What 94660 covers

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.

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.

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 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.
