Code Description

ICD-10 O22.52 is a billable code used to indicate a diagnosis of cerebral venous thrombosis in pregnancy, second trimester.

Key Diagnostic Point:

Cerebral venous thrombosis (CVT) is a rare but serious condition that can occur during pregnancy, particularly in the second trimester. It involves the formation of a thrombus (blood clot) in the cerebral veins, which can lead to increased intracranial pressure, hemorrhage, and neurological deficits. The risk factors for CVT in pregnancy include hypercoagulable states, dehydration, prolonged immobility, and certain medical conditions such as antiphospholipid syndrome. Symptoms may include headache, visual disturbances, seizures, and altered mental status. Diagnosis is typically confirmed through imaging studies such as MRI or CT scans. Management often involves anticoagulation therapy to prevent further clot formation and to mitigate the risk of complications. Close monitoring and multidisciplinary care are essential for optimal outcomes for both the mother and the fetus.

Code Complexity Analysis

Complexity Rating: High

High Complexity

Complexity Factors

  • Requires understanding of specific pregnancy-related complications.
  • Involves knowledge of anticoagulation management in pregnancy.
  • Differentiation from other thrombotic conditions.
  • Need for precise documentation of clinical symptoms and imaging results.

Audit Risk Factors

  • Inadequate documentation of clinical symptoms.
  • Failure to document imaging studies confirming diagnosis.
  • Incorrect coding of anticoagulation therapy.
  • Misclassification of the trimester of pregnancy.

Specialty Focus

Medical Specialties

Obstetrics and Gynecology

Documentation Requirements

Detailed documentation of symptoms, imaging results, and treatment plans is essential. Providers should document the patient's history, risk factors, and any anticoagulation therapy initiated.

Common Clinical Scenarios

A pregnant patient presents with severe headaches and visual disturbances, leading to imaging that reveals cerebral venous thrombosis.

Billing Considerations

Coders must ensure that all relevant clinical details are captured to support the diagnosis and treatment provided.

Maternal-Fetal Medicine

Documentation Requirements

High-risk pregnancy documentation must include comprehensive assessments of maternal and fetal health, including any complications arising from CVT.

Common Clinical Scenarios

A patient with a history of thrombophilia presents with neurological symptoms during the second trimester.

Billing Considerations

Special attention should be given to the management of anticoagulation therapy and its implications for both mother and fetus.

Coding Guidelines

Inclusion Criteria

Use O22.52 When
  • According to ICD
  • 10 coding guidelines, specific documentation of the condition, trimester, and any associated complications is required
  • Coders should ensure that the diagnosis is supported by clinical evidence and that all relevant details are captured
