A reconstructive surgical procedure involving an osteotomy of the midtarsal or tarsal bones to correct a deformity in the foot and ankle region. The service is listed under Musculoskeletal System Surgical Procedures. Payment for the surgeon (suffix A) is a flat fee, while services for the assistant (suffix B) and anaesthesiologist (suffix C) are calculated using a unit-based system. This service is assigned 6 base units for an assistant and 7 base units for anaesthesia.

When to Use

Use R277 for corrective osteotomies of the tarsal or midtarsal bones, such as a calcaneal osteotomy or a midfoot realignment procedure.
Select R277 when performing a formal bone cut and realignment of the tarsal bones, distinguishing it from simple soft tissue releases or arthrodesis procedures like R337 or R338.

Common Pitfalls

Billing R277 as a primary procedure when it is incidental to a more comprehensive foot reconstruction; ensure the procedure is distinct and not bundled under a global fee for complex foot surgeries.
Failing to append E596 for additional osteotomies performed during the same operative session, which leads to under-billing for multi-planar or multi-bone corrections.

Billing Tips

Always document the specific tarsal bones involved to justify the use of R277 over other musculoskeletal codes, as auditors specifically look for the anatomical site of the osteotomy.
Ensure the assistant (suffix B) and anaesthesiologist (suffix C) claims correctly reflect the 6 and 7 base units respectively, as these are frequently missed in automated billing software.
