ICD-10 Code H35.383 – Toxic maculopathy, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.383 – Toxic maculopathy, bilateral
What it is
H35.383 identifies toxic damage to the macula in both eyes. The macula is the central retina responsible for sharp, detailed vision.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include reduced central vision, blurred vision, or color vision changes, with bilateral macular abnormalities on eye examination.
When to use this code
Use H35.383 when the record documents toxic maculopathy affecting both eyes. This may follow exposure to a medication or other toxic agent, but the cause should be stated or clearly linked in the chart.
Choose this code when the provider identifies bilateral macular toxicity rather than a nonspecific retinal disorder. If laterality is not documented, check the note before assigning a bilateral code.
Do not use for
Do not use this code for unilateral toxic maculopathy or for macular disease without toxic cause. Check documentation if the record only mentions retinal toxicity or medication exposure without macular involvement.
Coding tip
Confirm both laterality and toxic etiology in the provider note before coding H35.383.
