Switching Medigap in Fort Collins: when you sail through, and when insurers can ask questions

FORT COLLINS, Colo. — You picked a Medicare Supplement (Medigap) policy a few years ago, and now you're wondering if you can switch to a different one. Maybe your premium went up, maybe a neighbor mentioned another letter plan, or maybe your health has changed and you want stronger coverage. The honest answer is: sometimes you can switch easily, and sometimes the new insurer can look at your health history first. Knowing which situation you're in — before you apply — is the key to not getting stuck.

Start with the one window everyone gets

When you first enroll in Medicare Part B at age 65 or older, a six-month Medigap Open Enrollment Period begins. During that window, you can buy any Medigap policy sold in your state, and the insurer cannot turn you down or charge you more because of your health. This window happens once, and it does not automatically reopen if you switch later.

That's why so much of the "can I switch?" question comes down to what happens after that first six months.

What "medical underwriting" really means

Outside of a protected window, a Medigap insurer in most states — including Colorado — can ask health questions when you apply to switch. That process is called medical underwriting. Based on your answers, the insurer can:

• Approve you at their standard rate,
• Approve you at a higher rate,
• Add a waiting period for pre-existing conditions, or
• Decline your application.

Underwriting isn't a trick or a punishment; it's how private insurers price policies when you're applying outside a guaranteed window. But it's the reason people are told, again and again: don't cancel your current Medigap policy until the new one is in force.

Federal guaranteed-issue rights

Federal law gives you "guaranteed-issue" rights in specific situations. When one of these applies, insurers must sell you certain Medigap policies, cannot use your health to deny you, and cannot charge you more because of pre-existing conditions.

Common examples include:

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

These rights usually come with a 63-day deadline from when your other coverage ends, so timing matters. You can read the full list on Medicare.gov under "Medigap" and "guaranteed issue rights."

State rules some states add

Beyond federal rules, some states add their own extra protections for switching Medigap. You may have heard about:

• Birthday rules — a set number of days around your birthday each year to switch to an equal or lesser Medigap plan without underwriting.
• Anniversary rules — a similar window tied to the anniversary of your policy.
• Continuous or year-round open enrollment — states where you can change Medigap plans anytime without health questions.

Whether any of these apply in Colorado — and exactly how they work — is something to verify directly, because state rules change and the fine print controls whether a specific switch qualifies. Before you apply anywhere, call Colorado's State Health Insurance Assistance Program (SHIP), known here as the Senior Health Insurance Assistance Program, or the Colorado Division of Insurance. Ask them, in plain terms: "For my situation, can I switch Medigap plans without medical underwriting?"

Fort Collins is in Larimer County, and the same statewide Medigap rules that apply in Denver or Grand Junction apply here — this isn't a city-level decision.

Common mistakes to avoid

A few patterns trip people up every year:

• Canceling too soon. Don't drop your current policy until the new insurer confirms your coverage start date in writing.
• Assuming all Plan G (or Plan N, or Plan F) policies are identical in price. The benefits inside a lettered plan are standardized by federal rule, but premiums and rate increases vary by insurer.
• Missing the 63-day guaranteed-issue clock after other coverage ends.
• Confusing Medigap with Medicare Advantage. These are different products with different enrollment rules; the Annual Enrollment Period (Oct. 15–Dec. 7) and the Medicare Advantage Open Enrollment Period (Jan. 1–March 31) are Advantage/Part D windows, not Medigap windows.
