CPT® Code 67966

Excision and repair of eyelid, involving lid margin, tarsus, conjunctiva, canthus, or full thickness, may include preparation for skin graft or pedicle flap with adjacent tissue transfer or rearrangement; over one-fourth of lid margin

The CPT® Code 67966 refers to a surgical procedure involving the excision and repair of the eyelid, specifically when the procedure encompasses the lid margin, tarsus, conjunctiva, canthus, or the full thickness of the eyelid. This procedure is typically performed to remove a lesion that may be malignant, such as basal cell carcinoma, squamous cell carcinoma, sebaceous carcinoma, or melanoma. The excision is conducted with the intent to remove not only the lesion but also a margin of healthy tissue surrounding it to ensure complete removal of cancerous cells. Following the excision, the surgical defect is repaired, which may involve the use of a skin graft or a pedicle flap, as well as adjacent tissue transfer or rearrangement. The extent of the excision is significant, as it involves over one-fourth of the lid margin, necessitating careful planning and execution to achieve optimal cosmetic and functional outcomes. The procedure may also require a pathological examination of the excised tissue to confirm that the margins are clear of malignancy; if they are not, further excision may be necessary. The reconstruction technique varies depending on whether the upper or lower eyelid is being addressed and the specific location of the defect on the eyelid itself, whether it be medial, central, or lateral. This complexity underscores the importance of skilled surgical intervention in managing eyelid lesions effectively.
