She Spent $482,000 on an Arizona Winter Home and Planned to Stay Seven Months. Her Medicare Advantage Plan Could Still Cut Her Off

A seven-month stay in Arizona may seem harmless, but for some Medicare Advantage members, the clock starts ticking the moment they leave home. Stay away a month too long, and the plan they paid into all year can disappear.

Picture a retiree who has just bought a $482,000 winter home in Arizona. She plans to spend seven months there before heading back north. Her main home, her doctors and her Medicare Advantage PPO plan are all based up north, and the plan does cover out-of-network care. That flexibility makes her think she is protected.

But owning two homes does not necessarily mean she can keep the same coverage. Medicare Advantage has separate rules for permanent relocations and for long trips away from the plan’s service area. Unless her plan includes a qualifying traveler benefit, seven straight months in Arizona could jeopardize her coverage before she ever returns home. People with Original Medicare do not face that same six-month limit and can see any provider anywhere in the country that accepts Medicare.

Medicare Advantage Has a Service-Area Clock

Every Medicare Advantage plan operates within a specific service area, usually made up of certain counties. Under federal rules, a plan generally must disenroll a member who remains outside that area for more than six consecutive months, even if the person has not moved permanently.

That is the problem. She may still think of the northern house as home and yet lose her plan simply because she stayed away too long. Without an exception, a seven-month winter season can put her coverage at risk before she boards her return flight.

Some Plans Give Snowbirds More Time

A visitor or traveler benefit can extend that time. Some plans let members remain elsewhere in the United States for as long as 12 consecutive months, while others set a shorter limit. If her plan allows the full year, disenrollment would begin on the first day of the 13th month. She needs to know the deadline before setting her return date.

Whether a plan offers that benefit is up to the insurer, and some plans limit it to specific parts of the country. For example, a plan might cover winter visitors in Florida but not in Arizona. A PPO’s out-of-network coverage is a separate issue: paying claims outside the network does not stop the service-area clock. Her Evidence of Coverage, the long booklet plans send each fall, should spell out whether a visitor or traveler benefit exists and where it applies. She should read it before booking the season.

Losing the Plan Opens a New Election Window

If the plan disenrolls her for being out of area, she gains a special election period to choose new coverage, such as another Advantage plan or Original Medicare with a standalone Part D drug plan. If she misses that window, Medicare generally treats her as having chosen Original Medicare, which could leave her without prescription drug coverage until she enrolls in Part D.

Original Medicare works in Arizona and back home with any provider who accepts Medicare, but the costs can add up. In 2026, she would face a $283 Part B deductible, a $1,736 Part A hospital deductible per benefit period, and hospital coinsurance of $434 per day for days 61 through 90, with no yearly out-of-pocket cap. A Medigap policy may cover many of those charges, depending on the plan, but it does not automatically pay every deductible or copayment.

She should also find out whether losing her Advantage plan gives her a protected chance to buy Medigap without medical underwriting. Moving out of a plan’s service area can trigger that right. For an extended winter stay, she should ask her State Health Insurance Assistance Program to review the disenrollment notice and explain which protections and deadlines apply.

Count the Months Before Crossing State Lines

1. Before leaving, contact the plan. Tell the plan the dates she will be away and ask two questions: Does it offer a visitor or traveler benefit, and does that benefit include Arizona?
2. Confirm providers in both places. Identify primary care, urgent care and a pharmacy in Arizona that the plan will cover, and make sure her doctors back home remain in network when she returns.
3. Match the calendar to the rules. If there is no traveler benefit, keep the trip to six consecutive months or less. If there is a benefit, return within the period the plan allows. Get that deadline in writing.

She should also keep an eye on the mail. Once the plan knows she is away, the notice usually arrives within the first 10 calendar days of month six, or during the last permitted month under a traveler benefit. If the plan learns about the trip after she has already stayed too long, a different notice deadline applies. She should call as soon as a letter arrives, but silence from the plan does not mean she can stay longer.

Open Enrollment Is the Moment to Fix This

Medicare’s annual open enrollment period runs through December 7, with changes taking effect January 1. A snowbird comparing plans for the next year should put the visitor or traveler benefit on the checklist alongside premiums, drug coverage and provider networks. A lower premium can quickly lose its appeal if the plan cannot keep her covered through the winter.

She bought the Arizona house for the freedom to stay longer. Before settling in for seven months, she needs to know whether her Medicare plan can stay with her.
