CPT® Code 67880

The procedure described by CPT® Code 67880 involves the construction of intermarginal adhesions through median tarsorrhaphy or canthorrhaphy. The eyelids are complex structures composed of several layers, including the skin, orbicularis muscle, tarsus, and conjunctiva. The tarsal plates, or tarsi, are made of dense fibrous tissue that provides the eyelids with their distinct shapes; the upper eyelid is crescent-shaped, while the lower eyelid is rectangular. Median tarsorrhaphy is a surgical technique that creates adhesions between the upper and lower eyelid margins at the midline, primarily aimed at protecting the cornea from exposure or injury. In contrast, canthorrhaphy involves forming adhesions at the corners of the eyelids, known as the medial and lateral canthus. The procedure begins with the excision of a narrow strip of skin from both the upper and lower eyelids at the midline, with incisions made just posterior to the eyelashes. The resulting surgical wounds are then approximated and secured using interrupted sutures to ensure proper healing and alignment. Canthorrhaphy follows a similar approach, where skin is removed from the upper and lower eyelids at either the medial or lateral canthus, and the wounds are also approximated and sutured. This surgical intervention is crucial for maintaining eyelid function and protecting the ocular surface.
