It has been more than 15 years since the U.S. Food and Drug Administration (FDA) first approved implant therapy as an alternative to continuous positive air pressure (CPAP) machines for the treatment of sleep apnea. Over the past decade and a half, this implant therapy, or implantable treatment, for sleep apnea, has become widely used by dentists across the country. As the prevalence of sleep apnea implant therapy has increased, so has insurance companies’ scrutiny of dentists’ billings for this relatively new service.
