Spirometry
A common pulmonary function test measuring how much air a patient inhales and exhales and how quickly, used to diagnose and monitor conditions like asthma and COPD. It carries specific procedure codes when performed and billed in outpatient settings.
What is spirometry?
Spirometry is a common pulmonary function test that measures how much air a patient can breathe in and out and how quickly they can do so. The patient breathes into a device that records airflow and volume, producing values clinicians use to evaluate lung function.
The test is widely used to diagnose and monitor respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD). Because it is noninvasive and relatively quick, it is a practical tool in many outpatient settings.
How is spirometry handled in outpatient billing?
When spirometry is performed and billed in an outpatient setting, it is reported using specific procedure codes that correspond to the type of test conducted. Accurate code selection ensures the service is reimbursed correctly and reflects what was actually done.
Because spirometry is a frequently performed test, getting its coding and documentation right contributes to clean claims across high volumes. Proper reporting supports both compliance and timely reimbursement for respiratory diagnostics.
