Glaucoma surgery
About 66172: Trabeculectomy in a scarred eye
Reports glaucoma filtering surgery performed in an eye with scarring from prior ocular surgery or trauma that affects the operative setting.
An ophthalmic surgeon performs a filtering operation to lower intraocular pressure by creating a pathway for aqueous humor to leave the eye and collect beneath the conjunctiva. This code applies when scarring from earlier ocular surgery or trauma affects the operative setting. The procedure is commonly performed in an operating room for a patient with glaucoma who needs pressure-lowering surgery.
Document the glaucoma indication, the prior surgery or trauma, and the resulting scarring that supports choosing this code over 66170. The service has a 90-day global period: the day-before preoperative visit and related postoperative care during that period are included. For bilateral surgery, modifier 50 is paid at 150%. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and others at 50%. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
