Which MS-DRGs does C49.3 group to?

C49.3 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.

  • 542Pathological Fractures and Musculoskeletal and Connective Tissue Malignancy with MCCmedical
  • 543Pathological Fractures and Musculoskeletal and Connective Tissue Malignancy with CCmedical
  • 544Pathological Fractures and Musculoskeletal and Connective Tissue Malignancy without CC/MCCmedical

As a secondary diagnosis, C49.3 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.

  • malignant neoplasm of heart (C38.0)
  • malignant neoplasm of mediastinum (C38.1-C38.3)
  • malignant neoplasm of thymus (C37)
