ICD-10 Code H35.38 – Toxic Maculopathy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.38 – Toxic maculopathy
What it is
Toxic maculopathy is damage to the macula caused by exposure to a harmful drug or other toxic substance. It refers to retinal injury affecting central vision, not a specific medication name.
Clinical signs
Patients may have blurred central vision, reading difficulty, or color vision changes. Exam findings can include macular pigment changes or retinal abnormalities; clinical features vary, so refer to documentation.
When to use this code
Use this code when the record documents macular toxicity or toxic retinal injury involving the macula. It is appropriate when the provider links the condition to a medication, chemical, or other toxic exposure. Check documentation for the specific cause and laterality details if reported.
Do not use for
Do not use this code for nonspecific vision complaints without documented toxic macular injury. Also avoid it when the chart describes another retinal disorder or maculopathy with a different confirmed cause.
Coding tip
Code the toxic maculopathy only when the provider clearly documents the toxic cause and macular involvement.
