Hello depends on where the osteotomies were. For 28295 it would be the proximal metatarsal (above toe) and 28298 for the proximal phalanx (toe). If both were done with bunionectomy code would be 28299 and nothing else.
Every autumn, the American Medical Association's (AMA) Current Procedural Terminology (CPT) book is updated with changes for the next year. In 2016, minimal changes were made, possibly due to the implementation of the International Classification of Diseases, 10th edition (ICD-10) and a...

QUESTION 8
A patient underwent an Austin-Akin osteotomy at our facility and we need assistance in the correct code assignment for this procedure. The Austin-Akin procedure has been defined as a double osteotomy and is usually performed on the proximal phalanx and distal metatarsal or double osteotomy of the metatarsal. We currently report CPT code 28299, Correction, hallux valgus (bunion), with or without sesamoidectomy; by double osteotomy, for this procedure. Recently, an Austin-Akin osteotomy was performed and the physician documented the medial phalanx as opposed to the proximal phalanx. Would this still be coded as an Austin-Akin procedure since it was performed on the medial phalanx instead of the proximal phalanx? Any guidance you can provide would be greatly appreciated.
ANSWER
Report CPT code 28299, Correction, hallux valgus (bunion), with or without sesamoidectomy; by double osteotomy, for the Austin-Akin osteotomy performed on the medial phalanx. The Akin osteotomy portion of the procedure is a medial closing wedge osteotomy performed at the level of the proximal phalangeal base.
