Question: What is the appropriate code to report corrective surgery involving the removal of the medial eminence (bunion), removal of dorsal osteophytes from the metatarsal head, and removal of an osteophytic rim from the base of the proximal phalanx? (Dorsal closing wedge and medial closing wedge osteotomies of the proximal phalanx with fixation using a single screw were also performed.)

Answer:
If both osteotomies were performed on the phalanx (a bidirectional osteotomy) it would be appropriate to report code 28298 (Correction, hallux valgus [bunion], with or without sesamoidectomy; by phalanx osteotomy).
If one of the osteotomies was performed on the phalanx and the other on the metatarsal, it would be appropriate to report code 28299 (Correction, hallux valgus [bunion], with or without sesamoidectomy; by double osteotomy).
The resection of the osteophytes and the medial eminence would be included in either code.
