What 67110 covers
A vitreoretinal ophthalmologist typically performs pneumatic retinopexy for a selected retinal detachment. The surgeon injects air or another gas into the eye to press the detached retina back against the eye wall; retinal breaks may also be treated to help seal them. Subretinal fluid drainage, when performed as part of this repair, is included. The procedure is commonly performed in an office or surgical facility, with follow-up positioning instructions to keep the gas bubble against the treated area.
Report 67110 when the repair uses gas injection, rather than a scleral buckle or a vitrectomy-based approach. The operative note should identify the detachment, gas injection, and any drainage or retinal-break treatment performed. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures 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.
