ICD-10 Code H40.152 – Residual stage of open-angle glaucoma, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H40.152 – Residual stage of open-angle glaucoma, left eye
What it is
This code identifies residual-stage open-angle glaucoma in the left eye. Use it when the chart documents glaucoma damage that remains after treatment or progression has stabilized.
Clinical signs
Findings may include optic nerve cupping, visual field loss, and a history of open-angle glaucoma in the left eye. Clinical features vary; refer to documentation.
When to use this code
Use H40.152 when the provider specifically documents residual stage and laterality as the left eye. It fits follow-up visits for established glaucoma with persistent structural or functional damage. If the record only says open-angle glaucoma without stage, check documentation.
Do not use for
Do not use this code for glaucoma in the right eye or both eyes, or for unspecified laterality. Avoid it when the stage is not documented or when the diagnosis is a different glaucoma type.
Coding tip
Confirm both the stage and the eye in the provider note before assigning H40.152.
