About 94660: CPAP initiation and management
Report CPAP initiation and management when a clinician starts or manages continuous positive airway pressure therapy, commonly for obstructive sleep apnea.
This service covers a clinician’s work to begin or manage continuous positive airway pressure (CPAP) therapy. It is commonly provided by pulmonary or sleep-medicine clinicians for patients with obstructive sleep apnea, in an office or facility setting. The service concerns the patient’s CPAP treatment, such as getting therapy started and addressing its use; it is distinct from supplying or renting the CPAP equipment.
Report 94660 when the documented encounter includes CPAP initiation or management, not merely a discussion of a planned treatment or a note that the patient already uses CPAP. Documentation should identify the clinical reason for therapy and the work performed, such as device or interface setup, changes made, patient instruction, or response when applicable. CMS values practice expense differently for office and facility settings, so the place of service affects the payment valuation. The code has no add-on designation in the supplied CMS facts.

94660 billing questions
How is 94660 different from a CPAP titration sleep study?
94660 describes CPAP initiation or management. An attended sleep study that records sleep and titrates pressure is a separate service, such as 95811.
Does 94660 pay for the CPAP machine or mask?
No. It represents the clinical service of initiating or managing therapy, not the purchase or rental of equipment.
Can 94664 be used for CPAP mask instruction?
94664 concerns demonstration or evaluation of aerosol-device use, such as an inhaler or nebulizer. CPAP initiation and management belong under 94660 when that is the service performed.
What should the record show to support 94660?
Document the reason for CPAP therapy and the initiation or management work performed. Include relevant setup or interface changes, instruction, and the patient’s response when these occurred.
Is 94660 reported for a diagnostic sleep study?
No. A diagnostic polysomnography service is distinct from CPAP initiation and management; select the sleep-study code that matches the study 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 indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
