Maternity Obstetrical Care

Giving birth to a baby is one of the most exciting and overwhelming moments in a woman’s life. However, for healthcare providers, ensuring that their patients receive the best care during their pregnancy and childbirth can be a complex and challenging process, especially when it comes to billing and coding for their services. In this article, we will provide a comprehensive guide to maternity obstetrical care medical billing and coding.


Given the growing complexity of the healthcare system, medical billing and coding for maternity and obstetrical care services can be difficult procedures for healthcare professionals. The success of a practice and the satisfaction of patients depend on accurate and timely billing and coding. It will be crucial for healthcare providers to keep up with the most recent rules and codes in 2023–2024 due to changes in the medical billing and coding landscape.

Understanding Maternity Obstetrical Care

Maternity obstetrical care refers to the medical care given to a pregnant woman from the time of conception to childbirth. Obstetrical care includes prenatal care, delivery, and postpartum care. Prenatal care includes regular check-ups, ultrasounds, and other medical tests to monitor the health of the mother and the developing fetus. Delivery involves the actual birth of the baby, which can be vaginal or via a cesarean section (C-section). Postpartum care includes the medical care given to the mother after childbirth, including check-ups, counseling, and other support services.

Common Obstetrical Procedures and CPT Codes

In maternity obstetrical care, there are several common procedures that healthcare providers perform. Understanding the CPT codes associated with these procedures is essential for accurate billing and coding. Some of the most common obstetrical procedures and their corresponding CPT codes are as follows:

Vaginal Delivery CPT Code

Vaginal delivery is a common procedure in maternity obstetrical care and several CPT codes are used for billing for this service.  The primary CPT code associated with vaginal delivery is 59400. This code covers the routine obstetrical care provided during vaginal delivery, including:

  • Antepartum care
  • Admission to the labor and delivery room
  • Management of uncomplicated labor
  • Delivery of the baby
  • Delivery of the placenta
  • Postpartum care

 Additional codes may be used for services such as fetal monitoring, anesthesia, and episiotomy repair. These codes include 59025, 01967, and 59409, respectively.

C-Section CPT Code

Cesarean section (C-section) is a surgical method of delivery that is used when vaginal delivery is not possible or safe. There are several CPT codes used to bill for C-section services, including 59510, which covers the delivery of the fetus through an abdominal incision. This code covers the routine obstetrical care provided during C-section, including:

  • Antepartum care
  • Admission to the operating room
  • Surgical delivery of the baby
  • Surgical delivery of the placenta
  • Postpartum care

The other code 59618, covers the delivery of the fetus through a lower uterine segment incision. Additional codes may be used for services such as fetal monitoring, anesthesia, and wound closure.

Understanding CMS-1500 Claim Form

In order to get paid for their services, healthcare facilities typically send a bill via the CMS-1500 claim form to Medicare and other insurance companies. To ensure that claims are processed accurately and quickly when submitting for pregnancy and obstetrical care services, it is crucial to make sure the form is precise and full of all relevant information, including patient demographics, diagnostic codes, and CPT codes.

Key Components of OB/GYN Billing Practices
