About 0SWFX4Z
0SWFX4Z is the ICD-10-PCS code for a revision procedure on the right ankle joint using an external 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 miscellaneous procedures, the ICD-9-CM procedure title it maps to (99.99).
For a different body part, codes include 0SW0X4Z (lumbar vertebral joint), 0SW3X4Z (lumbosacral joint), 0SW5X4Z (sacrococcygeal joint), 0SW6X4Z (coccygeal joint), 0SW7X4Z (right sacroiliac joint), 0SW8X4Z (left sacroiliac joint) and 13 more.
The same procedure with a different approach is coded 0SWF04Z (open), 0SWF34Z (percutaneous) and 0SWF44Z (percutaneous endoscopic).
With a different device, use 0SWFX0Z (drainage device), 0SWFX3Z (infusion device), 0SWFX5Z (external fixation device), 0SWFX7Z (autologous tissue substitute), 0SWFX8Z (spacer), 0SWFXJZ (synthetic substitute) and 1 more.
It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
