Knee Procedures with Principal Diagnosis of Infection with MCC: Inpatient Reimbursement Overview
DRG 485 encompasses knee procedures where the principal diagnosis is infection accompanied by a Major Complication or Comorbidity; it covers operative and perioperative care related to infected native knees or prosthetic joint infections. This Diagnosis-Related Group is important for inpatient reimbursement because infection and Major Complication or Comorbidity status increase expected resource consumption and affect Medicare payment classification.
DRG 485 Overview
DRG 485 covers knee procedures performed when the principal diagnosis is an infection with Major Complication or Comorbidity. This category captures cases that typically require operative intervention for infected knee joints or prostheses and often involve intensive medical management. It matters for Medicare payment because the presence of infection and a Major Complication or Comorbidity significantly increases resource use and drives higher Diagnosis-Related Group reimbursement. Accurate clinical documentation of the infection and associated Major Complication or Comorbidity is essential for appropriate assignment to this Diagnosis-Related Group.
