What 15820 covers

This procedure surgically reshapes the lower eyelid, commonly to address loose or redundant skin and age-related fullness. It is typically performed by an ophthalmic plastic surgeon, plastic surgeon, or other qualified physician in an outpatient operating facility. The operative note should identify the lower eyelid treated and describe the findings and work performed.

Select this code for lower-lid surgery without the extensive herniated fat-pad feature that distinguishes 15821. Document laterality, the clinical indication, relevant skin or contour findings, and the procedure’s extent. For bilateral surgery, modifier 50 is paid at 150%. 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 period 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.

What postoperative care is included?

The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
