What 28110 covers
This procedure removes part of the fifth metatarsal head, commonly for a painful bunionette (tailor’s bunion) with lateral prominence and shoe-related pressure or irritation. A podiatrist or orthopedic foot-and-ankle surgeon typically performs it in an operating room or ambulatory surgery center. The operative work is a partial resection of the fifth metatarsal head, rather than removal of the entire metatarsal or correction by metatarsal osteotomy.
Select the code when the documented operation removes only part of the fifth metatarsal head. The operative report should identify the bone and side, describe the extent of resection, and support the indication. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in the same session, the highest-valued procedure is paid in full and the others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment is statutorily restricted; co-surgeons require supporting documentation, and team surgery is not permitted.

28110 billing questions
When is this code appropriate for a bunionette?
Use it when the surgeon partially removes the fifth metatarsal head. A bunionette diagnosis alone does not establish the procedure; the operative report must support the partial resection.
How does it differ from complete fifth metatarsal head removal?
This code represents partial removal of the fifth metatarsal head. Code 28115 is for complete excision of that head.
Does the 90-day global period include postoperative visits?
It includes the day-before preoperative visit and 90 days of related postoperative care.
How is bilateral surgery paid under the CMS rule?
When reported bilaterally with modifier 50, CMS pays this procedure at 150%.
Can an assistant surgeon or co-surgeon be reported?
Assistant-at-surgery payment is subject to a statutory restriction. Co-surgeons are paid only when supporting documentation is provided.
What happens when it is performed with another procedure in the same session?
Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and the other procedures are paid at 50%.
