ICD-10 Code H40.051 – Ocular hypertension, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H40.051 – Ocular hypertension, right eye
What it is
H40.051 identifies elevated intraocular pressure in the right eye without documented glaucomatous damage. Use it when the chart specifies ocular hypertension rather than glaucoma.
Clinical signs
Findings typically include increased eye pressure on examination, often with a normal optic nerve and visual field. Clinical features vary; refer to documentation.
When to use this code
Use H40.051 when the provider documents ocular hypertension affecting only the right eye. It may also apply when elevated pressure is noted during follow-up and glaucoma is not diagnosed. If the record is unclear, check documentation.
Do not use for
Do not use this code for glaucoma, suspected glaucoma, or ocular hypertension in the left eye or both eyes. Do not assign it when the record only says increased eye pressure without laterality.
Coding tip
Always confirm laterality in the ophthalmology note before assigning H40.051.
