ICD-10 Code H40.151 – Residual stage of open-angle glaucoma, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H40.151 – Residual stage of open-angle glaucoma, right eye
What it is
This code identifies residual-stage open-angle glaucoma in the right eye. It means the condition is chronic and has left lasting optic nerve or visual field damage, even if active progression is not documented.
Clinical signs
Typical findings include glaucomatous optic nerve changes, such as cupping, and corresponding visual field loss. Clinical features vary; refer to documentation.
When to use this code
Use H40.151 when the provider documents residual stage open-angle glaucoma specifically in the right eye. Apply it when the record supports a chronic post-damage state rather than an acute or unspecified glaucoma stage.
If laterality is documented and the right eye is affected, this code is the appropriate choice. Check documentation when the stage is unclear or when both eyes are involved.
Do not use for
Do not use this code for glaucoma that is acute, unspecified, or documented in another stage. Do not assign it when the right eye is not specified or when documentation only states glaucoma without residual-stage detail.
Coding tip
Verify both laterality and stage in the ophthalmology note before coding H40.151.
