Respiratory Question for the Week of March 29, 2021

Respiratory Compliance Question of the Week

Question:

We are getting denials when reporting 94640, can you please clarify what the code accounts for?

Answer:

The description of code 94640 was revised in 2016 to clarify that this is a bundled code representing both diagnostic and therapeutic services. Code 94640 includes different modes of treatment including aerosol generator, nebulizer, a metered-dose inhaler (MDI), or intermittent positive pressure breathing (IPPB) device. This code is appropriate when documentation indicates the treatment is administered to a patient with an acute airway obstruction. It should not be reported for a routine nebulizer or MDI treatments for patients with unrelated conditions. In addition, this code is to be reported for the induction of sputum for diagnostic purposes.

94640 Pressurized or nonpressurized inhalation treatment for acute airway obstruction for therapeutic purposes and/or for diagnostic purposes such as sputum induction with an aerosol generator, nebulizer, metered dose inhaler or intermittent positive pressure breathing (IPPB) device
