About 0SWN35Z

0SWN35Z is the ICD-10-PCS code for a revision procedure on the left metatarsal-phalangeal joint 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 arthrotomy, foot and toe, the ICD-9-CM procedure title it maps to (80.18).

For a different body part, codes include 0SW935Z (right hip joint), 0SWB35Z (left hip joint), 0SWC35Z (right knee joint), 0SWD35Z (left knee joint), 0SWF35Z (right ankle joint), 0SWG35Z (left ankle joint) and 7 more.

The same procedure with a different approach is coded 0SWN05Z (open), 0SWN45Z (percutaneous endoscopic) and 0SWNX5Z (external).

With a different device, use 0SWN30Z (drainage device), 0SWN33Z (infusion device), 0SWN34Z (internal fixation device), 0SWN37Z (autologous tissue substitute), 0SWN38Z (spacer), 0SWN3JZ (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”.
