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

What 94013 covers

This service measures lung volumes using a spirometry technique in children through age 2. It is generally performed in a specialized pediatric pulmonary function laboratory by trained pulmonary function staff, such as a respiratory therapist, with physician oversight. The results help characterize pulmonary function when standard testing requiring active cooperation is not suitable for the child’s age.

Select the code when the documented service measures lung volumes, rather than only expiratory airflow or bronchodilator response. The record should support the child’s age, the spirometry technique, and the lung-volume measurements obtained. The Medicare Physician Fee Schedule represents payment through work, practice-expense, and malpractice RVUs; the practice-expense RVU listed for this code is the same in office and facility settings.
