ICD-10 Code H01.119 – Allergic dermatitis of unspecified eye, unspecified eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H01.119 – Allergic dermatitis of unspecified eye, unspecified eyelid
What it is
This code identifies an allergic dermatitis affecting the eye area or eyelid, but the record does not specify which eye or eyelid. Use it when documentation confirms an allergic skin reaction around the eye without greater laterality detail.
Clinical signs
Typical findings include itching, redness, swelling, and irritated skin of the eyelid or periocular area. Clinical features vary; refer to documentation for the exact site and whether the reaction is allergic in origin.
When to use this code
Use H01.119 when the provider documents allergic dermatitis of an unspecified eye or unspecified eyelid and does not identify right or left. It also fits when the note describes periocular allergic dermatitis but laterality is not recorded. Check documentation if the chart mentions infection, conjunctivitis, or another distinct eye disorder.
Do not use for
Do not use this code for dermatitis with a documented right or left side, because a more specific code may apply. Do not assign it for nonallergic eyelid inflammation or eye conditions that are better described elsewhere.
Coding tip
If the note omits laterality, capture the unspecified code exactly as documented and query only when the record supports a more specific eye or eyelid site.
