Hypersecretion glaucoma, bilateral

This code signifies a specific type of secondary glaucoma affecting both eyes, characterized by an overproduction of aqueous humor rather than an obstruction of its outflow. This excess fluid leads to elevated intraocular pressure (IOP) and subsequent optic nerve damage.

Apply this code when documentation explicitly states "hypersecretion glaucoma" affecting both eyes. This diagnosis is typically made after ruling out other forms of glaucoma and identifying an underlying cause for increased aqueous production.

• Ensure documentation clearly specifies "bilateral" involvement; otherwise, use a unilateral code.
• Always code the underlying cause of the hypersecretion, if known, as a primary diagnosis.
• Distinguish from codes for open-angle or angle-closure glaucoma, which involve outflow issues.
