Same Medigap Plan G in Cincinnati: what really changes when you switch insurers

CINCINNATI — If you have started shopping for a Medicare Supplement (Medigap) policy in Cincinnati, you have probably noticed something confusing. Two insurers offer "Plan G." The coverage looks identical on paper. But the premiums, the discounts and even the questions the insurer asks you can look nothing alike.

That is not a mistake. It is how Medigap is designed. The letters — A, B, D, G, G-HD, K, L, M and N for people newly eligible today — are standardized by federal law, so a Plan G is a Plan G no matter whose name is on the envelope. What insurers compete on is everything around the coverage: how they price it, how they raise it over time, whether they give a household discount, and how strictly they underwrite.

Here is how to compare the same plan letter across insurers selling in Cincinnati, which is in Hamilton County.

Start with the letter, not the insurer

Because Medigap letters are standardized, the benefits inside Plan G are identical from one insurer to the next. So are Plan N's, Plan K's, and so on. If Plan G covers the Part A deductible at one company, it covers it at all of them.

That means your first decision is which letter fits how you use care — not which brand-name insurer you have heard of. Once you have picked a letter, then you compare insurers on that same letter, apples to apples.

Plans C and F are only available to people who were eligible for Medicare before January 1, 2020. Everyone newly eligible today chooses from the remaining letters.

How Ohio insurers price the same plan letter

This is where identical coverage starts to cost very different amounts. Ohio insurers may use any of three pricing methods, and it is worth asking which one applies before you sign anything.

• Attained-age rated. Your premium is based on your current age and goes up as you get older. It often looks cheapest at 65 and climbs from there.
• Issue-age rated. Your premium is based on the age you were when you first bought the policy. It does not go up simply because you had a birthday, though it can still rise for other reasons like inflation and claims.
• Community-rated. Everyone in Ohio who buys that policy pays the same base premium regardless of age.

None of these methods is automatically better — they just age differently. A community-rated policy might cost more at 65 and less at 80 compared with an attained-age policy on the same letter.

Rate history matters more than the first-year price

Every Medigap premium can go up over time, no matter the pricing method. What separates insurers is how often and how much they have raised rates in the past.

The Ohio Department of Insurance publishes a Medigap rate guide that shows premium ranges and, in many cases, historical rate changes for insurers selling in the state. A company with a modest first-year price and a pattern of large yearly increases can end up costing more than a company that started higher and held steady.

Ask any agent — or the insurer directly — for the rate increase history on the specific plan letter you are considering in Ohio.

Household discounts and other differences

Even on the same plan letter, insurers can offer:

• Household or spousal discounts when two adults in the same home each buy a policy from the same company. The percentage varies.
• Different payment methods (electronic funds transfer, annual pay) that may knock a bit off the premium.
• Different customer service and claims processes, which do not appear on any price sheet but matter when you actually need to use the coverage.

These extras will not change what the policy covers, but they can meaningfully change what you pay and how the experience feels.

Underwriting: when insurers can ask about your health

Timing is the quietest and most important part of Medigap shopping.

During your six-month Medigap Open Enrollment Period — which starts the month you are 65 or older and enrolled in Part B — insurers in Ohio must sell you any Medigap plan they offer at their best available rate, regardless of your health. This is called guaranteed issue.

Outside that window, most insurers can use medical underwriting. That means they can ask health questions, look at prescription history, and either charge more or decline you outright. Two people applying to the same insurer for the same Plan G, one inside their open enrollment window and one outside, can get very different answers.

There are limited guaranteed-issue rights outside open enrollment (for example, if you lose other coverage). Ohio SHIP counselors can walk you through whether you qualify.
