About 0RW644Z
0RW644Z is the ICD-10-PCS code for a revision procedure on the thoracic vertebral joint using a percutaneous endoscopic 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 arthrotomy, other specified sites, the ICD-9-CM procedure title it maps to (80.19).
For a different body part, codes include 0RW044Z (occipital-cervical joint), 0RW144Z (cervical vertebral joint), 0RW444Z (cervicothoracic vertebral joint), 0RWA44Z (thoracolumbar vertebral joint), 0RWC44Z (right temporomandibular joint), 0RWD44Z (left temporomandibular joint) and 18 more.
The same procedure with a different approach is coded 0RW604Z (open), 0RW634Z (percutaneous) and 0RW6X4Z (external).
With a different device, use 0RW640Z (drainage device), 0RW643Z (infusion device), 0RW647Z (autologous tissue substitute), 0RW648Z (spacer), 0RW64AZ (interbody fusion device), 0RW64JZ (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), DRG 517 (Other Musculoskeletal System and Connective Tissue O.R. Procedures without CC/MCC), DRG 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC) and DRG 909 (Other O.R. Procedures for Injuries without CC/MCC), under the surgical categories “Other Musculoskeletal System and Connective Tissue O.R. Procedures”, “Other O.R. Procedures for Injuries” and “Other O.R. Procedures for Multiple Significant Trauma”.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
