Superficial thrombophlebitis in pregnancy, third trimester

This code signifies the presence of inflammation and clotting in a superficial vein during the third trimester of pregnancy. It typically affects veins close to the skin surface, often in the lower extremities, and is characterized by localized pain, redness, and tenderness. This condition is distinct from deep vein thrombosis (DVT).

Apply this code when documentation explicitly states superficial thrombophlebitis occurring in a pregnant patient during her third trimester. Supporting documentation should include a physician's diagnosis of superficial thrombophlebitis and confirmation of the gestational trimester. This code is appropriate for both new diagnoses and exacerbations of pre-existing superficial thrombophlebitis during this specific pregnancy stage.

• Ensure the documentation clearly specifies "superficial" thrombophlebitis to differentiate from deep vein thrombosis.
• Verify the gestational trimester is explicitly documented as "third trimester" to avoid miscoding.
• Do not use this code if the thrombophlebitis is in a deep vein; instead, refer to codes for DVT in pregnancy.
