Supervision of pregnancy with history of ectopic pregnancy. This code is used for patients with a past ectopic pregnancy who are currently pregnant and require monitoring due to the increased risk of complications.

Example 1: A 28-year-old female presents for her first prenatal visit. She has a history of one previous ectopic pregnancy.An ultrasound confirms an intrauterine pregnancy at 6 weeks gestation.The code O09.1 is used to indicate the supervision of this high-risk pregnancy., A 35-year-old woman presents at 10 weeks gestation. She had an ectopic pregnancy two years ago that required surgical removal of the affected fallopian tube. Her current pregnancy is intrauterine and appears normal. O09.1 is used to document the ongoing supervision of her pregnancy., A woman who has had a previous ectopic pregnancy is now in her second trimester with a viable intrauterine pregnancy. She continues to receive regular prenatal care, including ultrasounds and blood tests, due to the increased risk associated with her history. Code O09.1 is applied to each prenatal visit.

Documentation should include details of the prior ectopic pregnancy, such as date, treatment, and any resulting complications. Confirmation of the current intrauterine pregnancy via ultrasound should also be documented. Regular prenatal care visits and monitoring should be recorded. If applicable, any complications arising from the current pregnancy should also be noted.
