ICD-10 Code H35.381 – Toxic maculopathy, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.381 – Toxic maculopathy, right eye
What it is
This code identifies toxic damage to the macula in the right eye. The macula is the central retinal area needed for sharp, detailed vision.
Clinical signs
Patients may report blurred central vision, reduced reading ability, or metamorphopsia. Clinical features vary; refer to documentation, and confirm the right eye is affected.
When to use this code
Use H35.381 when the record documents toxic maculopathy limited to the right eye. Apply it for medication- or toxin-related macular injury when the provider specifies the eye involved.
If the note describes bilateral disease, another laterality code is needed. Check documentation when the cause is unclear or when macular changes are not explicitly linked to toxicity.
Do not use for
Do not use this code for nonspecific macular degeneration, retinal toxicity without macular involvement, or unspecified eye laterality. Check documentation.
Coding tip
Always verify laterality and the toxic cause in the provider note before assigning H35.381.
