Medicare Supplement underwriting is the process an insurance carrier may use to evaluate an applicant's eligibility for a Medigap policy based on health history and other information requested on the application.
For insurance agents, however, underwriting should not automatically be the first step.
Before asking whether a client can pass medical underwriting, determine whether the client has an enrollment protection that could allow them to obtain or change Medicare Supplement coverage without underwriting. That could include the federal Medigap Open Enrollment Period, a guaranteed-issue right, or a state-specific Birthday Rule or similar switching protection.
And when underwriting is required, newer carrier approaches—such as Mutual of Omaha's Medicare Supplement tiered-rating initiative scheduled for August 28, 2026—may create additional placement opportunities for some applicants.
The goal is not simply to ask, “Will this client pass underwriting?”
A better question is:
What legitimate path to Medicare Supplement coverage is available to this client?
Medical underwriting often becomes relevant when someone wants to buy or switch Medicare Supplement coverage outside a protected enrollment situation.
According to Medicare.gov's Medigap guidance, people who are 65 or older generally receive a one-time, six-month Medigap Open Enrollment Period beginning the first month they have Medicare Part B. During this period, an insurance company cannot deny an applicant a Medigap policy because of pre-existing health problems.
After that enrollment period ends, the situation can be different. Medicare.gov explains that an applicant may not be able to purchase a Medigap policy later, or the policy may cost more, unless another protection applies.
That makes the first step in a Medicare Supplement review a rights-and-eligibility check—not a health questionnaire.
Before moving into medical underwriting, answer three questions:
Medicare.gov defines guaranteed-issue rights as certain situations in which an insurance company cannot deny an eligible person a Medigap policy.
These rights may apply outside the initial Medigap Open Enrollment Period under specific circumstances.
Agents should verify the client's exact situation, applicable deadline, documentation requirements, and available policy choices rather than assuming that any loss or change of coverage creates guaranteed issue.
This is an important distinction for clients.
The annual Medicare Open Enrollment Period is not the same as the Medigap Open Enrollment Period.
Medicare.gov explains that, under federal law, people generally do not have a right to switch Medigap policies unless they are still within their six-month Medigap Open Enrollment Period or qualify for a specific guaranteed-issue situation.
But federal law is only part of the analysis.
States may provide additional opportunities.
A growing number of states have enacted Birthday Rules or similar protections that can give existing Medicare Supplement policyholders an annual opportunity to change qualifying Medigap coverage without medical underwriting.
These rules can be especially important for clients who might otherwise have difficulty passing traditional underwriting.
They can also create a valuable annual service opportunity for agents.
PSM's Medicare Supplement Birthday Rule guide tracks this developing trend and explains how agents can use these windows for client reviews, retention, and prospecting.
The important qualification is that there is no single national Birthday Rule.
Depending on the state, requirements may differ regarding:
Because these protections continue to evolve, agents should verify the current rule with the applicable state insurance department before representing a switch as guaranteed issue.
Birthday Rule states can also create a practical client-retention system.
Consider adding relevant dates to your CRM and creating reminders before each client's eligible window.
An annual Medicare Supplement review can give you an opportunity to discuss:
Not every review needs to result in a replacement. Sometimes staying put is the right outcome.
The value is in giving clients a reason to review their coverage with you before responding to an advertisement or another agent.
When no federal or state enrollment protection applies, medical underwriting may become part of the application.
There is no universal Medicare Supplement underwriting questionnaire used by every insurer.
Depending on the carrier and application, underwriting may consider information such as:
Agents should use the current carrier application and underwriting guide for the applicant's state as the operational reference.
Never assume that underwriting criteria from one carrier apply to another.
Good pre-screening can help agents identify likely conflicts with published underwriting guidelines before an application is submitted.
But pre-screening is not approval.
Avoid statements such as:
A better way to set expectations is:
“Based on the carrier's current underwriting guidelines, this appears worth submitting. The carrier will make the final underwriting decision.”
That gives the client useful guidance without promising an outcome the agent does not control.
Traditional Medicare Supplement underwriting can feel binary:
Approved at the available rate → or declined.
Some carrier strategies are creating additional possibilities.
Mutual of Omaha has implementing a Medicare Supplement Tiered Rating Program. The concept is important for agents because it may create another possible placement outcome for certain applicants who do not qualify for the carrier's standard rate.
Instead of thinking only:
Standard approval → decline
the underwriting conversation may include:
Standard approval → alternative rated offer when available → decline
That distinction could make certain cases worth another look.
PSM is tracking the program in its Medicare insurance news and agent updates, and agents interested in the carrier can also review PSM's Mutual of Omaha Medicare Supplement resources.
Tiered underwriting should not be positioned as guaranteed acceptance.
An applicant's complete health and insurance profile still matters, and the carrier makes the underwriting determination.
Agents should also avoid assuming that one diagnosis, prescription, or health condition automatically places an applicant into a specific rate tier.
Use the current Mutual of Omaha underwriting materials for the applicant's state and verify the program's availability before making recommendations.
A new underwriting pathway also creates a prospecting opportunity.
Think about clients and prospects who previously:
Some of these cases may deserve to be reviewed again as carrier underwriting programs evolve.
That does not mean every previously declined applicant will qualify.
