CPT Code 94010 | Spirometry (Testing The Function Of Lungs)

CPT code 94010 is used to report spirometry, a test that measures the function of the lungs by measuring the flow and volume of air during inhalation and exhalation. It evaluates respiratory disorders such as COPD, asthma, and pulmonary fibrosis.

What Is CPT Code 94010?

CPT 94010 is used to report spirometry, a test measuring how well the lungs function.

The patient blows into a mouthpiece for 5 to 6 seconds until their lungs feel empty, and the test may be repeated multiple times.

The device measures the flow and volume of air during inhalation and exhalation, and a physician interprets the results.

Spirometry, also known as a pulmonary function test (PFT), is used to evaluate respiratory disorders such as COPD, asthma, and pulmonary fibrosis.

Description

The CPT book describes CPT code 94010 as: “Spirometry, including graphic record, total and timed vital capacity, expiratory flow rate measurement(s), with or without maximal voluntary ventilation.”

Procedure

The patient is asked to stand or sit up straight during this test. First, the patient breathes in and then blows hard into the spirometer’s mouthpiece for 5 to 6 seconds until he feels his lungs empty.

The technician may repeat this test several times for the best result. Later, the result is interpreted by the physician.

The device measures the flow and volume of air during inhalation and exhalation. The result is represented in a graphic format where the X axis represents the air volume, and the Y axis represents the airflow rate.

Spirometry, also known as a pulmonary function test (PFT), measures the functionality of the lungs. Respiratory disorders such as chronic obstructive pulmonary disease (COPD), asthma, and pulmonary fibrosis can be evaluated via spirometry.

How To Use CPT 94010

It is important to note that CPT 94010 should not be used in conjunction with CPT 94150, CPT 94200, CPT 94375, or CPT 94728.

Report CPT 94011, CPT 94012, and CPT 94013 for pulmonary function testing on infants and children; you should use

For patient-initiated spirometry over 30 days, you should use CPT 94014, CPT 94015, and CPT 94016.

Use CPT code 94150 for the viral capacity test as a separate procedure.

Report CPT code 94200 for a test of maximum breathing capacity or maximal voluntary ventilation.
