Why Does the Same Medigap Plan Letter Cost More From One Company?

You have two quotes for the same Medicare Supplement Insurance plan letter. One costs more. That does not necessarily mean it pays more.

Medigap policies with the same letter generally provide the same standardized basic benefits, regardless of the insurance company selling them. The premium can still differ because each insurer sets its own price and applies its own rating method, discounts and underwriting rules. Medicare explains that distinction in its Medigap materials, collected on the Sources page.

Your job is not to find a universal price. There is not one you can safely use. Your job is to make each insurer answer the same questions, in writing when possible, and then call for the rate that applies to the person, ZIP code and application in front of you.

Who pays

Original Medicare pays first for covered services. A Medigap policy can pay some of the deductibles, coinsurance and copayments left behind, depending on the plan letter. You pay the Medigap premium directly to the private insurer. Prescription drug coverage is separate, and a Medigap policy is not long-term care insurance.

Start by confirming that you are actually comparing the same plan letter. A different letter means a different package of benefits. If the letters match, a higher premium does not add extra standardized benefits merely because the company charges more.

Do not compare a Medigap premium with a Medicare Advantage premium as though the products work the same way. Medigap supplements Original Medicare. Medicare Advantage provides Medicare benefits through a private plan with its own rules, network and cost sharing. If that is the decision you are making, get free plan counseling before changing coverage.

The papers

Put one worksheet beside the phone. Give every insurer the same facts and record the name of the plan letter, the quoted premium, how often it is billed and how long the quote is valid. Then ask these questions:

Is this policy community-rated, issue-age-rated or attained-age-rated? Medicare describes these as different ways insurers may price Medigap policies. Under a community-rated method, age alone does not set your premium. Under an issue-age method, the age when you buy affects the starting price. Under an attained-age method, the premium can rise as you grow older. Premiums may also change for reasons such as inflation or health care costs, so the rating label is not a promise that a price will stay fixed.

Does the quote include every available discount? Ask about household, electronic payment and other discounts. Get the eligibility rule, the discount amount and the conditions for keeping it. A discount shown in a sales conversation is not useful unless you know whether it appears in the written quote and whether it can end.

Was tobacco use included correctly? Was the correct ZIP code used? Is the premium based on answering health questions, or does a guaranteed-issue right apply? Small differences in the application facts can produce different quotes, so read the completed application before signing it.

Ask for the policy's Outline of Coverage. Match the plan letter and benefit description to the quote. Also ask whether the policy includes benefits beyond the federally standardized package, and whether those extras can be removed or changed. Do not pay more for an extra until you know what document controls it.

Finally, ask the insurer for its rate increase history for that exact policy form in Missouri. Past changes cannot tell you the next premium, but the record gives you something more useful than a salesperson's reassurance. Send every unresolved rate question to the insurer's published phone number and write down the answer, representative and call reference number.

The runway

Your enrollment rights can matter more than the first premium. During a Medigap open enrollment period, an insurer generally cannot use medical underwriting to deny a policy or charge more because of health problems. Certain other situations create guaranteed-issue rights. Outside those protections, an insurer may be allowed to ask health questions, deny an application or change the offered price, subject to applicable rules.

Do not cancel an existing Medigap policy because a new quote looks better. First get the new insurer's acceptance, effective date and final premium in writing. Confirm when the first payment is due and when coverage begins. Then coordinate the old policy's end date so you do not create a gap or pay indefinitely for two policies.

If you are leaving Medicare Advantage for Original Medicare, confirm that the change is permitted and that the Medigap policy can begin when you need it. The insurer, Medicare and a Missouri SHIP counselor should all be working from the same effective-date plan before you sign a cancellation request.

Keep the quote, completed application, Outline of Coverage, acceptance notice, premium notice and cancellation confirmation together. If the issued premium differs from the quote, stop and ask the insurer to identify the application fact or rating rule that changed it.

Free help

Missouri SHIP provides free Medicare counseling and does not sell insurance. A counselor can help you identify the plan letters being compared, understand enrollment protections and prepare questions for insurers. Use the contacts on Local Help With Paying for Care.

For the exact premium, call the insurer. For Medicare enrollment and guaranteed-issue rules, use Medicare or Missouri SHIP. If the dispute turns on what an agent promised, what the issued contract says or whether Missouri insurance law was followed, stop at the document trail and take the file to the appropriate regulator or a lawyer. This desk does not decide that dispute.
