Thrombophlebitis migrans

This code describes a rare, recurrent, and migratory superficial thrombophlebitis, often affecting various venous segments over time. It is characterized by tender, erythematous, palpable cords that appear, resolve, and reappear in different locations, typically without an identifiable underlying cause.

Assign this code when documentation clearly indicates a diagnosis of thrombophlebitis migrans, also known as migratory superficial thrombophlebitis. This diagnosis is often made based on the characteristic clinical presentation of recurring and shifting inflammatory venous lesions.

• Differentiate from other forms of thrombophlebitis (e.g., deep vein thrombosis, superficial thrombophlebitis of a specific site) which have distinct codes.
• Review documentation for the migratory nature of the condition to ensure accurate code assignment.
• Consider co-occurring conditions, as thrombophlebitis migrans can sometimes be associated with underlying malignancies (Trousseau's syndrome) or autoimmune disorders, and code those conditions separately if documented.
