About 0SW3XAZ

0SW3XAZ is the ICD-10-PCS code for a revision procedure on the lumbosacral joint using an external approach with interbody fusion 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 0SW0XAZ (lumbar vertebral joint).

The same procedure with a different approach is coded 0SW30AZ (open), 0SW33AZ (percutaneous) and 0SW34AZ (percutaneous endoscopic).

With a different device, use 0SW3X0Z (drainage device), 0SW3X3Z (infusion device), 0SW3X4Z (internal fixation device), 0SW3X7Z (autologous tissue substitute), 0SW3X8Z (spacer), 0SW3XJZ (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.
