Brand New Day is a comprehensive Medicare Advantage Prescription Drug Health Plan that helps our members achieve optimal health for the whole person—physically, mentally and emotionally. Our health plan offers all the benefits of Original Medicare, plus so much more. We start where Medicare ends, giving members access to robust benefits with a personal touch—including dental, vision, chiropractic, unlimited transportation (to and from doctor visits), gym membership, home medical supplies and more. We provide many of the “extras”—plus compassionate one-on-one guidance, as well.
