Acute embolism and thrombosis of tibial vein, bilateral

This code signifies the sudden blockage of both tibial veins by an embolus (traveling clot) or a thrombus (stationary clot). This condition leads to impaired blood flow in the lower legs, potentially causing pain, swelling, and other complications. It represents an acute vascular event affecting the deep veins of both lower extremities.

Apply this code when documentation explicitly states an acute embolism or thrombosis affecting the tibial veins in both legs. Supporting documentation should include imaging reports (e.g., ultrasound, venography) confirming the presence and location of the clot(s) and a physician's diagnosis of acute onset.

• Ensure documentation specifies "acute" and "bilateral" involvement of the tibial veins.
• Distinguish from chronic thrombosis, which uses different codes.
• Code any associated pulmonary embolism separately, if documented.
