ICD-10 Code H40.149 – Capsular Glaucoma with Pseudoexfoliation of Lens, Unspecified Eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H40.149 – Capsular glaucoma with pseudoexfoliation of lens, unspecified eye
What it is
This code identifies glaucoma caused by pseudoexfoliation material on the lens capsule, but the affected eye is not specified. It is used when the record documents capsular glaucoma with pseudoexfoliation and laterality is missing or unclear.
Clinical signs
Findings may include elevated intraocular pressure, optic nerve damage, and visual field loss consistent with glaucoma. Clinical features vary; refer to documentation for the eye involved and any exam findings supporting pseudoexfoliation.
When to use this code
Use H40.149 when the provider documents capsular glaucoma with pseudoexfoliation of the lens and does not identify right, left, or bilateral eye. It also fits when the note confirms pseudoexfoliation glaucoma but laterality is unavailable. Check documentation before coding a more specific option.
Do not use for
Do not use this code for pseudoexfoliation without glaucoma, or for other open-angle glaucoma types. Do not assign it when the chart clearly states the right, left, or bilateral eye and a more specific code is available.
Coding tip
If laterality is missing, query the provider when possible; otherwise, code the unspecified eye only as documented.
