About 0RGS4KZ
0RGS4KZ is the ICD-10-PCS code for a fusion procedure on the right carpometacarpal joint using a percutaneous endoscopic approach with nonautologous tissue substitute. 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 0RGC4KZ (right temporomandibular joint), 0RGD4KZ (left temporomandibular joint), 0RGE4KZ (right sternoclavicular joint), 0RGF4KZ (left sternoclavicular joint), 0RGG4KZ (right acromioclavicular joint), 0RGH4KZ (left acromioclavicular joint) and 13 more.
The same procedure with a different approach is coded 0RGS0KZ (open) and 0RGS3KZ (percutaneous).
With a different device, use 0RGS43Z (internal fixation device, sustained compression), 0RGS44Z (internal fixation device), 0RGS45Z (external fixation device), 0RGS47Z (autologous tissue substitute) and 0RGS4JZ (synthetic 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.
