Small volume nonfiltered pneumatic nebulizer, disposable

HCPCS code

Name of the Procedure:

Small Volume Nonfiltered Pneumatic Nebulizer, Disposable (HCPCS Code: A7004)


A small volume nonfiltered pneumatic nebulizer is a device used to administer medication in the form of a mist inhaled into the lungs. It is typically disposable and used for a single treatment or for a limited period.


This nebulizer is used to treat respiratory conditions such as asthma, chronic obstructive pulmonary disease (COPD), and other lung diseases. The primary goal is to deliver medication directly to the lungs to relieve symptoms like shortness of breath, wheezing, and coughing.


  • Chronic respiratory conditions: asthma, COPD
  • Acute respiratory infections: bronchitis
  • Spasticity in airway passages
  • Patients who have difficulty using inhalers


  • No specific dietary restrictions or fasting required.
  • The patient should have a recent medical history and physical examination focused on respiratory health.
  • Any current medications should be reviewed with the healthcare provider.

Procedure Description

  1. Setup: The nebulizer device is assembled according to the manufacturer's instructions.
  2. Medication Loading: The prescribed dose of medication is placed in the nebulizer cup.
  3. Connection: The nebulizer is connected to an air compressor via tubing.
  4. Operation: When turned on, the compressor forces air through the liquid medication, turning it into a fine mist.
  5. Inhalation: The patient breathes in the mist through a mouthpiece or mask until the medication is fully administered (usually 5-10 minutes).

No anesthesia or sedation is required.


The entire process typically takes around 10-15 minutes.


This procedure can be performed in a variety of settings, including hospitals, outpatient clinics, or at home.


  • Respiratory therapists
  • Nurses
  • Physicians (for prescription and oversight)

Risks and Complications

  • Minor side effects such as throat irritation, dry mouth, or a bad taste.
  • Rarely, a patient may experience an allergic reaction to the medication or the plastic components of the nebulizer.
  • Overuse can lead to medication overdosage.


  • Rapid relief of respiratory symptoms.
  • Direct delivery of medication to the lungs, leading to quicker onset of action.
  • Enhanced medication absorption compared to oral intake.


  • No recovery time is generally required.
  • Post-procedure, the patient may be advised on breath exercises or techniques to maximize inhalation efficiency.
  • Regular cleaning or disposal of the nebulizer to avoid infection.


  • Metered-dose inhalers (MDIs)
  • Dry powder inhalers
  • Systemic medications (oral or injectable)

Each alternative has its own pros and cons, including ease of use, speed of relief, and side-effect profiles.

Patient Experience

During the procedure, the patient may feel a cool mist and hear the sound of the air compressor. They might experience immediate relief, but comfort varies depending on the medication used. Pain is not typically associated with this procedure. Proper usage instructions and routine cleaning can enhance comfort and efficacy.
