ICD-10 Code I82.562 – Chronic embolism and thrombosis of left calf muscular vein (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.562 – Chronic embolism and thrombosis of left calf muscular vein
What it is
I82.562 identifies a chronic clot or embolic blockage in a left calf muscular vein, such as the soleal or gastrocnemius veins. Use it when the record clearly states the condition is chronic and limited to the left calf muscular vein.
Clinical signs
Clinical features vary; refer to documentation. Commonly documented findings include persistent calf pain, swelling, tenderness, or a history of prior venous thrombosis with imaging or provider confirmation of chronic clot.
When to use this code
Use this code when the provider documents chronic embolism or thrombosis in a left calf muscular vein and the location is specified. It is appropriate for follow-up encounters, residual clot, or chronic venous obstruction when the left calf muscular vein is named.
Do not use for
Do not use it for acute DVT, superficial thrombophlebitis, or thrombosis in a different vein location. Check documentation if the site is only described as lower extremity or if chronicity is not stated.
Coding tip
Code only when both chronicity and the left calf muscular vein are documented; otherwise, query or check documentation.
