HCPCS code

Name of the Procedure:

Needle, sterile, any size, each (A4215)
Common Names: Sterile needle, Hypodermic needle
Technical/Machine: Hypodermic needle (sterile)


A sterile needle is a single-use medical tool used for a variety of purposes, such as injecting medications, drawing blood, or administering fluids. It comes in various sizes depending on its intended use.


Sterile needles are essential for ensuring that injections or blood draws are performed in a hygienic manner, reducing the risk of infection. The goals include accurate delivery of medications or obtaining uncontaminated blood samples.


Sterile needles are indicated for:

  • Administering vaccinations
  • Injecting medications (e.g., insulin)
  • Drawing blood for diagnostic tests
  • Administering intravenous fluids


  • Clean the injection site with an alcohol swab.
  • Confirm the correct needle size for the intended purpose.
  • Ensure all materials are sterile and properly packaged.

Procedure Description

  1. Preparation: The healthcare provider gathers the necessary sterile needle and other related materials (e.g., medication vial).
  2. Cleaning and Sanitizing: The injection or draw site is cleaned with an antiseptic wipe.
  3. Injection/Draw: The needle is carefully inserted into the skin or vein, following proper technique to minimize discomfort.
  4. Completion: After administering the medication or drawing blood, the needle is safely disposed of in a sharps container.


The procedure typically takes a few minutes, depending on the specific task involved (e.g., drawing blood vs. administering a vaccine).


This procedure is commonly performed in various settings, including:

  • Hospitals
  • Outpatient clinics
