The CPT® Code 67318 refers to strabismus surgery involving any procedure on the superior oblique muscle of the eye. The superior oblique muscle plays a crucial role in eye movement and is located at the superolateral aspect of the globe. It passes through a specialized tendon known as the trochlea, which is situated at the medial or nasal side of the orbit, and ultimately attaches to the posterior aspect of the orbit. This code encompasses various surgical interventions targeting the superior oblique muscle, with the specific procedure performed being contingent upon the underlying condition being addressed. For instance, one notable surgical technique associated with this code is the Harada-Ito procedure, which is specifically designed to correct eye misalignment resulting from cranial nerve IV palsy. During this procedure, an incision is made in the conjunctiva directly over the superior oblique muscle, allowing access to the muscle and its tendon. The tendon is then split, and the anterior fibers are repositioned in an anterior and lateral direction before being reattached to the globe. Finally, the conjunctival incision is meticulously closed with sutures, ensuring proper healing and alignment of the eye.

The procedure associated with CPT® Code 67318 is indicated for various conditions that involve misalignment of the eye, particularly those affecting the superior oblique muscle. The following are specific indications for performing this surgery:
The surgical procedure associated with CPT® Code 67318 involves several critical steps to effectively address the condition affecting the superior oblique muscle. The following outlines the procedural steps:
Post-procedure care following strabismus surgery involving the superior oblique muscle is essential for optimal recovery. Patients are typically monitored for any immediate complications following the surgery. It is common for patients to experience some degree of discomfort, swelling, or redness in the eye, which can be managed with prescribed medications. Follow-up appointments are crucial to assess the alignment of the eyes and the overall healing process. Patients may also receive specific instructions regarding activity restrictions, eye care, and the use of any prescribed eye drops or medications to prevent infection and promote healing. The expected recovery time can vary based on the individual and the complexity of the procedure, but most patients can anticipate gradual improvement in eye alignment and function over the weeks following surgery.

| 50 | Bilateral procedure: unless otherwise identified in the listings, bilateral procedures that are performed at the same session, should be identified by adding modifier 50 to the appropriate 5 digit code. note: this modifier should not be appended to designated "add-on" codes (see appendix d). | 51 | Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d). | 62 | Two surgeons: when 2 surgeons work together as primary surgeons performing distinct part(s) of a procedure, each surgeon should report his/her distinct operative work by adding modifier 62 to the procedure code and any associated add-on code(s) for that procedure as long as both surgeons continue to work together as primary surgeons. each surgeon should report the co-surgery once using the same procedure code. if additional procedure(s) (including add-on procedure(s) are performed during the same surgical session, separate code(s) may also be reported with modifier 62 added. note: if a co-surgeon acts as an assistant in the performance of additional procedure(s), other than those reported with the modifier 62, during the same surgical session, those services may be reported using separate procedure code(s) with modifier 80 or modifier 82 added, as appropriate. | 79 | Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.) | 80 | Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s). | GC | This service has been performed in part by a resident under the direction of a teaching physician | LT | Left side (used to identify procedures performed on the left side of the body) | RT | Right side (used to identify procedures performed on the right side of the body) | SG | Ambulatory surgical center (asc) facility service |
