Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

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.
