What 28297 covers

Code 28297 describes operative correction of a bunion deformity that includes fusion of the joint between the first metatarsal and medial cuneiform. This Lapidus-type approach is used when the surgeon selects fusion at that joint as part of the hallux valgus correction. The operation may include removal of the prominent bone and sesamoidectomy when performed. It is typically done by an orthopedic foot-and-ankle surgeon or podiatric surgeon in a hospital operating room or ambulatory surgery center.

Select this code when the documented correction includes the first tarsometatarsal joint fusion, rather than a metatarsal or phalangeal osteotomy alone. Record the deformity, operative work, joint fused, laterality, and any sesamoidectomy. The 90-day global includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and others at 50%. Modifier 50 identifies bilateral surgery and payment is 150%. Assistant-at-surgery payment may be available; co-surgeons require supporting documentation. Team surgery is not permitted.

28297 billing questions

When should 28297 be selected instead of a hallux valgus osteotomy code?

Use 28297 when the correction includes fusion of the first metatarsal–medial cuneiform joint. Osteotomy codes apply when the documented correction uses the specified metatarsal or phalangeal bone cut instead.

Is the sesamoidectomy separately reported?

Sesamoidectomy is included in 28297 when performed as part of the hallux valgus correction. The code also encompasses the first-joint fusion that distinguishes this procedure.

How is bilateral surgery reported?

For bilateral performance, report modifier 50; CMS payment is 150%.

What postoperative care is included in the global period?

The 90-day global includes the day-before preoperative visit and 90 days of related postoperative care.

Can an assistant or co-surgeon be paid?

Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation.

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.
