Official Description

Ophthalmic ultrasonic foreign body localization

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Ophthalmic ultrasonic foreign body localization is a specialized non-invasive diagnostic procedure that employs high-frequency sound waves to visualize the internal structures of the eye. This technique utilizes a transducer probe, which is placed firmly against the closed eyelid, to emit sound waves that penetrate the eye and create a detailed gray scale image of its anatomy. The primary advantage of this method is its ability to detect radiolucent foreign bodies—objects that do not appear on standard X-ray or CT imaging—thereby providing critical information for diagnosis and treatment. During the procedure, the ultrasound not only identifies the size, shape, and precise location of the foreign body but also evaluates the extent of any intraocular trauma that may have occurred. This assessment is vital for determining the appropriate management strategy for the injury. The procedure involves applying ultrasonic conduction gel over the eyelid to enhance sound wave transmission, followed by scanning the eye in both sagittal and transverse planes. The fluid-filled nature of the eye allows for excellent acoustic properties, resulting in high-quality images. Additionally, both the affected and unaffected eye may be examined to facilitate comparison and enhance diagnostic accuracy.

1. Indications

Ophthalmic ultrasonic foreign body localization is indicated for the following conditions:

  • Suspected Intraocular Foreign Body Patients presenting with symptoms suggesting the presence of a foreign body within the eye, particularly when radiolucent materials are suspected.
  • Assessment of Intraocular Trauma Individuals who have experienced trauma to the eye, where there is a need to evaluate the extent and severity of the injury.
  • Comparison of Injured and Non-Injured Eye Cases where both eyes are scanned to provide a comparative analysis, aiding in the diagnosis and management of ocular conditions.

2. Procedure

The procedure for ophthalmic ultrasonic foreign body localization involves several key steps:

  • Preparation of the Patient The patient is positioned comfortably, and the eye undergoing examination is prepared by ensuring it is closed. Ultrasonic conduction gel is then applied over the eyelid to facilitate sound wave transmission.
  • Application of the Transducer Probe A transducer probe is placed firmly against the closed eyelid. This probe emits high-frequency sound waves that penetrate the eye structure.
  • Scanning the Eye The eye is scanned in both sagittal and transverse planes. This comprehensive scanning technique allows for detailed imaging of the eye's internal structures, enabling the identification of any foreign bodies present.
  • Image Acquisition The ultrasound machine captures the reflected sound waves, producing a gray scale image that reveals the anatomy of the eye, including the location, size, and shape of any foreign bodies.
  • Comparison Imaging If necessary, the non-injured eye may also be scanned to provide a baseline for comparison, enhancing the diagnostic process.

3. Post-Procedure

After the completion of the ophthalmic ultrasonic foreign body localization procedure, the patient may be monitored for any immediate reactions to the gel or discomfort. There are typically no significant recovery requirements, as the procedure is non-invasive and does not involve any surgical intervention. Patients can usually resume normal activities shortly after the procedure. However, follow-up care may be necessary depending on the findings of the ultrasound, particularly if a foreign body is detected or if there is evidence of intraocular trauma that requires further management.

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.
50 Bilateral procedure: unless otherwise identified in the listings, bilateral procedures that are performed at the same session, should be identified by adding modifier 50 to the appropriate 5 digit code. note: this modifier should not be appended to designated "add-on" codes (see appendix d).
79 Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.)
GC This service has been performed in part by a resident under the direction of a teaching physician
LT Left side (used to identify procedures performed on the left side of the body)
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
X4 Episodic/focused services: for reporting services by clinicians who provide focused care on particular types of treatment limited to a defined period and circumstance; the patient has a problem, acute or chronic, that will be treated with surgery, radiation, or some other type of generally time-limited intervention; reporting clinician service examples include but are not limited to, the orthopedic surgeon performing a knee replacement and seeing the patient through the postoperative period
