Healthcare enrollment errors can be costly. Watch out for these common pitfalls.
- ×Missing the Medicare enrollment window — this can result in permanent penalties
- ×Not checking Medicaid eligibility because you assume you won't qualify
- ×Missing Open Enrollment for Marketplace plans — you may have to wait until next year
- ×Not reporting income changes — this can affect your premium tax credits
- ×Choosing the cheapest plan without considering total costs (deductibles, copays)
- ×Not applying for Extra Help if you're on Medicare with limited income
- ×Assuming automatic enrollment when it doesn't apply
- ×Delaying coverage until illness worsens — preventive care is usually free
How These Programs Work Together
Healthcare programs often overlap. Understanding these interactions can help you maximize your coverage.
Medicare + Medicaid
"Dual eligibility" — if you qualify for both, Medicaid can cover Medicare premiums, deductibles, and services Medicare doesn't cover.
VA Healthcare + Other Insurance
Veterans can use VA care alongside private insurance or Medicare. VA care may reduce costs or cover gaps.
Marketplace Subsidies + Income Changes
Premium tax credits are based on estimated income. If income changes, report it — or you may owe money at tax time.
SSDI + Medicare Timing
Medicare coverage begins 24 months after SSDI payments start. Plan for the gap with Medicaid, COBRA, or Marketplace coverage.
Eligibility Changes Mid-Year
Losing a job, having a baby, or moving can trigger a Special Enrollment Period. Don't assume you have to wait for Open Enrollment.

Detailed information about each major healthcare program, including eligibility, application steps, and important tips.
Medicare
Medicare is federal health insurance for people 65 and older, certain younger people with disabilities, and people with End-Stage Renal Disease. It covers hospital stays, doctor visits, and prescriptions.
Who this really helps
People 65+, those on SSDI for 24+ months, and people with ESRD or ALS

- You have ALS (Lou Gehrig's disease) or End-Stage Renal Disease
- You want coverage for hospital stays, doctor visits, and prescriptions
How to Apply

- 2If not, apply at SSA.gov or visit your local Social Security office
- 3Choose your Medicare coverage (Original Medicare or Medicare Advantage)
- 4Consider whether you need Part D (prescription drug coverage)
- 5Consider supplemental coverage (Medigap) for out-of-pocket costs

Medicaid
Medicaid offers free or low-cost healthcare to people with limited income. Coverage includes doctor visits, hospital stays, prescriptions, and long-term care services.
Who this really helps
Low-income individuals and families, pregnant women, people with disabilities
What people often miss
Income limits vary widely by state. Many who assume they won't qualify actually do.
This may help if...
- Your income is below your state's Medicaid limit
- You have children and limited income
- You are pregnant
- You are 65+ or have a disability and have limited income
How to Apply
- 1Apply through your state's Medicaid agency or Healthcare.gov

- Children may qualify even if parents don't (through CHIP)
- Medicaid can cover long-term care that Medicare doesn't
- You can have both Medicare and Medicaid ('dual eligible')
CHIP (Children's Health Insurance Program)
CHIP provides low-cost health coverage for children in families who earn too much for Medicaid but still need help affording insurance. Coverage includes routine checkups, immunizations, and dental.

Marketplace Health Plans (ACA)
The Health Insurance Marketplace offers private insurance plans with financial help based on income. Premium tax credits and cost-sharing reductions can significantly lower your costs.
Who this really helps
Self-employed, between jobs, or employer coverage is unaffordable

Frequently Asked Questions
What's the difference between Medicare and Medicaid?
Medicare is federal insurance mainly for people 65+ (and some disabled individuals). Medicaid is a joint federal-state program for people with limited income. You can have both ('dual eligible') if you qualify for each.
How much does Marketplace insurance cost?
With premium tax credits, Marketplace plans can cost $0-100/month for many people. Your actual cost depends on income, household size, and the plan you choose. Use Healthcare.gov to see your personalized costs.
Can I get health insurance if I have a pre-existing condition?
Yes! Under the ACA, insurance companies cannot deny coverage or charge more because of pre-existing conditions. This applies to Marketplace plans, Medicaid, Medicare, and employer plans.
What if I can't afford any health insurance?
Check if you qualify for Medicaid (income-based) or premium tax credits on the Marketplace. Many people who think they can't afford insurance are surprised by how much help is available.
