Code Description

ICD-10 D69.59 is a billable code used to indicate a diagnosis of other secondary thrombocytopenia.

Key Diagnostic Point:

Other secondary thrombocytopenia refers to a reduction in platelet count that is not classified under primary thrombocytopenia or other specific conditions. This condition can arise from various underlying causes, including infections, autoimmune disorders, malignancies, and certain medications. In patients with secondary thrombocytopenia, the platelet count may drop due to increased destruction of platelets, impaired production in the bone marrow, or sequestration in the spleen. Common clinical manifestations include easy bruising, prolonged bleeding from cuts, and petechiae. The diagnosis often requires a thorough clinical evaluation, including a detailed patient history, physical examination, and laboratory tests to identify the underlying cause. Management of secondary thrombocytopenia focuses on treating the underlying condition and may involve the use of corticosteroids, immunoglobulins, or platelet transfusions in severe cases. Understanding the etiology is crucial for effective treatment and prevention of complications such as significant bleeding episodes.

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of underlying causes requiring differential diagnosis
  • Need for comprehensive patient history and lab results
  • Potential overlap with other hematological conditions
  • Variability in clinical presentation and severity

Audit Risk Factors

  • Inadequate documentation of underlying conditions
  • Failure to specify the cause of thrombocytopenia
  • Misclassification of primary vs. secondary thrombocytopenia
  • Lack of supporting lab results

Specialty Focus

Medical Specialties

Hematology

Documentation Requirements

Detailed lab results, patient history, and treatment plans must be documented.

Common Clinical Scenarios

Patients presenting with unexplained bruising or bleeding, requiring evaluation for thrombocytopenia.

Billing Considerations

Ensure that all potential causes of thrombocytopenia are explored and documented to support coding.

Internal Medicine

Documentation Requirements

Comprehensive patient history and physical examination findings are essential.

Common Clinical Scenarios

Patients with chronic illnesses presenting with low platelet counts.

Billing Considerations

Documentation should clearly outline the relationship between the underlying condition and thrombocytopenia.

Coding Guidelines

Inclusion Criteria

Use D69.59 When
  • According to ICD
  • 10 coding guidelines, D69
  • 59 should be used when thrombocytopenia is secondary to another condition that is not specified elsewhere
  • Coders must ensure that the underlying cause is documented and coded appropriately

Exclusion Criteria

Used to evaluate patients presenting with symptoms of thrombocytopenia.

Documentation Requirements

Document the reason for the CBC and any relevant clinical findings.

Specialty Considerations

Hematology specialists should ensure that all relevant lab results are included in the patient's record.

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of secondary thrombocytopenia, enabling better tracking of underlying causes and improved patient management. This specificity aids in research and epidemiological studies.

ICD-9 vs ICD-10
