Can You Be Denied Medicare Supplement Insurance?
Yes. A Medicare Supplement insurer can deny an application based on health in some circumstances.
Federal rules protect you during certain enrollment periods. Texas also has additional protections for some beneficiaries.
The key is knowing which rules apply when you submit your application.
Quick answer
- When: Enrollment protections depend on your situation.
- Health questions: They may apply outside protected periods.
- Before switching: Confirm approval and start dates.
When can a Medigap insurer deny you?
After your protected Medigap Open Enrollment Period ends, an insurer may generally review your medical history and decide whether to offer a policy.
This process is called medical underwriting.
Companies use their own guidelines, so a condition accepted by one insurer may be treated differently by another.
Underwriting may involve questions about diagnoses, recent hospital stays, upcoming surgery, medications, or the need for help with daily activities.
The existence of a condition does not automatically mean every company will decline you.
When can you not be denied because of health?
Your six-month federal Medigap Open Enrollment Period begins the first month you are at least 65 and enrolled in Part B.
During that time, insurers generally must offer you any Medigap plan they sell that is available to you and cannot charge more because of your health.
You may also qualify for a guaranteed-issue right after certain losses of coverage or under a Medicare Advantage trial right.
The plans you can buy and the deadlines depend on the qualifying event.
What if you have Medicare before age 65?
Texas has additional protections.
Beneficiaries under 65 with Medicare because of disability generally have a six-month open enrollment opportunity for Medigap Plan A when they enroll in Part B.
Texas provides different plan and premium rules for people under 65 who qualify through ESRD or ALS.
People who become eligible for Medicare before 65 also receive a new six-month Medigap open enrollment opportunity at 65.
Do not assume the under-65 plan restrictions continue after that birthday.
What about pre-existing conditions?
A pre-existing condition is not a valid reason for a health-based denial during protected Medigap enrollment.
However, in limited situations, a policy may delay coverage for pre-existing conditions for up to six months.
Prior creditable coverage can reduce or eliminate that waiting period.
This is not the same as a six-month delay before the policy starts.
Other covered services can still be covered while a qualifying pre-existing condition waiting period applies.
Ask the insurer for a written explanation of any limitation.
Can your current Medigap insurer drop you if you get sick?
Generally no. Medicare Supplement policies are guaranteed renewable.
The insurer cannot cancel an existing policy simply because you develop cancer, diabetes, heart disease, or another medical condition.
Limited exceptions to guaranteed renewability include nonpayment of premiums and material misrepresentations, subject to applicable law.
Premiums can increase according to applicable rating rules, but a claim or new illness alone does not end guaranteed renewability.
What to do after a denial
Keep any current policy in force.
Ask the insurer to explain the reason for the decision and check whether medical information was recorded correctly.
Review whether a federal guaranteed-issue right or additional state protection applies.
If you believe an insurer improperly denied a protected application, contact the Texas Department of Insurance.

Do not assume a denial from one company proves that every other insurer will reach the same decision.
Example: applying after a protected window
A 70-year-old person who has Original Medicare but never purchased Medigap may apply for Plan G.
If their initial protected period ended years ago and no guaranteed-issue event applies, the insurer may require medical underwriting.
By contrast, a person turning 65 and newly enrolled in Part B can use the federal six-month window without health-based rejection.
The same medical condition can therefore lead to different application rights depending on timing.
Frequently asked questions
Can diabetes cause a Medigap denial?
Outside protected periods, an insurer may consider diabetes under its underwriting guidelines.
During protected enrollment, health-based denial is generally prohibited.
Can an insurer charge more because of health?
Not during protected Medigap open enrollment or an applicable guaranteed-issue right.
Outside those protections, underwriting and pricing rules may differ.
Does a denied replacement application cancel my existing plan?
No. A declined new application does not automatically end an existing policy.
Can I be denied if I have cancer?
An insurer may consider cancer history outside protected enrollment; the details and the insurer's criteria matter.
Does a pre-existing condition waiting period mean I have no insurance?
No. A limited waiting period concerns certain pre-existing conditions, not necessarily all benefits.
Where can I challenge a denial?
You can request clarification from the insurer and contact the Texas Department of Insurance if you believe your rights were violated.
