ICD-10 Code H01.113 – Allergic dermatitis of right eye, unspecified eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H01.113 – Allergic dermatitis of right eye, unspecified eyelid
What it is
This code identifies allergic dermatitis affecting the right eye area, with the eyelid not further specified. It signals an inflammatory skin reaction around the eye caused by an allergic trigger.
Clinical signs
Typical findings include redness, itching, swelling, and irritation of the right eyelid or surrounding skin. Clinical features vary; refer to documentation.
When to use this code
Use H01.113 when the provider documents allergic dermatitis limited to the right eye region and does not specify the upper or lower eyelid. Apply it when the record clearly supports an allergic skin reaction rather than infection or another eyelid disorder.
Do not use for
Do not use this code if the documentation identifies a different eyelid, both eyes, or a nonallergic cause. Check documentation when the diagnosis is blepharitis, conjunctivitis, or an unspecified rash.
Coding tip
Confirm laterality and eyelid specificity in the note before assigning H01.113.
