CPT® Code 65290

The procedure described by CPT® Code 65290 involves the repair of a wound affecting the extraocular muscle, tendon, and/or Tenon's capsule. This surgical intervention is performed using conventional sutures to restore the integrity of the affected structures. The eye is meticulously examined, often utilizing a slit lamp or operating microscope, to assess the extent of the wound and any potential damage to surrounding ocular structures. The eyeball is supported within the orbit and is encased by Tenon's capsule, a fibrous tissue that extends from the optic nerve entrance to the corneal limbus, firmly attaching to the conjunctiva. The extraocular muscles, which include the horizontal rectus, vertical rectus, and oblique muscles, are connected to the sclera (the white part of the eye) via broad, thin tendons. A wound on the cornea or sclera can compromise the structural integrity of these muscles, tendons, and Tenon's capsule. During the procedure, the surgeon identifies the ends of any transected muscle or tendon, reapproximates them, and secures them with sutures. Additionally, Tenon's capsule is carefully dissected to remove any foreign bodies or trapped tissue, which is then closed with sutures. At the conclusion of the surgery, antibiotics may be administered directly into the conjunctiva or other areas of the eye, and the eye is protected with a sterile dressing and an eye shield to promote healing and prevent infection.
