Official Description

Angioscopy (noncoronary vessels or grafts) during therapeutic intervention (List separately in addition to code for primary procedure)

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

An angioscopy of non-coronary vessels or grafts is a specialized medical procedure that involves the use of a fiberoptic imaging system to visualize the interior of blood vessels. This procedure is typically performed during a therapeutic intervention, which means it is conducted in conjunction with another primary procedure that is separately reportable. The angioscopy technique utilizes a combination of illumination fibers and imaging fibers, along with a video camera and monitor, to capture detailed images of the blood vessel's interior. This allows healthcare professionals to assess the condition of the vessel or graft in real-time. The process begins with the cleansing of the skin over the access vessel, followed by puncturing the vessel to insert a sheath. A guidewire is then advanced to the targeted non-coronary vessel or graft, and the angioscopy catheter is carefully maneuvered into position. An occlusion balloon is inflated to facilitate the examination, and the vessel is flushed with lactated Ringer's solution to enhance visibility. The imaging bundle is advanced to the area of interest, where images are captured and displayed on a monitor for the physician to review and interpret. A written report is subsequently generated to document the findings of the angioscopy.

1. Indications

The angioscopy procedure is indicated for various clinical scenarios involving non-coronary vessels or grafts. The following conditions may warrant the performance of angioscopy:

  • Assessment of Vascular Conditions Angioscopy is utilized to evaluate the status of blood vessels that may be affected by conditions such as stenosis, occlusion, or other abnormalities.
  • Evaluation of Grafts This procedure is indicated for examining the patency and integrity of vascular grafts, ensuring they are functioning properly and free from complications.
  • Therapeutic Intervention Angioscopy is performed during therapeutic interventions to provide real-time visualization, aiding in the decision-making process for further treatment options.

2. Procedure

The angioscopy procedure involves several critical steps to ensure effective visualization of the non-coronary vessels or grafts. Each step is essential for the successful execution of the procedure:

  • Step 1: Preparation The procedure begins with the preparation of the patient and the access site. The skin over the access vessel is thoroughly cleansed to minimize the risk of infection. This step is crucial for maintaining a sterile environment during the procedure.
  • Step 2: Vessel Puncture After cleansing, the physician punctures the vessel to gain access. This is typically done using a needle, and care is taken to ensure that the puncture is performed accurately to avoid complications.
  • Step 3: Sheath Insertion A sheath is then placed into the punctured vessel. The sheath serves as a conduit for the subsequent instruments and helps maintain access to the vessel throughout the procedure.
  • Step 4: Guidewire Advancement Following sheath insertion, a guidewire is advanced through the sheath to the targeted non-coronary vessel or graft. The guidewire is essential for guiding the angioscopy catheter into the correct position.
  • Step 5: Catheter Advancement The angioscopy catheter is advanced over the guidewire to a point just proximal to the area that will be imaged. This positioning is critical for obtaining clear images of the vessel.
  • Step 6: Balloon Inflation An occlusion balloon on the catheter is inflated to temporarily block blood flow in the vessel. This step enhances the visibility of the interior structures during imaging.
  • Step 7: Vessel Flushing The vessel is then flushed with lactated Ringer's solution. This flushing helps clear any debris and improves the clarity of the images captured during the procedure.
  • Step 8: Imaging The imaging bundle is advanced over the guidewire to the region of interest. Images of the interior of the blood vessel are obtained and displayed on a monitor for real-time assessment.
  • Step 9: Review and Reporting The physician reviews and interprets the images displayed on the monitor. A written report is generated to document the findings and any necessary recommendations for further treatment.

3. Post-Procedure

After the angioscopy procedure, the patient may require monitoring for any potential complications related to the access site or the procedure itself. The physician will assess the patient's condition and provide instructions for post-procedure care, which may include managing any discomfort and monitoring for signs of infection or bleeding. The written report generated during the procedure will be used to guide any further interventions or follow-up care that may be necessary based on the findings observed during the angioscopy.

58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
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.
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
