About 6A4T00A

6A4T00A is the ICD-10-PCS code for a hypothermia procedure on the urinary system using a single approach with donor organ protective thermal insulation (qualifier: intraoperative). In ICD-10-PCS, hypothermia means extracorporeal lowering of body temperature.

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

It was added in FY2026, effective October 1, 2025.
