About 29905: Subtalar arthroscopic coalition excision
Report this service when a surgeon arthroscopically excises a symptomatic tarsal coalition within the subtalar joint.
This code describes arthroscopic excision of a tarsal coalition in the subtalar joint, the articulation between the talus and calcaneus. An orthopedic surgeon or podiatric surgeon may perform the procedure for a symptomatic coalition, such as one associated with restricted hindfoot motion or pain. It is generally performed in a hospital outpatient department or ambulatory surgery center, rather than an office setting.
Select the code when the operative report supports arthroscopic excision of the coalition, not simply diagnostic inspection or another subtalar procedure. Documentation should identify the joint, coalition treated, arthroscopic work, and any other procedures performed during the session. The service has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard reduction. Bilateral reporting with modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeons and team surgery are not permitted.
