About 0SWG34Z

0SWG34Z is the ICD-10-PCS code for a revision procedure on the left ankle joint using a percutaneous approach with internal 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, ankle, the ICD-9-CM procedure title it maps to (80.17).

For a different body part, codes include 0SW034Z (lumbar vertebral joint), 0SW334Z (lumbosacral joint), 0SW534Z (sacrococcygeal joint), 0SW634Z (coccygeal joint), 0SW734Z (right sacroiliac joint), 0SW834Z (left sacroiliac joint) and 13 more.

The same procedure with a different approach is coded 0SWG04Z (open), 0SWG44Z (percutaneous endoscopic) and 0SWGX4Z (external).

With a different device, use 0SWG30Z (drainage device), 0SWG33Z (infusion device), 0SWG35Z (external fixation device), 0SWG37Z (autologous tissue substitute), 0SWG38Z (spacer), 0SWG3JZ (synthetic substitute) and 1 more.

It is an operating-room procedure in the MS-DRG logic for DRG 492 (Lower Extremity and Humerus Procedures Except Hip, Foot and Femur with MCC or Insertion of Antibiotic-eluting Bone Void Filler), DRG 493 (Lower Extremity and Humerus Procedures Except Hip, Foot and Femur with CC), DRG 494 (Lower Extremity and Humerus Procedures Except Hip, Foot and Femur 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 “Lower Extremity and Humerus Procedures Except Hip, Foot and Femur” and “Other O.R. Procedures for Injuries”.

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