Acute embolism and thrombosis of right peroneal vein

This code signifies the sudden blockage of the right peroneal vein by an embolus (a traveling clot) or a thrombus (a stationary clot). This condition is a form of deep vein thrombosis (DVT) affecting a specific vein in the lower leg. It indicates an acute, rather than chronic, event.

Use this code for patients presenting with new onset symptoms such as pain, swelling, and tenderness in the right lower leg, where diagnostic imaging (e.g., ultrasound, venography) confirms an acute thrombus or embolus within the right peroneal vein. Documentation should clearly specify the acute nature and the affected vein.

• Ensure documentation specifies "acute" and the "right peroneal vein" to support this specific code.
• Do not confuse with chronic venous thrombosis or embolism, which have different code assignments.
• Consider sequencing this code as a primary diagnosis when it is the reason for the encounter, or as a secondary diagnosis if it's a co-morbidity being managed.
