Under 65 Health Insurance 101

Health insurance before Medicare, explained in plain language

Buying your own coverage, self-employed, between jobs, or offering benefits to your employees? Here's where coverage comes from, what the common terms mean, and the dates that matter for 2027.

The basics

Where coverage comes from

Most people under 65 get health insurance in one of these ways. The right fit depends on your job, your income, your health, and how long you need coverage.

Employer coverage

A group plan through your job or a spouse's job. When it's offered, it's often the most affordable choice because the employer pays part of the premium.

Individual plans

Plans you buy yourself, through the Health Insurance Marketplace (HealthCare.gov) or directly from an insurance company. They must cover pre-existing conditions and essential health benefits. Financial help is only available through the Marketplace.

COBRA

Keeps your former employer's plan after you leave a job, usually for up to 18 months. You typically pay the full premium plus a small fee, so it can be expensive.

Short-term medical

Temporary coverage for a gap, such as between jobs. Premiums are usually lower, but these plans can exclude pre-existing conditions and don't have to cover every essential benefit.

Medicaid

Free or low-cost coverage for people with lower incomes. In Ohio, many adults qualify with household income up to 138% of the federal poverty level.

Coverage for your business

Group health plans for employers, or reimbursing employees for individual coverage through an arrangement called an ICHRA. Good benefits help you attract and keep employees.

Timing matters

Key dates and deadlines

  1. Nov 1, 2026 – Jan 15, 2027

    Open Enrollment for 2027

    The yearly window to buy or change an individual plan. Enroll by December 15 for coverage that starts January 1.

  2. Within 60 days

    Special Enrollment Period

    Losing other coverage, moving, getting married, or having or adopting a baby can open a 60-day window to enroll outside Open Enrollment. You may need to show proof.

  3. Within 60 days

    Electing COBRA

    After leaving a job, you generally have 60 days from your COBRA notice to decide whether to keep your employer plan.

  4. Set by your employer

    Employer open enrollment

    Usually in the fall. It's your yearly chance to join, change, or drop a job-based plan.

  5. Turning 65

    Moving to Medicare

    Your Medicare enrollment window opens 3 months before your 65th birthday month. See our Medicare 101 guide.

Losing coverage? Don't wait. Most Special Enrollment Periods last only 60 days. If you miss the window, you may have to wait until the next Open Enrollment to get an individual plan.
For 2027

What's different next year

100% – 400%

Income range, as a share of the federal poverty level, that can qualify for Marketplace premium tax credits. For one person that's about $15,960 to $63,840. The extra subsidies of recent years have expired, so the 400% cutoff is back.

$4,500 / $9,000

2027 Health Savings Account (HSA) limits for self-only and family coverage, plus $1,000 more if you're 55 or older.

Bronze & catastrophic

Marketplace Bronze and catastrophic plans can now be paired with an HSA, so more people can save pre-tax for medical costs.

Many people will see higher premiums in 2027, and some insurers have changed their plan options. If you were automatically renewed, check that your plan still fits your doctors, prescriptions, and budget.

Extra protection

Filling the gaps

Health plans don't cover everything, and high deductibles can leave you exposed. These add-on policies can help.

  • Dental and vision for checkups, cleanings, glasses, and contacts
  • Hospital indemnity pays cash if you're hospitalized
  • Accident coverage for injuries like sprains, fractures, and ER visits
  • Critical illness pays a lump sum for a diagnosis such as cancer, heart attack, or stroke
  • Life insurance to protect the people who depend on you
