Acute embolism and thrombosis of left popliteal vein

This code signifies the sudden blockage of the left popliteal vein by an embolus (a traveling clot) or a thrombus (a stationary clot). This acute vascular event obstructs blood flow in the deep venous system of the left lower extremity, typically leading to symptoms such as pain, swelling, and warmth in the calf or behind the knee.

Apply this code when documentation explicitly states an acute embolism or thrombosis affecting the left popliteal vein. This diagnosis is often confirmed by imaging studies such as duplex ultrasound or venography, demonstrating an acute occlusive process in this specific vessel.

• Ensure laterality (left) is clearly documented. Do not use for unspecified or right-sided involvement.
• Distinguish between acute and chronic conditions; this code is specific to acute presentations.
• Consider sequencing with any underlying conditions contributing to the thrombosis, such as hypercoagulable states or malignancy.
