ICD-10 Code D69.0 – Allergic purpura (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D69.0 – Allergic purpura
What it is
D69.0 identifies allergic purpura, also called Henoch-Schönlein purpura or IgA vasculitis. It describes a small-vessel vasculitic disorder that commonly causes skin bleeding and inflammation.
Clinical signs
Typical findings include palpable purpura, often on the legs and buttocks, with possible joint pain, abdominal symptoms, or kidney involvement. Clinical features vary; refer to documentation.
When to use this code
Use D69.0 when the provider documents allergic purpura or IgA vasculitis as the diagnosis. It is appropriate when the record supports a vasculitic purpuric rash rather than a nonspecific bruise or bleeding disorder. Check documentation if the note only says purpura without a clear cause.
Do not use for
Do not use this code for thrombocytopenic purpura, coagulation defects, or simple ecchymosis. If the documentation points to another vasculitis or an unclear rash, code the documented condition instead.
Coding tip
Confirm the provider uses allergic purpura, Henoch-Schönlein purpura, or IgA vasculitis before assigning D69.0.
