Can You Switch Medigap Plans in Perth Amboy? Timing Rules

# Thinking of Switching Medigap? Read This First, Perth…

PERTH AMBOY, N.J. — If you have a Medicare Supplement (Medigap) policy and you've been wondering whether you can move to a different one, the short answer is: sometimes yes, sometimes only if a company approves you, and sometimes on a specific window tied to your birthday or policy anniversary. The rules are a mix of federal protections and state add-ons, and knowing which one applies to you is what makes a switch smooth instead of stressful.

Perth Amboy is in Middlesex County, and readers here ask about switching Medigap all the time — usually after a rate increase notice or a change in health. Here's how the timing works.

The one window where switching is easiest

Your strongest protection comes during your Medigap Open Enrollment Period — the six months that start the month you're 65 or older AND enrolled in Part B. During that window, an insurer must sell you any Medigap policy it offers, at the best available rate for your age, without asking health questions.

That window only happens once. After it closes, switching Medigap is a different conversation.

What "medical underwriting" really means

Outside of your open enrollment or a guaranteed-issue right, most states allow insurers to use medical underwriting when you apply for a new Medigap policy. That means the company can ask about your health history, and it can:

• Approve you at standard rates,
• Approve you at a higher rate,
• Delay coverage for a pre-existing condition, or
• Turn down your application.

This is why many people shop before they have a serious health change — not after. It's also why it's worth keeping your current policy in force until a new one is officially approved.

Federal guaranteed-issue rights

Federal law gives you a guaranteed-issue right — the right to buy certain Medigap policies without underwriting — in a handful of situations. Common examples from medicare.gov include:

• Your Medicare Advantage plan leaves Medicare or stops serving your area.
• You move out of your plan's service area.
• You joined a Medicare Advantage plan when you first became eligible for Medicare and want to switch back within 12 months (a "trial right").
• Your employer or union coverage that pays after Medicare is ending.
• Your Medigap insurance company goes bankrupt or misled you.

These rights come with tight deadlines — often 63 days — so the day you get a notice of coverage ending is the day the clock starts. Save every letter.

The state layer: birthday, anniversary and year-round rules

On top of federal protections, some states have added their own. You may have heard about:

• Birthday rules in states like California and Oregon, which let you switch to an equal or lesser Medigap plan around your birthday without underwriting.
• Anniversary rules in a few states, tied to the anniversary of your policy.
• Continuous or year-round open enrollment in states like New York and Connecticut, where insurers can't turn you down based on health at any time.

Whether New Jersey has one of these added protections — and exactly how it would apply to a Perth Amboy resident — is something you should confirm directly, because state rules change. The two best sources are New Jersey's SHIP (called SHIP in New Jersey, run through the Department of Human Services) and the New Jersey Department of Banking and Insurance. You can also call 1-800-MEDICARE and ask them to walk you through your options.

Practical steps before you apply

If you're seriously thinking about switching:

1. Read your current policy's renewal notice. Understand what's changing and why. 2. Compare letter plans, not just companies. A Plan G from one insurer covers the same core benefits as a Plan G from another; price and customer service are where they differ. 3. Ask whether underwriting applies. If you're outside your open enrollment and don't have a guaranteed-issue right, the insurer will likely ask health questions. 4. Don't cancel your old policy first. Wait until the new one is approved and effective. Medigap policies generally include a 30-day "free look" period. 5. Get help. SHIP counseling is free and unbiased.

What switching Medigap doesn't affect

Changing Medigap policies doesn't change your Part A, Part B, or Part D drug coverage. Those are separate. Part D has its own annual dates to remember — Open Enrollment runs Oct. 15 through Dec. 7 — and for 2026, Part D has an annual out-of-pocket cap of $2,100 and a maximum deductible of $615. The Medicare Prescription Payment Plan is also available to spread drug costs across the year.
