Acute embolism and thrombosis of unspecified tibial vein

This code signifies a sudden blockage of blood flow within an unspecified tibial vein due to an embolus (a traveling clot) or a thrombus (a stationary clot). This acute event can lead to pain, swelling, and potential complications if not addressed.

Use this code when documentation clearly indicates an acute embolism or thrombosis affecting a tibial vein, but the specific tibial vein (e.g., anterior, posterior, peroneal) is not specified. Supporting documentation would include imaging reports (e.g., ultrasound, venography) confirming the presence of a clot in an unspecified tibial vein, along with clinical notes describing an acute onset of symptoms.

• Ensure the documentation specifies "acute" to differentiate from chronic conditions.
• Avoid using this code if the specific tibial vein is identified; instead, use the more specific code (e.g., I82.441 for anterior tibial vein).
• Always review imaging reports and physician notes for laterality (left, right, bilateral) and specificity of the affected vessel.
