What 28705 covers

Pantalar arthrodesis fuses the ankle and hindfoot joints—the tibiotalar, subtalar, talonavicular, and calcaneocuboid articulations—into a stable construct. A foot-and-ankle orthopedic surgeon typically performs this extensive operation for severe painful arthritis, deformity, or instability involving the joint complex, including selected post-traumatic or neuromuscular cases.

Report the service when the operative documentation supports fusion of the ankle and the hindfoot articulations, rather than a more limited fusion. Document the treated joints, indication, and laterality. The procedure has a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. For multiple procedures 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.

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.
