Testicular imaging with vascular flow

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Testicular imaging with vascular flow, as defined by CPT® Code 78761, is a diagnostic procedure that utilizes scintigraphy in conjunction with a radiolabeled isotope tracer to assess the vascular perfusion of the testis. This imaging technique is particularly valuable in identifying conditions such as spermatic cord torsion, which is a surgical emergency, as well as epididymitis and orchitis, which are inflammatory conditions of the epididymis and testis, respectively. The procedure begins with the establishment of an intravenous line, through which the radiolabeled isotope tracer is injected into the patient's circulatory system. Following the injection, the patient is positioned on a procedure table, and a gamma camera is strategically placed to capture images of the scrotal area. The imaging process involves obtaining flow studies that document the blood supply to the testis, which can be visualized in cinematic mode, followed by the acquisition of static images that detail the testis, spermatic cords, and surrounding structures. The emitted radioactive energy from the tracer is transformed into visual images, which are then interpreted by the physician, who subsequently generates a comprehensive written report detailing the findings of the study.

1. Indications

The procedure of testicular imaging with vascular flow is indicated for the evaluation of specific conditions affecting the testicular region. These indications include:

  • Spermatic Cord Torsion - A critical condition where the spermatic cord becomes twisted, compromising blood flow to the testis, which requires prompt diagnosis and intervention.
  • Epididymitis - An inflammation of the epididymis, often caused by infection, which can lead to pain and swelling in the scrotal area.
  • Orchitis - Inflammation of the testis, which may be due to viral or bacterial infections, and can result in testicular pain and swelling.

2. Procedure

The testicular imaging with vascular flow procedure involves several critical steps to ensure accurate imaging and diagnosis. The steps are as follows:

  • Step 1: Establishing Intravenous Access - The procedure begins with the placement of an intravenous line to facilitate the administration of the radiolabeled isotope tracer. This step is essential for ensuring that the tracer is delivered directly into the patient's circulatory system, allowing for effective imaging of the testicular blood flow.
  • Step 2: Injection of Radiolabeled Isotope Tracer - Once the intravenous line is established, the radiolabeled isotope tracer is injected. This tracer is crucial for the scintigraphy process, as it emits radioactive energy that will be captured during imaging.
  • Step 3: Patient Positioning - After the injection, the patient is positioned on the procedure table. Proper positioning is vital to ensure that the gamma camera can effectively capture images of the scrotal area, focusing on the testis and spermatic cords.
  • Step 4: Imaging with Gamma Camera - The gamma camera is then utilized to perform flow studies, which document the vascular perfusion of the testis. These studies may be displayed in cinematic mode, allowing for dynamic visualization of blood flow, followed by the acquisition of static images that provide detailed views of the testis and surrounding structures.
  • Step 5: Interpretation and Reporting - The radioactive energy emitted from the tracer is converted into images that are analyzed by the physician. The physician interprets the findings and compiles a written report that outlines the results of the imaging study, which is essential for guiding further clinical management.

3. Post-Procedure

After the completion of the testicular imaging with vascular flow, the patient may be monitored briefly to ensure there are no immediate adverse reactions to the radiolabeled isotope tracer. There are typically no specific post-procedure care requirements, but patients may be advised to hydrate adequately to help flush the tracer from their system. The physician will review the images obtained during the procedure and provide a detailed report, which will be used to inform any necessary follow-up actions or treatments based on the findings.

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.
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.
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
