ICD-10 Code H40.131 – Pigmentary glaucoma, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H40.131 – Pigmentary glaucoma, right eye
What it is
H40.131 identifies pigmentary glaucoma affecting the right eye. It is a form of glaucoma associated with pigment dispersion that can damage the optic nerve and reduce vision.
Clinical signs
Typical findings include pigment in the anterior chamber, elevated intraocular pressure, and glaucomatous optic nerve changes. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents pigmentary glaucoma in the right eye. It applies when the diagnosis is confirmed, suspected as the documented working diagnosis, or listed as an active condition in the record. If laterality is not specified, check documentation before coding.
Do not use for
Do not use it for pigment dispersion syndrome without glaucoma, or for glaucoma in the left eye or both eyes. Check documentation if the record only mentions ocular hypertension or a different glaucoma type.
Coding tip
Verify laterality carefully, because H40.131 is specific to the right eye and should match the provider’s documented diagnosis.
