Official Description

Ultrasound, pregnant uterus, real time with image documentation, fetal and maternal evaluation plus detailed fetal anatomic examination, 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 76811, is a diagnostic imaging procedure performed to assess the pregnant uterus and the developing fetus. This ultrasound technique utilizes high-frequency sound waves to create images of the fetus and surrounding maternal structures, allowing for a comprehensive evaluation of both fetal and maternal health. The procedure is particularly focused on providing detailed anatomical insights into the fetus, which includes examining critical structures such as the brain, heart, limbs, and abdominal organs. The ultrasound is conducted with the patient having a full bladder, which enhances the clarity of the images obtained. During the procedure, acoustic coupling gel is applied to the skin of the lower abdomen to facilitate the transmission of sound waves. The transducer is then moved across the abdomen to capture real-time images, which are recorded for further analysis. The physician interprets these images to identify any potential abnormalities and documents the findings in a written report. This procedure is essential for establishing fetal viability, determining gestational age, and evaluating the position of the fetus and placenta, among other critical assessments. CPT® Code 76811 is specifically used for the first gestation in a multiple pregnancy, while additional gestations are coded separately with CPT® Code 76812.

1. Indications

Ultrasound, CPT® Code 76811, is indicated for various clinical scenarios during pregnancy. The following conditions and evaluations warrant the performance of this procedure:

  • Establishing Fetal Viability - To confirm that the fetus is alive and developing appropriately.
  • Determining Multiple Gestation - To assess whether there is more than one fetus present in the uterus.
  • Fetal Age Assessment - To estimate the gestational age of the fetus through specific fetal measurements.
  • Fetal Position Evaluation - To determine the position of the fetus within the uterus, which is crucial for planning delivery.
  • Placental Location Assessment - To evaluate the position and health of the placenta.
  • Surveying Fetal Anatomy - To conduct a detailed examination of fetal structures, including the brain, spine, abdomen, and heart.
  • Umbilical Cord Insertion Site Identification - To locate where the umbilical cord attaches to the placenta.
  • Amniotic Fluid Volume Evaluation - To assess the amount of amniotic fluid surrounding the fetus, which is important for fetal well-being.
  • Maternal Uterus and Adnexa Evaluation - To examine the maternal uterus and any visible adnexal structures for abnormalities.

2. Procedure

The procedure for performing an obstetric ultrasound using CPT® Code 76811 involves several key steps that ensure a thorough evaluation of the fetus and the pregnant uterus. The following outlines the procedural steps:

  • Preparation of the Patient - The patient is instructed to arrive with a full bladder, which helps improve the quality of the ultrasound images. This is crucial for obtaining clear views of the fetal and maternal structures.
  • Application of Acoustic Coupling Gel - A gel is applied to the skin of the lower abdomen. This gel acts as a medium to facilitate the transmission of sound waves from the transducer into the body.
  • Transducer Placement - The transducer, a handheld device that emits and receives ultrasound waves, is pressed firmly against the skin of the lower abdomen. The operator sweeps the transducer back and forth to capture images of the pregnant uterus and surrounding structures.
  • Image Acquisition - As the transducer moves, ultrasonic wave pulses are directed at the fetus and maternal structures. The echoes produced by these waves are recorded, creating real-time images that depict the anatomy and condition of the fetus and uterus.
  • Evaluation of Abnormalities - The images obtained are carefully analyzed for any potential abnormalities in fetal development or maternal health. This evaluation is critical for identifying any issues that may require further investigation or intervention.
  • Image Review and Interpretation - After the imaging is complete, the physician reviews the ultrasound images. A detailed interpretation is provided, documenting the findings and any concerns that may arise from the evaluation.

3. Post-Procedure

Following the completion of the ultrasound procedure, the patient may be advised on several post-procedure considerations. Typically, there are no specific restrictions or recovery protocols required after a routine obstetric ultrasound. The patient can resume normal activities immediately. However, the physician may discuss the findings of the ultrasound with the patient, including any necessary follow-up appointments or additional testing if abnormalities were detected. It is essential for the patient to understand the results and any implications for their pregnancy. Documentation of the ultrasound findings is provided in a written report, which may be shared with other healthcare providers involved in the patient's care.

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.
GC This service has been performed in part by a resident under the direction of a teaching physician
22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
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.
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.
