Official Description

Venipuncture, cutdown; younger than age 1 year

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Venipuncture is a medical procedure that involves the puncturing of a vein to obtain blood samples or to administer medications. In the case of CPT® Code 36420, this procedure is specifically performed using a cutdown technique for patients who are younger than one year of age. The cutdown method is utilized when standard venipuncture techniques are not feasible due to the small size or depth of the veins in infants. This technique requires careful preparation of the site to ensure a sterile entry point. The skin is gently nicked to expose the vein, allowing for direct access. Once the vein is adequately exposed, a needle is inserted to collect the necessary blood samples or to deliver medications. It is important to note that for patients aged one year or older, a different code, CPT® Code 36425, should be used to reflect the procedural differences associated with older children and adults.

1. Indications

The venipuncture cutdown procedure, as described by CPT® Code 36420, is indicated for specific clinical situations involving infants. The following conditions may warrant the use of this procedure:

  • Access Difficulties When standard venipuncture is not successful due to the small size or depth of the veins in infants, a cutdown may be necessary to obtain vascular access.
  • Need for Blood Samples This procedure is often performed to collect blood samples for diagnostic testing when other methods are impractical.
  • Medication Administration In cases where intravenous medication needs to be administered and standard access is not achievable, a cutdown can provide the necessary access to deliver treatment.

2. Procedure

The venipuncture cutdown procedure involves several critical steps to ensure successful access to the vein. Each step is essential for the safety and effectiveness of the procedure.

  • Step 1: Site Preparation The first step involves preparing the site for the procedure. This includes cleaning the area with an antiseptic solution to minimize the risk of infection and ensuring a sterile environment for the cutdown.
  • Step 2: Skin Incision After the site is prepared, a small incision is made in the skin over the targeted vein. This incision is typically shallow and is designed to expose the vein without causing excessive trauma to the surrounding tissue.
  • Step 3: Vein Exposure Once the skin is incised, the healthcare provider carefully dissects the tissue to expose the vein. This step requires precision to avoid damaging the vein or surrounding structures.
  • Step 4: Needle Insertion With the vein exposed, a needle is inserted directly into the vein. This allows for the collection of blood samples or the administration of medications as needed.
  • Step 5: Sample Collection or Medication Delivery After successful insertion, the necessary blood samples are drawn, or medications are administered through the needle, ensuring that the procedure meets the clinical needs of the patient.

3. Post-Procedure

Following the venipuncture cutdown procedure, appropriate post-procedure care is essential to ensure the well-being of the infant. The site should be monitored for any signs of bleeding or infection. A sterile dressing may be applied to protect the incision site. Parents or caregivers should be instructed on how to care for the site and watch for any unusual symptoms, such as swelling or redness. Additionally, follow-up appointments may be necessary to assess the site and ensure proper healing.
