Which MS-DRGs does D59.12 group to?
D59.12 sits in MDC 16 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.
- 808Major Hematological and Immunological Diagnoses Except Sickle Cell Crisis and Coagulation Disorders with MCCmedical
- 809Major Hematological and Immunological Diagnoses Except Sickle Cell Crisis and Coagulation Disorders with CCmedical
- 810Major Hematological and Immunological Diagnoses Except Sickle Cell Crisis and Coagulation Disorders without CC/MCCmedical
As a secondary diagnosis, D59.12 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.
