Thrombocytopenia, commonly referred to as low platelet count, is a medical condition characterized by a decrease in the number of platelets (thrombocytes) in the blood. Platelets play a crucial role in blood clotting and wound healing, making their adequate levels vital for maintaining hemostasis. When platelet levels drop below normal, it can lead to increased bleeding risk, bruising, and in severe cases, life-threatening hemorrhages. Accurate documentation and coding of this condition are essential for proper diagnosis, treatment, billing, and statistical analysis. In the healthcare industry, the International Classification of Diseases, Tenth Revision (ICD-10) provides standardized codes for various medical conditions, including thrombocytopenia.
In this comprehensive guide, we will explore low plts ICD 10, covering causes, symptoms, diagnosis, treatment options, and how to accurately code this condition using ICD-10. Whether you're a healthcare provider, coder, or patient seeking understanding, this article aims to shed light on the critical aspects of low platelet counts and their documentation.

Understanding Thrombocytopenia (Low Platelet Count)
What Is Thrombocytopenia?
Thrombocytopenia refers to a condition where the blood has fewer than 150,000 platelets per microliter. Normal platelet counts typically range from 150,000 to 450,000 per microliter of blood. When levels fall below this range, patients may experience symptoms such as easy bruising, petechiae (small red or purple spots on the skin), bleeding gums, or prolonged bleeding from cuts.
Causes of Low Platelet Count
Thrombocytopenia can result from various underlying conditions, including:
- Bone marrow disorders (e.g., leukemia, myelodysplastic syndromes)
- Autoimmune diseases (e.g., immune thrombocytopenic purpura - ITP)
- Infections (e.g., HIV, hepatitis C, dengue fever)
- Medications (e.g., heparin, chemotherapy drugs)
- Alcohol abuse
- Pregnancy
- Splenomegaly (enlarged spleen)
- Viral infections
Symptoms and Signs
While some individuals with low platelet counts may be asymptomatic, others may experience:
- Petechiae or purpura
- Easy bruising
- Prolonged bleeding from minor cuts
- Bleeding from gums or nose
- Blood in urine or stool
- Heavy menstrual periods

Diagnosis and Evaluation of Low Platelet Counts
Laboratory Tests
The primary diagnostic tool for thrombocytopenia is a complete blood count (CBC), which provides the platelet count and other blood cell levels. Additional tests may include:
- Peripheral blood smear
- Bone marrow biopsy
- Tests for underlying infections or autoimmune markers
- Serological tests for viral infections
Differential Diagnosis
Distinguishing between causes involves evaluating clinical history, laboratory results, and sometimes bone marrow examination. Important considerations include:
- Is the low platelet count due to decreased production or increased destruction?
- Are there other blood abnormalities?
- Is an autoimmune process involved?

Treatment Options for Low Platelet Count
General Management Strategies
Treatment depends on the severity of thrombocytopenia and its underlying cause. Common approaches include:
- Monitoring mild cases without active treatment
- Discontinuing causative medications
- Treating underlying infections or autoimmune conditions
- Platelet transfusions in severe cases
- Medications to stimulate platelet production
- Splenectomy in chronic cases
Medications Used
Some common medications include:
- Immunoglobulins (IVIG)
- Thrombopoietin receptor agonists (e.g., eltrombopag, romiplostim)
- Corticosteroids
When to Seek Emergency Care
Emergency intervention is necessary if the patient experiences:
- Severe bleeding
- Signs of internal hemorrhage
- Uncontrolled bleeding from gums, nose, or wounds

ICD-10 Coding for Low Platelet Count
Understanding the ICD-10 System
ICD-10 codes are alphanumeric codes used internationally to classify diseases and health conditions. Accurate coding ensures proper documentation, reimbursement, and statistical tracking.
Primary ICD-10 Codes for Thrombocytopenia
The main ICD-10 codes related to low platelet counts include:
- D69.3: Idiopathic thrombocytopenic purpura (ITP)
- D69.4: Other primary thrombocytopenia
- D69.59: Secondary thrombocytopenia, other specified
- D69.59: Other specified secondary thrombocytopenia
- D69.6: Thrombocytopenia, unspecified
When to Use Specific Codes
- Use D69.3 for cases diagnosed as ITP, an autoimmune form of thrombocytopenia.
- Use D69.4 when the cause is other primary thrombocytopenia not specified as ITP.
- Use D69.59 if the thrombocytopenia is secondary to other conditions, such as infections or medications.
- Use D69.6 if the cause remains unspecified after evaluation.
Coding for Underlying Causes
In many cases, it’s essential to code both the thrombocytopenia and its underlying condition. For example:
- Suppose a patient has thrombocytopenia due to leukemia:
- Code for leukemia (e.g., C92.0)
- Code for thrombocytopenia (e.g., D69.6)
- For thrombocytopenia caused by medication:
- Code for the adverse effect of the drug (e.g., T45.1X5A for adverse effect of heparin)
- Code for thrombocytopenia (e.g., D69.6)
Additional Codes and Considerations
Always review the latest ICD-10 guidelines, as updates may influence code selection. Also, document the severity, cause, and any complications related to thrombocytopenia for precise coding.

Importance of Accurate Coding and Documentation
Proper coding of low plts (thrombocytopenia) ensures:
- Accurate clinical records
- Appropriate billing and reimbursement
- Reliable data for epidemiological studies
- Better patient care through comprehensive documentation
Healthcare providers and coders should stay updated with ICD-10 coding guidelines and ensure detailed clinical documentation to support the chosen codes.

Summary
Understanding low plts ICD 10 coding involves knowing the various causes of thrombocytopenia, recognizing its symptoms, and applying the correct ICD-10 codes based on the underlying etiology. Accurate documentation not only facilitates effective treatment but also ensures proper reimbursement and data analysis. Whether dealing with primary immune thrombocytopenia (ITP), secondary causes like infections or medications, or unspecified thrombocytopenia, healthcare providers must be precise in their coding practices to reflect the patient’s condition accurately.
By mastering ICD-10 coding for low platelets, clinicians and medical coders can improve healthcare delivery, support research, and enhance patient outcomes. Staying informed about updates and guidelines is essential for maintaining coding accuracy and delivering high-quality care.
