What 94012 covers
This service measures airflow in a patient age two years or younger before and after a bronchodilator is given. It is typically performed in a pediatric pulmonary function laboratory or specialty setting by trained pulmonary testing staff, with a physician interpreting the results. The measurements help assess airflow limitation and whether it changes after medication; the patient's young age makes this a distinct service from routine spirometry used for older patients.
Select this code when the documented service includes both the baseline spirometry and post-bronchodilator measurements. The record should support the patient's age, the medication administration, and the testing performed before and after it. Do not separately report the baseline-only infant spirometry code for the same pre- and post-medication testing service. CMS assigns physician-work, practice-expense, and malpractice relative values to this service.

94012 billing questions
When should 94012 be chosen instead of 94011?
Use 94012 when spirometry is performed before and after a bronchodilator for a patient age two years or younger. Use 94011 for the applicable age group when the service is spirometry without bronchodilator testing.
Can baseline spirometry be reported separately with 94012?
The baseline measurements are part of the pre- and post-bronchodilator service represented by 94012. Do not separately report 94011 for that same testing.
What documentation supports reporting 94012?
Document the patient's age, the spirometry measurements, the bronchodilator administered, and measurements obtained after administration. The record should show that both phases of testing were performed.
Is 94012 the right code for an older child receiving bronchodilator spirometry?
No. This code is limited to patients age two years or younger; 94060 is the related pre- and post-bronchodilator spirometry code commonly considered for older patients.
Does 94012 describe an infant lung-volume measurement?
No. It describes spirometry with bronchodilator testing. Code 94013 is the related infant service for lung-volume measurement.
