0RGR45ZFusion of Left Carpal Joint with External Fixation Device, Percutaneous Endoscopic Approach

0RGR45Z is the ICD-10-PCS code for a fusion procedure on the left carpal joint using a percutaneous endoscopic approach with external fixation device. In ICD-10-PCS, fusion means joining together portions of an articular body part rendering the articular body part immobile.

In plain terms, this corresponds to Metacarpocarpal fusion, the ICD-9-CM procedure title it maps to (81.26).

For a different body part, codes include 0RGL45Z (right elbow joint), 0RGM45Z (left elbow joint), 0RGN45Z (right wrist joint), 0RGP45Z (left wrist joint), 0RGQ45Z (right carpal joint), 0RGS45Z (right carpometacarpal joint) and 5 more.

The same procedure with a different approach is coded 0RGR05Z (open) and 0RGR35Z (percutaneous).

With a different device, use 0RGR43Z (internal fixation device, sustained compression), 0RGR44Z (internal fixation device), 0RGR47Z (autologous tissue substitute), 0RGR4JZ (synthetic substitute) and 0RGR4KZ (nonautologous tissue substitute).

It is an operating-room procedure in the MS-DRG logic for DRG 513 (Hand or Wrist Procedures, Except Major Thumb or Joint Procedures with CC/MCC), DRG 514 (Hand or Wrist Procedures, Except Major Thumb or Joint Procedures without CC/MCC), DRG 906 (Hand Procedures for Injuries), DRG 957 (Other O.R. Procedures for Multiple Significant Trauma with MCC), DRG 958 (Other O.R. Procedures for Multiple Significant Trauma with CC) and DRG 959 (Other O.R. Procedures for Multiple Significant Trauma without CC/MCC), under the surgical categories “Hand or Wrist Procedures, Except Major Thumb or Joint Procedures”, “Hand 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.
