Foot surgery

About 28312: Lesser toe proximal phalanx osteotomy

Reports surgical reshaping of a lesser toe’s proximal phalanx to correct shortening, angular alignment, or rotation when an osseous correction is performed.

This procedure reshapes the proximal phalanx of a toe other than the great toe to correct a bony alignment problem, such as angular or rotational deformity. An orthopedic foot and ankle surgeon or podiatric surgeon typically performs it in an operating room, often as part of forefoot reconstruction. The operative report should identify the treated lesser toe, the phalanx addressed, the deformity, and the osteotomy and correction performed.

Report this code for the proximal-phalanx osteotomy, not merely because a toe deformity was treated. The 90-day global period includes the day-before preoperative visit and related postoperative care for 90 days. When multiple procedures are performed in the same session, Medicare pays the highest-valued procedure in full and reduces the others to 50%. Modifier 50 is inappropriate for this code. Medicare does not pay an assistant at surgery; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

For 28312 in Delaware, the physician’s office rate is $589.18 and the facility-setting rate is $343.00: a difference of $246.18.

28312 billing questions

When is this code appropriate instead of 28310?

Use 28312 for a proximal-phalanx osteotomy of a toe other than the great toe. Code 28310 is for the great toe’s proximal phalanx.

Does a hammertoe diagnosis alone support this code?

No. Documentation should establish that the surgeon performed a proximal-phalanx osteotomy to correct the lesser toe’s bony alignment. A hammertoe procedure without that osteotomy does not establish the service.

Can this be reported with a metatarsal osteotomy?

It may be reported with a metatarsal osteotomy when both distinct bony corrections are performed and documented. Same-session procedures are subject to Medicare’s multiple procedure reduction.

Can modifier 50 be used when both feet are treated?

No. CMS identifies bilateral adjustment as inappropriate for this code. Follow the applicable reporting instructions for services performed on separate toes or feet.

How does the global period affect postoperative visits?

The 90-day global period includes the day-before preoperative visit and related postoperative care during the 90 days after surgery.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
