What 28307 covers

A surgeon or podiatrist cuts and repositions a metatarsal and uses autograft—bone taken from the same patient—to support the correction or reconstruction. The procedure may address a metatarsal deformity requiring a change in bone alignment or length. The graft harvest is included in this service. These operations are generally performed in an operating room, including a hospital outpatient department or ambulatory surgery center.

Choose this code when the operative report supports both a metatarsal osteotomy and use of autograft. Document the metatarsal treated, the reason and manner of the osteotomy, and the graft’s source and use. The service has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same 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 requires documented medical necessity; co-surgeons and team surgery are not permitted.

28307 billing questions

When should this code be selected instead of a metatarsal osteotomy code without graft?

Use this code when the metatarsal osteotomy includes autograft. A metatarsal osteotomy without autograft is represented by a different code in the family.

Is harvesting the patient’s bone reported separately?

No. The graft harvest is included when this code is used.

What documentation supports reporting this service?

The operative report should identify the metatarsal, describe the osteotomy and its purpose, and document the patient’s own bone graft and how it was used.

How does the 90-day global period affect postoperative claims?

The day-before preoperative visit and 90 days of related postoperative care are included in the global period.

How is bilateral performance handled?

For a bilateral procedure reported with modifier 50, CMS pays 150%.

Can an assistant or co-surgeon be reported?

Assistant-at-surgery payment requires documentation of medical necessity. Co-surgeons and team surgery are 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.
