posterior fusion

Nicole Posted Tue 16th of October, 2018 08:33:38 AM
My Doctor is doing a l4-l5 posterior fusion with instrumentation. Is the correct coding as follows 22612, 22614 and 22840. or does 22612 cover both segments?

You should report 22612 only it covers both segments.

Arthrodesis (Fusion) implies a fusion of a motion segment, which includes two adjacent vertebrae and the intercalary disc and/or facet joints (in other words, two segments and the interspace/joints between them); therefore, coding a single fusion segment (22612 Arthrodesis, posterior or posterolateral technique, single level; lumbar (with lateral transverse technique, when performed)) involves two adjacent vertebral segments (L4 and L5).

While performing spinal fusion, physician use bone graft for which there is separate code. Please check the operative note for bone graft, determine whether the bone graft was an allograft or an autograft, and whether it was a morselized (bits or pieces) or structural (wedge or chunk) bone.
