ICD-10 Code H40.069 – Primary angle closure without glaucoma damage, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H40.069 – Primary angle closure without glaucoma damage, unspecified eye
What it is
This code identifies primary angle closure in an unspecified eye when there is no documented glaucomatous optic nerve damage. It means the eye’s drainage angle is narrowed or blocked, but glaucoma damage has not been recorded.
Clinical signs
Findings may include a shallow anterior chamber, elevated or intermittently elevated intraocular pressure, and a closed or occludable angle on gonioscopy. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents primary angle closure and specifically states there is no glaucoma damage. It also fits cases where the affected eye is not identified in the record. If laterality is documented, choose the more specific code.
Do not use for
Do not use this code for angle-closure glaucoma with optic nerve damage or for secondary angle closure. Check documentation if the record describes acute glaucoma attack, chronic glaucoma, or an unspecified glaucoma diagnosis instead.
Coding tip
Confirm both laterality and the absence of glaucoma damage before assigning H40.069.
