About 0SGF04Z

0SGF04Z is the ICD-10-PCS code for a fusion procedure on the right ankle 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 ankle fusion, the ICD-9-CM procedure title it maps to (81.11).

For a different body part, codes include 0SG504Z (sacrococcygeal joint), 0SG704Z (right sacroiliac joint), 0SG804Z (left sacroiliac joint), 0SG904Z (right hip joint), 0SGB04Z (left hip joint), 0SGC04Z (right knee joint) and 10 more.

The same procedure with a different approach is coded 0SGF34Z (percutaneous) and 0SGF44Z (percutaneous endoscopic).

With a different device, use 0SGF03Z (internal fixation device, sustained compression), 0SGF05Z (external fixation device), 0SGF07Z (autologous tissue substitute), 0SGF0JZ (synthetic substitute) and 0SGF0KZ (nonautologous tissue substitute).

It is an operating-room procedure in the MS-DRG logic for DRG 492 (Lower Extremity and Humerus Procedures Except Hip, Foot and Femur with MCC or Insertion of Antibiotic-eluting Bone Void Filler), DRG 493 (Lower Extremity and Humerus Procedures Except Hip, Foot and Femur with CC), DRG 494 (Lower Extremity and Humerus Procedures Except Hip, Foot and Femur without CC/MCC), DRG 628 (Other Endocrine, Nutritional and Metabolic O.R. Procedures with MCC or Insertion of Antibiotic-eluting Bone Void Filler), DRG 629 (Other Endocrine, Nutritional and Metabolic O.R. Procedures with CC) and DRG 630 (Other Endocrine, Nutritional and Metabolic O.R. Procedures without CC/MCC), under the surgical categories “Lower Extremity and Humerus Procedures Except Hip, Foot and Femur”, “Other Endocrine, Nutritional and Metabolic O.R. Procedures”, “Other O.R. Procedures for Injuries” and 1 more.

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