Superficial thrombophlebitis in pregnancy, unsp trimester

This code signifies the presence of inflammation and clotting in a superficial vein, specifically occurring during pregnancy, without specifying the trimester. It typically affects veins close to the skin surface, often in the legs, and is characterized by pain, tenderness, redness, and a palpable cord-like structure along the affected vein.

Use this code when documentation clearly indicates superficial thrombophlebitis in a pregnant patient, and the specific trimester is not recorded or is unknown. This diagnosis is supported by physician notes detailing the characteristic signs and symptoms of superficial thrombophlebitis in the context of pregnancy.

• Always attempt to identify and code the specific trimester of pregnancy if documented, using more specific O22.2x codes.
• Do not confuse with deep vein thrombosis (DVT), which involves deeper veins and carries different management and coding implications.
• Ensure the documentation explicitly states "superficial thrombophlebitis" to support this code.
