About 0SWLX4Z
0SWLX4Z is the ICD-10-PCS code for a revision procedure on the left tarsometatarsal 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 0SWL04Z (open), 0SWL34Z (percutaneous) and 0SWL44Z (percutaneous endoscopic).
With a different device, use 0SWLX0Z (drainage device), 0SWLX3Z (infusion device), 0SWLX5Z (external fixation device), 0SWLX7Z (autologous tissue substitute), 0SWLX8Z (spacer), 0SWLXJZ (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.
