Strabismus surgery
About 67318: Superior oblique muscle strabismus surgery
Reports strabismus surgery that changes the superior oblique muscle’s tension or position to address vertical or torsional eye misalignment.
An ophthalmic surgeon uses this code for a recession or resection procedure involving the superior oblique muscle as part of strabismus surgery. The operation changes the muscle’s position or effective tension to address misalignment, such as a vertical or torsional deviation associated with superior oblique dysfunction. These procedures are typically performed in an operating room, often in a facility setting.
Select this code when the operative report identifies the superior oblique muscle and documents the procedure performed; codes for other extraocular muscles distinguish different muscles or muscle counts. The code 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 others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Medicare payment for an assistant at surgery is restricted; co-surgeons are paid only with supporting documentation, and team surgery is not permitted.
