Deep phlebothrombosis in pregnancy, third trimester
ICD-10 O22.33 is a billable code used to indicate a diagnosis of deep phlebothrombosis in pregnancy, third trimester.
Deep phlebothrombosis (DVT) in pregnancy, particularly during the third trimester, is a significant venous complication characterized by the formation of a thrombus in the deep veins, most commonly in the lower extremities. This condition poses serious risks to both the mother and fetus, including potential pulmonary embolism, which can be life-threatening. The physiological changes during pregnancy, such as increased blood volume, hormonal changes, and venous stasis due to the growing uterus, contribute to a heightened risk of thrombus formation. Symptoms may include unilateral leg swelling, pain, and tenderness, but some patients may be asymptomatic. Diagnosis typically involves imaging studies such as Doppler ultrasound. Management often includes anticoagulation therapy, which must be carefully monitored to balance the risks of thrombosis against potential bleeding complications. The third trimester is particularly critical as the risk of DVT increases, necessitating vigilant monitoring and appropriate intervention to ensure maternal and fetal safety.
Detailed documentation of patient history, physical examination findings, and treatment plans, including anticoagulation management.
Patients presenting with leg swelling and pain in the third trimester, requiring evaluation for DVT.
Consideration of the patient's obstetric history and any previous thrombotic events.
Comprehensive documentation of maternal and fetal assessments, including ultrasound findings and laboratory results.
Management of high-risk pregnancies with a history of thrombosis or other co-morbidities.
Coordination of care with hematology for anticoagulation management.
Used to confirm DVT diagnosis in pregnant patients.
Document the indication for the ultrasound and findings.
Ensure coordination with obstetric care for comprehensive management.
Signs of DVT may include swelling, pain, tenderness, and warmth in one leg. However, some patients may be asymptomatic, making awareness and screening essential.
