About 0SWK45Z

0SWK45Z is the ICD-10-PCS code for a revision procedure on the right tarsometatarsal joint 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 arthrotomy, foot and toe, the ICD-9-CM procedure title it maps to (80.18).

For a different body part, codes include 0SW945Z (right hip joint), 0SWB45Z (left hip joint), 0SWC45Z (right knee joint), 0SWD45Z (left knee joint), 0SWF45Z (right ankle joint), 0SWG45Z (left ankle joint) and 7 more.

The same procedure with a different approach is coded 0SWK05Z (open), 0SWK35Z (percutaneous) and 0SWKX5Z (external).

With a different device, use 0SWK40Z (drainage device), 0SWK43Z (infusion device), 0SWK44Z (internal fixation device), 0SWK47Z (autologous tissue substitute), 0SWK48Z (spacer), 0SWK4JZ (synthetic substitute) and 1 more.

It is an operating-room procedure in the MS-DRG logic for DRG 503 (Foot Procedures with MCC), DRG 504 (Foot Procedures with CC), DRG 505 (Foot Procedures without CC/MCC), DRG 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC) and DRG 909 (Other O.R. Procedures for Injuries without CC/MCC), under the surgical categories “Foot Procedures” and “Other O.R. Procedures for Injuries”.

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