What is MS-DRG 023?
MS-DRG 023 is the Medicare Severity Diagnosis-Related Group for CRANIOTOMY WITH MAJOR DEVICE IMPLANT OR ACUTE COMPLEX CNS PRINCIPAL DIAGNOSIS WITH MCC O. When a Medicare patient is discharged, the hospital stay is grouped into a single MS-DRG, and Medicare reimburses the hospital a fixed, predetermined amount for that group rather than itemizing each service.
Across the CMS Medicare Inpatient Hospitals by Provider dataset, 469 hospitals reported 22,961 discharges for MS-DRG 023. The average hospital submitted charge was $272K, while the average amount Medicare actually paid was $46K — a 5.9× gap between list price and reimbursement, which is typical for Medicare inpatient claims.
