MS-DRG 299: PERIPHERAL VASCULAR DISORDERS WITH MCC
MS-DRG 299 is peripheral vascular disorders with mcc, in MDC 05 (a medical DRG), at the with-MCC (major complication or comorbidity) level. Its FY2027 relative weight is 1.5842, so a case here pays more than the average Medicare inpatient stay (weight 1.0), with a geometric mean length of stay of 3.90 days. 1,234 ICD-10-CM principal diagnoses group into MS-DRGs 299–301 under the CMS definitions manual; the most-searched are listed below.
