What happens to my Medicare if I move to another state?

Based on recent evaluations by organizations like the Commonwealth Fund and health system performance scorecards, Louisiana, Mississippi, and Kentucky rank as the bottom three states overall for Medicare beneficiary outcomes, care access, and affordability.

Bottom-Ranked States for Medicare Performance

• Louisiana: Suffers from high rates of high-risk medication usage, heavy prior authorization hurdles, and severe transportation barriers to care.
• Mississippi: Faces major systemic healthcare access limitations and persistent population health challenges.
• Kentucky: Reports some of the highest rates of preventable hospitalizations and excessive administrative hurdles in the region.

Key Factors Impacting Plan Quality

• Prior Authorization: Southeastern states often experience heavier prior authorization restrictions and treatment delays.
• High-Risk Medications: Inappropriate or high-risk drug prescribing rates are most prevalent in states like Louisiana, Florida, Alabama, Arkansas, and West Virginia.
• Rural Deserts: Rural states (such as Montana or parts of Wyoming) deal with sparse provider networks and fewer plan options, creating "Medicare Advantage deserts".
• Out-of-Pocket Costs: States like Maryland and New Jersey record higher average maximum out-of-pocket limits compared to the national average.

Because Medicare Advantage plans operate at the local county or zip-code level rather than statewide, plan quality and network strength can vary widely even within the same state. You can compare specific local options using the Official Medicare Plan Finder.

Your Medicare coverage rules depend on which parts of Medicare you have when you move within the United States.

Original Medicare (Parts A and B)

• No changes: Original Medicare does not change when you move to a new state or county.
• Provider access: You can see any doctor or go to any hospital in the country as long as they accept Medicare.
• Action required: You must update your address with the Social Security Administration so your billing and notices go to the correct place.

Medicare Advantage (Part C) and Part D (Prescription Drug Plans)

• Geographic rules: These private plans are tied to specific local service areas and counties.
• Moving outside the service area: If you move out of your plan's coverage zone, you lose your current plan and must choose a new one or return to Original Medicare.
• Special Enrollment Period (SEP): Moving gives you a special 2-month window to change plans without waiting for the annual open enrollment.
  • If you notify your plan before you move, your SEP starts the month before the move and lasts for 2 full months after.
  • If you notify them after the move, your SEP starts the month you report the move and lasts for the following 2 months.

Medigap (Medicare Supplement Insurance)

• Nationwide coverage: Medigap plans travel with you anywhere in the U.S.
• Price changes: Your monthly premium may change based on the zip code of your new location.
• Guaranteed Issue Rights: Moving out of a Medicare Advantage plan's service area often gives you a right to buy a Medigap policy without a health screening (medical underwriting).

The biggest mistake people make with Medicare is missing enrollment windows, which can lead to permanent financial penalties and coverage gaps.

Timing and Enrollment Mistakes

• Missing Deadlines: Failing to sign up during your Initial Enrollment Period (IEP) around age 65 triggers lifelong financial penalties for Part B and Part D.
• Misjudging Work Coverage: Assuming you can delay enrollment while working past 65 without checking if your employer plan is "creditable coverage" (plans with fewer than 20 employees often require Medicare to go first).
• Missing the Medigap Window: Waiting past your 6-month Medigap Open Enrollment Period (which starts when you turn 65 and enroll in Part B) means you may have to pass medical underwriting to get a supplemental plan.

Plan Choice and Cost Mistakes

• Focusing Only on Premiums: Choosing a plan with a low or $0 monthly premium without checking deductibles, copays, or maximum out-of-pocket costs.
• Ignoring Annual Changes: Not reviewing your plan’s Annual Notice of Change (ANOC) or skipping the Annual Enrollment Period, which leads to surprise costs as drug formularies and doctor networks shift yearly.
• Assuming Doctors are In-Network: Failing to verify if your preferred physicians and hospitals accept your specific Medicare Advantage or Part D network.
• Thinking Medicare is Free: Forgetting that Original Medicare has monthly premiums, deductibles, and coinsurance, and does not cover routine dental, vision, or hearing care.

Vermont, Utah, and Minnesota offer the best overall Medicare benefits and beneficiary experiences according to the Commonwealth Fund Scorecard on Medicare Performance.

Medicare is a federal program, so baseline rules stay the same across the U.S.. However, access, extra plan benefits, costs, and quality vary heavily by state due to local health infrastructure and state regulations.

Original Medicare (Parts A and B) does not cover several major healthcare needs, most notably routine dental care, eye exams and glasses, hearing aids, long-term custodial care, care outside the U.S., and cosmetic surgery.

Key Uncovered Services

• Routine Dental Care: Original Medicare excludes routine cleanings, fillings, tooth extractions, root canals, and dentures.

• Hearing Aids: Routine hearing exams, fittings, and hearing aids are completely excluded from standard coverage.
• Long-Term Care: Medicare pays for short-term skilled nursing, but it does not cover ongoing custodial care (help with daily activities like bathing, dressing, or eating) in a nursing home or at home.
• Care Outside the U.S.: Medical treatment received while traveling or living abroad is generally not covered.
• Cosmetic Surgery: Elective procedures meant to alter appearance rather than treat a specific illness or injury are excluded.
