Moving a parent to Houston this winter? Look at their Medicare coverage before December 7. That's the last day of open enrollment, and a Medicare Advantage or drug plan from another area may not cover Houston doctors at all. A move also opens a special enrollment window, so the right timing depends on when they arrive.
Open enrollment started October 15 and runs through December 7. Changes take effect January 1, 2027. This year has more moving parts than usual. According to the Associated Press, the Part D out-of-pocket cap rises to $2,400 in 2027, from $2,100, and some Medicare Advantage plans are leaving certain areas or trimming benefits. If a parent is also changing cities, it's easy for a plan that worked fine at home to stop working here.
Does Medicare Advantage work if a parent moves to another city?
Usually not for long. Medicare Advantage plans are built around a local service area and a local network, so a plan from Dallas, Louisiana or Ohio won't cover a Houston primary care doctor the way it did back home. Original Medicare works anywhere in the country that accepts it, and so does a Medigap supplement, though the premium can change with the new address.
Short answer: check the plan type first.
When can they switch plans after moving?
Medicare gives people who move out of their plan's area a special enrollment period. Per CMS, if they tell the plan before the move, the window opens the month before they move and runs for two full months after. If they tell the plan after moving, it starts the month they tell it and runs two more full months. There's a separate window for anyone moving into or out of a nursing home or rehab facility, and it lasts as long as they live there plus two months after.
| If the move happens… | What to do |
|---|---|
| Before December 7 | Update the address with Social Security, then pick a Houston-area plan during open enrollment |
| In December | Choose carefully in open enrollment, then use the moving window if the plan doesn't cover the new area |
| Early 2027 | Keep this year's choice simple, then switch within the moving window after the move |
What to check before choosing a Houston plan
I was a nurse before I was a REALTOR®, and the coverage gap I'd worry about most is continuity of care: the specialist, the prescriptions and the hospital. Make a list of every doctor your parent sees, every medication with its dose, and which hospital system they'd want if something happened. Then check each plan's network against that list. Houston's big systems, including Memorial Hermann, Houston Methodist, HCA Houston Healthcare, Baylor St. Luke's and Kelsey-Seybold, don't all contract with every plan, and the closest hospital to a new home isn't always in network. Call the doctor's office to confirm, too. The online directories aren't always current.

Where the house fits in
Coverage can shape where a parent should live. A home 15 minutes from their cardiologist's in-network hospital is worth more than a bigger one across town. If you're still choosing, my guides on helping a parent move closer and aging in place versus moving go through the housing side, and my senior transitions page explains how I help families plan the move.
Frequently asked questions
When does Medicare open enrollment end? Open enrollment runs October 15 through December 7, and changes take effect January 1, 2027.
Can my parent keep their Medicare Advantage plan if they move to Houston? Usually not for long. Medicare Advantage plans cover a specific service area and network, so a plan from another region generally won't work in Houston. Moving out of the service area opens a special enrollment period to switch.
How long is the special enrollment period after moving? If your parent tells the plan before moving, it starts the month before the move and lasts two full months after. If they tell the plan after moving, it starts that month and lasts two more full months.
Does Original Medicare work in a new state? Yes. Original Medicare works with providers nationwide who accept it, and a Medigap supplement moves with your parent, though the premium can change with the new address.
