When you, the nurse or medical assistant spend time helping a patient with an inhaler demo or evaluation, keep in mind these things:

• What type of device you are using
• Documentation
• Qualifying modifiers

If you are providing separate education after the patient has received an inhalation treatment on the same day, you will be able to report 94664 twice, the second code appended with a ‘59’ modifier to indicate that the procedure was for teaching purposes.

The bottom line, documentation and medical necessity for the services performed. You are entitled to payment (about $16.00) for this service each time it is provided. The approved diagnosis would always be a respiratory code. As example: 493.01 Extrinsic asthma, with status asthmaticus or 493.22, chronic obstructive asthma.
