2025 ICD-10-CM code L30.1

Dyshidrosis, also known as pompholyx, is a recurrent skin condition characterized by small, itchy blisters on the hands and sometimes feet.

Accurate diagnosis and coding of dyshidrosis requires careful differentiation from other vesicular dermatoses. If associated with a specific irritant or allergen, additional coding for contact dermatitis might be necessary.

Medical necessity for treatment of dyshidrosis is established based on the significant impact of the condition on the patient's quality of life due to pruritus and disruption of daily activities.Treatment aims to alleviate symptoms and improve patient well-being.

Diagnosis and management of dyshidrosis, including assessment of associated conditions, and selection of appropriate treatment strategies (topical corticosteroids, emollients, antihistamines).

IMPORTANT May be associated with or related to other conditions such as atopic dermatitis (L20), contact dermatitis (L23-L25).Differentiation is crucial for accurate coding.

In simple words: Dyshidrosis, or pompholyx, causes itchy, small blisters mainly on the hands and sometimes the feet.It comes and goes and the cause isn't fully understood. Treatment aims to relieve itching and the blisters.

Dyshidrosis (pompholyx) is a recurrent vesicular eruption primarily affecting the hands, often the sides of the digits, and occasionally the feet.The etiology remains unclear; a direct link to sweating has not been established.Lesions are intensely pruritic.Associated conditions may include atopic dermatitis, contact irritants/allergens, dermatophyte/bacterial infections, hyperhidrosis, heat exposure, high dietary nickel/cobalt intake, and emotional stress.Treatment focuses on symptomatic relief and vesiculation control.

Example 1: A 35-year-old female presents with intensely itchy, small blisters on the sides of her fingers. The blisters have been recurring for several months, and she reports no known allergies or other relevant medical history. Diagnosis: L30.1 Dyshidrosis., A 28-year-old male with a history of atopic dermatitis develops a new outbreak of small, fluid-filled blisters on his palms and soles.The patient also reports increased stress at work recently. Diagnosis: L30.1 Dyshidrosis., A 40-year-old female presents with chronic, recurring blisters on her hands, which are intensely itchy and interfere with her daily activities. She works as a hairdresser and has frequent contact with chemicals. The physician suspects a contact allergy in addition to dyshidrosis.Diagnosis: L30.1 Dyshidrosis with possible contributing contact allergy (additional coding may be required).

Detailed history including duration and location of lesions, presence of pruritus, associated conditions (atopic dermatitis, contact dermatitis), occupational exposures, relevant family history.Physical examination findings should be clearly documented, including description of lesions (size, distribution, morphology), presence of erythema, scaling, or secondary infection.Treatment plan and response to treatment should be recorded.

** Consider additional coding for associated conditions such as atopic dermatitis, contact dermatitis, or secondary infections if present.Documentation must be thorough to support the diagnosis and justify medical necessity.
