Suprvsn of preg with history of ectopic preg, second tri

This code signifies ongoing prenatal care for a pregnant patient who has a documented history of an ectopic pregnancy, and is currently in her second trimester. It indicates that the patient requires specialized monitoring due to the increased risk associated with her past ectopic pregnancy.

Apply this code when a pregnant patient, currently between 14 weeks 0 days and 27 weeks 6 days gestation, is receiving routine or enhanced prenatal supervision and has a history of a previous ectopic pregnancy. Documentation should clearly state the patient's gestational age and the history of ectopic pregnancy.

• Always sequence this code as a secondary diagnosis following the primary code for the current pregnancy (e.g., Z3A.xx for gestational age).
• Do not use this code if the current pregnancy is ectopic; instead, use codes from category O00.
• Ensure the medical record explicitly states "history of ectopic pregnancy" and the current trimester.
