2025 ICD-10-CM code I82.4Z9
(Active) Effective Date: N/A Diseases of the circulatory system - Diseases of veins, lymphatic vessels and lymph nodes, not elsewhere classified 9 Feed
Acute embolism and thrombosis of unspecified deep veins of unspecified distal lower extremity.
Medical necessity must be established through documentation demonstrating the presence of a DVT and the need for treatment. This could include clinical findings and imaging results.
Diagnosis and management of this condition falls under the purview of vascular specialists, internists, hospitalists, or other healthcare professionals depending on the specific clinical scenario and setting.
In simple words: This code represents a blood clot in the deep veins of the lower leg, below the knee, but the exact location is not specified.
Acute embolism and thrombosis of unspecified deep veins of unspecified distal lower extremity. This includes acute embolism and thrombosis of deep vein of calf NOS, and acute embolism and thrombosis of deep vein of lower leg NOS.
Example 1: A patient presents with pain, swelling, and redness in the lower leg. After examination and ultrasound imaging, the physician diagnoses an acute deep vein thrombosis (DVT) in the distal lower extremity, without specifying the exact vein affected. I82.4Z9 is used for coding., A patient with a history of varicose veins experiences sudden onset of pain and swelling in the calf. Imaging reveals a blood clot in the deep veins of the distal lower leg. As the specific vein isn't identified, I82.4Z9 is used., Post-surgery, a patient experiences tenderness and edema in the lower leg. A Doppler ultrasound confirms the presence of a DVT, but does not pinpoint the specific vein involved. The diagnosis is coded as I82.4Z9.
Documentation should include signs and symptoms, location of the DVT, results of diagnostic tests like ultrasound, and any associated conditions or risk factors.
