Official Description

Introduction of needle or intracatheter, upper or lower extremity artery

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 36140 involves the introduction of a needle or an intracatheter into an artery located in either the upper or lower extremities. This process is essential for various medical interventions, including diagnostic and therapeutic procedures. The target arteries for this procedure often include the brachial artery in the arm or the radial artery, which is commonly accessed for various vascular procedures. To successfully perform this procedure, the healthcare provider typically begins by locating the artery through palpation, which involves feeling the pulse of the artery with their fingers. Once located, the artery is stabilized using the index and middle fingers to ensure accurate placement of the needle or intracatheter. The access site is then visualized to enhance precision during the insertion. The needle or intracatheter is carefully introduced through the skin and advanced toward the artery until the tip makes contact with the arterial wall, at which point the artery is punctured. Depending on the clinical requirements, the needle may remain in place within the artery, or an intracatheter may be further advanced into the arterial lumen. This access allows for subsequent injections, which may include medications or radiopaque contrast agents, facilitating further diagnostic imaging or treatment as necessary.

1. Indications

The procedure associated with CPT® Code 36140 is indicated for various clinical scenarios where access to an upper or lower extremity artery is required. The following conditions may warrant this procedure:

  • Diagnostic Imaging: Accessing the artery for the purpose of performing angiography or other imaging studies to visualize vascular structures.
  • Therapeutic Interventions: Facilitating the administration of medications directly into the arterial circulation for treatment purposes.
  • Catheter Placement: Insertion of an intracatheter for further diagnostic or therapeutic procedures, such as blood sampling or infusion therapies.

2. Procedure

The procedure for CPT® Code 36140 involves several critical steps to ensure successful access to the artery. The following procedural steps are outlined:

  • Step 1: Palpation and Stabilization The healthcare provider begins by palpating the target artery, such as the brachial or radial artery, to locate it accurately. Once identified, the artery is stabilized between the index and middle fingers to provide a secure point of access.
  • Step 2: Visualization of Access Area The access area over the target artery is visualized to enhance the accuracy of the needle or intracatheter insertion. This may involve adjusting the patient's position or using appropriate lighting to ensure clear visibility.
  • Step 3: Introduction of Needle or Intracatheter A sterile needle or intracatheter is then introduced through the skin at the access site. The provider carefully advances the needle toward the artery until the tip makes contact with the arterial wall.
  • Step 4: Puncturing the Artery Once the needle tip touches the arterial wall, the provider punctures the artery to gain access to the arterial lumen. This step requires precision to minimize complications.
  • Step 5: Advancement of Intracatheter Depending on the clinical need, the needle may be left in place, or an intracatheter may be advanced through the artery for further procedures. This allows for the administration of medications or radiopaque contrast as needed.

3. Post-Procedure

After the completion of the procedure, appropriate post-procedure care is essential to ensure patient safety and monitor for any complications. The access site should be observed for signs of bleeding or hematoma formation. The patient may be instructed to keep the site clean and dry, and to report any unusual symptoms such as increased pain, swelling, or discoloration. Follow-up imaging or assessments may be required to evaluate the success of the procedure and the condition of the artery accessed. Additionally, documentation of the procedure, including the details of the access site and any interventions performed, is crucial for compliance and billing purposes.

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.
51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
