ICD-10 Code H01.111 – Allergic dermatitis of right upper eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H01.111 – Allergic dermatitis of right upper eyelid
What it is
H01.111 identifies allergic dermatitis affecting the right upper eyelid. Use it when the reaction is limited to that eyelid and documented as allergic or contact dermatitis.
Clinical signs
Typical findings include eyelid redness, itching, swelling, scaling, or irritation. Clinical features vary; refer to documentation for the exact side and whether the process is allergic.
When to use this code
Use this code when the provider documents allergic dermatitis on the right upper eyelid only. It also fits cases described as contact dermatitis of that eyelid if the record supports an allergic cause. Confirm laterality before assigning the code.
Do not use for
Do not use it for dermatitis of the left eyelid, both eyelids, or an unspecified eyelid. Check documentation if the note describes blepharitis, infection, or another nonallergic eyelid disorder.
Coding tip
Verify both laterality and the allergic nature of the dermatitis before coding H01.111.
