About 0PWS35Z

0PWS35Z is the ICD-10-PCS code for a revision procedure on the left thumb phalanx using a percutaneous 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, other bones, the ICD-9-CM procedure title it maps to (77.19).

For a different body part, codes include 0PWC35Z (right humeral head), 0PWD35Z (left humeral head), 0PWF35Z (right humeral shaft), 0PWG35Z (left humeral shaft), 0PWH35Z (right radius), 0PWJ35Z (left radius) and 9 more.

The same procedure with a different approach is coded 0PWS05Z (open), 0PWS45Z (percutaneous endoscopic) and 0PWSX5Z (external).

With a different device, use 0PWS34Z (internal fixation device), 0PWS37Z (autologous tissue substitute), 0PWS3JZ (synthetic substitute) and 0PWS3KZ (nonautologous tissue 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.
