Allergic purpura
ICD-10 D69.0 is a billable code used to indicate a diagnosis of allergic purpura.
Allergic purpura, also known as hypersensitivity vasculitis, is a condition characterized by the presence of purpura, which are small, purple spots on the skin caused by bleeding underneath the skin. This condition is often associated with allergic reactions, particularly to medications, infections, or other allergens. The pathophysiology involves an immune-mediated response leading to inflammation of the small blood vessels, resulting in increased vascular permeability and subsequent bleeding. Patients may present with symptoms such as petechiae, ecchymosis, and sometimes systemic symptoms like arthralgia or abdominal pain. It is crucial to differentiate allergic purpura from other bleeding disorders, such as thrombocytopenia or hemophilia, as these conditions have different underlying mechanisms and treatment approaches. Diagnosis typically involves a thorough clinical history, physical examination, and may include laboratory tests to assess platelet counts and coagulation profiles. Management focuses on identifying and avoiding triggers, and in some cases, corticosteroids may be indicated to reduce inflammation.
Detailed patient history, including allergic reactions and family history of bleeding disorders.
Patients presenting with unexplained purpura, requiring differentiation from thrombocytopenia or hemophilia.
Ensure comprehensive lab results are documented to support the diagnosis and rule out other conditions.
Thorough documentation of potential allergens and patient reactions.
Patients with a history of allergic reactions presenting with skin manifestations.
Documenting the timeline of symptoms in relation to allergen exposure is crucial.
Used to assess platelet levels and rule out thrombocytopenia.
Document the reason for the CBC and any relevant symptoms.
Hematology specialists should ensure that all relevant lab results are included in the patient's record.
Common triggers include medications, infections, and certain foods. Identifying these triggers is crucial for management and prevention of recurrence.
