diagnosis, T85.690A is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.
