What 65810 covers

This procedure removes vitreous from the eye’s anterior chamber through an anterior approach. It may be needed when vitreous prolapses forward after cataract surgery and threatens to obstruct the pupil or contact the cornea. Ophthalmologists typically perform it in an operating room or other surgical setting, using an approach suited to the location and extent of vitreous in the anterior chamber.

Choose 65810 when vitreous is removed, rather than aqueous fluid or blood; the operative note should identify the material, its location, the approach, and the clinical reason for removal. Medicare assigns a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. When other procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are paid at 50%. For bilateral reporting with modifier 50, payment is at 150%. Medicare does not pay assistant-at-surgery services for this procedure, and co-surgeon and team-surgery billing 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.
