About 0SWF45Z
0SWF45Z is the ICD-10-PCS code for a revision procedure on the right ankle 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.

The same procedure with a different approach is coded 0SWF05Z (open), 0SWF35Z (percutaneous) and 0SWFX5Z (external).
With a different device, use 0SWF40Z (drainage device), 0SWF43Z (infusion device), 0SWF44Z (internal fixation device), 0SWF47Z (autologous tissue substitute), 0SWF48Z (spacer), 0SWF4JZ (synthetic substitute) and 1 more.
