Pregnancy Diagnosis Codes

Pregnancy codes document the full spectrum of maternal care, from routine prenatal visits to complications like gestational diabetes and preeclampsia. These codes are essential for insurance coverage of prenatal, delivery, and postpartum care.

About This Chapter

Chapter 15 of the ICD-10-CM classification covers pregnancy, childbirth and the puerperium, spanning codes O00-O9A. These codes are used by healthcare providers to document diagnoses in your electronic health record (EHR), on insurance claims, and on medical bills.

Why this matters: If you see a code starting with O on your medical bill or health records, it likely falls in this chapter. Understanding what chapter your code belongs to can help you make sense of your diagnosis and ask better questions at your next appointment.
