What 28740 covers

An orthopedic or podiatric surgeon fuses one midtarsal or tarsometatarsal joint to reduce painful motion and stabilize the foot. The operation typically prepares the joint surfaces for bone healing and holds the bones in position with fixation. Common clinical settings include operative treatment of arthritic or unstable midfoot joints, including a single tarsometatarsal joint. The service is generally performed in a hospital or ambulatory surgery center.

Report this code when the operative documentation supports fusion of one joint in the midtarsal or tarsometatarsal region. A fusion involving multiple joints or a transverse fusion is distinguished from this single-joint service. The procedure has a 90-day global period, which includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 identifies a bilateral procedure, paid at 150%. Assistant-at-surgery payment may be available; co-surgeons require 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.

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.
