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 |
