AHA Coding Clinic® for ICD-10-CM and ICD-10-PCS - 2019 Quarter 4; New/Revised ICD-10-CM Codes
Deep Vein Thrombosis
New codes have been created to identify acute and chronic venous embolism and thrombosis of deep vessels of the distal lower extremities, such as the peroneal vein and calf muscular vein. Deep vein thrombosis (DVT), also referred to as venous thromboembolism, is a blood clot in a major vein, generally occurring in the legs or pelvis. Calf vein thrombosis refers to any clot affecting the deep veins of the calf, also known as the distal portion of the lower extremity, without extending into the popliteal vein. The calf veins include three paired veins (posterior tibial, peroneal, and anterior tibial)...

Article Overview
This article covers updates to ICD-10-CM coding for deep vein thrombosis affecting distal lower-extremity veins, including how the new code groupings separate acute and chronic conditions and distinguish specific vein locations. It is relevant to coding professionals, auditors, and clinical documentation teams who need to understand the scope of the new DVT categories and the broader clinical context behind them.
Why This Topic Matters
Changes in DVT coding affect documentation specificity, code selection, and tracking of venous thromboembolic disease by vessel location and condition timing. The article helps readers recognize the categories addressed by the new ICD-10-CM structure and why distal-vein thrombosis is being coded more specifically.
