Also known as
Reactive thrombocytosis
Elevated platelet count due to an underlying condition.
Other disorders of white blood cells
Includes various white blood cell abnormalities, sometimes associated with thrombocytosis.
Myeloproliferative neoplasms
Although distinct, these can present with thrombocytosis requiring differentiation.
Other abnormal findings of blood chemistry
May be used if other, more specific codes are not applicable.
Follow this step-by-step guide to choose the correct ICD-10 code.
Is thrombocytosis due to an underlying condition?
Yes
Is it due to infection?
No
Code D75.81 Other specified disorders involving white blood cells
When to use each related code
| Description |
|---|
| Reactive thrombocytosis |
| Essential thrombocythemia |
| Primary myelofibrosis |
Coding reactive thrombocytosis without documenting the underlying cause leads to unspecified codes and lost specificity.
Incorrectly using terms like essential thrombocythemia can lead to miscoding and inaccurate clinical documentation.
Overlooking reactive thrombocytosis post-operatively can impact quality metrics and reimbursement.
Q: What are the key differential diagnoses to consider when a patient presents with reactive thrombocytosis, and how can I distinguish between them?
A: Reactive thrombocytosis, characterized by elevated platelet counts, often necessitates a thorough differential diagnosis to pinpoint the underlying cause. Key differentials include iron deficiency anemia, infection (both acute and chronic), inflammatory conditions such as rheumatoid arthritis or inflammatory bowel disease, malignancy, splenectomy, and rebound thrombocytosis post-chemotherapy or major surgery. Distinguishing between these requires a multi-faceted approach. Start with a detailed patient history focusing on recent infections, surgeries, bleeding episodes, and family history of blood disorders. A comprehensive physical exam, including assessment for splenomegaly or lymphadenopathy, is essential. Laboratory investigations like a complete blood count (CBC) with peripheral smear review, iron studies, inflammatory markers (CRP, ESR), and coagulation studies can provide further clues. Consider bone marrow biopsy in select cases with persistent or unexplained thrombocytosis to evaluate for myeloproliferative neoplasms. Explore how integrating these clinical and laboratory findings can guide your differential diagnosis and management strategy for patients with reactive thrombocytosis. Learn more about advanced diagnostic techniques for myeloproliferative neoplasms to enhance your diagnostic accuracy.
Q: How should I manage a patient with asymptomatic reactive thrombocytosis secondary to iron deficiency anemia, and what are the potential complications if left untreated?
A: Management of asymptomatic reactive thrombocytosis secondary to iron deficiency anemia primarily focuses on treating the underlying iron deficiency. Oral iron supplementation is usually the first line of treatment. Monitor hemoglobin, hematocrit, and iron studies regularly to assess response. Resolution of the iron deficiency typically leads to normalization of platelet counts. While reactive thrombocytosis itself is often asymptomatic, the underlying iron deficiency anemia can lead to fatigue, weakness, shortness of breath, and pallor. If left untreated, iron deficiency can progress, leading to more severe anemia and potentially impacting cardiovascular function. Furthermore, persistent iron deficiency can affect cognitive function and immune response. Consider implementing a patient education plan emphasizing medication adherence and dietary modifications rich in iron to improve treatment outcomes. Explore how addressing the underlying iron deficiency can mitigate the associated risks and improve patient well-being.
Patient presents with reactive thrombocytosis, secondary thrombocytosis, elevated platelet count, thrombocythemia. The patient's platelet count is [insert value] x 10^9L, exceeding the upper limit of normal. Differential diagnosis includes primary thrombocytosis, essential thrombocythemia, and myeloproliferative neoplasms. However, based on the patient's clinical presentation, history, and absence of JAK2, CALR, or MPL mutations, a diagnosis of reactive thrombocytosis is favored. Underlying causes are being investigated and may include infection, inflammation, iron deficiency anemia, recent surgery, trauma, or malignancy. Current symptoms include [list symptoms, e.g., headache, dizziness, fatigue, or asymptomatic]. Physical examination findings are [document relevant findings]. Treatment plan focuses on addressing the underlying cause of the elevated platelet count. Monitoring of platelet levels will continue with repeat complete blood count (CBC) in [timeframe]. Patient education provided regarding signs and symptoms of thrombosis and bleeding, although the risk of thrombotic complications is generally low in reactive thrombocytosis compared to essential thrombocythemia. ICD-10 code D75.81, Other specified platelet disorders, is currently assigned. Further investigations will be pursued to elucidate the underlying etiology and guide management. Prognosis is generally favorable depending on the resolution of the underlying condition.
