Official Description

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

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

A real-time transabdominal obstetrical ultrasound, designated by CPT® Code 76801, is a diagnostic imaging procedure performed during the first trimester of pregnancy, specifically when the gestational age is less than 14 weeks 0 days. This ultrasound is crucial for evaluating both the fetus and the pregnant uterus, as well as the surrounding pelvic structures of the mother. The procedure aims to establish the viability of the embryo or fetus, assess the presence of multiple gestations, and determine fetal age through precise measurements of the gestational sac and fetus. Additionally, it allows for the evaluation of the position of the fetus and placenta, the anatomical structures of the fetus and placenta, and the volume of amniotic fluid. During the procedure, the mother is typically required to present with a full bladder, which enhances the clarity of the ultrasound images. The application of acoustic coupling gel to the skin of the lower abdomen facilitates the transmission of ultrasonic waves. A transducer is then firmly pressed against the skin and moved back and forth over the lower abdomen to capture images of the pregnant uterus, the fetus, and the surrounding pelvic structures. The ultrasound utilizes high-frequency sound waves that are directed at these areas, and the echoes produced are recorded to create visual images. Any abnormalities detected during the examination are thoroughly evaluated. Following the procedure, the physician reviews the obtained ultrasound images and provides a comprehensive written interpretation of the findings. This code, 76801, is specifically utilized for a single gestation or the first gestation in cases of multiple pregnancies during the first trimester, while code 76802 is designated for each additional gestation.

1. Indications

The ultrasound procedure designated by CPT® Code 76801 is indicated for the following conditions and evaluations during the first trimester of pregnancy:

  • Establishing Viability - To confirm the presence of a viable embryo or fetus within the pregnant uterus.
  • Multiple Gestation Assessment - To determine if there is more than one fetus present in the uterus.
  • Fetal Age Determination - To assess the gestational age by measuring the gestational sac and fetal structures.
  • Fetal and Placental Position Evaluation - To evaluate the position of the fetus and the placenta within the uterus.
  • Anatomical Structure Evaluation - To assess visible anatomical structures of the fetus and placenta for any abnormalities.
  • Amniotic Fluid Volume Assessment - To evaluate the volume of amniotic fluid surrounding the fetus.
  • Maternal Uterus and Adnexa Evaluation - To assess the maternal uterus and surrounding adnexal structures for any abnormalities.

2. Procedure

The procedure for performing a transabdominal obstetrical ultrasound as per CPT® Code 76801 involves several key steps:

  • Preparation of the Patient - The patient is instructed to arrive with a full bladder, which is essential for optimal imaging. This is typically achieved by having the patient drink a specified amount of water prior to the examination.
  • Application of Acoustic Coupling Gel - Once the patient is positioned comfortably, a conductive gel is applied to the skin of the lower abdomen. This gel serves to enhance the transmission of ultrasound waves and improve image quality.
  • Transducer Placement - A transducer, which is the device that emits and receives ultrasound waves, is firmly pressed against the skin over the lower abdomen. The sonographer or physician will move the transducer back and forth across the area to capture images.
  • Image Acquisition - As the transducer is moved, it emits high-frequency sound waves that penetrate the body and reflect off internal structures. The echoes produced are converted into real-time images displayed on a monitor, allowing for the evaluation of the fetus, uterus, and surrounding pelvic structures.
  • Evaluation of Findings - The physician reviews the obtained images for any signs of abnormalities, such as issues with fetal development, placental placement, or uterine conditions. This evaluation is critical for determining the health of both the fetus and the mother.
  • Documentation and Interpretation - After the imaging is complete, the physician provides a written interpretation of the ultrasound findings, which is documented in the patient's medical record. This report may include details about fetal viability, gestational age, and any identified abnormalities.

3. Post-Procedure

After the completion of the ultrasound procedure, the patient may be advised to resume normal activities unless otherwise instructed by the physician. There are typically no specific post-procedure care requirements associated with this ultrasound. However, the patient may be informed about the next steps based on the findings of the ultrasound, including any necessary follow-up appointments or additional testing if abnormalities are detected. The physician will discuss the results with the patient, providing clarity on the health status of the fetus and any implications for the pregnancy moving forward.

26 Professional component: certain procedures are a combination of a physician or other qualified health care professional component and a technical component. when the physician or other qualified health care professional component is reported separately, the service may be identified by adding modifier 26 to the usual procedure number.
X5 Diagnostic services requested by another clinician: for reporting services by a clinician who furnishes care to the patient only as requested by another clinician or subsequent and related services requested by another clinician; this modifier is reported for patient relationships that may not be adequately captured by the above alternative categories; reporting clinician service examples include but are not limited to, the radiologist's interpretation of an imaging study requested by another clinician
CR Catastrophe/disaster related
52 Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
76 Repeat procedure or service by same physician or other qualified health care professional: it may be necessary to indicate that a procedure or service was repeated by the same physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 76 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
77 Repeat procedure by another physician or other qualified health care professional: it may be necessary to indicate that a basic procedure or service was repeated by another physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 77 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
AQ Physician providing a service in an unlisted health professional shortage area (hpsa)
