ICD-10 Code D69.3 – Immune thrombocytopenic purpura (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D69.3 – Immune thrombocytopenic purpura
What it is
D69.3 identifies immune thrombocytopenic purpura, an immune-mediated disorder causing low platelet counts. It is used when the thrombocytopenia is due to immune destruction rather than another known cause.
Clinical signs
Typical findings include easy bruising, petechiae, mucosal bleeding, or other bleeding symptoms with isolated thrombocytopenia. Clinical features vary; refer to documentation.
When to use this code
Use D69.3 when the provider documents immune thrombocytopenic purpura, idiopathic thrombocytopenic purpura, or ITP. Apply it when the record supports an immune cause of thrombocytopenia and no other specific etiology is documented.
Do not use for
Do not use this code for thrombocytopenia from chemotherapy, infection, liver disease, or other documented secondary causes. Check documentation if the cause is unclear.
Coding tip
Confirm the provider’s stated cause of thrombocytopenia before assigning D69.3.
