Medigap rates can vary based on carrier
Original Medicare (Part A and Part B) premiums are standardized by the federal government. Private insurance companies that offer Medicare Supplement Insurance plans, however, are free to set their own rates.
How a carrier rates (prices) its plans, inflation and other factors can cause premiums to change over time.
Certain Medigap plans that offer more benefits may cost more
Each type of Medicare Supplement Insurance plan offers a different combination of benefits standardized by the federal government. This means that rates may vary depending on the Medigap plan type.
Generally speaking, plans that offer more standardized benefits may cost more than plans with fewer benefits.

Medical underwriting could affect your Medigap plan rates
If you apply for a Medicare Supplement Insurance plan after your six-month Medigap Open Enrollment Period (OEP), you may be subject to medical underwriting.
- Your Medigap Open Enrollment Period starts as soon as you are at least 65 years old and enrolled in Medicare Part B.
- During the six months of your Medigap OEP, insurance companies cannot deny you a Medigap plan or charge you higher plan premiums based on your health.
But outside of your Medigap OEP, an insurance company reserves the right to determine your Medigap rates based on your health — unless you qualify for a guaranteed issue right.
Beneficiaries with certain health conditions might face higher rates because they are deemed to be riskier to insure, or they may be denied a Medigap plan altogether.
Insurance companies use different pricing structures to determine rates
There are three different pricing models that insurance companies can use to determine how your Medicare Supplement Insurance plan rates may increase in the future.
Each type of pricing system can produce a different rate for current and incoming plan members.
- Community-rated plans charge the same rate for every plan member, regardless of age. For example, a 75-year-old Medigap beneficiary with a community-rated plan will pay the same rate as a 65-year-old beneficiary with the same plan.
- Issue-age-rated plans have rates based on the age at which you purchased the plan. Your premium rate will be fixed and it won’t change as you age. While your initial Medigap rate could be higher than a community-rated plan, it could potentially cost less in the long term.
- Attained-age-rated plans have rates that increase as you age. As you get older, your Medigap rate will gradually go up.
Some insurance companies may offer Medigap plan discounts for women, non-smokers, married couples, those who pay their premium for the entire year and more.
Be sure to ask your plan provider if they offer any discounts before you sign up for a Medigap plan.
Medigap premiums may increase over time due to other factors, such as inflation.
