Superficial thrombophlebitis in pregnancy, first trimester

This code signifies the presence of inflammation and clotting in a superficial vein, specifically occurring during the first trimester of pregnancy. It typically affects veins close to the skin surface, often in the legs, and is characterized by localized pain, redness, and tenderness.

Use this code when documentation clearly indicates a diagnosis of superficial thrombophlebitis in a pregnant patient who is in her first trimester. Supporting documentation should include physician notes detailing the diagnosis and the gestational period.

• Ensure the documentation explicitly states "superficial" thrombophlebitis to differentiate from deep vein thrombosis.
• Verify the trimester of pregnancy is clearly documented; this code is specific to the first trimester.
• Do not use this code for thrombophlebitis unrelated to pregnancy or for deep vein thrombosis.
