Plateau iris syndrome (post-iridectomy) (postprocedural)

This code represents a specific type of secondary angle-closure glaucoma characterized by a normal anterior chamber depth but a narrow or closed angle due to the ciliary body being positioned anteriorly, pushing the peripheral iris forward. It typically occurs after a peripheral iridotomy or iridectomy, which failed to resolve the angle closure.

Use this code when documentation explicitly states "plateau iris syndrome" occurring after an iridectomy or other related procedure. This diagnosis is often made after gonioscopy reveals a characteristic "double hump" sign and ultrasound biomicroscopy (UBM) confirms the anteriorly rotated ciliary body.

• Ensure documentation specifies "post-iridectomy" or "postprocedural" to support the use of this specific code.
• Do not confuse with primary plateau iris configuration, which is congenital and not postprocedural.
• Consider sequencing this code with a code for the underlying glaucoma if still present and being treated.
