Official Description

Injection procedure during cardiac catheterization including imaging supervision, interpretation, and report; for nonselective pulmonary arterial angiography (List separately in addition to code for primary procedure)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 93568 refers to an injection procedure performed during cardiac catheterization specifically for nonselective pulmonary arterial angiography. This procedure is typically conducted in conjunction with a primary right heart catheterization, which can be necessary for diagnosing various congenital or acquired heart conditions in both adults and children. The primary aim of this procedure is to visualize the main pulmonary artery by injecting contrast media, allowing for a detailed assessment of the artery's structure and function. This includes evaluating for potential issues such as valve regurgitation, abnormal branching of blood vessels, or other vascular abnormalities. The procedure involves positioning a diagnostic catheter in the main pulmonary artery, which is then connected to a power injector for the administration of contrast media. This process is crucial for obtaining clear images that can help in diagnosing and planning further treatment for patients with heart conditions. It is important to note that while nonselective pulmonary arterial angiography is applicable to a broader patient population, selective pulmonary arterial angiography is more commonly performed in pediatric patients, particularly those with congenital heart defects. The careful monitoring of the patient's vital signs and potential complications during and after the procedure is also a critical aspect of the overall process.

1. Indications

The injection procedure for nonselective pulmonary arterial angiography (CPT® Code 93568) is indicated for the evaluation of various conditions affecting the pulmonary artery. The following are the explicitly provided indications for this procedure:

  • Congenital Heart Conditions - This procedure is often performed in pediatric patients to assess congenital heart defects that may affect pulmonary blood flow.
  • Acquired Heart Conditions - Adults may undergo this procedure to evaluate acquired conditions that impact the pulmonary artery and its branches.
  • Assessment of Valve Regurgitation - The procedure helps in determining the presence of valve regurgitation, which can lead to significant cardiovascular complications.
  • Evaluation of Vessel Abnormalities - It is used to identify any abnormalities in the structure of the pulmonary artery and its branches.

2. Procedure

The procedure for nonselective pulmonary arterial angiography involves several critical steps, which are detailed as follows:

  • Step 1: Catheter Positioning - A diagnostic catheter is carefully positioned in the main pulmonary artery. This positioning is crucial as it allows for the effective delivery of contrast media to visualize the pulmonary artery.
  • Step 2: Connection to Power Injector - Once the catheter is in place, it is connected to a power injector. This device is essential for administering the contrast media at the appropriate pressure and volume, ensuring optimal imaging results.
  • Step 3: Contrast Media Injection - Contrast media is injected through the catheter to opacify the main pulmonary artery. This step is vital for visualizing the artery and assessing its condition.
  • Step 4: Imaging and Evaluation - The images obtained from the contrast injection are processed and reviewed by the physician. This evaluation focuses on identifying any abnormalities, such as valve regurgitation or branching blood flow issues.
  • Step 5: Monitoring - Throughout the procedure, the patient's arterial pressure, heart rhythm, and oxygen levels are continuously monitored to ensure safety and detect any immediate complications.
  • Step 6: Post-Procedure Monitoring - After the procedure, the patient is monitored for any potential allergic reactions, arrhythmias, kidney damage, or other complications that may arise from the contrast media or the procedure itself.

3. Post-Procedure

Following the nonselective pulmonary arterial angiography, patients are typically monitored for any adverse reactions to the contrast media, which may include allergic responses or kidney function impairment. Continuous observation of the patient's heart rhythm and vital signs is essential during the recovery phase. Additionally, any complications such as arrhythmias or other cardiovascular issues must be promptly addressed. The physician will provide a written interpretation of the findings from the angiography, which will guide further management and treatment decisions based on the results obtained during the procedure.

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.
