Also known as
Immune thrombocytopenic purpura
A condition causing low platelet count due to immune system dysfunction.
Other primary thrombocytopenias
Other conditions causing low platelet counts not classified elsewhere.
Secondary thrombocytopenia
Low platelet count caused by an underlying condition or medication.
Thrombocytopenia unspecified
A general term for low platelet count without specifying the cause.
Follow this step-by-step guide to choose the correct ICD-10 code.
Is the thrombocytopenia caused by immune mechanisms?
Yes
Is it chronic or acute ITP?
No
Do NOT code as ITP. Explore other causes of thrombocytopenia.

Coding requires specifying if ITP is primary (immune) or secondary (another cause). Miscoding impacts data accuracy and reimbursement.
Differentiating acute and chronic ITP is crucial for accurate coding and affects severity reflection for quality reporting and payment.
Insufficient documentation of bleeding episodes or platelet levels can lead to undercoding severity, impacting reimbursement and quality metrics.
Patient presents with signs and symptoms suggestive of Immune Thrombocytopenic Purpura (ITP). Chief complaints include easy bruising, petechiae, and mucosal bleeding such as epistaxis or gingival bleeding. The patient denies any recent infections, significant weight loss, or family history of bleeding disorders. Physical examination reveals scattered petechiae and ecchymoses but no lymphadenopathy or hepatosplenomegaly. Complete blood count (CBC) demonstrates isolated thrombocytopenia with a platelet count of [insert platelet count], while other cell lines are within normal limits. Peripheral blood smear confirms reduced platelets and absence of abnormal cells. The patient's presentation meets the diagnostic criteria for ITP, characterized by isolated thrombocytopenia in the absence of other identifiable causes. Differential diagnoses considered include drug-induced thrombocytopenia, thrombotic thrombocytopenic purpura (TTP), and other inherited bleeding disorders, but these were ruled out based on clinical presentation and laboratory findings. Initial management will focus on observation if the patient is asymptomatic or mildly symptomatic with a platelet count above [insert threshold platelet count]. For patients with severe thrombocytopenia (platelet count below [insert threshold platelet count]) or significant bleeding, treatment options including corticosteroids, intravenous immunoglobulin (IVIG), or anti-Rh(D) immunoglobulin will be considered. Patient education regarding bleeding precautions and avoidance of medications that can exacerbate thrombocytopenia, such as nonsteroidal anti-inflammatory drugs (NSAIDs), will be provided. Follow-up appointments are scheduled to monitor platelet counts and assess treatment response. ICD-10 code I49.5, Immune thrombocytopenic purpura, is assigned.
