Which MS-DRGs does T85.840D group to?
T85.840D sits in MDC 23 and helps define the logic of 2 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.
- 949Aftercare with CC/MCCmedical
- 950Aftercare without CC/MCCmedical
As a secondary diagnosis, T85.840D is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.
