ICD-10 Code I82.462 – Acute embolism and thrombosis of left calf muscular vein (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.462 – Acute embolism and thrombosis of left calf muscular vein
What it is
I82.462 identifies an acute clot blocking a muscular vein in the left calf. Use it for a new venous thromboembolic event limited to that specific site.
Clinical signs
Typical findings include unilateral calf pain, swelling, tenderness, or warmth. Diagnosis is usually confirmed by imaging; clinical features vary, so refer to documentation.
When to use this code
Use this code when the provider documents an acute embolism or thrombosis in the left calf muscular vein, such as the soleal or gastrocnemius veins. It fits confirmed acute deep venous thrombosis at that location, not a vague leg clot. Check documentation if the record does not clearly specify laterality or vein type.
Do not use for
Do not use it for chronic, old, or unspecified lower-extremity thrombosis. It is also not the right code for superficial vein thrombosis or clots in other left leg veins.
Coding tip
Verify that the note states both acute status and left calf muscular vein involvement before assigning I82.462.