It means an old underwriting decision should not automatically become a permanent assumption about every future carrier or product opportunity.
Agents can use the following sequence when evaluating a new Medicare Supplement application or replacement.
Confirm the client's:
If the client is within the federal Medigap Open Enrollment Period, medical underwriting generally should not be used to deny coverage due to health problems.
Determine whether the client's circumstances create a federal Medigap protection.
Use current Medicare.gov guaranteed-issue information rather than relying on memory.
Determine whether the state has:
Use PSM's Birthday Rule overview as an agent resource, then verify the current rule through the state insurance regulator.
If underwriting is necessary, determine which carriers and Medigap plans are currently available for the applicant.
PSM's Medicare solutions for insurance agents can help agents explore Medicare Supplement and other Medicare product opportunities.
Availability and underwriting requirements vary by state and carrier.
Do not rely on an old underwriting guide.
Check:
Where available, determine whether a carrier offers an alternative underwriting pathway such as Mutual of Omaha's upcoming tiered-rating approach.
This may give some applicants another potential path besides standard-rate approval or decline.
Review the client's situation against current guidelines.
The purpose is to identify potential fits—not manipulate the answers to make the client appear eligible.
Help the applicant answer questions truthfully and completely.
Medicare.gov advises applicants to fill out a Medigap application carefully and completely, including answering medical questions when applicable.
If an application question is unclear, get clarification rather than guessing.
Tell the client that the carrier may request additional information.
Depending on the case, underwriting can result in:
A submitted application is not the same thing as approved coverage.
Do not encourage a client to cancel existing Medicare Supplement coverage solely because another application has been submitted.
Mutual of Omaha similarly notes in its Medicare Supplement Plan G guidance that applicants switching coverage may have to undergo underwriting and should not cancel their current plan until the new plan has been approved.
A client may not need medical underwriting at all.
Check federal and state protections first.
Medigap is affected by state-specific requirements and protections.
A Birthday Rule or other switching opportunity in one state should not be assumed to apply in another.
It does not create a general federal guaranteed right to change Medicare Supplement policies every fall.
The rules governing Medigap and Medicare Advantage are different.
Health questions, lookback periods, and underwriting approaches can differ.
Always use the current carrier materials.
Only the carrier can make the final underwriting determination.
The goal is an accurate application.
Help clients understand the questions and provide complete answers—not find creative ways around the questions.
Underwriting criteria can vary among carriers and change over time.
New programs such as tiered rating can also create placement possibilities that did not previously exist.
Review current options before concluding that the client cannot obtain Medicare Supplement coverage.
Before submitting an application:
No.
During the federal Medigap Open Enrollment Period, eligible beneficiaries have protections that prevent an insurer from denying a Medigap policy because of pre-existing health problems. Federal guaranteed-issue rights and additional state protections may also allow someone to obtain coverage without traditional medical underwriting.
Outside protected enrollment situations, an insurer may not be federally required to sell an applicant a Medigap policy.
The outcome can depend on applicable federal protections, state law, carrier availability, and carrier underwriting requirements.
There is no general federal right to change Medigap policies every year without underwriting.
Some states, however, offer Birthday Rules or similar annual switching protections. Review PSM's Birthday Rule guide for Medicare Supplement agents and verify the current state requirements before advising a client.
No.
Carriers can use different applications, health questions, underwriting criteria, and processes. State-specific requirements may also apply.
An agent can use carrier guidelines to pre-screen a case, but the carrier makes the final underwriting decision.
Do not guarantee approval.
The approach may provide another potential underwriting outcome for certain applicants who do not qualify for the carrier's standard rate. It should not be interpreted as guaranteed coverage.
Agents should verify the current Mutual of Omaha underwriting guide, state availability, and implementation details before submitting an application.
The strongest Medicare Supplement agents do more than memorize health questions.
They understand the order in which opportunities should be evaluated:
Federal enrollment protection → state protection → carrier fit → underwriting pathway → application → follow-up.
That distinction matters.
A client who looks difficult to place through traditional underwriting may qualify for a Birthday Rule or other guaranteed-issue opportunity. Another applicant may fit a different carrier's underwriting guidelines. Newer strategies such as tiered rating may provide another option in markets where they are available.
The goal is not to work around underwriting.
It is to understand all legitimate ways to help a client pursue appropriate Medicare Supplement coverage before concluding that an option is unavailable.
PSM Brokerage supports independent insurance agents with product access, contracting assistance, training, marketing resources, technology, and experienced back-office support.
Explore PSM's Medicare solutions for insurance agents, review the Medicare Supplement Plan N agent guide, or learn more about Mutual of Omaha Medicare Supplement plans.
Working independently does not mean handling every underwriting question alone. When a case becomes complicated, having access to current carrier information and experienced support can help agents evaluate the available paths more efficiently.
For agent education only. Medicare Supplement availability, underwriting requirements, carrier programs, rates, guaranteed-issue protections, and state rules vary and may change. Verify current requirements with the applicable carrier, Medicare.gov, and state insurance regulator before advising a client. Mutual of Omaha tiered-rating information reflects PSM information available as of August 13, 2026; the program is scheduled to become effective August 28, 2026, and current implementation details should be verified before use.
