What 28735 covers

This code covers fusion of multiple joints in the midfoot, or a transverse fusion across the midfoot, when the operation also includes an osteotomy. Foot and ankle orthopedic surgeons and podiatric surgeons may perform it for conditions such as painful midfoot arthritis or deformity requiring both joint fusion and bony realignment. The operative report should identify the joints fused and describe the osteotomy and its role in the correction.

Select this code when the fusion involves multiple or transverse midtarsal or tarsometatarsal joints and an osteotomy is performed; a single-joint fusion or a multiple-joint fusion without osteotomy points to a different code. The osteotomy is part of the service represented here. Medicare assigns a 90-day global period, including the day-before preoperative visit and related postoperative care. When multiple procedures are performed in one 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 may be available; 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.

28735 billing questions

How does this differ from 28730?

Both address multiple or transverse midfoot fusion. This code includes an osteotomy; 28730 is the corresponding fusion without an osteotomy.

Can the osteotomy be billed separately?

The osteotomy is included in this code’s service when performed as part of the midfoot fusion and correction.

When is 28740 a better choice?

Use 28740 for a fusion of a single midtarsal or tarsometatarsal joint, rather than multiple joints or a transverse fusion.

What documentation supports selecting this code?

Document the specific midtarsal or tarsometatarsal joints fused and the osteotomy performed, including its role in correcting alignment or deformity.

What payment rules affect the claim?

Medicare applies a 90-day global period and standard multiple-procedure reduction for procedures in the same session. Modifier 50 applies to bilateral procedures.

Can an assistant or co-surgeon be reported?

Assistant-at-surgery payment may be available. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
