What 66985 covers

An ophthalmologist uses this service to place an intraocular lens in an eye that lacks its natural lens, typically after cataract extraction or other prior lens removal. It represents a later implant procedure, rather than lens placement during the same operation as cataract removal. The procedure is commonly performed in an operating room or ambulatory surgery center; the surgeon documents the eye’s lens status and the method used to position and secure the implant.

Report the code for the secondary implant, with laterality supported in the operative record. The 90-day global period includes the day-before preoperative visit and related postoperative care during that period. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%. For bilateral reporting with modifier 50, CMS pays 150%. Assistant-at-surgery payment is restricted by statute; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
