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.
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.
