"You need to release any medically relevant information," she says.
Some states provide extra consumer protections related to genetic testing and long-term-care insurance, says Sonia Mateu Suter, a law professor at George Washington University who specializes in genetics and the law. But most follow federal law.
If you get genetic testing after you have a policy, the results can't affect your coverage.
"Once the policy has been underwritten and issued, the insurer doesn't revoke the policy if new medical information comes to light," Theroux says.
Q: Can I switch Medigap insurance companies midway through the year? I found a less expensive policy.
It depends. Under federal law, when people turn 65 and first enroll in Medicare Part B they have a six-month window to sign up for a Medigap plan — a commercial policy that picks up some of the out-of-pocket costs for services that Medicare doesn't cover. (Medicare Part A covers hospitalization, and Medicare Part B covers outpatient services.) During that six-month period, insurers have to accept enrollees, even if they have health problems.
If you're still within that six-month period now and you want to switch plans, go right ahead.
But if you're past the six-month window, under federal law, insurers are required to sell you a plan only in certain circumstances — such as if you lose your retiree coverage or Medicare Advantage plan. If you don't meet the criteria, insurers can decline to cover you or charge you more for preexisting medical conditions.
Many states have provided more robust protections, however. Three states — Connecticut, Massachusetts and New York — have year-round open enrollment and require insurers to offer coverage. And Maine requires a one-month "guaranteed issue" open-enrollment period every year.
Some states guarantee current policyholders a chance to switch Medigap plans at certain points during the year. Other states have additional qualifying events that allow people to switch Medigap plans, according to data from the Kaiser Family Foundation.
"The first thing the person should do is check with her state insurance department to find out her rights related to buying a Medigap plan," says Brandy Bauer, associate director at the Center for Benefits Access at the National Council on Aging. If you decide to go ahead and switch, she says, it is wise to sign up for a new plan before terminating your current policy.
Q: I did not enroll in Medicare Part B when I turned 65 because I already have a regular plan that covers everything. I was told that the insurer would keep paying as usual, but now the company says it will pay only part and that I have to buy Medicare Part B. I didn't want to pay for two policies. Is there anything I can do to avoid that?
From your description, it's hard to know exactly what's going on, but we can make educated guesses. Typically, when people turn 65, it makes sense to sign up for Medicare unless they or their spouse are working and getting health insurance from an employer. For others, at age 65, Medicare typically becomes their primary insurer and any other coverage they have becomes secondary, filling in gaps in Medicare coverage.
If you have an individual policy that you bought on the health insurance exchange, and decide to hang on to it instead of signing up for Medicare, your premiums and other costs could be higher than they would be on Medicare, depending on your income.
But if you're not receiving employee coverage and you don't enroll in Medicare Part B, you could be subject to a permanent late enrollment penalty of 10 percent of the policy's premium for every 12 months that you could have signed up for Part B but didn't.
You could also owe a premium penalty for not signing up for a Part D prescription drug plan. (Most people don't owe any premium for Medicare Part A, so there's no penalty for late sign-up.)
Your best move now may be to call 800-Medicare or visit your local state health insurance assistance program to help sort out your coverage issues, including whether to drop your current coverage and sign up for Medicare Part B and Part D.
