Intermittent angle-closure glaucoma, bilateral

This code signifies a form of glaucoma characterized by episodic closure of the anterior chamber angle, leading to transient increases in intraocular pressure, affecting both eyes. This intermittent closure obstructs aqueous humor outflow, causing symptoms like ocular pain, blurred vision, and halos around lights.

Apply this code when documentation explicitly states "intermittent angle-closure glaucoma" affecting both eyes. This diagnosis is typically made based on gonioscopy findings showing an occludable angle and tonometry demonstrating fluctuating or elevated intraocular pressure during symptomatic episodes.

• Ensure documentation specifies "intermittent" and "bilateral" to support this code.
• Distinguish from acute or chronic angle-closure glaucoma, which have different codes.
• Code any associated complications, such as visual field defects, separately.
