Sesamoidectomy

“Has anyone had CIGNA, Tufts, UHC reject CPT code 28310 (Akin osteotomy) as a separate and billable code with a Lapidus arthrodesis/hallux valgus correction with bunionectomy (CPT 28297)? I did appeal with CIGNA and was told that the nurse-coder looked at my appeal and related to me that according to the NCCI Edits, the Akin osteotomy is “part and parcel” included with a Lapidus arthrodesis/ bunionectomy. What is the next step?”
