ICD-10 Code H40.142 – Capsular glaucoma with pseudoexfoliation of lens, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H40.142 – Capsular glaucoma with pseudoexfoliation of lens, left eye
What it is
This code identifies glaucoma caused by pseudoexfoliation material on the lens capsule in the left eye. It reflects a secondary open-angle glaucoma process linked to pseudoexfoliative disease.
Clinical signs
Typical findings include pseudoexfoliative deposits on the lens or anterior segment and glaucomatous optic nerve damage. Intraocular pressure may be elevated, but clinical features vary; refer to documentation.
When to use this code
Use H40.142 when the record clearly states capsular glaucoma with pseudoexfoliation involving the left eye. Code it when the provider documents pseudoexfoliative glaucoma, pseudoexfoliation syndrome with glaucoma, or equivalent wording for the left eye. Check documentation if laterality or glaucoma type is unclear.
Do not use for
Do not use this code for pseudoexfoliation without glaucoma, or for glaucoma in another eye. If the note only says “glaucoma” or “ocular hypertension,” you need more specific documentation.
Coding tip
Confirm both the pseudoexfoliation-related glaucoma diagnosis and left-eye laterality before assigning H40.142.
