ICD-10 Code H01.115 – Allergic dermatitis of left lower eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H01.115 – Allergic dermatitis of left lower eyelid
What it is
H01.115 identifies allergic dermatitis affecting the left lower eyelid. It means the eyelid skin is inflamed because of an allergic reaction, not an infection or injury.
Clinical signs
Typical findings include redness, itching, swelling, and irritation of the left lower eyelid. Clinical features vary; refer to documentation if the record does not clearly state an allergic cause.
When to use this code
Use this code when the provider documents allergic dermatitis limited to the left lower eyelid. It is appropriate when the note specifies the eyelid location and allergic etiology. If the documentation only says “eyelid dermatitis” or does not identify laterality, check documentation.
Do not use for
Do not use H01.115 for infectious eyelid conditions, contact dermatitis without allergic wording, or generalized facial eczema. If the record does not confirm the left lower eyelid, do not assume this code.
Coding tip
Verify both laterality and the allergic nature of the dermatitis before assigning H01.115.
