ICD-10 Code I82.441 – Acute embolism and thrombosis of right tibial vein (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.441 – Acute embolism and thrombosis of right tibial vein
What it is
I82.441 identifies an acute blood clot or embolus in the right tibial vein, a deep vein in the lower leg. Use it when documentation specifies the right side and the condition is acute.
Clinical signs
Typical findings include unilateral leg pain, swelling, warmth, tenderness, or calf discomfort. Diagnosis is usually supported by imaging or clear provider documentation of acute deep vein thrombosis.
When to use this code
Use this code when the record states acute embolism or thrombosis involving the right tibial vein, including a confirmed deep vein thrombosis in that vessel. It also fits situations where the provider documents an acute clot in the right lower-leg deep venous system and identifies the tibial vein specifically.
Do not use for
Do not use it for chronic, old, or history-only thrombosis, or when the clot is in a different vein. Check documentation if the laterality, acuity, or exact vein is unclear.
Coding tip
Always verify both acuity and right-sided tibial vein involvement before assigning I82.441.
