Sleep Apnea Treatment

My navy husband and I are scheduled to move (PCS) to London, England. I have a few health issues like high blood pressure, but they’re well managed and under control. However, now I’ve been told I’ll need to use a BiPap machine (basically forced air to keep my airway open during sleep) for my apnea. Does anyone know if this will put me into the Exceptional Family Member category? We’re all so excited about this assignment, and I’d hate to lose it over this.
