2025 ICD-10-CM code I82.40
Acute embolism and thrombosis of unspecified deep veins of lower extremity.This encompasses both deep vein thrombosis (DVT) and venous thromboembolism (VTE) without specifying the location within the lower extremity (proximal or distal).
Medical necessity for treatment of DVT is established by the presence of objective findings, such as a positive ultrasound or venogram, along with clinical signs and symptoms. Treatment aims to prevent complications like pulmonary embolism.
Diagnosis and management of deep vein thrombosis (DVT) generally falls under the purview of vascular specialists, internal medicine physicians, hospitalists, or emergency medicine physicians, depending on the acuity and setting of the condition.Treatment typically involves anticoagulation therapy and supportive care.

- I82.4 - Acute embolism and thrombosis of deep veins of lower extremity
In simple words: A blood clot in a deep vein of the lower leg, without specifying the exact location.
Acute embolism and thrombosis of unspecified deep veins of lower extremity. Deep vein thrombosis NOS. DVT NOS. Excludes1: acute embolism and thrombosis of unspecified deep veins of distal lower extremity (I82.4Z-) and acute embolism and thrombosis of unspecified deep veins of proximal lower extremity (I82.4Y-). Excludes2: venous embolism and thrombosis (of): cerebral (I63.6, I67.6), coronary (I21-I25), intracranial and intraspinal, septic or NOS (G08), intracranial, nonpyogenic (I67.6), intraspinal, nonpyogenic (G95.1), mesenteric (K55.0-), portal (I81), pulmonary (I26.-). Code first venous embolism and thrombosis complicating: abortion, ectopic or molar pregnancy (O00-O07, O08.7), pregnancy, childbirth and the puerperium (O22.-, O87.-).
Example 1: A patient presents to the emergency room with pain, swelling, and redness in their calf. Ultrasound confirms a DVT in an unspecified deep vein of the lower leg., A patient post-surgery develops symptoms of DVT.Imaging confirms a clot in a deep vein of the lower extremity, but the documentation doesn't specify if it's in the proximal or distal veins. Therefore, I82.40 is used., A patient with a history of DVT experiences recurrent symptoms.Duplex ultrasound shows a new thrombus in a deep vein of the lower leg, without specifying the precise location within the lower extremity.
Documentation should include signs, symptoms, location of the DVT (if known), diagnostic methods used (e.g., ultrasound), and treatment plan.
** While I82.40 exists for unspecified location, always aim for the most specific code possible.If the documentation provides more detail about the location of the thrombus within the lower extremity (e.g., proximal vs. distal), use the corresponding more specific code.Refer to iFrameAI for the latest coding updates and guidelines.
