ICD-10 Code H40.43 – Glaucoma secondary to eye inflammation, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H40.43 – Glaucoma secondary to eye inflammation, bilateral
What it is
This code describes glaucoma caused by inflammation in both eyes. Use it when the record shows elevated intraocular pressure or optic nerve damage linked to an inflammatory eye condition.
Clinical signs
Clinical features vary; refer to documentation. Common findings include signs of uveitis or other ocular inflammation, increased intraocular pressure, and glaucomatous optic nerve changes.
When to use this code
Use this code when the provider documents bilateral glaucoma secondary to eye inflammation, such as uveitis-related glaucoma. It applies when both eyes are affected and the inflammatory cause is clearly stated. Check documentation if laterality or cause is unclear.
Do not use for
Do not use this code for primary glaucoma, unilateral disease, or glaucoma from another cause. If the chart does not clearly link the glaucoma to inflammation, check documentation.
Coding tip
Assign the code only when the inflammatory etiology and bilateral involvement are documented together.
