Ophthalmic surgery
About 65815: Anterior chamber drainage with replacement
Ophthalmologists report this procedure when they drain aqueous from the eye’s anterior chamber and refill it with air, gas, or liquid.
This procedure is an anterior chamber paracentesis that removes aqueous and replaces it with air, another gas, or fluid. An ophthalmologist may perform it as an anterior chamber washout, including for a significant hyphema requiring evacuation and chamber replacement. It is a surgical service, commonly furnished in an operating room or other procedural setting; the operative note should identify the chamber drainage and the replacement material.
Select this code when both drainage and replacement are performed. A diagnostic aspiration or medication injection alone, or drainage without replacement, points to a different code in the family. Documentation should describe the reason for the procedure, the fluid or material removed, and what was used to refill the chamber. Medicare assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and other procedures at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment is restricted; co-surgeons and team surgery are not permitted.
