Answer: How you code this condition depends on whether other symptoms are present.
 
Plateau iris is characterized by the iris having a flat appearance, rather than being forwardly convex. It is manifested by an abnormal iris and ciliary body. The patient with the chronic form of this condition slowly develops high intraocular pressure and visual field loss, but no pain. At first, the iris is still normal, but the ciliary body is abnormally anterior, and this changes the configuration of the iris as it pushes the peripheral part of the iris up into the angle.
 
Code the latter type without other symptoms as plateau iris configuration (365.02, Anatomical narrow angle) or syndrome (365.41, Glaucoma associated with chamber angle anomalies). However, if the intraocular pressure (IOP) is elevated or if the plateau iris is a form of angle-closure glaucoma, you should use 365.2x (Primary angle-closure glaucoma).
