HCPCS code

Name of the Procedure:

Administration set, with small volume nonfiltered pneumatic nebulizer, disposable
Common Names: Nebulizer therapy, breathing treatment
Technical/Medical Terms: A7003 pneumatic nebulizer administration


Nebulizer therapy involves using a device to convert liquid medication into a fine mist for inhalation into the lungs. This helps deliver medication directly to the respiratory system, offering relief from respiratory conditions.


Nebulizer therapy is primarily used to treat respiratory conditions such as asthma, chronic obstructive pulmonary disease (COPD), and other bronchial disorders. The goal is to open airways, reduce inflammation, and ease breathing.


  • Frequent wheezing or breathlessness
  • Asthma
  • Chronic obstructive pulmonary disease (COPD)
  • Bronchitis
  • Cystic fibrosis
  • Severe allergies affecting breathing


  • No specific dietary restrictions usually required.
  • Patients should read medication labels and instructions.
  • Patients may need to perform spirometry or other pulmonary function tests beforehand.

Procedure Description:

  1. Setup: Connect the disposable nebulizer to the air compressor.
  2. Medication: Measure and place the prescribed medication into the nebulizer cup.
  3. Assembly: Attach the mouthpiece or mask to the nebulizer cup.
  4. Inhalation: Place the mouthpiece in the mouth or position the mask, and turn on the compressor.
  5. Administration: Breathe normally through the mouth while the nebulizer works (typically 5–10 minutes).
  6. Completion: Once all the medication has been nebulized, turn off the compressor and disassemble the parts for cleaning or disposal.
