Suprvsn of preg with history of ectopic preg, unsp trimester

This code signifies ongoing prenatal care for a pregnant patient who has a documented history of an ectopic pregnancy. It indicates that the current pregnancy is being monitored with this specific historical risk factor in mind, without specifying the current trimester.

Apply this code when a pregnant patient presents for routine or specialized prenatal care and their medical history clearly indicates a previous ectopic gestation. Documentation should explicitly state the history of ectopic pregnancy and the current pregnancy's supervision.

• Do not use this code if the current pregnancy is ectopic; instead, use codes from the O00 category.
• This code is for supervision of a current intrauterine pregnancy in a patient with a past ectopic pregnancy.
• Always sequence this code as a secondary diagnosis, following the code for the current pregnancy's trimester (e.g., O09.90, O09.11-O09.19).
