About 0SW0X4Z

0SW0X4Z is the ICD-10-PCS code for a revision procedure on the lumbar vertebral 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 0SW3X4Z (lumbosacral joint), 0SW5X4Z (sacrococcygeal joint), 0SW6X4Z (coccygeal joint), 0SW7X4Z (right sacroiliac joint), 0SW8X4Z (left sacroiliac joint), 0SW9X4Z (right hip joint) and 13 more.

The same procedure with a different approach is coded 0SW004Z (open), 0SW034Z (percutaneous) and 0SW044Z (percutaneous endoscopic).

With a different device, use 0SW0X0Z (drainage device), 0SW0X3Z (infusion device), 0SW0X7Z (autologous tissue substitute), 0SW0X8Z (spacer), 0SW0XAZ (interbody fusion device), 0SW0XJZ (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.
