MS-DRG 102: HEADACHES WITH MCC
MS-DRG 102 is headaches with mcc, in MDC 01 (a medical DRG), at the with-MCC (major complication or comorbidity) level. Its FY2027 relative weight is 1.1201, so a case here pays more than the average Medicare inpatient stay (weight 1.0), with a geometric mean length of stay of 2.90 days. 95 ICD-10-CM principal diagnoses group into MS-DRGs 102–103 under the CMS definitions manual; the most-searched are listed below.

Principal diagnoses that group to MS-DRGs 102–103
From the CMS MS-DRG definitions manual’s principal-diagnosis index: 95 ICD-10-CM codes route here, and the CC/MCC status of the secondary diagnoses decides which of 102–103 the case lands in. The 24 most-searched:
