About 0PWN45Z

0PWN45Z is the ICD-10-PCS code for a revision procedure on the left carpal using a percutaneous endoscopic approach with external 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 0PWC45Z (right humeral head), 0PWD45Z (left humeral head), 0PWF45Z (right humeral shaft), 0PWG45Z (left humeral shaft), 0PWH45Z (right radius), 0PWJ45Z (left radius) and 9 more.

The same procedure with a different approach is coded 0PWN05Z (open), 0PWN35Z (percutaneous) and 0PWNX5Z (external).

With a different device, use 0PWN44Z (internal fixation device), 0PWN47Z (autologous tissue substitute), 0PWN4JZ (synthetic substitute) and 0PWN4KZ (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.
