ICD-10 Code H35.382 – Toxic maculopathy, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.382 – Toxic maculopathy, left eye
What it is
This code identifies toxic damage to the macula in the left eye. The macula is the central retina responsible for sharp, detailed vision.
Clinical signs
Patients may report blurred central vision, difficulty reading, or distorted straight lines. Clinical features vary; refer to documentation.
When to use this code
Use H35.382 when the record documents toxic maculopathy affecting only the left eye. This may follow exposure to a medication or other toxic agent, but the diagnosis must clearly name the left eye. If laterality is not stated, check documentation.
Do not use for
Do not use this code for unspecified maculopathy, bilateral disease, or retinal disorders without toxic cause. Check documentation if the chart does not confirm left-eye involvement.
Coding tip
Confirm both the toxic etiology and left-eye laterality in the provider note before assigning H35.382.
