Suprvsn of preg w hx of in utero proc dur prev preg, 1st tri

This code signifies the medical oversight of a current pregnancy in a patient who previously underwent an in utero procedure during a prior gestation. It specifically applies when the current pregnancy is in its first trimester. This indicates a heightened level of surveillance due to a historical fetal intervention.

This code is appropriate for encounters involving a pregnant patient in her first trimester who has a documented history of an in utero procedure (e.g., fetal surgery, laser ablation for twin-to-twin transfusion syndrome) from a previous pregnancy. Documentation should clearly state the prior in utero intervention and the current gestational age.

• Always confirm the trimester of the current pregnancy; this code is specific to the first trimester.
• Do not confuse this with supervision of a current pregnancy where an in utero procedure is being performed or considered.
• Ensure the medical record explicitly states a "history of" an in utero procedure from a previous pregnancy.
