There’s no federal penalty for being uninsured, but the financial risk is enormous. A single ER visit costs $2,200-$3,500, a hospital stay can exceed $50,000, and you pay full price without the discounts insurers negotiate.

The Bottom Line

While there’s no federal penalty for being uninsured, the financial risk is the real penalty. A single medical emergency can cost tens of thousands of dollars and lead to medical debt or bankruptcy. Check if you qualify for Medicaid, ACA subsidies (many people qualify for $0 premium plans), or a qualifying life event that opens special enrollment. Health insurance is the single most important financial protection you can have.
