Official Description

Injection procedure during cardiac catheterization including imaging supervision, interpretation, and report; for selective left ventricular or left atrial angiography (List separately in addition to code for primary procedure)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 93565 refers to an injection procedure performed during cardiac catheterization, specifically for selective left ventricular or left atrial angiography. This procedure is essential for visualizing the structures and function of the left side of the heart. During this process, a catheter is carefully positioned within the left heart chambers, allowing for the injection of contrast media. This contrast agent enhances the visibility of the left ventricle and/or left atrium on imaging studies, enabling the physician to obtain detailed angiograms. These angiograms are critical for diagnosing various cardiac conditions, as they provide a clear view of blood flow and any potential abnormalities within these heart chambers. Following the procedure, the physician reviews the angiograms and generates a written report that interprets the findings, which is crucial for further clinical decision-making. It is important to note that CPT® Code 93565 is reported separately in addition to the primary procedure code for cardiac catheterization, ensuring that the injection and imaging components are accurately captured for billing and documentation purposes.

1. Indications

The injection procedure represented by CPT® Code 93565 is indicated for specific clinical scenarios where detailed visualization of the left ventricular or left atrial structures is necessary. This may include, but is not limited to, the following conditions:

  • Assessment of Cardiac Function: To evaluate the pumping ability of the left ventricle and assess for any dysfunction.
  • Investigation of Symptoms: In patients presenting with symptoms such as chest pain, shortness of breath, or unexplained fatigue, where left heart pathology is suspected.
  • Preoperative Evaluation: To provide critical information prior to cardiac surgery or interventions, ensuring that the surgical team has a comprehensive understanding of the cardiac anatomy and function.
  • Diagnosis of Structural Abnormalities: To identify any congenital or acquired abnormalities affecting the left heart chambers, such as valvular heart disease or left ventricular hypertrophy.

2. Procedure

The procedure associated with CPT® Code 93565 involves several critical steps to ensure accurate imaging and assessment of the left heart. The following outlines the procedural steps:

  • Step 1: Catheter Placement The physician begins by inserting a catheter into a suitable access point, typically the femoral artery, and carefully navigates it through the vascular system to reach the left side of the heart. This step is crucial as proper positioning of the catheter is necessary for effective contrast injection.
  • Step 2: Contrast Injection Once the catheter is correctly positioned within the left ventricle or left atrium, a contrast agent is injected through the catheter. This contrast media is essential for enhancing the visibility of the heart structures during imaging.
  • Step 3: Imaging Acquisition Following the injection of the contrast, imaging studies, such as fluoroscopy or angiography, are performed to visualize the left heart chambers. The imaging captures the flow of the contrast agent, allowing for the assessment of blood flow and any potential abnormalities.
  • Step 4: Interpretation and Reporting After the imaging is completed, the physician reviews the angiograms obtained from the procedure. A detailed written report is generated, interpreting the findings and providing insights into the patient's cardiac condition. This report is vital for guiding further management and treatment decisions.

3. Post-Procedure

Post-procedure care following the injection procedure for CPT® Code 93565 typically involves monitoring the patient for any immediate complications related to the catheterization and contrast injection. Patients may be observed for signs of bleeding at the access site, allergic reactions to the contrast media, or any cardiovascular changes. Depending on the patient's condition and the findings from the procedure, further follow-up may be necessary, including additional imaging or interventions. The physician will provide specific instructions regarding activity restrictions, medication management, and follow-up appointments to ensure optimal recovery and ongoing assessment of the patient's cardiac health.

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.
82 Assistant surgeon (when qualified resident surgeon not available): the unavailability of a qualified resident surgeon is a prerequisite for use of modifier 82 appended to the usual procedure code number(s).
