Suprvsn of preg w history of infertility, second trimester

This code signifies the ongoing medical oversight of a pregnancy in its second trimester (weeks 14 through 27) for a patient who has a documented history of infertility. It indicates that the patient's past difficulty conceiving is a factor influencing the management of the current pregnancy.

Apply this code when a pregnant patient, known to have a history of infertility, is receiving routine or specialized prenatal care during the second trimester. Documentation should clearly state the patient's infertility history and the current gestational age falling within the second trimester.

• Always sequence this code as a secondary diagnosis, following the code for the specific type of pregnancy (e.g., Z3A.xx for gestational age).
• Ensure the medical record explicitly states a history of infertility; a mere mention of "difficulty conceiving" without a formal diagnosis may not suffice.
• Do not confuse with codes for current infertility treatment or complications arising from infertility, as this code is for supervision of a successful pregnancy.
