HCPCS Code E0482: Cough Stimulating Device, Alternating Positive and Negative Airway Pressure

It can usually take just 20 minutes, unless specified by the healthcare provider based on the patient's condition and needs.

It's normal for patients to feel a bit of discomfort or irritation because of the mask piece. They might even feel a little dizzy, too. Rare complications include barotrauma and the possibility of any pre-existing respiratory problems being exacerbated for a bit.

Some patients will feel it immediately after using the device. Some might feel the benefits a few hours later.
