Summary & Overview
Other Musculoskeletal System and Connective Tissue Diagnoses with MCC: Inpatient Reimbursement Overview
DRG 564 encompasses other musculoskeletal system and connective tissue diagnoses accompanied by a Major Complication or Comorbidity, representing higher-severity inpatient cases. It matters for inpatient reimbursement because the Major Complication or Comorbidity designation increases expected resource use and thus affects Medicare payment under the Diagnosis-Related Group framework.
DRG 564 Overview
DRG 564 covers hospital admissions for other musculoskeletal system and connective tissue diagnoses when a Major Complication or Comorbidity is present. This includes a range of complex orthopedic and connective tissue conditions with significant complications that increase resource use. The presence of a Major Complication or Comorbidity elevates payment relative to lower-severity groupings because of higher anticipated costs for inpatient care. Accurate coding of diagnoses and complications is central to correct Medicare payment in this Diagnosis-Related Group.
