ICD-10 Code I82.469 – Acute embolism and thrombosis of unspecified calf muscular vein (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.469 – Acute embolism and thrombosis of unspecified calf muscular vein
What it is
This code identifies an acute clot or embolus in a calf muscular vein when the exact vein is not specified. Use it for a newly diagnosed venous thrombosis in the muscular veins of the lower leg.
Clinical signs
Typical findings include unilateral calf pain, swelling, tenderness, or warmth. Clinical features vary; refer to documentation, and confirm that the provider documents an acute thrombotic or embolic event in an unspecified calf muscular vein.
When to use this code
Use this code when the record clearly states acute embolism or thrombosis involving a calf muscular vein, but does not name a more specific vein. It fits initial encounters and confirmed diagnoses documented as acute. If the note only says “DVT” without location, check documentation.
Do not use for
Do not use it for chronic, old, or history-only thrombosis. Do not assign it when the clot is in a different vein segment, such as the popliteal or femoral vein.
Coding tip
Match the code to the exact vein and acuity stated in the provider note; if either is unclear, check documentation before coding.
