About 4B0FXVZ

4B0FXVZ is the ICD-10-PCS code for a measurement procedure on the musculoskeletal using an external approach with stimulator. In ICD-10-PCS, measurement means determining the level of a physiological or physical function at a point in time.

In plain terms, this corresponds to other nonoperative neurologic function tests, the ICD-9-CM procedure title it maps to (89.15).

For a different body part, codes include 4B00XVZ (central nervous) and 4B01XVZ (peripheral nervous).

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

It has been valid since ICD-10-PCS took effect on October 1, 2015.
