About 0PWNXKZ

0PWNXKZ is the ICD-10-PCS code for a revision procedure on the left carpal using an external approach with nonautologous tissue substitute. 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 0PW0XKZ (sternum), 0PW1XKZ (ribs, 1 to 2), 0PW2XKZ (ribs, 3 or more), 0PW3XKZ (cervical vertebra), 0PW4XKZ (thoracic vertebra), 0PW5XKZ (right scapula) and 20 more.

The same procedure with a different approach is coded 0PWN0KZ (open), 0PWN3KZ (percutaneous) and 0PWN4KZ (percutaneous endoscopic).

With a different device, use 0PWNX4Z (internal fixation device), 0PWNX5Z (external fixation device), 0PWNX7Z (autologous tissue substitute) and 0PWNXJZ (synthetic 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.
