Ewa Beach Medigap switch guide: when insurers can ask health questions, and when they cannot

EWA BEACH, Hawaii — If you already have a Medicare Supplement (Medigap) policy and you are thinking about moving to a different one, the single most important question is not which plan looks better on paper. It is whether the new insurer is allowed to ask about your health — and, in some cases, turn you down or charge you more because of it. That answer depends on federal rules, a few state add-ons, and the timing of your request.

Here is what Ewa Beach residents should understand before they call an agent or fill out an application.

Your one guaranteed window: Medigap Open Enrollment

Your Medigap Open Enrollment Period is a six-month window that starts the month you are 65 or older and enrolled in Medicare Part B. During those six months, any insurer selling Medigap in Hawaii must sell you any policy they offer at the best available rate, regardless of your health history.

This window happens once. After it closes, the rules change — and that is where most of the confusion about "switching" comes from.

After open enrollment: medical underwriting is the default

Once your six-month window ends, insurers in most states — including Hawaii — are generally allowed to use medical underwriting if you apply for a new Medigap plan or want to switch from one to another. That means they can look at your health, ask about medications and conditions, and decide whether to accept you, charge more, or deny the application.

This is not a punishment. It is simply how Medigap works outside of the protected windows. It is also why many people keep the Medigap policy they picked at 65 for years, even if a different letter plan (like G or N) might look appealing later.

Federal guaranteed-issue rights: the exceptions that protect you

Federal law creates several "guaranteed-issue" situations where insurers cannot use underwriting against you, even after your open enrollment window has ended. These typically include:

• Your Medicare Advantage plan leaves the service area or stops offering Medicare coverage.
• You move out of your plan's service area.
• Your employer or union coverage that supplements Medicare is ending.
• Your Medigap insurance company goes bankrupt or you lose coverage through no fault of your own.
• You joined a Medicare Advantage plan when you first became eligible and want to switch back to Original Medicare within 12 months (the "trial right").

Each right has its own timing — usually 63 days from the qualifying event — and its own list of Medigap plan letters you are allowed to buy. The full rules are on Medicare.gov under Medicare Supplement Insurance.

State add-ons: birthday rules, anniversary rules, continuous open enrollment

A handful of states have added their own protections on top of the federal rules. Depending on the state, these can include:

• A birthday rule — a short window each year around your birthday when you can switch to a plan of equal or lesser benefits without underwriting.
• An anniversary rule — a similar window tied to the anniversary of your policy.
• Continuous or year-round open enrollment — some states let residents change Medigap plans without underwriting at any time, with conditions.

These rules vary a lot, and they change. Before you assume Hawaii does or does not offer one of these protections, confirm with the Hawaii SHIP (State Health Insurance Assistance Program) at 1-888-875-9229 or your state insurance department. They will tell you exactly what applies to your situation, at no cost.

The practical order of operations

Ewa Beach is in Honolulu County, and the county's Medigap market includes multiple carriers. If you decide to explore a switch, the safe order is:

1. Call Hawaii SHIP or check Medicare.gov to confirm whether a guaranteed-issue right or state rule applies to you. 2. Compare Medigap plans (the benefits within a letter, like Plan G, are standardized — the price and customer service are not). 3. Apply for the new plan and wait for written approval. 4. Only then, cancel your existing policy. Most insurers give you a 30-day "free look" period to review the new plan.

Cancelling first and applying second is the most common — and most costly — mistake.
