About 0SGC45Z

0SGC45Z is the ICD-10-PCS code for a fusion procedure on the right knee joint using a percutaneous endoscopic 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 arthrodesis of knee, the ICD-9-CM procedure title it maps to (81.22).

For a different body part, codes include 0SG945Z (right hip joint), 0SGB45Z (left hip joint), 0SGD45Z (left knee joint), 0SGF45Z (right ankle joint), 0SGG45Z (left ankle joint), 0SGH45Z (right tarsal joint) and 7 more.

The same procedure with a different approach is coded 0SGC05Z (open) and 0SGC35Z (percutaneous).

With a different device, use 0SGC43Z (internal fixation device, sustained compression), 0SGC44Z (internal fixation device), 0SGC47Z (autologous tissue substitute), 0SGC4JZ (synthetic substitute) and 0SGC4KZ (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.
