ICD-10 Code I82.461 – Acute embolism and thrombosis of right calf muscular vein (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.461 – Acute embolism and thrombosis of right calf muscular vein
What it is
This code identifies an acute blood clot or embolus in a muscular vein of the right calf. Use it when documentation specifies the right calf muscular vein and an acute venous thrombosis or embolism.
Clinical signs
Typical findings include localized calf pain, swelling, tenderness, and possible warmth or redness. Clinical features vary; refer to documentation and imaging or provider assessment when recorded.
When to use this code
Use I82.461 when the provider documents acute thrombosis or embolism in a right calf muscular vein, such as the soleal or gastrocnemius veins. It is appropriate for confirmed or clearly diagnosed acute venous clotting in that location. Check documentation if laterality or acuity is unclear.
Do not use for
Do not use this code for chronic, unspecified, or left-sided calf vein thrombosis. Do not assign it when the clot is in a different venous segment or when documentation only says “DVT” without the required specificity.
Coding tip
Verify both acuity and right-sided calf muscular vein location before coding, because missing laterality or vein detail can change the code.
