Spirometry (Basic Lung Function Test)

Illinois rates for HCPCS 94010

This is a basic breathing test where the patient blows air forcefully into a mouthpiece connected to a machine that measures how much air the lungs can hold and how quickly it can be exhaled. The results, shown as a graph and numbers, help diagnose and monitor conditions like asthma or COPD, a long-term lung disease that narrows the airways. It's the standard, entry-level pulmonary function test, without the added gas-dilution or diffusion measurements included in more extensive lung testing.
