About 0RWR45Z

0RWR45Z is the ICD-10-PCS code for a revision procedure on the left carpal joint using a percutaneous endoscopic approach with external 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, hand and finger, the ICD-9-CM procedure title it maps to (80.14).

The same procedure with a different approach is coded 0RWR05Z (open), 0RWR35Z (percutaneous) and 0RWRX5Z (external).

With a different device, use 0RWR40Z (drainage device), 0RWR43Z (infusion device), 0RWR44Z (internal fixation device), 0RWR47Z (autologous tissue substitute), 0RWR48Z (spacer), 0RWR4JZ (synthetic substitute) and 1 more.

It is an operating-room procedure in the MS-DRG logic for DRG 506 (Major Thumb or Joint Procedures) and DRG 906 (Hand Procedures for Injuries), under the surgical categories “Major Thumb or Joint Procedures” and “Hand Procedures for Injuries”.
