What 95012 covers

This office-based test measures nitric oxide in a patient’s exhaled breath, typically with a dedicated analyzer and a controlled breathing maneuver. Allergy and immunology, pulmonary, and other clinicians use the result as one measure of eosinophilic airway inflammation, often when evaluating asthma or monitoring response to anti-inflammatory treatment. Trained clinical staff may perform the breathing procedure under physician supervision.

Report 95012 for the FeNO measurement, not for each breath used to obtain a valid result. Documentation should identify the clinical reason for testing and include the measured result. CMS treats this as an incident-to service: it may be billed only when performed under physician supervision. The code does not describe airflow testing; spirometry or a bronchial challenge addresses different aspects of respiratory function and may be reported when separately performed.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

95012 billing questions

When is FeNO testing appropriate instead of spirometry?

Use 95012 to measure exhaled nitric oxide as an indicator of airway inflammation. Spirometry measures airflow and is used to evaluate ventilatory function.

Can clinical staff perform the test?

Yes. CMS permits billing as an incident-to service only when the test is performed under physician supervision.

Are repeated breaths billed as separate units?

No. The code represents the FeNO measurement service; the breaths used to obtain a valid measurement are not separate tests.

What documentation supports reporting 95012?

Record the reason for testing, the measured result, and the physician supervision supporting incident-to billing.

Can FeNO be reported with spirometry?

They measure different findings: FeNO measures exhaled nitric oxide, while spirometry evaluates airflow. Both may be reported when each service is performed and documented.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
