ICD-10 Code H40.823 – Hypersecretion glaucoma, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H40.823 – Hypersecretion glaucoma, bilateral
What it is
H40.823 identifies glaucoma related to excessive aqueous humor production in both eyes. Use it when the record specifically documents hypersecretion glaucoma as the cause or type.
Clinical signs
Clinical features vary; refer to documentation. Common glaucoma findings may include optic nerve damage, visual field loss, and elevated intraocular pressure, but you should code only what is documented.
When to use this code
Use this code when the provider documents bilateral hypersecretion glaucoma. It may appear in ophthalmology notes, problem lists, or assessment/plan entries that clearly link the diagnosis to both eyes. If laterality is not stated, check documentation before coding.
Do not use for
Do not use H40.823 for other glaucoma types, such as open-angle, angle-closure, or secondary glaucoma unless hypersecretion glaucoma is specifically documented. If the record only says glaucoma, check documentation.
Coding tip
Verify both the glaucoma type and bilateral laterality in the provider note before assigning H40.823.
