Switching from a Medicare Advantage (MA) plan back to Original Medicare (Parts A and B) can be relatively simple from a procedural standpoint, but it’s the potential for medical underwriting to secure a Medigap (Medicare Supplement) policy that can make the transition difficult and costly. The level of difficulty depends largely on your health status and whether you qualify for a special enrollment period that includes guaranteed-issue rights for a Medigap policy.
The procedural ease of switching back
For most people, the physical act of switching is not hard, especially if you act during a designated enrollment period. The key is understanding when and how you can make the change. There are two primary periods for switching:
- Medicare Annual Enrollment Period (AEP): From October 15 to December 7 each year, you can switch from an MA plan to Original Medicare. Your coverage will begin on January 1 of the following year.
- Medicare Advantage Open Enrollment Period (MA OEP): From January 1 to March 31, if you are already in an MA plan, you can switch to Original Medicare. Changes take effect the first day of the month after the plan receives your request.
To make the switch during these times, you can simply call 1-800-MEDICARE or enroll in a standalone Medicare Part D prescription drug plan, which will automatically disenroll you from your MA plan.
The hidden challenge: Medigap and medical underwriting
While the enrollment procedure is simple, the biggest challenge is what comes next. Original Medicare covers about 80% of your outpatient medical costs, leaving you responsible for the remaining 20% coinsurance without a built-in out-of-pocket maximum. Most beneficiaries on Original Medicare purchase a Medigap policy to cover these costs and provide financial protection.
The difficulty arises because in most states, if you are outside your initial 6-month Medigap Open Enrollment Period (which starts when you enroll in Part B), insurers can use medical underwriting to assess your health. This means they can:
- Deny you a Medigap policy based on pre-existing conditions.
- Charge you a higher premium.
- Impose a waiting period for pre-existing conditions.
This is why switching can be so challenging, especially for those with significant health issues. The inability to secure a Medigap plan can leave you with substantial and uncapped out-of-pocket costs on Original Medicare, creating a strong financial disincentive to switch.
When is it not hard to get a Medigap policy?
There are specific situations where you have guaranteed-issue rights, meaning insurance companies cannot use medical underwriting to deny you a Medigap policy or charge you more due to your health. These include:
- Trial Right: If you enrolled in an MA plan when you first became eligible for Medicare and switch back within the first 12 months, you can get a Medigap policy without underwriting.
- Moving Out of Area: If you move out of your MA plan's service area and switch back to Original Medicare, you have guaranteed-issue rights for a Medigap policy.
- Involuntary Termination: If your MA plan terminates its contract with Medicare or leaves your area, you have guaranteed-issue rights when switching back.
How the Medigap situation differs by state
It is important to note that state-specific laws can provide additional protections. For instance, a small number of states offer year-round or alternative guaranteed-issue periods for Medigap policies. In these states, it is much easier to switch from an MA plan to Original Medicare and obtain supplemental coverage without facing medical underwriting. Check with your State Health Insurance Assistance Program (SHIP) to understand your specific rights.
A comparison of switching scenarios
| Aspect | Procedural Switch (e.g., during AEP/MA OEP) | Medical Underwriting for Medigap | Guaranteed-Issue Right Scenario | State-Specific Laws |
|---|---|---|---|---|
| Ease of Process | Simple and straightforward via phone or enrolling in a Part D plan. | Potentially difficult, especially with pre-existing conditions. | Very simple, as insurers cannot deny coverage. | Can provide additional protections beyond federal law, simplifying the process. |
| Main Hurdle | Timing the switch to a valid enrollment period. | Passing the medical underwriting process to get a Medigap policy. | Ensuring you qualify for the specific guaranteed-issue right. | Awareness of and eligibility for specific state-level policies. |
| Resulting Costs | Potentially higher, uncapped out-of-pocket costs without a Medigap policy. | Higher premiums or denial of coverage, potentially leading to high out-of-pocket costs. | Normal Medigap premiums for your age and location, no penalty for pre-existing conditions. | Can protect against higher rates based on health status. |
| Additional Coverage | Must purchase a standalone Part D plan for drug coverage. | Need to separately secure Part D plan, and Medigap policy may be expensive or unavailable. | Can get a Medigap and standalone Part D plan without health-related issues. | Same as other scenarios, with potential for broader Medigap access. |
Conclusion: Consider your health status and timing
For a healthy individual, the process of switching from Medicare Advantage to Original Medicare is procedurally easy during the open enrollment periods. However, for those with pre-existing health conditions, the process can be much harder and more expensive due to the loss of Medigap guaranteed-issue rights after their initial enrollment period. It is crucial to evaluate your health, coverage needs, and financial situation. If you have significant health issues, switching without a guaranteed-issue right could lead to substantial and uncapped out-of-pocket expenses. Therefore, the difficulty is not in the enrollment mechanics but in the financial consequences of securing adequate supplemental coverage based on your health history. Always consult resources like your local SHIP to understand your options before making a decision.
What to consider before switching
- Evaluate your current plan satisfaction: Are you unhappy with provider network restrictions or prior authorization requirements? These are common reasons to switch.
- Compare costs: Look at the total cost of your MA plan versus the projected costs of Original Medicare plus a Medigap and Part D plan. Consider your potential uncapped expenses on Original Medicare without supplemental insurance.
- Check Medigap eligibility: Determine if you have guaranteed-issue rights to a Medigap policy. If not, be prepared for medical underwriting and potential denial or higher premiums.
- Review your doctors and hospitals: With Original Medicare, you can see any provider in the U.S. who accepts Medicare. Ensure your current doctors accept Original Medicare and that this flexibility is important to you.
- Plan for prescription drugs: If you switch, you must enroll in a separate Part D plan. Failing to do so promptly can result in a late enrollment penalty.
How to make the switch
- Time your switch: Ensure you are within a valid enrollment period, such as the AEP (Oct 15 - Dec 7) or MA OEP (Jan 1 - Mar 31).
- Contact your insurer or Medicare: Inform your MA plan of your decision to disenroll. You can also call 1-800-MEDICARE to process your disenrollment.
- Enroll in Part D: Select and enroll in a standalone prescription drug plan. This action will automatically cancel your MA plan and return you to Original Medicare.
- Apply for Medigap: If eligible and desired, apply for a Medigap policy. If you don't have guaranteed-issue rights, you will undergo medical underwriting.
- Inform your providers: Notify your healthcare providers of your new coverage to avoid billing issues.

The "trap" to avoid: Health-based Medigap denial
The biggest risk in switching is falling into the so-called "Medicare Advantage trap," where a beneficiary with a new or worsened health condition wants to switch but cannot affordably obtain a Medigap policy because they are outside a guaranteed-issue period. This situation can leave individuals with significant, ongoing out-of-pocket costs. To avoid this, it is critical to understand your rights and timing before making any changes. Consulting with a State Health Insurance Assistance Program (SHIP) counselor is a wise move for personalized guidance.
