DRGMedicalMDC 04

MS-DRG 190 is chronic obstructive pulmonary disease with mcc, in MDC 04 (a medical DRG), at the with-MCC (major complication or comorbidity) level. Its FY2027 relative weight is 1.0748, so a case here pays more than the average Medicare inpatient stay (weight 1.0), with a geometric mean length of stay of 3.30 days. 23 ICD-10-CM principal diagnoses group into MS-DRGs 190–192 under the CMS definitions manual; the most-searched are listed below.
