Frequently Asked Questions

Do I need To Join an ACO?

No.  Doctors participate in ACOs.  Patients do not join ACOs, but may benefit by their doctors participating an ACO.


How Do I benefit if my physician Participates in an aco?

The doctors that participate in an ACO become a team that works together to provide you with coordinated care.  The ACO will provide your doctor with information and tools to better coordinate your care.  Your doctor will be able to see treatment and health issues treated by other doctors.  The ACO can also help coordinate care by having people call you after you have been in the hospital to make sure you have what you need.  The ACO can also help remind you when you are due for certain services or care.  You can also choose not to have your information shared with your doctor or the ACO (see instructions here).


Is an ACo the same as an hmo, insurance, or managed care?

No.  Unlike HMOs, managed care, or insurance plans, the ACO cannot tell you which providers you may see.  You will continue to enjoy all the same Medicare benefits and be protected by the same Medicare rights and protections.  If your doctor participates in an ACO, you still have the right to see any doctor that accepts Medicare at any time. 


How do I know if my physician is part of an aco?

If you aren’t sure if your doctor or healthcare provider is participating in a Medicare ACO, ask him or her.  If your doctor chooses to participate in an ACO, you will be notified.  The ACO may send you a letter to let you know that your doctor is participating in an ACO.  Your doctor may also have a sign in his or her office.  The doctor may also provide you with written information at your visit, or tell you that they are now part of an ACO.
