CPT® Code 94360

Deleted

The CPT® Code 94360 refers to the procedure for determining resistance to airflow in the lungs using either oscillatory or plethysmographic methods. This procedure is essential for assessing how easily air can flow in and out of the lungs, which is a critical factor in evaluating respiratory function. The term "resistance to airflow" indicates how much the airflow is impeded as it moves through the airways. This measurement can provide valuable insights into various pulmonary conditions. The oscillatory method involves analyzing the vibrations created by the airflow, while the plethysmographic method measures changes in lung volume during inhalation and exhalation. Both techniques are non-invasive and are used to help diagnose and monitor respiratory diseases, ensuring that healthcare providers can make informed decisions regarding patient care and treatment options.
