Coding posterior spinal fusion

In the posterior, posterolateral or  lateral transverse process spinal fusion approach, the spine is accessed by an incision on the back and arthrodesis is accomplished. 22590-22632

PREOPERATIVE DIAGNOSIS:

Lumbar stenosis, neurogenic claudication and radiculopathy, degenerative joint

disease, spondylolisthesis.

POSTOPERATIVE DIAGNOSIS:

Same as above.

PROCEDURE:

1. L4—L5 posterior spinal fusion.

2. L4—L5 posterior instrumentation with interspinous process plate from Life Spine.

3. L2, L3, L4, L5 bilateral laminotomy with partial medial facetectomy and foraninotomy for

decompression.

7. Use of morselized autograft of the spine taken through the same incision.

8. Use of structural allograft.
