CPT 20670

Question: I reported CPT code 21453, Closed treatment of mandibular fracture with interdental fixation, for a closed treatment of mandibular fracture with interdental fixation using arch bars. I am unable to locate a specific code for arch bar removal. Can I report CPT code 20670, Removal of implant; superficial, (eg, buried wire, pin or rod) (separate procedure), for the subsequent removal of the arch bars? Or is there a more appropriate code that I should report?

Answer: It is appropriate to report code 20670 for arch bar removal because it is not considered an inclusive compo-nent of code 21453. Third-party payers may require that a modifier (eg, 58 or
78) be appended to code 21453 if the removal is per-formed within the global period of the initial surgery
