Intermittent angle-closure glaucoma, left eye

This code signifies a form of glaucoma characterized by episodic closure of the anterior chamber angle in the left eye, leading to transient increases in intraocular pressure. This intermittent closure obstructs aqueous humor outflow, causing symptoms such as eye pain, blurred vision, and halos around lights during acute attacks.

Use this code when documentation specifies intermittent angle-closure glaucoma affecting the left eye. This diagnosis is typically supported by ophthalmological examination findings, including gonioscopy showing a narrow or occludable angle, and patient-reported symptoms consistent with acute angle-closure episodes.

• Ensure laterality is accurately documented; this code is specific to the left eye.
• Distinguish from chronic or acute angle-closure glaucoma, which have different codes.
• Look for terms like "intermittent," "episodic," or "recurrent" angle closure in the patient's record.
