Suprvsn of preg w hx of in utero proc dur prev preg, 2nd tri

This code signifies the ongoing medical oversight of a current pregnancy in a patient who previously underwent an in-utero procedure during an earlier pregnancy. It specifically applies when the current pregnancy is in the second trimester. This indicates a heightened level of surveillance due to the potential risks or complications associated with a prior fetal intervention.

This code is used when a pregnant patient, currently in her second trimester, has a documented history of a fetal surgical or diagnostic intervention (e.g., fetal shunt placement, laser photocoagulation for twin-to-twin transfusion syndrome, amniocentesis with intervention) during a previous pregnancy. Documentation should clearly state the history of the in-utero procedure and the current gestational age.

• Always sequence this code as a secondary diagnosis, with the primary code indicating the reason for the current encounter (e.g., routine prenatal visit, specific complication).
• Ensure the medical record explicitly states "history of in-utero procedure" and the current pregnancy's trimester.
• Do not confuse this with codes for current pregnancy complications or procedures; this code specifically refers to a history from a previous pregnancy.
