ICD-10 Code I82.492 – Acute embolism and thrombosis of other specified deep vein of left lower extremity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.492 – Acute embolism and thrombosis of other specified deep vein of left lower extremity
What it is
This code identifies an acute blood clot or embolus in a deep vein of the left lower extremity that is not one of the more specifically named veins. It indicates a recent deep vein thrombosis in the left leg.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include unilateral leg swelling, pain, tenderness, warmth, or redness, but diagnosis should be supported by imaging or provider assessment.
When to use this code
Use this code when the provider documents an acute thrombosis or embolism in an other specified deep vein of the left lower extremity. It is appropriate when the affected vein is deep, left-sided, and not captured by a more specific DVT code. Check documentation if the report only says “DVT” without vein detail.
Do not use for
Do not use it for superficial vein thrombosis, chronic or old DVT, or thrombosis in a different extremity. If the record does not confirm an acute process or left lower-extremity deep vein involvement, check documentation.
Coding tip
Confirm acuity, laterality, and the exact vein named in the chart before assigning I82.492.
