MS-DRG Mapping for ICD-10-PCS Code X2U4079

ICD-10-PCS procedure codes are grouped into Medicare Severity Diagnosis Related Groups (MS-DRGs) to support consistent hospital reimbursement and care planning. MS-DRGs classify inpatient stays based on clinical similarity and expected resource use, using information such as the primary procedure, secondary diagnoses, and patient condition.

Each hospital stay is assigned a single DRG, which determines a fixed payment rate from Medicare. This rate accounts for the complexity of the procedure and the overall cost of care.

The code X2U4079 maps to the following MS-DRGs in version V43.0, effective from October 1, 2025, through September 30, 2026. These groupings are key to understanding how the procedure impacts billing and hospital resource allocation.
