0RGX04ZFusion of Left Finger Phalangeal Joint with Internal Fixation Device, Open Approach

0RGX04Z is the ICD-10-PCS code for a fusion procedure on the left finger phalangeal joint using an open approach with internal 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 interphalangeal fusion, the ICD-9-CM procedure title it maps to (81.28).

For a different body part, codes include 0RGC04Z (right temporomandibular joint), 0RGD04Z (left temporomandibular joint), 0RGE04Z (right sternoclavicular joint), 0RGF04Z (left sternoclavicular joint), 0RGG04Z (right acromioclavicular joint), 0RGH04Z (left acromioclavicular joint) and 13 more.

The same procedure with a different approach is coded 0RGX34Z (percutaneous) and 0RGX44Z (percutaneous endoscopic).

With a different device, use 0RGX03Z (internal fixation device, sustained compression), 0RGX05Z (external fixation device), 0RGX07Z (autologous tissue substitute), 0RGX0JZ (synthetic substitute) and 0RGX0KZ (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.
