About 0SG10AJ

0SG10AJ is the ICD-10-PCS code for a fusion procedure on the lumbar vertebral joints, 2 or more using an open approach with interbody fusion device (qualifier: posterior approach, anterior column). 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 lumbar and lumbosacral fusion of the anterior column, posterior technique, fusion or refusion of 2-3 vertebrae, fusion or refusion of 4-8 vertebrae and 1 more, the ICD-9-CM procedure titles it maps to (81.08, 81.62, 81.63 and 1 more).

For a different body part, codes include 0SG00AJ (lumbar vertebral joint) and 0SG30AJ (lumbosacral joint).

The same procedure with a different approach is coded 0SG13AJ (percutaneous) and 0SG14AJ (percutaneous endoscopic).

With a different device, use 0SG107J (autologous tissue substitute), 0SG10EJ (interbody fusion device, custom-made anatomically and virtually designed), 0SG10JJ (synthetic substitute) and 0SG10KJ (nonautologous tissue 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 426 (Multiple Level Combined Anterior and Posterior Spinal Fusion Except Cervical with MCC), DRG 427 (Multiple Level Combined Anterior and Posterior Spinal Fusion Except Cervical with CC) and DRG 428 (Multiple Level Combined Anterior and Posterior Spinal Fusion Except Cervical without CC/MCC), under the surgical categories “Spinal Procedures”, “Multiple Level Combined Anterior and Posterior Spinal Fusion Except Cervical”, “Multiple Level Spinal Fusion Except Cervical” and 3 more.

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