About 0PWS4KZ

0PWS4KZ is the ICD-10-PCS code for a revision procedure on the left thumb phalanx using a percutaneous endoscopic 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 incision of bone without division, other bones, the ICD-9-CM procedure title it maps to (77.19).

For a different body part, codes include 0PW04KZ (sternum), 0PW14KZ (ribs, 1 to 2), 0PW24KZ (ribs, 3 or more), 0PW34KZ (cervical vertebra), 0PW44KZ (thoracic vertebra), 0PW54KZ (right scapula) and 20 more.

The same procedure with a different approach is coded 0PWS0KZ (open), 0PWS3KZ (percutaneous) and 0PWSXKZ (external).

With a different device, use 0PWS44Z (internal fixation device), 0PWS45Z (external fixation device), 0PWS47Z (autologous tissue substitute) and 0PWS4JZ (synthetic substitute).

It is an operating-room procedure in the MS-DRG logic for DRG 495 (Local Excision and Removal of Internal Fixation Devices Except Hip and Femur with MCC), DRG 496 (Local Excision and Removal of Internal Fixation Devices Except Hip and Femur with CC) and DRG 497 (Local Excision and Removal of Internal Fixation Devices Except Hip and Femur without CC/MCC), under the surgical category “Local Excision and Removal of Internal Fixation Devices Except Hip and Femur”.

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