Suprvsn of preg w hx of in utero proc dur prev preg, 3rd tri

This code signifies the ongoing medical oversight of a current pregnancy where the patient has a documented history of having undergone an in utero procedure during a previous pregnancy. This supervision occurs specifically during the third trimester of the current gestation. It indicates a heightened level of monitoring due to the potential implications of the prior fetal intervention.

This code is appropriate when a pregnant patient in her third trimester is receiving antenatal care and her medical history clearly states a prior in utero procedure (e.g., fetal surgery, laser ablation for twin-to-twin transfusion syndrome) performed during a previous pregnancy. Documentation should specify the trimester of the current pregnancy and the history of the in utero procedure.

• Do not confuse this with supervision for an in utero procedure performed during the current pregnancy.
• Ensure the documentation explicitly states "third trimester" for the current pregnancy.
• This code is for supervision only; additional codes for any complications or specific conditions requiring the in utero procedure in the previous pregnancy may be relevant for historical context but are not coded with this specific supervision code.
