ICD-10 Code H40.82 – Hypersecretion Glaucoma (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H40.82 – Hypersecretion glaucoma
What it is
H40.82 identifies glaucoma associated with excessive aqueous humor production, leading to elevated intraocular pressure. Use it when the record specifically documents hypersecretion glaucoma.
Clinical signs
Clinical features vary; refer to documentation. Typical glaucoma findings may include optic nerve damage, visual field loss, and increased intraocular pressure, but you should code only what is documented.
When to use this code
Use H40.82 when the clinician states hypersecretion glaucoma as the diagnosis, or documents glaucoma due to overproduction of aqueous humor. It may appear in ophthalmology notes, problem lists, or discharge summaries. If the cause is unclear, check documentation.
Do not use for
Do not use this code for other glaucoma types, such as open-angle, angle-closure, or steroid-induced glaucoma, unless hypersecretion is specifically documented. Do not assign it based on elevated pressure alone.
Coding tip
Code the documented glaucoma type exactly and query the provider when the record does not clearly link glaucoma to hypersecretion.
