Chronic embolism and thrombosis of right tibial vein

This code signifies a persistent blockage within the right tibial vein, caused by either an embolus (a traveling clot) or a thrombus (a stationary clot). This condition is long-standing, indicating it has developed over time rather than being an acute event. It specifically affects the deep veins of the lower leg on the right side.

This code is appropriate when documentation clearly states a chronic deep vein thrombosis (DVT) or embolism affecting the right tibial vein. It should be used when the physician explicitly diagnoses a chronic condition, often supported by imaging studies showing an older or organized clot.

• Ensure the documentation specifies "chronic" to differentiate from acute events.
• Verify the laterality (right) and the specific vessel (tibial vein) are clearly documented.
• Do not use for superficial thrombophlebitis; this code is for deep vein involvement.
