What 94669 covers
This service covers a treatment session using a powered oscillatory vest or comparable chest-wall device to loosen and mobilize airway secretions. It may be part of an airway-clearance plan for patients who have difficulty clearing secretions, including people with cystic fibrosis or bronchiectasis. Respiratory therapists commonly deliver the treatment in an outpatient pulmonary or respiratory-care setting while the patient wears the device.
Report 94669 for mechanical treatment, rather than hands-on chest percussion or vibration. The treatment record should identify the airway-clearance indication and the device-based session, and may describe the patient’s tolerance or response. The code is reported per session, not by elapsed time. CMS treats this as an incident-to service: it may be billed only when performed under physician supervision. CMS assigns no physician work RVU; its valuation reflects practice expense and malpractice.
This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

- 94668 represents subsequent hands-on chest-wall treatment. It does not describe a device-based oscillation session.
- 94640Inhalation treatment
- 94640 covers an inhalation treatment, such as delivery of an inhaled medication. It does not represent mechanical mobilization of airway secretions.
94669 billing questions
How does 94669 differ from manual chest physiotherapy?
94669 represents a mechanical oscillation treatment session. Hands-on chest percussion or vibration is represented by 94667 or 94668, depending on whether it is the initial or a subsequent service.
Is 94669 reported by time or by session?
It is reported per treatment session, not by elapsed time.
Can a respiratory therapist perform the service?
Yes. CMS permits billing as an incident-to service only when the treatment is performed under physician supervision.
Can an inhalation treatment also be reported?
A separately performed inhalation treatment, such as bronchodilator delivery, is represented by 94640. The record should distinguish that treatment from the mechanical chest-wall session.
What should the treatment record identify?
Document the airway-clearance indication and the mechanical device session. A note about the patient’s tolerance or response can further describe the service performed.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
