ICD-10 Code H01.114 – Allergic dermatitis of left upper eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H01.114 – Allergic dermatitis of left upper eyelid
What it is
H01.114 identifies allergic dermatitis affecting the left upper eyelid. Use it when documentation shows an allergic skin reaction limited to that eyelid.
Clinical signs
Typical findings include eyelid redness, itching, swelling, and irritation. Clinical features vary; refer to documentation for laterality and whether the upper eyelid is specifically involved.
When to use this code
Use this code when the provider documents allergic dermatitis on the left upper eyelid, including contact or allergic-type eyelid inflammation. It is appropriate when the record clearly supports the left upper eyelid as the site. Check documentation if the note only says eyelid dermatitis without laterality.
Do not use for
Do not use it for dermatitis of the right eyelid, both eyelids, or unspecified eyelid site. Do not use it when the documentation points to infection, trauma, or another nonallergic cause.
Coding tip
Verify both the allergic nature and the left upper eyelid location before assigning H01.114.
