Effective Date: N/A Medicine - Pulmonary Procedures Feed
Airway resistance by impulse oscillometry.
Modifiers 26 (Professional Component) and TC (Technical Component) may be applicable.
The testing provider sets up the testing instruments. The patient breathes normally through a pneumotachograph, which records airflow. The device uses sound waves and airflow to calculate airway resistance. The provider interprets the results.
In simple words: This test measures how easily air flows through your lungs using sound waves. It helps doctors understand if there's any blockage in your airways.
This code represents a pulmonary function test that measures airway resistance using impulse oscillometry. It assesses the level of obstruction to airflow noninvasively by transmitting pressure waves through the airways.
Example 1: A patient with asthma undergoes impulse oscillometry to assess airway resistance before and after bronchodilator administration., A patient with suspected COPD undergoes impulse oscillometry to evaluate the degree of airway obstruction., A patient with cystic fibrosis undergoes impulse oscillometry to monitor lung function and treatment response.
Documentation should include the test results (numerical values and percentages of predicted values), interpretation, and any relevant clinical findings.
