Can I report code 94664 for patients who use their nebulizers routinely at home as part of their treatment plans?


Code 94664 describes “demonstration and/or evaluation of patient utilization of an aerosol generator, nebulizer, metered dose inhaler or IPPB device,” but this code should not be billed for patients who routinely use their device to provide treatments at home unless there are unusual circumstances.

The documentation in the patient’s medical record should give the rationale for providing the patient education related to bronchodilator administration and should include comments about the patient’s ability to correctly use the delivery device.
