About 0WH133Z

0WH133Z is the ICD-10-PCS code for a insertion procedure on the cranial cavity using a percutaneous approach with infusion device. In ICD-10-PCS, insertion means putting in a nonbiological appliance that monitors, assists, performs, or prevents a physiological function but does not physically take the place of a body part.

In plain terms, this corresponds to insertion of catheter(s) into cranial cavity or tissue, the ICD-9-CM procedure title it maps to (01.26).

For a different body part, codes include 0WH033Z (head), 0WH233Z (face), 0WH333Z (oral cavity and throat), 0WH433Z (upper jaw), 0WH533Z (lower jaw), 0WH633Z (neck) and 16 more.

The same procedure with a different approach is coded 0WH103Z (open) and 0WH143Z (percutaneous endoscopic).

With a different device, use 0WH131Z (radioactive element) and 0WH13YZ (other device).

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.
