About 0PWN34Z

0PWN34Z is the ICD-10-PCS code for a revision procedure on the left carpal using a percutaneous 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 incision of bone without division, carpals and metacarpals, the ICD-9-CM procedure title it maps to (77.14).

For a different body part, codes include 0PW034Z (sternum), 0PW134Z (ribs, 1 to 2), 0PW234Z (ribs, 3 or more), 0PW334Z (cervical vertebra), 0PW434Z (thoracic vertebra), 0PW534Z (right scapula) and 20 more.

The same procedure with a different approach is coded 0PWN04Z (open), 0PWN44Z (percutaneous endoscopic) and 0PWNX4Z (external).

With a different device, use 0PWN35Z (external fixation device), 0PWN37Z (autologous tissue substitute), 0PWN3JZ (synthetic substitute) and 0PWN3KZ (nonautologous tissue substitute).

It is an operating-room procedure in the MS-DRG logic for DRG 513 (Hand or Wrist Procedures, Except Major Thumb or Joint Procedures with CC/MCC) and DRG 514 (Hand or Wrist Procedures, Except Major Thumb or Joint Procedures without CC/MCC), under the surgical category “Hand or Wrist Procedures, Except Major Thumb or Joint Procedures”.

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