About 94664: Patient inhaler technique demonstration and evaluation
Report this service when a clinician demonstrates or evaluates a patient's use of an inhaler, nebulizer, or other aerosol delivery device.
This service involves teaching a patient how to use an aerosol delivery device or watching the patient use it to evaluate technique. The clinician may correct errors such as poor coordination with a metered-dose inhaler or improper handling of a nebulizer. It is commonly provided in an office or other setting where respiratory care is delivered, by a physician or appropriately supervised clinical staff.
Report the service for device-use instruction or technique evaluation, not simply because an inhaled medication was administered. Documentation should identify the device, the instruction or evaluation performed, and relevant findings about the patient's technique. CMS treats 94664 as an incident-to service: it may be billed only when performed under physician supervision.

94664 billing questions
When should 94664 be reported instead of 94640?
Use 94664 for demonstrating or evaluating the patient's technique with an aerosol delivery device. Code 94640 describes an inhalation treatment; a treatment alone does not establish that device instruction or evaluation occurred.
Can 94664 and 94640 be reported on the same date?
They may describe separate services when the patient receives an inhalation treatment and also receives distinct device-use instruction or technique evaluation. Document each service separately.
What documentation supports 94664?
Record the device involved, what instruction or technique assessment was performed, and any relevant technique problems or corrections.
Can clinical staff perform this service?
Yes, but CMS treats it as an incident-to service, so it may be billed only when performed under physician supervision.
Does administering medication by inhaler or nebulizer qualify by itself?
No. The service is demonstration or evaluation of the patient's device use; medication administration alone is not the service described by 94664.
Where these rates come from
