Administration set, with small volume filtered pneumatic nebulizer

HCPCS code

Name of the Procedure:

Administration set, with small volume filtered pneumatic nebulizer (Code: A7006)


This procedure involves using a pneumatic nebulizer with a small volume filtered administration set to deliver medication directly into the lungs via inhalation. It converts liquid medicine into a fine mist, making it easier to inhale deep into the respiratory system.


The primary purpose of this procedure is to treat respiratory conditions such as asthma, chronic obstructive pulmonary disease (COPD), cystic fibrosis, and other lung infections. By delivering medication directly to the lungs, it helps to open airways, reduce inflammation, and improve respiratory function.


This procedure is indicated for patients who experience:

  • Persistent asthma attacks despite using inhalers
  • Chronic bronchitis or COPD flare-ups
  • Cystic fibrosis complications
  • Respiratory infections requiring medication directly to the lungs
  • Respiratory distress or difficulty breathing


Patients are typically advised to:

  • Continue prescribed medications unless instructed otherwise
  • Avoid heavy meals and smoking before the procedure
  • Inform the healthcare provider of any allergies, especially to the nebulized medication
  • Perform any required lung function tests prior to the procedure

Procedure Description

  1. Setup: The healthcare professional assembles the pneumatic nebulizer and administration set.
  2. Medication Preparation: The prescribed medication is placed into the nebulizer's medication chamber.
  3. Patient Positioning: The patient is seated comfortably, often in an upright position.
  4. Nebulization: The nebulizer is activated, and the patient breathes in the medication through a mouthpiece or mask for about 5-10 minutes.
  5. Monitoring: The healthcare provider monitors the patient's breathing and response to the medication.


The procedure typically takes about 15-20 minutes, including setup, nebulization, and monitoring.


This procedure can be performed in various settings, including:

  • Hospitals
  • Outpatient clinics
  • Home healthcare settings with supervision


The procedure is usually conducted by:

  • Respiratory therapists
  • Nurses
  • Sometimes directly by the patient under healthcare provider guidance

Risks and Complications

Common risks include:

  • Throat or mouth irritation
  • Dry mouth
  • Mild headache

Rare but possible complications include:

  • Allergic reactions to medication
  • Increased heart rate or palpitations
  • Infection from improper equipment sterilization


Patients can expect:

  • Improved breathing and reduction in symptoms within minutes
  • Direct delivery of medication to the lungs, enhancing its effectiveness
  • Reduced frequency and severity of asthma or COPD attacks


Post-procedure care includes:

  • Rinsing the mouth and face if a mask was used
  • Cleaning the nebulizer according to manufacturer instructions
  • Monitoring for any delayed reactions to medication
  • Resuming normal activities as tolerated


Alternative treatments include:

  • Metered-dose inhalers (MDIs)
  • Dry powder inhalers (DPIs)
  • Oral medications (e.g., pills, syrups)
  • Injectable medications

Each alternative has its pros and cons, such as ease of use, onset time, and effectiveness, depending on the patient's specific condition and severity.

Patient Experience

During the procedure, the patient may:

  • Feel a cool mist and slight vibration from the nebulizer
  • Experience minimal to no discomfort

Post-procedure, patients might feel immediate relief in breathing, with minimal side effects. Pain management and comfort measures are rarely necessary but can include ensuring proper humidification and hydration if throat irritation occurs.
