About XX20X89

XX20X89 is the ICD-10-PCS code for a monitoring procedure on the central nervous using an external approach with brain electrical activity, computer-aided detection and notification (qualifier: new technology group 9). In ICD-10-PCS, monitoring means determining the level of a physiological or physical function repetitively over a period of 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 FY2024, effective October 1, 2023.
