Why Health Insurance Matters
Health Insurance provides critical financial protection against risks that could otherwise be financially devastating. Without adequate coverage, a single unexpected event — whether an accident, property loss, or liability claim — can result in financial hardship that takes years to recover from. The right policy provides genuine peace of mind knowing that you, your family, and your assets are protected when you need it most.
Beyond personal financial protection, most types of insurance are either legally required or mandated by lenders. Driving without auto insurance is illegal in almost every state. Mortgage lenders require homeowners insurance as a condition of the loan. Employers in most states are legally required to carry workers compensation coverage. Understanding your legal requirements ensures you remain compliant while also being genuinely protected.
The key is finding the right balance between adequate protection and competitive pricing. Underinsuring to save on premiums is one of the most common and costly mistakes insurance consumers make — the difference between having the right coverage and being underinsured is only apparent when you actually need to file a claim.

When You Can Enroll
ACA marketplace open enrollment typically runs November 1 through January 15 each year (some state-run exchanges extend the deadline slightly). This is the main window to enroll in or change individual marketplace coverage for the upcoming year.
Special Enrollment Periods
Outside open enrollment, you can only enroll if a qualifying life event triggers a Special Enrollment Period (usually a 60-day window):
- Losing other health coverage (job loss, aging off a parent's plan, COBRA ending)
- Marriage or divorce
- Having or adopting a child
- Moving to a new coverage area
- Changes in income affecting subsidy eligibility
Employer Plan Enrollment
Employer-sponsored plans have their own annual open enrollment period, set by the employer rather than the federal marketplace calendar. New hires typically get a separate enrollment window (often 30 days) when starting a job.
Medicaid and CHIP
Unlike marketplace plans, Medicaid and CHIP have no enrollment period restriction — you can apply and enroll at any time of year if you're eligible based on income.
Frequently Asked Questions
