About 0PWNX4Z

0PWNX4Z is the ICD-10-PCS code for a revision procedure on the left carpal using an external approach with internal fixation device. In ICD-10-PCS, revision means correcting, to the extent possible, a portion of a malfunctioning device or the position of a displaced device.

In plain terms, this corresponds to other miscellaneous procedures, the ICD-9-CM procedure title it maps to (99.99).

For a different body part, codes include 0PW0X4Z (sternum), 0PW1X4Z (ribs, 1 to 2), 0PW2X4Z (ribs, 3 or more), 0PW3X4Z (cervical vertebra), 0PW4X4Z (thoracic vertebra), 0PW5X4Z (right scapula) and 20 more.

The same procedure with a different approach is coded 0PWN04Z (open), 0PWN34Z (percutaneous) and 0PWN44Z (percutaneous endoscopic).

With a different device, use 0PWNX5Z (external fixation device), 0PWNX7Z (autologous tissue substitute), 0PWNXJZ (synthetic substitute) and 0PWNXKZ (nonautologous tissue substitute).

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.
