Official Description

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

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

A real-time transabdominal obstetrical ultrasound, designated by CPT® Code 76805, is a diagnostic imaging procedure performed on a pregnant uterus to evaluate both fetal and maternal health after the first trimester, specifically at or beyond 14 weeks of gestation. This ultrasound technique utilizes high-frequency sound waves to create images of the fetus and the surrounding structures within the mother's pelvis. The procedure is essential for assessing various aspects of fetal development and maternal well-being. It helps establish the viability of the fetus, identifies the presence of multiple gestations, and determines fetal age through precise measurements. Additionally, the ultrasound evaluates the position of the fetus and placenta, surveys fetal anatomy—including critical structures such as the brain, spine, abdomen, and heart—and assesses the umbilical cord insertion site and amniotic fluid volume. The procedure requires the mother to have a full bladder, which aids in obtaining clearer images. During the ultrasound, acoustic coupling gel is applied to the lower abdomen, and a transducer is used to capture images by directing ultrasonic waves at the fetus and surrounding structures. The echoes from these waves are recorded to create detailed images, which are then reviewed by the physician for any abnormalities. A written interpretation of the findings is provided, ensuring comprehensive documentation of the procedure. CPT® Code 76805 is specifically utilized for a single gestation or the first gestation in cases of multiple pregnancies after the first trimester, while CPT® Code 76810 is designated for each additional gestation.

1. Indications

Ultrasound, CPT® Code 76805, is indicated for the following conditions and evaluations:

  • Establish Viability The procedure is performed to confirm the viability of the fetus during the second trimester of pregnancy.
  • Multiple Gestation Assessment It helps determine whether a multiple gestation exists, which is crucial for managing the pregnancy appropriately.
  • Fetal Age Determination The ultrasound is used to assess fetal age through accurate measurements of the fetus.
  • Fetal Position Evaluation It evaluates the position of the fetus and the placenta, which is important for planning delivery.
  • Fetal Anatomy Survey The procedure surveys fetal anatomy, including critical structures such as the intracranial area, spine, abdomen, and heart, with a four-chamber evaluation.
  • Umbilical Cord Insertion Site Identification It identifies the site of umbilical cord insertion, which can impact fetal health.
  • Amniotic Fluid Volume Evaluation The ultrasound assesses the volume of amniotic fluid, which is vital for fetal development.
  • Maternal Uterus and Adnexa Evaluation It evaluates the maternal uterus and adnexa, if visible, to ensure maternal health during pregnancy.

2. Procedure

The procedure for performing a transabdominal obstetrical ultrasound, CPT® Code 76805, involves several key steps:

  • Preparation of the Patient The mother is instructed to arrive with a full bladder, which enhances the quality of the ultrasound images. This is important as a full bladder provides better acoustic windows for visualization of the fetus and surrounding structures.
  • Application of Acoustic Coupling Gel Once the patient is positioned comfortably, acoustic coupling gel is applied to the skin of the lower abdomen. This gel eliminates air pockets between the transducer and the skin, allowing for better transmission of the ultrasound waves.
  • Transducer Placement The transducer is then pressed firmly against the skin of the lower abdomen. The sonographer or physician sweeps the transducer back and forth over the abdomen to capture images of the pregnant uterus and the fetus.
  • Image Acquisition As the transducer moves, it emits ultrasonic wave pulses directed at the fetus and surrounding pelvic structures. The echoes produced by these waves are recorded, creating real-time images of the fetus and maternal anatomy.
  • Evaluation of Images The physician reviews the obtained ultrasound images, assessing the fetus, pregnant uterus, and any visible maternal pelvic structures for abnormalities. This evaluation is critical for determining the health and development of both the fetus and the mother.
  • Documentation and Interpretation After the evaluation, the physician provides a written interpretation of the ultrasound findings, which is essential for medical records and further clinical decision-making.

3. Post-Procedure

After the completion of the ultrasound procedure, there are no specific post-procedure care requirements mentioned in the provided data. However, it is standard practice for the patient to be informed about the results of the ultrasound during a follow-up appointment. The physician may discuss any findings, potential concerns, or necessary follow-up actions based on the ultrasound results. The patient may resume normal activities immediately following the procedure unless otherwise advised by the healthcare provider.

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.
TC Technical component; under certain circumstances, a charge may be made for the technical component alone; under those circumstances the technical component charge is identified by adding modifier 'tc' to the usual procedure number; technical component charges are institutional charges and not billed separately by physicians; however, portable x-ray suppliers only bill for technical component and should utilize modifier tc; the charge data from portable x-ray suppliers will then be used to build customary and prevailing profiles
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.
