Why Dual Eligibility Matters, Explained Simply
Dual Eligibility: what it is, why it matters, and what published guidance actually asks of you.
Dual-eligible people often qualify for extra help with premiums and drug costs, but the two programs' rules can be confusing.
Key takeaways
- Who pays first: Medicare pays first; Medicaid pays after other coverage
- Drug costs: dual-eligible people automatically qualify for Extra Help
- Most useful single change: Show both your Medicare and Medicaid cards at every visit.
- Commonest mistake: Paying a bill for Medicare cost-sharing if you are in the QMB program; tell the provider instead.
- See a doctor if any of the signs under "When to speak to a doctor" below apply to you.
The short answer
Having both Medicare and Medicaid, which together can cover most health costs for people with limited income.
Where it fits
This is part of Medicare And Medicaid. The published position is set out below, along with what it means day to day.
The numbers, in one place
| Measure | Figure |
|---|---|
| Who pays first | Medicare pays first; Medicaid pays after other coverage |
| Drug costs | dual-eligible people automatically qualify for Extra Help |
| Medicare Savings Programs | state programs that can help pay Medicare premiums and, for some, deductibles and coinsurance |
| QMB program | providers are not allowed to bill people in the Qualified Medicare Beneficiary program for Medicare cost-sharing |
| Special plans | Dual Eligible Special Needs Plans coordinate Medicare and Medicaid benefits |
What that means in practice
What that looks like in practice:
- Show both your Medicare and Medicaid cards at every visit
- Apply for a Medicare Savings Program through your state Medicaid agency
- Ask your State Health Insurance Assistance Program (SHIP) whether a special needs plan suits you
- Keep renewal paperwork up to date for both programs
What gets people into trouble
What to watch out for:
- Paying a bill for Medicare cost-sharing if you are in the QMB program; tell the provider instead
- Assuming you must stay in a plan that is not working for you; plan change rules differ for dual-eligible people
- Ignoring Medicaid renewal notices
