Changing Medigap in Miramar: the underwriting question that decides everything

You picked a Medigap policy when you first went on Medicare, and now, a few years later, you are wondering if you can move to a different one. Maybe your premium has crept up. Maybe a neighbor in Miramar mentioned a plan letter you had not looked at closely. The short answer is yes, you can apply to switch — but whether an insurer has to accept you, and at what price, comes down to one word: underwriting.

That single question shapes almost every part of the switch. Here is how it works, what federal law protects, and what you should check before you sign anything.

What "medical underwriting" actually means

When you first became eligible for Medicare Part B at 65, you had a six-month Medigap open enrollment period. During that window, any Medigap insurer selling in Florida had to sell you a policy at their standard rate, regardless of your health. That is a one-time protection.

After that window closes, the rules change. If you apply for a new Medigap policy later, the insurer can generally ask health questions, review your prescription history, and either approve you, charge you a higher rate, or turn you down. That process is medical underwriting. It is legal in most situations, and it is the main reason people who want to switch sometimes cannot — not because the law forbids the switch, but because the new insurer says no.

Federal guaranteed-issue rights

Federal law carves out specific situations where insurers must sell you certain Medigap policies without underwriting. These are called guaranteed-issue rights. Common examples include:

• Your employer or union coverage that was paying secondary to Medicare is ending.
• You are in a Medicare Advantage plan and it leaves your service area, or you move out of its service area.
• You joined a Medicare Advantage plan when you first turned 65 and want to switch back to Original Medicare within the first 12 months (the "trial right").
• Your Medigap insurance company goes bankrupt or misled you.

In these cases you typically have a 63-day window to apply, and the insurer cannot use your health to deny you or raise your price. The specific Medigap plan letters available under guaranteed issue are limited, and the list depends on when you first became eligible for Medicare. Medicare.gov has the full chart under "Medicare Supplement Insurance."

State rules some states add on top

Federal law is the floor, not the ceiling. A handful of states have added extra protections that let residents switch Medigap plans without underwriting on a regular basis:

• Birthday rules — a window around your birthday each year to switch to an equal or lesser plan with the same insurer or a different one.
• Anniversary rules — a similar window tied to your policy anniversary.
• Continuous or year-round open enrollment — the insurer must accept you at any time.

Florida is not among the states that have historically had a birthday or anniversary rule, but state insurance rules do change, and there are narrower Florida-specific protections worth confirming. Before you assume underwriting will apply to your switch, call SHINE, Florida's State Health Insurance Assistance Program, at 1-800-963-5337, or check with the Florida Office of Insurance Regulation. Advice from a licensed SHINE counselor is free and unbiased.

How to decide whether to try switching

If you are a Miramar resident thinking about a change, walk through these questions before you apply:

1. Do you qualify for a guaranteed-issue right right now? If yes, act inside the 63-day window and you cannot be turned down for the plans you are entitled to. 2. If not, are you in good enough health that underwriting is likely to go smoothly? Insurers vary in what they ask. A licensed agent or SHINE counselor can walk you through the health questions before you formally apply. 3. Have you compared the same plan letter across insurers? A Plan G is a Plan G by federal law — the benefits are standardized. What differs is the premium and the company's rate history. 4. Do not cancel your current Medigap policy until the new one is approved and in force. Most states, including Florida, give you a 30-day "free look" period on the new policy so you can compare before committing.

Medigap is not Medicare Advantage

One more thing worth clearing up, because these get confused constantly. Medigap works alongside Original Medicare and helps pay your share of Part A and Part B costs. Medicare Advantage (Part C) replaces the way Original Medicare pays and is offered by private insurers. Miramar is in Broward County, where a large number of Medicare Advantage plans are sold, and the Annual Enrollment Period from October 15 to December 7 is the main window for Advantage and Part D decisions. Medigap has its own separate rules and is not tied to that calendar.

If you have a Medigap policy, you also need a stand-alone Part D drug plan — and in 2026 Part D has a $2,100 annual out-of-pocket cap and a maximum deductible of $615. Switching Medigap plans does not change your Part D coverage, and switching Part D does not affect your Medigap.
