Thrombophlebitis migrans

This code represents thrombophlebitis migrans, a rare condition characterized by recurrent, migratory episodes of superficial venous inflammation and thrombosis. These episodes typically affect veins in various locations, often appearing, resolving, and reappearing in different sites over time.

Use this code when documentation clearly indicates a diagnosis of thrombophlebitis migrans, also known as Trousseau's syndrome or migratory superficial thrombophlebitis. This diagnosis is often associated with underlying malignancy, particularly adenocarcinomas.

• Ensure documentation specifies the "migratory" nature of the thrombophlebitis to differentiate from localized superficial thrombophlebitis.
• Always code any associated underlying malignancy first, as thrombophlebitis migrans is frequently a paraneoplastic syndrome.
• Do not confuse with deep vein thrombosis (DVT) or other forms of thrombophlebitis that are not migratory.
