What 67312 covers
An ophthalmic surgeon uses recession, which moves a muscle’s attachment to weaken its pull, or resection, which shortens the muscle to strengthen its pull. This code covers work on two horizontal extraocular muscles for strabismus, or misalignment of the eyes. The service is commonly performed in an operating room, with the operative report identifying the muscles treated and the eye or eyes involved.
Choose the code by the number and orientation of the muscles treated, not by the degree of misalignment. Documentation should support the two horizontal muscles and the recession or resection performed. The 90-day global period includes 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%. Modifier 50 indicates bilateral surgery, paid at 150%. Medicare does not pay an assistant at surgery; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
