Official Description

Ultrasound, spinal canal and contents

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

An ultrasound examination of the spinal canal and its contents, designated by CPT® Code 76800, is a diagnostic imaging procedure that utilizes high-frequency sound waves to visualize internal structures of the body. This non-invasive technique is particularly effective in assessing the spinal canal in newborns and infants, where the spine has minimal ossification, allowing for clearer imaging. The ultrasound works by emitting sound waves that penetrate the body and reflect off various tissues, with the returning echoes being captured and converted into visual images displayed on a monitor. This method is advantageous in pediatric patients due to the shorter distance between the skin surface and the spinal subarachnoid space, facilitating better visualization. While spinal ultrasound can also be employed intraoperatively in adults and older children, its diagnostic efficacy is limited in these populations. During the procedure, the patient is typically positioned prone, with the neck flexed to optimize access to the spinal area. Acoustic coupling gel is applied to the skin to enhance sound wave transmission. A linear probe is then used to examine the spinal canal and its contents in both sagittal and axial planes, ensuring a comprehensive evaluation along the entire length of the spine. Following the examination, the physician analyzes the captured images and provides a detailed written interpretation of the findings.

1. Indications

The ultrasound examination of the spinal canal and contents, as described by CPT® Code 76800, is indicated for specific clinical scenarios, particularly in pediatric populations. The following conditions may warrant this procedure:

  • Evaluation of Spinal Pathologies This procedure is often performed to assess for potential abnormalities within the spinal canal, such as cysts, tumors, or other structural anomalies that may affect the spinal cord or surrounding tissues.
  • Assessment of Hydrocephalus In infants, spinal ultrasound can be utilized to evaluate conditions like hydrocephalus, where there is an accumulation of cerebrospinal fluid (CSF) within the ventricles of the brain, which may also impact the spinal canal.
  • Investigation of Neurological Symptoms The procedure may be indicated in cases where infants present with unexplained neurological symptoms, allowing for a non-invasive assessment of the spinal canal and its contents.
  • Monitoring of Spinal Development Ultrasound can be used to monitor the development of the spinal canal in newborns and infants, particularly in those with known congenital conditions affecting spinal development.

2. Procedure

The procedure for conducting an ultrasound of the spinal canal and contents involves several key steps to ensure accurate imaging and assessment. The following outlines the procedural steps:

  • Patient Positioning The patient, typically a newborn or infant, is placed in a prone position on the examination table. This positioning allows optimal access to the spinal area for imaging.
  • Neck Flexion The neck of the patient is gently flexed to enhance the visibility of the spinal canal. This adjustment helps to create a better angle for the ultrasound probe to capture clear images of the spinal structures.
  • Application of Acoustic Coupling Gel A layer of acoustic coupling gel is applied to the skin along the spine. This gel is essential as it facilitates the transmission of sound waves from the ultrasound probe into the body, minimizing air gaps that could interfere with imaging.
  • Ultrasound Imaging A linear probe is utilized to examine the spinal canal and its contents. The physician moves the probe along the entire length of the spine, capturing images in both the sagittal and axial planes. This comprehensive approach ensures that all relevant areas are assessed for abnormalities.
  • Image Review and Interpretation After the imaging is completed, the physician reviews the captured images. A detailed written interpretation of the findings is then provided, summarizing any abnormalities or notable observations made during the examination.

3. Post-Procedure

Post-procedure care for patients undergoing an ultrasound of the spinal canal and contents is generally minimal due to the non-invasive nature of the examination. Patients can typically resume normal activities immediately following the procedure. The physician will review the ultrasound findings and discuss the results with the patient’s caregivers, providing any necessary follow-up recommendations based on the interpretation of the images. If any abnormalities are detected, further diagnostic testing or referrals to specialists may be suggested to address the identified issues. It is important for caregivers to monitor the patient for any unusual symptoms following the procedure and to maintain communication with the healthcare provider regarding any concerns.

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.
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.
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).
GC This service has been performed in part by a resident under the direction of a teaching physician
GV Attending physician not employed or paid under arrangement by the patient's hospice provider
SA Nurse practitioner rendering service in collaboration with a physician
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
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
XU Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service
