How to Transition to Your New ACA Health Plan in the New Year

Cynthia Macluskie • January 23, 2026

If you recently enrolled in a new Medicare plan during the Annual Enrollment Period (AEP), your coverage likely started on January 1st. Whether you switched Medicare Advantage plans, changed Part D drug coverage, or moved between Original Medicare and a Medicare Advantage plan, it’s important to make a smooth transition.


Here are some tips to help you get started with your new plan:


1. Watch for Your New Plan Materials


You should receive a welcome packet and a new member ID card from your plan. Be sure to review these materials carefully. They’ll include important details about your coverage, provider networks, drug formularies, and how to get care.


2. Share Your New Card with Providers


Give your new Medicare Advantage or Part D card to your doctor, pharmacy, and any specialists you see. This ensures your care is billed correctly from day one.


3. Double-Check Your Coverage


Even if you already reviewed your benefits before enrolling, it’s smart to confirm:


  • Your doctors and pharmacies are in-network (if applicable)
     
  • Your medications are covered and fall within the plan’s formulary
     
  • You understand copays and other out-of-pocket costs
     

4. Prepare Your Prescriptions for the First 30 Days


If your medications or providers have changed, plan ahead to avoid any disruptions. Refill prescriptions early if possible, and call your plan’s customer service if you have any trouble getting your medications or setting up care.


5. Keep an Eye on Your Mail


You may receive additional documents throughout the year, like Explanations of Benefits (EOB) when you receive plan services, or plan updates. Don’t ignore them—these may contain information about your costs or changes to provider networks.

Arizona Health Care Cost Containment System recently updated the ABA policy, and it is now open for public comment. There are many positive improvements within the proposal, including stronger fingerprinting, criminal background check, and abuse registry requirements for certain ABA providers. However, I do not believe the proposed protections go far enough. Children and vulnerable adults receiving ABA services often interact with many individuals throughout the day beyond credentialed clinical staff. Front office personnel, float staff, transportation staff, aides, interns, volunteers, and others may all have access to vulnerable members. Safety standards should not depend on a billing code or job title. They should depend on access to a vulnerable person. Any individual who may supervise, transport, escort, monitor, or otherwise interact with a vulnerable member should be required to complete fingerprinting, criminal background checks, and abuse registry screening before member contact occurs. In addition, providers serving vulnerable populations through Arizona Department of Economic Security Division of Developmental Disabilities, AHCCCS, and contracted health plans should all be held to the same strict safety standards. Protecting vulnerable children and adults should always be the priority.
