Summary
BCBS Mississippi updated their medical policy declaring that measurement of exhaled nitric oxide (FeNO) and exhaled breath condensate (EBC) are investigational for diagnosis and management of asthma, eosinophilic asthma, and other respiratory disorders including COPD and chronic cough. This means these services are not covered and claims will be denied.
Action Required
Immediately: Billing team must verify that no claims are being submitted for exhaled nitric oxide or exhaled breath condensate testing procedures. If currently billing for these services, stop billing immediately as BCBS Mississippi considers them investigational and will deny coverage. Update encounter forms to alert providers that these tests are not covered for respiratory conditions.
