Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 15821 covers

This procedure reshapes the lower eyelid when prominent orbital fat pads create under-eye bulging. The surgeon may remove or reposition protruding fat and address redundant skin as part of the lid contouring. Oculoplastic, plastic, or facial plastic surgeons commonly perform it in an ambulatory surgery center or hospital, and sometimes in an office-based operating setting. The operative note should identify the lower lid treated, describe the extent of fat prolapse, and document the work performed and the clinical indication.

Select this code when the lower-lid operation involves substantial fat-pad prolapse; use 15820 for lower-lid blepharoplasty without that extent of fat involvement. For both eyelids, CMS pays modifier 50 at 150% of the unilateral payment. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and the others at 50%. The 90-day global includes the day-before preoperative visit and 90 days of related postoperative care. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.
