Superficial thrombophlebitis in pregnancy, second trimester

This code signifies the presence of inflammation and clotting in a superficial vein, typically in the legs, occurring during the second trimester of a pregnancy. It describes a non-life-threatening venous condition distinct from deep vein thrombosis (DVT).

Apply this code when documentation explicitly states superficial thrombophlebitis in a pregnant patient who is currently in her second trimester. Supporting documentation would include physician notes detailing the diagnosis, the affected superficial vein, and the gestational age or trimester.

• Ensure the documentation clearly specifies "superficial" thrombophlebitis to differentiate from DVT.
• Verify the trimester of pregnancy is explicitly stated as the second trimester; avoid assuming based on dates alone.
• Do not use this code if the thrombophlebitis is deep vein or if the pregnancy is in a different trimester.
