Primary angle closure without glaucoma damage, bilateral

This code signifies a condition where the drainage angle of the eye is anatomically narrow or closed, predisposing the patient to acute angle-closure glaucoma, but without any evidence of optic nerve damage or visual field loss typically associated with glaucoma. It represents a high-risk state for glaucoma development.

Apply this code when documentation confirms primary angle closure in both eyes, but specifically states that no glaucomatous optic neuropathy or visual field defects are present. This diagnosis is often made during routine ophthalmic examinations or when evaluating patients with symptoms suggestive of intermittent angle closure.

• Ensure documentation explicitly states "without glaucoma damage" for both eyes.
• Do not use this code if there is any evidence of optic nerve damage or visual field loss; instead, consider codes for primary angle-closure glaucoma.
• This code is often used in conjunction with codes for underlying causes or associated conditions, if applicable.
