ICD-10 Code D82.0 – Wiskott-Aldrich Syndrome (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D82.0 – Wiskott-Aldrich syndrome
What it is
D82.0 identifies Wiskott-Aldrich syndrome, an inherited immune disorder that affects how the body fights infection and maintains normal blood cell function. It is a rare primary immunodeficiency.
Clinical signs
Typical findings include recurrent infections, eczema, and thrombocytopenia with small platelets. Clinical features vary; refer to documentation.
When to use this code
Use D82.0 when the provider documents Wiskott-Aldrich syndrome by name or clearly confirms the diagnosis. It also fits records describing the syndrome’s classic immune deficiency pattern with eczema and low platelets. If the note only suggests a possible inherited immunodeficiency, check documentation before coding.
Do not use for
Do not use this code for isolated eczema, thrombocytopenia, or recurrent infections without a documented Wiskott-Aldrich diagnosis. Check documentation if the condition is being evaluated rather than confirmed.
Coding tip
Code D82.0 only when the chart supports the specific syndrome, not a nonspecific immunodeficiency.
