Sleep Testing

Once a patient has been evaluated for symptoms associated with sleep apnea, testing is ordered to identify severity and determine treatment.

There are several types of sleep tests, but coverage is based on meeting the criteria for Type I (inpatient facility based) or Type II-IV and Other (home-based sleep tests). All sleep tests require interpretation by a practitioner who holds specific credentials. (See LCD33718).

Type of sleep test and requirements for each are as follows:

Type I Device - Facility based

TIP: Even though the patient may be staying the night in an ambulatory care center, freestanding clinic, or even the hospital, the sleep study is NOT considered an inpatient service. 

Home Sleep Test (Types II-IV, and Other Devices)

Special Instructions on HST Devices: Prior to the test, the patient must be instructed on how to properly apply a portable sleep monitoring device (provided by the entity conducting the HST and NOT the DME supplier) either face-to-face or via video or telephonic instruction with 24-hour access for inquiries and troubleshooting.
