Contrary to other areas of the American Medical Association, Current Procedural Terminology, maternity, and obstetrical treatment have unique coding and billing requirements (CPT). “Global OB Care” refers to the full spectrum of prenatal, labor and delivery, and postpartum services for expectant mothers.

Global OB care is documented using the correct CPT code when the same group of doctors and other medical providers performs all parts of the OB package. Traditional antenatal care, labor and delivery, and postpartum care are all included in maternity services. The provider may: Based on the patient’s situation and insurance provider:

  • Submit one CMS-1500 claim form covering all nine months of care for full-term deliveries.
  • Send in claims for maternity care services that are itemized. (Most state Medicaid payers demand claim submission for each visit.)

Let’s discuss what you should know about medical billing for obstetric care throughout pregnancy.

Universal OB/GYN Billing Codes

  • 59400 – Antenatal care, vaginal birth (with or without episiotomy and forceps), and postnatal care are all part of the standard obstetrical care routine.

Medical billing for OB-GYN ultrasound

For reporting ultrasound operations, adhering to all OBGYN medical billing and coding regulations for care during pregnancy is crucial.  Each coded process should have corresponding pictures available for scrutiny, showing the relevant anatomy and pathology. CPT specifies neither the number of required photographs nor their storage method.

There may be a need for adjustments if more than one fetus is present or if different operations are being carried out on the same patient during the same visit. Getting a claim line denied for reporting a wrong modifier is possible. Below are several CPT codes used to describe various ultrasound recordings. Ensure that your clinic follows the correct reporting rules for each CPT code.

  • 76801–76810: Mother and fetus assessment (Transabdominal Approach, By Trimester)
  • 76811–76812: Superior and In-Depth Analysis of the Fetus’ Anatomy
  • 76813–76814: Measuring of Fetal Nuchal Translucency
  • 76818–76819: Prenatal Biophysical Profile
  • 76815: Limited Investigation Using Trans-Abdominal Ultrasonography
  • 59025: Fetal Non-Stress Examination
  • 76816: Follow-Up Investigation Using Transabdominal Ultrasound  76817: Investigation of transvaginal ultrasound


When medically billing for maternity and obstetrical care, it’s crucial to consider all nine months of service provided. You must pay particular attention to the Global OB Package. The CPT rules must be strictly followed, with the correct diagnosis appended, the doctor’s documentation of prenatal, natal, and postnatal care, and any necessary changes to the modifier.
