About 0SW638Z
0SW638Z is the ICD-10-PCS code for a revision procedure on the coccygeal joint using a percutaneous approach with spacer. 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 0SW038Z (lumbar vertebral joint), 0SW338Z (lumbosacral joint), 0SW538Z (sacrococcygeal joint), 0SW738Z (right sacroiliac joint), 0SW838Z (left sacroiliac joint), 0SW938Z (right hip joint) and 13 more.
The same procedure with a different approach is coded 0SW608Z (open), 0SW648Z (percutaneous endoscopic) and 0SW6X8Z (external).
With a different device, use 0SW630Z (drainage device), 0SW633Z (infusion device), 0SW634Z (internal fixation device), 0SW637Z (autologous tissue substitute), 0SW63JZ (synthetic substitute) and 0SW63KZ (nonautologous tissue substitute).
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.
