CPT Code 76801 is the billing code used for a complete transabdominal pregnancy ultrasound. This code applies when a provider performs a detailed evaluation of the uterus, gestational sac, embryo/fetus, adnexa, and pelvic structures during the first trimester of pregnancy.

In 2025, correct documentation of CPT 76801 is more critical than ever due to payer audits, compliance checks, and the rise of AI-driven claim scrubbing systems. Healthcare providers and billing managers need to understand when and how to use this code to ensure proper reimbursement and avoid denials.

What Is CPT Code 76801?

CPT 76801 refers to a limited ultrasound of the pregnant uterus to assess specific, immediate concerns. It’s not a comprehensive exam and is often used for:

  • Confirming fetal viability (e.g., checking for a heartbeat).
  • Verifying fetal position (e.g., breech vs. vertex).
  • Evaluating amniotic fluid levels (qualitative, not quantitative).
  • Assessing placental location (e.g., ruling out placenta previa).

CPT Code 76801 Description

According to the AMA CPT guidelines, 76801 is defined as:

Ultrasound, pregnant uterus, real-time with image documentation, fetal and maternal evaluation, first trimester (less than 14 weeks 0 days), transabdominal approach; single or first gestation.

This code covers a complete first-trimester ultrasound, not a limited or follow-up exam.

When to Use CPT 76801

You should report CPT 76801 when:

  • Performing a first-trimester, complete pregnancy ultrasound (before 14 weeks).
  • Evaluating fetal heartbeat, number of fetuses, gestational sac, yolk sac, uterus, ovaries, and adnexa.
  • Conducting the scan via a transabdominal approach.

Common Scenarios:

  • Confirmation of early pregnancy.
  • Dating and viability of pregnancy.
  • Evaluation of abnormal bleeding.
  • Suspected ectopic or abnormal intrauterine pregnancy.

Related Ultrasound CPT Codes

Understanding the differences between related codes prevents denials and duplicate billing:

  • CPT Code 76817 – Transvaginal ultrasound of pregnant uterus.
  • CPT Code 76813 – Nuchal translucency measurement (first-trimester).
  • CPT Code 76802 – Each additional gestation (add-on to 76801).
  • CPT Code 76805 – Second or third trimester complete pregnancy ultrasound.

Tip: Providers often ask, “Can CPT 76801 and 76817 be billed together?” The answer: Yes, but only if both transabdominal (76801) and transvaginal (76817) studies are performed for a distinct medical necessity. Documentation must clearly support both.

Documentation Requirements for CPT 76801

To avoid denials, documentation should include:

  • Reason for the ultrasound (clinical indication).
  • Gestational age and trimester.
  • Findings on fetal heartbeat, number of fetuses, gestational sac, yolk sac, uterus, adnexa.
  • Image retention as per payer and compliance rules.

Frequently Asked Questions (FAQs)

CPT Code 76801 is used to report a complete obstetrical ultrasound performed in the first trimester of pregnancy. It includes a detailed evaluation of the uterus, gestational sac, embryo/fetus, crown-rump length, yolk sac, and maternal adnexa (ovaries and surrounding structures), including Trans abdominal or transvaginal approach.

Even though some confusion, CPT 76801 is for a whole obstetric ultrasound in the first trimester. If only a limited assessment is done (e.g., fetal heartbeat or position), CPT 76815 is the correct code. Choosing the right code depends on the scope of the exam and documentation.

  • Use 76801 for a whole first-trimester ultrasound via the Trans abdominal methodology.
  • Use 76817 for a transvaginal ultrasound typically performed in early pregnancy or to assess issues like bleeding.
    Sometimes both are performed in the same session; in that case, documentation must support the use of both codes with appropriate modifiers (e.g., modifier 59).

Yes, CPT 76801 is typically covered by insurance and Medicare when medically necessary and properly documented. It must meet clinical indications like dating the pregnancy, confirming viability, or evaluating suspected ectopic pregnancy. Always check the payer’s coverage policy and include relevant ICD-10 codes such as Z34.80 (Encounter for supervision of normal pregnancy).

Generally, 76801 is billed only once per pregnancy for the first-trimester evaluation. For follow-up or repeat ultrasounds, providers should use codes like 76815 (limited) or 76816 (follow-up). Repeating 76801 without clinical necessity may result in claim denials or payer audits.

To support billing CPT 76801, providers must include:

  • Gestational sac evaluation
  • Fetal heartbeat presence
  • Crown-rump length or gestational age estimation
  • Maternal adnexa assessment
  • Uterus and cervix evaluation
    the report should specify the type of ultrasound (Trans abdominal/transvaginal) and clearly state the findings. Accurate and complete documentation is essential for compliance and reimbursement.
