About 0SGC04Z

0SGC04Z is the ICD-10-PCS code for a fusion procedure on the right knee 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 arthrodesis of knee, the ICD-9-CM procedure title it maps to (81.22).

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), 0SGD04Z (left knee joint) and 10 more.

The same procedure with a different approach is coded 0SGC34Z (percutaneous) and 0SGC44Z (percutaneous endoscopic).

With a different device, use 0SGC03Z (internal fixation device, sustained compression), 0SGC05Z (external fixation device), 0SGC07Z (autologous tissue substitute), 0SGC0JZ (synthetic substitute) and 0SGC0KZ (nonautologous tissue substitute).

It is an operating-room procedure in the MS-DRG logic for DRG 400 (Knee Procedures with Principal Diagnosis of Infection), DRG 488 (Knee Procedures without Principal Diagnosis of Infection with CC/MCC), DRG 489 (Knee Procedures without Principal Diagnosis of Infection without CC/MCC), DRG 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC) and DRG 909 (Other O.R. Procedures for Injuries without CC/MCC), under the surgical categories “Knee Procedures with Principal Diagnosis of Infection”, “Knee Procedures without Principal Diagnosis of Infection”, “Other O.R. Procedures for Injuries” and 1 more.

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