2025 ICD-10-CM code O22.3
(Active) Effective Date: N/A Pregnancy, childbirth and the puerperium - Venous complications and haemorrhoids in pregnancy 15 Feed
Deep vein thrombosis in pregnancy.
Deep vein thrombosis in pregnancy is a serious condition that requires prompt diagnosis and treatment to prevent potentially life-threatening complications like pulmonary embolism. Medical necessity for treatment is established by the diagnosis of DVT confirmed by appropriate diagnostic testing.
Diagnosis and management of deep vein thrombosis during pregnancy falls under the purview of obstetricians, maternal-fetal medicine specialists, and potentially vascular specialists or hematologists depending on the complexity of the case.
In simple words: This code indicates a blood clot in a deep vein during pregnancy.
Deep vein thrombosis, antepartum. Use additional code to identify the deep vein thrombosis (I82.4-, I82.5-, I82.62-, I82.72-). Use additional code, if applicable, for associated long-term (current) use of anticoagulants (Z79.01).
Example 1: A 30-year-old woman in her second trimester presents with swelling and pain in her left leg. After diagnostic testing, she is diagnosed with a deep vein thrombosis and started on anticoagulant therapy., A pregnant woman with a history of deep vein thrombosis develops recurrent DVT in her third trimester. She is managed with anticoagulation throughout the remainder of her pregnancy and postpartum period., A woman in the early postpartum period experiences sudden shortness of breath and chest pain. Imaging reveals a pulmonary embolism, and subsequent investigation reveals a deep vein thrombosis as the source. This postpartum DVT is coded as O87.2, and the associated pulmonary embolism is coded separately.
Documentation should include details about the onset and location of symptoms, diagnostic testing results (e.g., ultrasound, D-dimer), treatment plan, and any associated complications. Specifying the trimester in which the DVT occurred is essential for accurate coding.
** It's important to distinguish between antepartum and postpartum deep vein thrombosis. While O22.3 is used for DVT during pregnancy, postpartum DVT is coded using O87.-.
