ProSomnus® Announces Availability of Insurance Reimbursement for Oral Appliance Therapy Devices in Germany

SAN FRANCISCO, Sept. 15, 2022 (GLOBE NEWSWIRE) — ProSomnus, a pioneer in precision medical devices for the treatment of Obstructive Sleep Apnea (OSA), today announced that the ProSomnus EVO^TM Sleep and Snore Device is now reimbursable by Germany’s public health insurance system.

The ProSomnus EVO is an alternative to legacy oral devices and CPAP machines, and can result in more effective treatment and superior patient compliance. It repositions and stabilizes the jaw during sleep, improving airflow through a patient’s pharyngeal space. The ProSomnus EVO consists of maxillary and mandibular aligner trays for orthodontic treatment that are precision-manufactured with twin-mated posts, and is digitally milled to be patient-specific. Prescribed advancements can be achieved by removing the current upper- or lower-device arch and inserting the next arch in the mandibular advancement series.

“The German reimbursement update provides an excellent opportunity to scale treatment for thousands of patients with OSA,” stated Gregory Vogel, VP International Business for ProSomnus. “ProSomnus’s precedent of providing first-class products and services in North America paves the way for growth and expansion in Europe. We are excited to continue our investment in the people and resources needed to support our clinical providers.”

“Validating reimbursement helps establish ProSomnus precision intraoral devices as an effective, patient-preferred and economically viable treatment option for healthcare providers in Germany and the estimated 26 million people in the country suffering from OSA,” said Len Liptak, Co-Founder and Chief Executive Officer of ProSomnus.
