Please help with CPT codes: C4-C5 cervical stenosis
1.Arthrodesis via anterior interbody technique C4-C5
2.Application of intervertebral biomechanical device C4-C5
3.Anterior instrumentation C4-C5
4.Intraoperative microscope

Through transverse incision centered above clavicle left side of cervical fascia. First performed deskectomy at the C4-5 level back to level of uncovertebral joints. this performed without incident and a complete decompression was performed after taking down stenosis at the C4-5 level posteriorly at the level of the spinal cord proper and the exiting nerve roots. Next, using DePuy guide, I placed a size 7 bone dowel acting as intervertebral biomechanical device at the C4-5 level. anterior instrumentation consisting of a skyline plate was placed across the C4-5 level. anterior instrumentation was then deployed through the plate and final locking was performed.
