MS-DRG 192: CHRONIC OBSTRUCTIVE PULMONARY DISEASE WITHOUT CC/MCC
MS-DRG 192 is chronic obstructive pulmonary disease without cc/mcc, in MDC 04 (a medical DRG), at the without-CC/MCC level. Its FY2027 relative weight is 0.6288, so a case here pays less than the average Medicare inpatient stay (weight 1.0), with a geometric mean length of stay of 2.10 days. 23 ICD-10-CM principal diagnoses group into MS-DRGs 190–192 under the CMS definitions manual; the most-searched are listed below.
