Question: Our surgeon recently used a new system called "PEEK" for an interbody fusion using bone morphogenic protein. Is there a code for this? Answer: "PEEK" stands for poly-ethyl ethyl ketone and describes a type of synthetic interbody cage. The appropriate code for this is 22851 (Application of intervertebral biomechanical device[s] [e.g., synthetic cage(s), threaded bone dowel(s), methylmethacrylate] to vertebral defect or interspace). - Clinical and coding expertise for You Be the Coder and Reader Questions provided by Eric Sandham, CHC, CPC, compliance manager for Central California Faculty Medical Group, a group practice and training facility associated with the University of California at San Francisco in Fresno.
