(a) Sleep studies. Sleep studies are the continuous and simultaneous monitoring and recording of specified physiological and pathophysiological parameters during a period of sleep for six (6) or more hours. The study is used to diagnose a variety of sleep disorders and to evaluate a patient's response to therapies such as continuous positive airway pressure (CPAP). A sleep study requires physician review, interpretation, and report.
(b) Medical necessity. Sleep studies must be determined by a provider to be medically necessary and documented in the member's plan of care as medically necessary and used for medical purposes. A request by a qualified provider for sleep studies in and of itself shall not constitute medical necessity. The Oklahoma Health Care Authority (OHCA) shall serve as the final authority pertaining to all determinations of medical necessity. Refer to Oklahoma Administrative Code (OAC) 317:30-5-211.2 and 317:30-3-1(f) for policy on medical necessity.
(c) Documentation. All documentation submitted to request services must demonstrate, through adequate objective medical records, evidence sufficient to justify the member's need for the service, in accordance with OAC 317:30-3-1(f)(2). Documentation requirements include:
