Sleep apnea is a serious sleep disorder that occurs when a person’s breathing is repeatedly interrupted during sleep. The involuntary pause in breathing can result either from a blocked airway or a signaling problem in the brain. Treatment for this condition involves using certain breathing devices such as oral appliances (OAT); positive airway pressure (PAP) machine and other airway pressure devices that can help open up a blocked airway. Dental offices must make sure whether the patients are eligible for various treatments, in order to get reimbursed. To become eligible to bill Medicare for OAT, dentists must apply to become a Medicare Durable Medical Equipment (DME) supplier. One of the main challenges faced by DME suppliers is insurance eligibility verification, which can be handled by experienced medical billing firms. With about 18 million Americans suffering from sleep apnea, the demand for OAT devices is also on the rise. Here are some of the frequently asked questions and answers about medical insurance verifications and reimbursements for oral appliances.
