2026 ICD-10-CM Diagnosis Code H40.241 – Residual stage of angle-closure glaucoma, right eye
What it is
This code identifies residual-stage angle-closure glaucoma affecting the right eye. It indicates ongoing glaucomatous damage after an angle-closure event, with the right eye specified.
Clinical signs
Clinical features may include optic nerve damage, visual field loss, and a history of angle closure. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly states residual stage angle-closure glaucoma in the right eye. It is appropriate after the acute or prior angle-closure episode has left persistent glaucomatous findings. You should confirm laterality and stage in the provider note.
Do not use for
Do not use it for suspect glaucoma, open-angle glaucoma, or unspecified glaucoma. If the chart does not identify residual stage or right-eye involvement, check documentation.
Coding tip
Verify both the stage and laterality before assigning H40.241.
