About 0SG50KZ

0SG50KZ is the ICD-10-PCS code for a fusion procedure on the sacrococcygeal joint using an open 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 spinal fusion, not otherwise specified, the ICD-9-CM procedure title it maps to (81.00).

For a different body part, codes include 0SG70KZ (right sacroiliac joint), 0SG80KZ (left sacroiliac joint), 0SG90KZ (right hip joint), 0SGB0KZ (left hip joint), 0SGC0KZ (right knee joint), 0SGD0KZ (left knee joint) and 10 more.

The same procedure with a different approach is coded 0SG53KZ (percutaneous) and 0SG54KZ (percutaneous endoscopic).

With a different device, use 0SG504Z (internal fixation device), 0SG507Z (autologous tissue substitute) and 0SG50JZ (synthetic substitute).

It is an operating-room procedure in the MS-DRG logic for DRG 028 (Spinal Procedures with MCC), DRG 029 (Spinal Procedures with CC or Spinal Neurostimulators), DRG 030 (Spinal Procedures without CC/MCC), DRG 447 (Multiple Level Spinal Fusion Except Cervical with MCC), DRG 448 (Multiple Level Spinal Fusion Except Cervical without MCC) and DRG 450 (Single Level Spinal Fusion Except Cervical with MCC), under the surgical categories “Spinal Procedures”, “Multiple Level Spinal Fusion Except Cervical”, “Single Level Spinal Fusion Except Cervical” and 3 more.

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