Cataract Surgery With Glaucoma Drainage Device

Illinois rates for HCPCS 66991

A surgeon removes a cloudy natural lens from the eye (a cataract) and replaces it with an artificial lens, and in the same operation implants a small device that helps drain fluid from the eye to manage glaucoma. Combining these two procedures in one operation treats both the cataract and glaucoma together. This is used when a patient has both conditions and can benefit from addressing them at the same time.
