ICD-10 Code H01.112 – Allergic dermatitis of right lower eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H01.112 – Allergic dermatitis of right lower eyelid
What it is
This code identifies an allergic inflammation of the skin on the right lower eyelid. Use it when documentation specifies the right lower eyelid and an allergic cause.
Clinical signs
Typical findings include eyelid redness, itching, swelling, and irritation. Clinical features vary; refer to documentation, especially if the record distinguishes dermatitis from infection or other eyelid disorders.
When to use this code
Use H01.112 when the provider documents allergic dermatitis limited to the right lower eyelid. It may also apply when the note clearly states allergic eyelid dermatitis with laterality and location. Check documentation if the cause, side, or eyelid segment is unclear.
Do not use for
Do not use this code for nonspecific eyelid rash without allergic etiology or laterality. Do not assign it when the condition involves another eyelid, both eyelids, or a different diagnosis such as infection.
Coding tip
Confirm both the allergic nature and the exact right lower eyelid location before coding.
