Fusion – Number of Levels


July 10, 2014


Is a posterior L4-L5 fusion coded as 22612 (L4-L5) or 22612 (L4) with 22614 (L5)?


Good question because the CPT language can be a bit misleading. A fusion occurs at the joint between two bones; therefore, a fusion code such as 22612 requires 2 bones. So an L4-L5 fusion is 2 bones and reported with 1 code, 22612.
