Code Description

ICD-10 O22.32 is a billable code used to indicate a diagnosis of deep phlebothrombosis in pregnancy, second trimester.

Key Diagnostic Point:

Deep phlebothrombosis (DVT) in pregnancy is a serious condition characterized by the formation of a blood clot in a deep vein, typically in the legs. During the second trimester, physiological changes such as increased blood volume, hormonal fluctuations, and venous stasis contribute to the risk of thromboembolic events. Pregnant women are particularly susceptible due to the compression of pelvic veins by the enlarging uterus, which can impede venous return and lead to clot formation. Symptoms may include unilateral leg swelling, pain, tenderness, and discoloration. Diagnosis is often confirmed through imaging studies such as Doppler ultrasound. Management typically involves anticoagulation therapy to prevent clot extension and reduce the risk of pulmonary embolism, which is a life-threatening complication. Close monitoring and follow-up are essential to ensure maternal and fetal safety throughout the treatment process.

Audit Risk Factors

  • Inadequate documentation of symptoms and clinical findings.
  • Failure to document the rationale for anticoagulation therapy.
  • Misclassification of DVT severity or type.
  • Lack of follow-up documentation post-treatment.

Documentation Requirements

Detailed documentation of symptoms, diagnostic imaging results, and treatment plans is essential for accurate coding.

Common Clinical Scenarios

A pregnant patient presents with unilateral leg swelling and pain; Doppler ultrasound confirms DVT.

Billing Considerations

Consideration of the patient's obstetric history and any previous thromboembolic events is crucial for accurate coding.

Documentation Requirements

Comprehensive documentation of maternal and fetal health, including any high-risk factors for thrombosis.

Common Clinical Scenarios

Management of a pregnant patient with a history of DVT requiring anticoagulation therapy.

Billing Considerations

Close monitoring of both maternal and fetal well-being during anticoagulation therapy is necessary.
