About 0RWT45Z

0RWT45Z is the ICD-10-PCS code for a revision procedure on the left carpometacarpal 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).

For a different body part, codes include 0RWL45Z (right elbow joint), 0RWM45Z (left elbow joint), 0RWN45Z (right wrist joint), 0RWP45Z (left wrist joint), 0RWQ45Z (right carpal joint), 0RWR45Z (left carpal joint) and 5 more.

The same procedure with a different approach is coded 0RWT05Z (open), 0RWT35Z (percutaneous) and 0RWTX5Z (external).

With a different device, use 0RWT40Z (drainage device), 0RWT43Z (infusion device), 0RWT44Z (internal fixation device), 0RWT47Z (autologous tissue substitute), 0RWT48Z (spacer), 0RWT4JZ (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”.

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