Code Description

ICD-10 H01.135 is a billable code used to indicate a diagnosis of eczematous dermatitis of left lower eyelid.

Key Diagnostic Point:

Eczematous dermatitis of the left lower eyelid is characterized by inflammation of the skin in the eyelid area, often presenting with symptoms such as redness, itching, and scaling. The eyelids are composed of delicate skin that is prone to irritants and allergens, making them susceptible to various dermatological conditions. Eczematous dermatitis can arise from contact with allergens, irritants, or as a result of atopic dermatitis. The condition may progress from acute to chronic stages, leading to lichenification and thickening of the skin if left untreated. Diagnosis typically involves a thorough clinical examination and may require patch testing to identify specific allergens. The lacrimal system, which includes the tear ducts, can also be affected indirectly due to inflammation and swelling, potentially leading to dry eye symptoms. Understanding the periocular anatomy is crucial, as the eyelids play a vital role in protecting the eye and maintaining ocular health. Effective management often includes topical corticosteroids, emollients, and avoidance of known triggers.
