About 28725: Subtalar joint fusion
Reports surgical fusion of the subtalar joint, commonly performed for painful hindfoot arthritis or deformity when the talocalcaneal joint is treated.
An orthopedic foot and ankle surgeon fuses the joint between the talus and calcaneus, typically to address painful subtalar arthritis, post-traumatic joint damage, or hindfoot deformity. The operation involves preparing the joint surfaces and stabilizing the bones in the intended alignment; it is commonly performed in a hospital or ambulatory surgical setting. The operative report should identify the subtalar joint and describe the fusion performed.
Choose this code when the subtalar joint is fused, rather than a broader construct that includes other hindfoot joints. The 90-day global period includes the day-before preoperative visit and related postoperative care during the global period. 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% multiple-procedure reduction. Bilateral reporting with modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeons are paid only with supporting documentation, and team surgery is not permitted.

28725 billing questions
When is 28725 appropriate instead of a triple arthrodesis code?
Use 28725 when the subtalar joint is fused. A triple arthrodesis includes additional hindfoot joints, so select the code that reflects the joints actually fused.
Does the 90-day global period include routine postoperative care?
Yes. The global period includes the day-before preoperative visit and 90 days of related postoperative care.
How is bilateral subtalar fusion reported?
CMS identifies this as a bilateral procedure reported with modifier 50 and paid at 150%.
Can an assistant or co-surgeon be reported?
An assistant at surgery may be paid. Co-surgeons are paid only when supporting documentation is provided; team surgery is not permitted.
What documentation supports selecting this code?
Document the subtalar joint treated, the clinical reason for fusion, and the operative work performed. The note should make clear whether the fusion was limited to that joint or included other hindfoot joints.
What happens when another procedure is performed in the same session?
Under the standard multiple-procedure rule, the highest-valued procedure is paid in full and other procedures are paid at 50%.
