About XXE0X48

XXE0X48 is the ICD-10-PCS code for a measurement procedure on the central nervous using an external approach with brain electrical activity, computer-aided semiologic analysis (qualifier: new technology group 8). In ICD-10-PCS, measurement means determining the level of a physiological or physical function at a point in time.

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 FY2023, effective October 1, 2022.
