ICD-10 Code H40.41 – Glaucoma secondary to eye inflammation, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H40.41 – Glaucoma secondary to eye inflammation, right eye
What it is
This code identifies glaucoma in the right eye that develops because of ocular inflammation. Use it when the record shows the glaucoma is secondary to an inflammatory eye disorder, not primary glaucoma.
Clinical signs
Typical findings include elevated intraocular pressure, optic nerve damage, and visual field loss in the affected eye. Clinical features vary; refer to documentation for the inflammatory cause and laterality.
When to use this code
Use H40.41 when the provider documents glaucoma due to eye inflammation in the right eye. It is appropriate when the note links the glaucoma to uveitis, iritis, or another inflammatory condition. Check documentation if the cause or eye laterality is unclear.
Do not use for
Do not use this code for primary glaucoma or for inflammation without documented glaucoma. If the record does not specify the right eye, or if the condition is unspecified, check documentation.
Coding tip
Confirm both the secondary cause and right-eye laterality before assigning H40.41.
