ICD-10 Code H01.135 – Eczematous dermatitis of left lower eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H01.135 – Eczematous dermatitis of left lower eyelid
What it is
This code identifies eczematous dermatitis affecting the left lower eyelid. It means an inflammatory, eczema-type skin condition on that specific eyelid.
Clinical signs
Typical findings include redness, scaling, itching, and irritation of the left lower eyelid. Clinical features vary; refer to documentation if the laterality or exact eyelid location is unclear.
When to use this code
Use H01.135 when the record clearly documents eczematous dermatitis limited to the left lower eyelid. You should code this when the provider specifies the site and does not describe a different eyelid disorder or a more general dermatitis diagnosis.
Do not use for
Do not use this code for dermatitis of another eyelid, both eyelids, or an unspecified eyelid. Check documentation if the note describes infection, blepharitis, or a non-eczematous skin condition.
Coding tip
Confirm laterality and eyelid location in the assessment, not just the exam, before assigning H01.135.
