An appeal is a formal way of asking us to review and change a coverage decision we made. The appeals process can differ depending on what type of medical service you’re trying to appeal. You can learn more about how to appeal a coverage decision for medical coverage or prescription drugs at our appeals and grievances center.

There are two main time periods when you can change or leave your Medicare Advantage (Part C) or prescription drug (Part D) plan.


During Medicare's annual election period: 10/15 – 12/7


From October 15 through December 7 each year, you can decide to keep your current plan or select a new plan. Your coverage will begin on January 1 of the following year, if we get your request during the annual election period.


Medicare beneficiaries may also enroll in an Aetna Medicare plan through the CMS Medicare Online Enrollment Center located at


During a special enrollment period granted to you for certain situations


In certain situations, you can change your Medicare plan outside of Medicare’s annual election period. Some examples include if you:


  • Move out of your plan’s service area
  • Lose other creditable prescription drug coverage (prescription drug coverage that pays out, on average, at least as much as a Medicare Part D plan)
  • Live in a long-term care facility (like a nursing home)
  • Have Medicaid


If you get coverage from an employer or group health plan, review the information they provided to see what options are available to you.


Generally, your membership on your current plan will end on the last day of the month after we get your request to switch to Original Medicare or another plan.

If you’re enrolled in a standard Aetna Medicare Plan (HMO)

If you get coverage from an out‐of‐network provider, your plan won’t cover their charges. Medicare and Aetna Medicare won’t be responsible either.


Generally, you must get your health care coverage from your primary care provider (PCP). Your PCP will issue referrals to participating specialists and facilities for certain services. For some services, your PCP is required to obtain prior authorization from Aetna Medicare.


You’ll need to get a referral from your PCP for covered, non‐emergency specialty or hospital care, except in an emergency and for certain direct‐access service. There are exceptions for certain direct access services.


You must use network providers, except for:

  • Emergency or urgent care situations
  • Out‐of‐area renal dialysis

If you get routine care from out‐of‐network providers, Medicare and Aetna Medicare won’t be responsible for the costs.


If you’re enrolled in Aetna Medicare Plan (PPO)


You have the flexibility to receive covered services from network providers or out‐of‐network providers. Out‐of‐network/non‐contracted providers are under no obligation to treat Aetna Medicare members, except in emergency situations. For a decision about whether we’ll cover an out‐of-network service, we encourage you or your provider to ask us for a pre‐service organization determination before you receive the service. Please call us or see your Evidence of Coverage for more information, including the cost share for out‐of‐network services.


If you receive covered services from an out‐of-network provider, it’s important to confirm that they:

  • Accept your PPO plan
  • Are eligible to receive Medicare payment  

Aetna provides a directory for providers in Spanish.

Sometimes you need a referral or prior authorization before you can get care. A referral is a kind of preapproval from your primary care provider to see a specialist. A prior authorization or precertification is when your provider has to get approval from us before we cover an item or service. Prior authorizations are often used for things like MRIs or CT scans. Your provider is in charge of sending us prior authorization requests for medical care.


View this list to find out what services and drugs require approval


Each plan has rules on whether a referral or prior authorization is needed. Check your plan’s Evidence of Coverage (EOC) to see if or how these rules apply.


Tip: If you’re viewing an EOC online, you can simply press Ctrl + F to search for an item. You can find most rules for referrals or prior authorizations in Chapter 4 — Benefits Chart — of the EOC.


Medicare Part B:

You can get some diabetic supplies, including durable medical equipment (DME), with your Medicare Advantage (MA) and Medicare Advantage Prescription Drug plans (MAPD).

  • Insulin infusion pump and most insulins used in the pump
