What 94070 covers

This test evaluates airway response to a provoking stimulus through repeated spirometric measurements. A pulmonary function laboratory may administer an inhaled agent such as methacholine, or use another stimulus such as cold air or an allergen, while recording changes in airflow. Pulmonologists and allergists commonly order it when asthma or airway hyperreactivity is suspected but routine spirometry has not established the diagnosis. Testing is typically performed by trained pulmonary function staff, with a qualified professional interpreting the results.

Report 94070 for the provocation evaluation and its serial spirometry, rather than for routine spirometry alone or a bronchodilator response test. Documentation should identify the stimulus, show the baseline and subsequent measurements, and support the interpretation of the airway response. The repeated spirometric determinations performed as part of the challenge are included in this service. CMS recognizes professional and technical components: report modifier 26 for interpretation only, modifier TC for equipment and staff only, or no component modifier for the global service.
