If the coverage available through your employer feels unaffordable, you can shop around online to see what's available. You may be able to find an individual market policy that will provide you with the coverage you need but is less expensive than the premium you pay at work. This is unlikely to be the case if your plan only covers yourself, since your employer is likely subsidizing a good chunk of the total premiums for the plan offered through your job. But some employer-sponsored plans require the employee to cover the full cost of adding family members, so it's possible that your family members could get a better deal with a separate policy.
A good place to start is HealthCare.gov. This is the health insurance exchange created by the The Patient Protection and Affordable Care Act, and is a one-stop shop for private individual market health insurance plans (note that the exchange itself is run by the government, but the health plans for sale in the exchange are all private, from the health insurance companies with which you're already familiar). People in 39 states use HealthCare.gov to enroll in individual market plans. The other 11 states and the District of Columbia have state-run exchanges, and you'll be directed to their sites from HealthCare.gov when you select your state.
Public health insurance is provided or subsidized in some way by the federal government. Medicare, Veteran benefits, and insurance provided to federal employees are all examples of public health insurance. Private health insurance, on the other hand, is provided by private companies. The CDC estimated that in 2017, 65 percent of Americans under age 65 were covered by private insurance.
According to a Kaiser Family Foundation analysis, in 2018, the average American worker with employer-sponsored health insurance contributed $1,186 for a single employee health plan and $5,547 for a family health plan. Since this is an average, some employees may be paying much more (employers paid the bulk of the total premiums, which averaged $6,896 for single employees and $19,616 for family coverage).
How do the benefits differ? What would you owe in out-of-pocket costs if you were to be injured or get seriously ill? How does that compare with your out-of-pocket exposure on the employer-sponsored plan? Are your doctors in the network of the individual plan? You'll want to carefully consider all of these things before switching, and keep in mind that you won't be able to rejoin your employer's plan until the next open enrollment window offered by your employer.
Individual and family health insurance plans can help cover expenses in the case of serious medical emergencies, and help you and your family stay on top of preventative health-care services. Having health insurance coverage can save you money on doctor's visits, prescriptions drugs, preventative care and other health-care services. Typical health insurance plans for individuals include costs such as a monthly premium, annual deductible, copayments, and coinsurance.
