CPT® Code 15821

Blepharoplasty, lower eyelid with extensive herniated fat pad, as described by CPT® Code 15821, is a surgical procedure aimed at correcting aesthetic and functional issues associated with the lower eyelids. This procedure specifically addresses the presence of herniated fat pads, which can contribute to a puffy appearance under the eyes, often leading to a tired or aged look. The surgery involves making an incision in the conjunctiva of the lower eyelid to access the underlying fat pad. The procedure may also involve severing the tendon on the lateral aspect of the eyelid to enhance visibility and access to the fat pad. The surgeon dissects the herniated fat pad from surrounding tissues, allowing for its removal or repositioning. A common technique used in this procedure is the creation of a subperiosteal tunnel, which facilitates the transposition of the fat to the tear trough area over the cheekbone, thereby improving the contour and appearance of the lower eyelid. The procedure concludes with the excision of a wedge of eyelid tissue to tighten the lower lid, followed by securing the new tendon to the periosteum of the orbital rim and closing the incision with running sutures. This comprehensive approach not only enhances the aesthetic outcome but also addresses any functional impairments related to the lower eyelid structure.
