What This Code Means

A blood clot that has formed and persists in the left peroneal vein (vein in the lower leg on the left side).

Coding Tips

  • The '2' in the fifth position indicates left-sided involvement; verify documentation clearly identifies left peroneal vein.
  • Peroneal vein thrombosis may be less common than tibial vein thrombosis but should be coded accurately when present.

Clinical Significance

Chronic peroneal (fibular) vein thrombosis is a distal deep vein thrombosis that indicates a persistent clot in one of the paired veins running alongside the fibula. While peroneal vein thrombosis is a distal deep vein thrombosis, it can propagate to the popliteal vein and cause clinically significant post-thrombotic changes. Capturing this diagnosis accurately supports appropriate risk adjustment and reflects the patient's ongoing vascular disease management needs.

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., peroneal)
  • Documentation confirming left-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
