Cisternal or lateral cervical (C1-C2) puncture; without injection (separate procedure)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

A cisternal or lateral cervical (C1-C2) puncture is a medical procedure that involves the insertion of a spinal needle into the cisternal or lateral cervical region of the spine, specifically at the C1-C2 vertebral level. This procedure is performed to access the cerebrospinal fluid (CSF) for diagnostic or therapeutic purposes. The puncture can be done without the injection of any substances, which is the focus of CPT® Code 61050. During the procedure, the needle is carefully placed below the occipital bone at the back of the skull, or alternatively, the subarachnoid space can be accessed from a lateral approach. The needle is stabilized by the surrounding muscles in the neck, ensuring accurate placement. Once the needle is inserted, the stylet—a thin rod that maintains the needle's patency—is removed, allowing for the drainage of cerebrospinal fluid and potentially blood. After the desired amount of fluid is collected, the stylet is reinserted to close the needle, and a dressing is applied to the puncture site. It is important to note that if the procedure involves the injection of medication or other substances, such as contrast media or dye, CPT® Code 61055 should be used instead. This distinction is crucial for accurate coding and billing purposes.

1. Indications

The cisternal or lateral cervical (C1-C2) puncture is indicated for various clinical scenarios where access to cerebrospinal fluid is necessary. The following conditions may warrant this procedure:

  • Diagnostic Evaluation: This procedure is often performed to obtain cerebrospinal fluid for diagnostic testing, which can help identify infections, inflammatory conditions, or other neurological disorders.
  • Therapeutic Intervention: In some cases, the procedure may be indicated for therapeutic purposes, such as relieving increased intracranial pressure or administering medications directly into the cerebrospinal fluid.

2. Procedure

The procedure for a cisternal or lateral cervical (C1-C2) puncture involves several key steps that ensure proper access to the cerebrospinal fluid. The following procedural steps are outlined:

  • Step 1: The patient is positioned appropriately, typically in a sitting or lateral decubitus position, to facilitate access to the cervical region. Proper positioning is crucial for the success of the puncture.
  • Step 2: The skin over the puncture site is cleaned and sterilized to minimize the risk of infection. A local anesthetic may be administered to reduce discomfort during the procedure.
  • Step 3: A spinal needle is carefully inserted below the occipital bone at the back of the skull or laterally at the C1-C2 level. The needle is advanced slowly to reach the subarachnoid space, where cerebrospinal fluid is located.
  • Step 4: Once the needle is in the correct position, the stylet is removed. This allows cerebrospinal fluid to flow through the needle. The physician may also observe for any blood return, which could indicate a vascular puncture.
  • Step 5: After the desired amount of cerebrospinal fluid is collected, the stylet is reinserted into the needle to prevent any leakage and to maintain the integrity of the puncture site.
  • Step 6: A sterile dressing is applied to the puncture site to protect it from contamination and to promote healing.

3. Post-Procedure

After the cisternal or lateral cervical (C1-C2) puncture, the patient is typically monitored for any immediate complications, such as headache, bleeding, or signs of infection. It is important to advise the patient to remain hydrated and to rest following the procedure. Any specific post-procedure instructions, such as avoiding strenuous activities or monitoring for symptoms like severe headache or neurological changes, should be provided. Follow-up appointments may be necessary to discuss the results of the cerebrospinal fluid analysis and to assess the patient's recovery.
