Medical DRGOther Circulatory System Diagnoses with MCC
What is MS-DRG 314?
MS-DRG 314 is a Medical Medicare Severity Diagnosis Related Group under Major Diagnostic Category 05 (MDC 05) with a Major Complication or Comorbidity (MCC). It maps to 257 ICD-10-CM diagnosis codes. For FY 2026 it carries a relative weight of 2.0852 with a geometric mean length of stay of 4.8 days and an arithmetic mean of 6.7 days. Hospitals use this grouping to determine reimbursement for inpatient stays under Medicare.
