0RGS05ZFusion of Right Carpometacarpal Joint with External Fixation Device, Open Approach

0RGS05Z is the ICD-10-PCS code for a fusion procedure on the right carpometacarpal joint using an open 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 0RGL05Z (right elbow joint), 0RGM05Z (left elbow joint), 0RGN05Z (right wrist joint), 0RGP05Z (left wrist joint), 0RGQ05Z (right carpal joint), 0RGR05Z (left carpal joint) and 5 more.

The same procedure with a different approach is coded 0RGS35Z (percutaneous) and 0RGS45Z (percutaneous endoscopic).

With a different device, use 0RGS03Z (internal fixation device, sustained compression), 0RGS04Z (internal fixation device), 0RGS07Z (autologous tissue substitute), 0RGS0JZ (synthetic substitute) and 0RGS0KZ (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.
