Someone in a support group tells you their state pays a family member to provide care. Someone else says their walker was fully covered. A third says they got a Medigap policy at 58. All three may be telling the truth, and none of it may apply to you.
That is not misinformation. It is federalism. Roughly half of what matters after a Parkinson’s diagnosis in the United States is decided in your state capital, not in Washington — and the half that varies is not obvious from the outside.

Five kinds of rule, and only two of them travel
Before chasing an answer, work out which bucket the question is in. It tells you who decides, and whether anything you read online applies to you.
| Bucket | Examples | Does it vary by state? |
|---|---|---|
| Purely federal | SSDI rules and the substantial gainful activity level, SSI’s federal benefit rate, the Medicare parts and their premiums, IRS medical expense rules, ADA and FMLA | No. Same in all fifty states |
| Federal money, state rules | Medicaid eligibility, HCBS waivers, personal care, Medicare Savings Program administration | Enormously. This is where most of the variation lives |
| Federal floor, states may add | Employment leave and discrimination protections | Yes, upward only. Your state may give more, never less |
| State-regulated private market | Medigap policies, long-term care insurance | Yes. Whether you can buy at all can depend on your address |
| Purely state or local | Disabled parking permits, driver licensing and medical review, property tax relief, state pharmaceutical assistance | Entirely |
Two things follow. First, when someone quotes a dollar figure for SSDI or Medicare, it applies to you. Second, when someone describes what their Medicaid program paid for, assume nothing.
Where the variation actually bites
Four specific places, in rough order of how much money is at stake.
Medicaid home care. A 1915(c) waiver is allowed to depart from the usual Medicaid rules in ways that are invisible unless you know to look. A state may waive statewideness, which “lets States target waivers to areas of the state where the need is greatest” — so a program can exist in some counties and not others. It may waive comparability, offering services “only to certain groups of people who are at risk of institutionalization,” targeted by age or diagnosis. And states “choose the maximum number of people that will be served,” which is what produces waiting lists.
Whether Medicaid is even open to you. Income counting for people who are aged or have a disability follows SSI methodology rather than the ordinary rules, and separately, states may run a medically needy program that lets you qualify by spending down. Thirty-six states and the District of Columbia run spend-down programs. If you live in one of the others, the same income gets a different answer.
Medigap before 65. This one is stark. Federal law generally does not require insurers to sell Medigap policies to people under 65, “however, in some states insurance companies do offer Medigap policies to people under 65.” If you came to Medicare through SSDI, whether you can buy supplemental coverage at all is decided by your state legislature.
Help with drug costs. Beyond federal Extra Help, Medicare points people to state programs: “find out if your state offers help with drug costs.” Some states run pharmaceutical assistance programs; others do not.
The six offices that hold the answers
You do not need to find fifty programs. You need six phone calls, and most people never make more than two of them.
1. Your State Health Insurance Assistance Program (SHIP)
Start here. Every state has one. Medicare describes SHIPs as giving free, personalized health insurance counseling, and — the part that matters — notes they “aren’t connected to any insurance company or health plan.”
What they cover: choosing a plan, reviewing coverage, understanding costs, applying for Extra Help, and filing a complaint or an appeal. They will also walk you through a Medicare appeal at no charge.
Find yours at shiphelp.org.
2. Your state Medicaid agency
The only body that can actually decide your Medicaid eligibility. Federal pages describe the rules; your state applies them. Medicaid.gov keeps a state-by-state contact directory — every state, territory and the District of Columbia, each linking to its own agency’s contact page.
Ask, in one call:
- Which HCBS waivers operate in my county, and is there a waiting list?
- Does this state have a medically needy spend-down?
- Do the financial rules for waiver services differ from regular Medicaid, and do spousal protections apply?
- Does this state allow self-direction, and may a family member be paid?
- What is your estate recovery policy, and what hardship waiver exists?
3. Your state insurance department
The authority on Medigap and on private long-term care insurance. Medicare directs people here twice — once for buying outside the open enrollment period, and once specifically for people under 65: “check with your State Insurance Department about what rights you might have under state law.”
Ask: can I buy a Medigap policy before 65 here, at what price, and do I have any state-law guaranteed issue rights beyond the federal ones?
4. Your state labor department
The Department of Labor’s own instruction on FMLA is to “check with your State Labor Department to determine if you have additional or greater protections under state law.” Several states run paid family and medical leave insurance, and some cover smaller employers than the federal 50-employee threshold.
Ask: is there a paid leave program here, what is the eligibility, and does state leave law cover my employer even though FMLA does not?
5. Your state fair employment practices agency (FEPA)
For discrimination complaints, the EEOC works alongside state and local agencies, which “may have dual-filing agreements with EEOC.” This matters for a deadline, not just a venue — the federal filing window extends from 180 to 300 days where a state or local agency enforces a matching law.
6. Your state vocational rehabilitation agency
If work is in the picture, state VR agencies and Employment Networks provide job support under Ticket to Work. Social Security keeps a service provider directory at choosework.ssa.gov/findhelp, and the same help line reaches WIPA benefits counsellors and PABSS legal advocates in every state and territory: 1-866-968-7842, TTY 1-866-833-2967.
Questions that always have a state-specific answer
Keep this list. When any of these come up, the answer is local and the internet will mislead you.
- Which home care services are covered, and for how many hours
- Whether there is a waiting list, and how long
- Whether a spouse or adult child can be paid to provide care
- Whether a Medigap policy is available to you before 65
- Whether a medically needy spend-down exists
- What the Medicaid estate recovery policy and hardship waiver look like
- Whether there is a state pharmaceutical assistance program
- Disabled parking permits, and the medical certification they require
- Driver licensing and medical review after a neurological diagnosis
- Property tax relief or utility discounts for people with disabilities
- Paid family and medical leave
- What your state’s Medicaid fair hearing deadline is
Two on that list — parking permits and driver licensing — sit with your state motor vehicle agency rather than any health or benefits office, and they are the ones people most often ask the wrong department about.
Making the calls count
If you move states
Nothing about Medicaid travels. A waiver slot, a spend-down arrangement, a self-direction plan and a paid family care arrangement are all creatures of the state you left. Moving means applying again, from the bottom of a new waiting list.
Medicare does travel — but the plan attached to it may not. Original Medicare works with any provider that takes Medicare anywhere in the country; a Medicare Advantage plan has a service area, and moving outside it is one of the events that opens a Special Enrollment Period. Check before the move, not after.
If a move is under consideration for family or cost reasons, the waiver waiting list in the destination state deserves to be part of the arithmetic.
If this applies to you
| Your situation | Which door |
|---|---|
| Any question about Medicare, plans, costs or appeals | Your SHIP, free, at shiphelp.org. Start here by default |
| Home care, personal care, respite, waiting lists | Your state Medicaid agency, via the directory on Medicaid.gov |
| Under 65 and want a Medigap policy | Your state insurance department. This is decided entirely by state law |
| Told your income is too high for Medicaid | Ask your state agency whether it runs a medically needy spend-down — 36 states and DC do |
| Employment leave or a workplace problem | Your state labor department for leave, your state FEPA for discrimination |
| Thinking about work while on benefits | 1-866-968-7842 reaches WIPA, PABSS and the Ticket to Work provider directory |
| Parking permit or driving after diagnosis | Your state motor vehicle agency, not a health agency |
| Someone told you their state does something yours does not | They may be right. Ask which bucket the rule sits in before assuming it applies to you |
| Considering moving state | Medicaid does not transfer. Check the destination’s waiver waiting list before deciding |
