MS-DRG 180: RESPIRATORY NEOPLASMS WITH MCC
MS-DRG 180 is respiratory neoplasms with mcc, in MDC 04 (a medical DRG), at the with-MCC (major complication or comorbidity) level. Its FY2027 relative weight is 1.7806, so a case here pays more than the average Medicare inpatient stay (weight 1.0), with a geometric mean length of stay of 4.70 days. 64 ICD-10-CM principal diagnoses group into MS-DRGs 180–182 under the CMS definitions manual; the most-searched are listed below.

Principal diagnoses that group to MS-DRGs 180–182
From the CMS MS-DRG definitions manual’s principal-diagnosis index: 64 ICD-10-CM codes route here, and the CC/MCC status of the secondary diagnoses decides which of 180–182 the case lands in. The 24 most-searched:
