About 00P04YZ

00P04YZ is the ICD-10-PCS code for a removal procedure on the brain using a percutaneous endoscopic approach with other device. In ICD-10-PCS, removal means taking out or off a device from a body part.

In plain terms, this corresponds to other incision of brain, the ICD-9-CM procedure title it maps to (01.39).

For a different body part, codes include 00P64YZ (cerebral ventricle), 00PE4YZ (cranial nerve), 00PU4YZ (spinal canal) and 00PV4YZ (spinal cord).

The same procedure with a different approach is coded 00P00YZ (open) and 00P03YZ (percutaneous).

With a different device, use 00P040Z (drainage device), 00P042Z (monitoring device), 00P043Z (infusion device), 00P047Z (autologous tissue substitute), 00P04JZ (synthetic substitute), 00P04KZ (nonautologous tissue substitute) and 1 more.

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 FY2018, effective October 1, 2017.
