Name of the Procedure:

Needle-Free Injection Device, Each
Common Name(s): Needle-Free Injector
Technical/Medical Term: Needle-Free Injection System (A4210)


A needle-free injection device administers medication or vaccines without the use of a traditional needle. It uses high-pressure technology to deliver the substance through the skin.


This procedure is designed to deliver medications and vaccines to patients without the discomfort and anxiety associated with needles. It addresses needle phobia and reduces the risk of needle-stick injuries.


  • Patients with needle phobia or anxiety

  • Children or individuals with sensitive skin
  • Diabetic patients for insulin injections


  • No fasting is typically required.
  • Inform the healthcare provider of any allergies or current medications.
  • Ensure the skin area for injection is clean and free from infection.

Tools/Equipment: Needle-free injection device (spring-loaded or gas-powered) Anesthesia/Sedation: Generally not required.


The actual injection process takes only a few seconds, with the overall procedure typically lasting around 5-10 minutes.
