The Centers for Medicare & Medicaid Services is reviewing its national coverage decision regarding the diagnosis of patients with OSA requiring CPAP therapy. Current national coverage guidelines specify that only a polysomnography done in a facility-based sleep study laboratory be used to identify patients with OSA requiring CPAP (CIM 60-17). CMS has received a Request [PDF, 78KB] from Dr Terence M. Davidson, MD, of the University of California San Diego, School of Medicine to modify this decision to include the use of portable multi-channel home sleep testing devices as an alternative to facility-based polysomnography in the evaluation of OSA.
