ICD-10 Code H01.116 – Allergic dermatitis of left eye, unspecified eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H01.116 – Allergic dermatitis of left eye, unspecified eyelid
What it is
This code identifies allergic inflammation of the skin around the left eye when the eyelid is not further specified. Use it for a localized allergic dermatitis affecting the periocular area on the left side.
Clinical signs
Typical findings include itching, redness, swelling, and irritated or scaly skin near the left eye. Clinical features vary; refer to documentation if the eyelid involvement or allergic cause is not clearly stated.
When to use this code
Use this code when the record documents allergic dermatitis involving the left eye region and does not specify the eyelid further. It also fits cases where the clinician notes allergic dermatitis of the left eyelid but provides no additional detail. Make sure the documentation supports laterality and allergic etiology.
Do not use for
Do not use this code for infectious conjunctivitis, contact dermatitis without an allergic basis, or dermatitis of the right eye. If the eyelid side or diagnosis is unclear, check documentation.
Coding tip
Verify both laterality and the allergic nature of the dermatitis before assigning H01.116.
