ICD-10 Code H10.11 – Acute atopic conjunctivitis, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H10.11 – Acute atopic conjunctivitis, right eye
What it is
H10.11 identifies acute atopic conjunctivitis affecting the right eye. Use it when documentation states an atopic, allergic-type conjunctival inflammation limited to the right eye.
Clinical signs
Typical findings include red, itchy, and watery conjunctiva, often with eyelid irritation or swelling. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents acute atopic conjunctivitis in the right eye, or clearly records atopic conjunctivitis with right-eye laterality. It is appropriate for initial or active encounters tied to that diagnosis. If the record does not specify laterality, check documentation.
Do not use for
Do not use H10.11 for unspecified conjunctivitis, non-atopic allergic conjunctivitis, or left-eye or bilateral disease. Check documentation if the cause or eye laterality is unclear.
Coding tip
Always verify both the atopic diagnosis and right-eye laterality before assigning H10.11.
