CPT® Code 94664

Demonstration and/or evaluation of patient utilization of an aerosol generator, nebulizer, metered dose inhaler or IPPB device

The CPT® Code 94664 pertains to the demonstration and/or evaluation of a patient's or caregiver's utilization of various aerosol delivery devices, including aerosol generators, nebulizers, metered dose inhalers, or intermittent positive pressure breathing (IPPB) devices. This procedure is essential as the effectiveness of inhaled medications significantly relies on the proficiency of the patient or caregiver in operating the prescribed device. The selection of the delivery device is determined by the specific type of medication being administered and the patient's or caregiver's ability to effectively master the use of that device. Typically, a respiratory therapist conducts the demonstration, providing detailed explanations regarding the proper usage of the device and the medication it delivers to ensure maximum therapeutic effectiveness. During the session, the patient or caregiver is observed while using the device, allowing the respiratory therapist to offer assistance and clarification as needed. It is important to note that achieving correct usage may necessitate multiple demonstrations and training sessions. Furthermore, this code can be reported once per day for the demonstration and/or evaluation of the correct use of the device by the patient or caregiver.
