About 00K0XZ1
00K0XZ1 is the ICD-10-PCS code for a map procedure on the brain using an external approach (qualifier: connectomic analysis). In ICD-10-PCS, map means locating the route of passage of electrical impulses and/or locating functional areas in a body part.
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 FY2025, effective October 1, 2024.
