What This Code Means

A blood clot that has formed in the right popliteal vein (a major vein behind the knee) and has persisted over time, potentially blocking blood flow in the leg. This is a chronic condition meaning it has developed gradually or persisted for an extended period.

Coding Tips

•Verify the laterality (right vs. left) is clearly documented in the medical record before assigning this code
•Confirm the thrombosis is documented as chronic rather than acute, as acute popliteal vein thrombosis uses different ICD-10 codes (I82.51-)

Clinical Significance

Chronic popliteal vein thrombosis involves a persistent clot in the major vein behind the knee, which serves as the transition point between proximal and distal deep venous systems. This location is clinically significant because popliteal vein thrombosis carries meaningful risk of post-thrombotic syndrome and may impair venous return from the entire lower leg. Accurate documentation of chronic popliteal vein thrombosis is important for capturing vascular disease complexity in risk adjustment.

Documentation Requirements

✓Provider documentation explicitly stating 'chronic' deep vein thrombosis (not assumed from duration of treatment)
✓Clinical evidence supporting the diagnosis such as duplex ultrasound, venography, or other imaging results
✓Specific vein location documented (e.g., popliteal)
✓Documentation confirming right-sided laterality
✓Current treatment plan including anticoagulation therapy and duration
✓Assessment and monitoring notes demonstrating the condition is being actively managed
✓Documentation of chronicity such as 'chronic,' 'old,' 'long-standing,' or history of prior acute deep vein thrombosis that has transitioned to chronic status

Commonly Confused Codes

I82.431 — Acute embolism and thrombosis of popliteal vein; verify documentation states chronic, not acute I82.54- — Chronic embolism and thrombosis of tibial vein; the tibial vein is more distal than the popliteal; confirm exact location I82.51- — Chronic embolism and thrombosis of femoral vein; the femoral vein is more proximal than the popliteal; confirm anatomical site I87.01- — Postthrombotic syndrome; may develop as a complication of chronic popliteal vein thrombosis and should be coded separately
