About 0SW04AZ

0SW04AZ is the ICD-10-PCS code for a revision procedure on the lumbar vertebral joint using a percutaneous endoscopic 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 arthrotomy, other specified sites, the ICD-9-CM procedure title it maps to (80.19).

For a different body part, codes include 0SW34AZ (lumbosacral joint).

The same procedure with a different approach is coded 0SW00AZ (open), 0SW03AZ (percutaneous) and 0SW0XAZ (external).

With a different device, use 0SW040Z (drainage device), 0SW043Z (infusion device), 0SW044Z (internal fixation device), 0SW047Z (autologous tissue substitute), 0SW048Z (spacer), 0SW04JZ (synthetic substitute) and 1 more.

It is an operating-room procedure in the MS-DRG logic for DRG 515 (Other Musculoskeletal System and Connective Tissue O.R. Procedures with MCC), DRG 516 (Other Musculoskeletal System and Connective Tissue O.R. Procedures with CC) and DRG 517 (Other Musculoskeletal System and Connective Tissue O.R. Procedures without CC/MCC), under the surgical category “Other Musculoskeletal System and Connective Tissue O.R. Procedures”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
