About 0SWM04Z

0SWM04Z is the ICD-10-PCS code for a revision procedure on the right metatarsal-phalangeal joint using an open 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, foot and toe, the ICD-9-CM procedure title it maps to (80.18).

For a different body part, codes include 0SW004Z (lumbar vertebral joint), 0SW304Z (lumbosacral joint), 0SW504Z (sacrococcygeal joint), 0SW604Z (coccygeal joint), 0SW704Z (right sacroiliac joint), 0SW804Z (left sacroiliac joint) and 13 more.

The same procedure with a different approach is coded 0SWM34Z (percutaneous), 0SWM44Z (percutaneous endoscopic) and 0SWMX4Z (external).

With a different device, use 0SWM00Z (drainage device), 0SWM03Z (infusion device), 0SWM05Z (external fixation device), 0SWM07Z (autologous tissue substitute), 0SWM08Z (spacer), 0SWM0JZ (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.
