ICD-10 Code H10.213 – Acute toxic conjunctivitis, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H10.213 – Acute toxic conjunctivitis, bilateral
What it is
This code identifies an acute inflammation of both conjunctivae caused by a toxic or irritant exposure. Use it when documentation clearly states bilateral toxic conjunctivitis.
Clinical signs
Typical findings include red, irritated eyes with tearing, burning, or discomfort after exposure to an irritant. Clinical features vary; refer to documentation.
When to use this code
Use H10.213 when the record documents acute toxic conjunctivitis affecting both eyes, such as after chemical, environmental, or other irritant exposure. Code it only when the provider identifies the condition as toxic and bilateral. Check documentation if laterality or cause is unclear.
Do not use for
Do not use this code for allergic conjunctivitis, infectious conjunctivitis, or nonspecific eye irritation without a toxic cause. Do not assume bilateral disease unless both eyes are documented.
Coding tip
Verify both the toxic cause and bilateral laterality in the note before assigning H10.213.
