What 28289 covers

This operation treats hallux rigidus, a painful, stiff first metatarsophalangeal joint, by removing limiting bone and diseased tissue and releasing the joint capsule. It is typically performed by an orthopedic foot and ankle surgeon or podiatric surgeon in an operating room or ambulatory surgery setting. The defining distinction from the related implant procedure is that no implant is used.

Report the service when the operative note supports the hallux rigidus correction and its components at the first metatarsophalangeal joint. The code has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery services may be paid; co-surgeon payment requires 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.

Both address hallux rigidus at the first metatarsophalangeal joint. Use 28289 for the correction without an implant; 28291 is the implant procedure.

What should the operative note support?

Document hallux rigidus, the affected first metatarsophalangeal joint, the correction performed, and whether an implant was used. The note should support the reported service rather than only describing a general bunion or toe procedure.

Does the code include postoperative visits?

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

How is bilateral surgery reported?

When the procedure is performed bilaterally, modifier 50 applies, and CMS pays the bilateral procedure at 150%.

How are other procedures in the same session paid?

Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and the other procedures are paid at 50%.

Can an assistant or co-surgeon be reported?

Assistant-at-surgery services may be paid. Co-surgeon payment requires 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.
