Clinical & Coding Specifications
Clinical Context
A 56-year-old female presents to a facial plastic surgery clinic concerned about persistent bulging and excess skin beneath both lower eyelids that produce a tired appearance and intermittent tearing. Conservative measures have failed to improve the cosmetic deformity. After preoperative evaluation, including history, focused ocular examination, and discussion of risks and benefits, the patient is scheduled for lower eyelid blepharoplasty under monitored anesthesia care. The procedural workflow includes preoperative marking in the clinic, informed consent, surgical trimming of excess skin and protruding orbital fat pads via a transcutaneous subciliary incision, hemostasis, layered closure, and postoperative instructions. Postoperative visits at 1 week and 4–6 weeks assess wound healing, eyelid position, and aesthetic outcome. Typical payors for authorization and claims include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, BUCA, and Medicare.
