What 15823 covers

This procedure removes excess upper eyelid skin that hangs over or weighs down the lid. Ophthalmologists, oculoplastic surgeons, and plastic surgeons commonly perform it for patients with functional concerns such as restricted superior vision from drooping eyelid skin. It may be performed in an office-based surgical setting or an operating room, depending on the case and setting.

Choose this code when the record supports excess upper-lid skin affecting function, rather than an upper eyelid procedure without that feature. Document the eyelid findings and the functional impact; examination findings and visual-field information may support medical necessity. Medicare assigns a 90-day global period, including the day-before preoperative visit and related postoperative care. For bilateral surgery, modifier 50 is paid at 150%. When multiple procedures occur in one session, the highest-valued procedure is paid in full and others at 50%. Medicare does not pay an assistant at surgery; co-surgeons and team surgery are not permitted.

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.
