Suprvsn of preg with history of ectopic preg, third tri

This code signifies the ongoing medical oversight of a pregnant patient who has a documented history of an ectopic pregnancy and is currently in her third trimester. It indicates that the current pregnancy is being carefully monitored due to the increased risk associated with a prior ectopic gestation.

Apply this code when a pregnant patient, known to have a history of ectopic pregnancy, presents for routine or specialized prenatal care during her third trimester. Documentation should clearly state the patient's history of ectopic pregnancy and the current gestational age falling within the third trimester.

• Always sequence this code as a secondary diagnosis, following the code for the current pregnancy (e.g., Z3A.xx for gestational age).
• Ensure the medical record explicitly documents the history of ectopic pregnancy and the current trimester.
• Do not confuse with codes for current ectopic pregnancy (O00.x) or supervision of high-risk pregnancy due to other factors.
