Learn How Medicare and Medicaid Work When Moving

Understanding Medicare and Medicaid: Key Differences

Medicare and Medicaid are two separate government health insurance programs, but many people confuse them because of their similar names. Understanding how each program works is important, especially when you're planning to move to a new state or region. Medicare is a federal program run by the Centers for Medicare & Medicaid Services (CMS) that serves people age 65 and older, regardless of income. It also covers some younger people with disabilities and those with end-stage renal disease. Medicaid, by contrast, is jointly funded by federal and state governments, and each state runs its own program. This means Medicaid rules and coverage vary significantly from state to state.

The funding sources for these programs differ as well. Medicare is funded primarily through payroll taxes—employees and employers each contribute 1.45% of wages to Medicare. When you turn 65, you become part of the Medicare system if you've worked and paid taxes for at least 10 years (or if you're a spouse or dependent of someone who has). Medicaid is funded through general tax revenue and is designed primarily for low-income individuals and families. Because Medicaid is state-operated, the income limits, covered services, and enrollment processes can vary dramatically. For example, a family with the same income might be within Medicaid's scope in one state but not in another.

These differences matter significantly when you move. Your Medicare coverage generally follows you across state lines without changes—your Part A and Part B coverage remain the same. However, Medicaid is state-specific. If you're receiving Medicaid in your current state and move to another state, your coverage will end, and you'll need to work with the new state's Medicaid program. This can create gaps in coverage if you don't plan ahead. Understanding these distinctions helps you prepare for a move and know what to expect during the transition period.

Practical Takeaway: Before moving, learn whether you rely on Medicare, Medicaid, or both. Medicare moves with you; Medicaid does not. Research your new state's Medicaid program separately to understand what coverage might be available after your move.

How Medicare Works When You Relocate

Medicare coverage is national and portable, which means you can move to any state and keep your Medicare benefits. This is one of the biggest advantages of Medicare—your Part A (hospital insurance) and Part B (medical insurance) follow you automatically. If you have a Medicare Advantage plan (Part C) or prescription drug coverage (Part D), these may also continue, though you should verify the details with your insurance provider. Most people don't need to do anything to maintain their Medicare when they move, but there are important details to understand about coverage networks and plan changes.

When you move, the hospitals, doctors, and healthcare facilities that accept Medicare in your new location may be different from those in your previous state. While Medicare is accepted nationwide at participating providers, not all providers accept Medicare, and networks can vary. If you have a Medicare Advantage plan, which operates more like traditional insurance with specific provider networks, moving to a new area might mean your current plan no longer serves your location. In this case, you may want to switch plans during the Annual Enrollment Period (October 15 through December 7 each year). Medicare Advantage plans change their service areas annually, so a plan available where you used to live might not be available in your new state.

If you move during the year and your Medicare Advantage plan no longer serves your new address, you have options. You can disenroll from your current plan and switch to Original Medicare (Part A and Part B) outside the normal enrollment period. You also have 60 days from receiving notice that your plan is leaving your area to switch to a different Medicare Advantage plan or to Original Medicare. For prescription drug coverage (Part D), if your current plan doesn't serve your new location, you can switch to a different Part D plan during a special enrollment period. It's important to contact your current insurance provider before or shortly after moving to confirm your coverage continues and to discuss your options in the new area.

Practical Takeaway: Your basic Medicare coverage (Part A and B) travels with you across state lines. However, review your Medicare Advantage or Part D plans to confirm they serve your new location. Contact your insurance company within the first month after moving to update your address and verify continued coverage.

Medicaid and State-to-State Transitions

Medicaid is where moving becomes more complicated because each state administers its own program with different rules. Your Medicaid coverage from your current state will not automatically transfer to your new state. When you move, your existing Medicaid will end in your current state, and you'll need to work with the new state's Medicaid program to understand what options may be available. The timeline for this transition matters—ideally, you should contact your new state's Medicaid program before you move or within the first few weeks after arrival. States have different processing times, so there could be a gap in coverage if you wait too long.

Each state sets its own Medicaid income limits, and these vary considerably. As of 2024, some states have adopted Medicaid expansion under the Affordable Care Act, which means they cover more people at higher income levels. Other states have not expanded Medicaid, so coverage is more limited. For example, a single adult with an annual income of $18,000 might have Medicaid coverage in a Medicaid expansion state but not in a non-expansion state. The covered services also differ—some states cover more dental, vision, or mental health services than others. This means the scope of your coverage may change when you move, even if you remain within the Medicaid program.

To navigate this transition, start by contacting your current state's Medicaid office to notify them of your move. You should request that they formally close your case and provide documentation of your current coverage. Then contact the Medicaid office in your new state—you can find this through Medicaid.gov or by searching for "[Your New State] Medicaid." Many states now have online portals or phone lines to help people learn about Medicaid. Be prepared to provide information about your household income, family size, and citizenship status. Some states may allow you to transfer certain information from your previous state, which can speed up the process. During the transition, consider whether you have other health coverage options, such as coverage through an employer or a family member's plan, to bridge any gaps.

Practical Takeaway: Medicaid doesn't transfer between states. Before moving, contact your current state's Medicaid program to close your case. Then contact your new state's Medicaid program to learn about the income limits and covered services in that state, and understand the process for any potential coverage.

Special Enrollment Periods and Coverage Changes

A move to a new state or different address within a state typically qualifies you for a special enrollment period (SEP) with both Medicare and Medicaid. A special enrollment period is a limited time window outside the standard annual enrollment periods when you can make changes to your coverage due to a life event. Moving is considered a qualifying life event under federal rules. For Medicare, if you move and your Medicare Advantage plan or Part D prescription drug plan no longer serves your new address, you have 60 days from the date you receive notice that the plan is leaving your service area to switch coverage. Additionally, if you move out of your current plan's service area, you may have up to 60 days to make changes.

With Original Medicare (Part A and Part B), you don't need to make changes if you move—your coverage continues nationwide. However, if you're on a Medicare Advantage plan and want to switch to Original Medicare due to moving, you can do so during the Medicare Advantage Open Enrollment Period (January 1 through March 31) without waiting, or you can make a change during a special enrollment period triggered by your move. For Part D prescription drug coverage, if you move to an area where your current plan doesn't operate, you have 60 days to switch to a plan that does serve your new location.

For Medicaid, the special enrollment period rules vary by state. Generally, moving is considered a change in circumstances that may affect your coverage. When you report your move to the Medicaid office, they will reassess your potential coverage based on your new state's rules. Some states process these changes quickly (within 10 to 30 days), while others may take longer. It's important to document the date you moved and the date you notified Medicaid, as this establishes when the transition should begin. If there's a gap in coverage, some states may allow retroactive coverage back to your move date if you apply within 30
