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.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

15821 billing questions

How does 15821 differ from 15820?

Use 15821 when the lower-lid blepharoplasty addresses pronounced prolapse of orbital fat pads. Use 15820 for lower-lid blepharoplasty without that degree of fat-pad involvement.

Can 15820 also be reported for the same lower eyelid?

Do not separately report 15820 for the same lower-lid blepharoplasty represented by 15821. Document the fat-pad findings and the operative work supporting 15821.

How should bilateral lower-lid surgery be reported?

Report the bilateral procedure with modifier 50. CMS pays it at 150% of the unilateral payment.

What happens when another procedure is performed in the same session?

CMS pays the highest-valued procedure in full and other procedures at 50% under the standard multiple procedure reduction.

What postoperative care is included in the global period?

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

When is assistant-at-surgery payment allowed?

CMS pays an assistant at surgery only when medical necessity is documented. Co-surgeons and team surgery are not permitted for this code.

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.
