What 28310 covers

This procedure uses a bone cut in the proximal phalanx of the great toe to change its alignment or length. Foot and ankle orthopedic surgeons and podiatrists may perform it for a phalangeal deformity, such as hallux valgus interphalangeus, or as an Akin-type correction during hallux valgus surgery. It is performed in an operating room or, in selected cases, an office-based procedure setting. It addresses the toe bone, not the first metatarsal.

Report the code when the operative work is an osteotomy of the great toe’s proximal phalanx. The operative report should identify the bone, the deformity and the correction performed, and clarify whether the osteotomy is part of a broader hallux valgus procedure. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in one session, the highest-valued procedure is paid in full and others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment is restricted; co-surgeons require supporting documentation, and team surgery is not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

28310 billing questions

How is this different from 28312?

This code is for an osteotomy of the proximal phalanx of the great toe. Code 28312 covers phalanges of other toes.

When should 28298 be considered instead?

Code 28298 represents hallux valgus correction that includes a proximal phalanx osteotomy. Use it when the documented work is that combined correction, rather than reporting the same osteotomy separately as 28310.

Can this be reported with a first metatarsal osteotomy?

The procedures address different bones: 28310 treats the great toe’s proximal phalanx, while codes such as 28306 treat a metatarsal. The operative report should support each distinct procedure reported.

What documentation supports reporting this code?

Document the great-toe proximal phalanx, the deformity being corrected, and the osteotomy and resulting change in alignment or length. Clarify whether the work is included in a broader hallux valgus correction.

How is bilateral surgery paid?

CMS lists this as a bilateral procedure: when both sides are performed and reported with modifier 50, payment is at 150%.

Can an assistant or co-surgeon be reported?

Assistant-at-surgery payment is restricted for this code. Co-surgeons are paid only with supporting documentation; team surgery is not permitted.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
