What is MS-DRG 063?
MS-DRG 063 is a Medical Medicare Severity Diagnosis Related Group under Major Diagnostic Category 01 (MDC 01) without a significant Complication or Comorbidity. It maps to 130 ICD-10-CM diagnosis codes. For FY 2026 it carries a relative weight of 1.4038 with a geometric mean length of stay of 2.2 days and an arithmetic mean of 2.5 days. Hospitals use this grouping to determine reimbursement for inpatient stays under Medicare.
