Revision Of A Glaucoma Drainage Implant

Maryland rates for HCPCS 66184

Surgery to adjust or repair an implanted glaucoma drainage device — a small plate and tube that carries fluid out of the eye to lower pressure. The tube may be repositioned, unblocked, shortened, or re-secured so drainage works properly again. The device stays in place rather than being exchanged for a new one.
