Which MS-DRGs does T84.090A group to?
T84.090A sits in MDC 08 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.
- 559Aftercare, Musculoskeletal System and Connective Tissue with MCCmedical
- 560Aftercare, Musculoskeletal System and Connective Tissue with CCmedical
- 561Aftercare, Musculoskeletal System and Connective Tissue without CC/MCCmedical
As a secondary diagnosis, T84.090A is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.
