Supervision of high-risk pregnancy with history of trophoblastic disease

This code signifies a pregnancy that is being closely monitored due to a patient's prior history of trophoblastic disease, such as a hydatidiform mole or choriocarcinoma. The previous condition elevates the risk of complications in the current pregnancy, necessitating specialized care and surveillance.

Apply this code when a pregnant patient presents for prenatal care and has a documented history of gestational trophoblastic disease. It is used to indicate the high-risk nature of the current pregnancy due to this specific antecedent condition, guiding appropriate management and billing for increased surveillance.

• Always link this code to the appropriate code for the current pregnancy (e.g., V22.x or V23.x for normal or other high-risk pregnancies).
• Ensure the patient's medical record clearly documents the history of trophoblastic disease and the rationale for high-risk supervision.
• Do not use this code if the patient has active trophoblastic disease; instead, code the specific malignancy.
