The Board remands the claim for service connection for upper airway resistance syndrome (UARS), to include obstructive sleep apnea (OSA), as a pre-decisional duty to assist error occurred by not conducting all necessary medical testing, specifically a sleep study.
The deciding factor: The M21-1 provisions indicate that UARS does not meet the criteria of sleep-disordered breathing and is not considered a ratable disability for compensation purposes. However, a remand is required as the Veteran has not undergone a sleep study since 2019 to determine whether his condition may have progressed towards OSA.
