If leaving a job means losing your health insurance, you can get coverage through a government health care exchange or another insurer, or you can stick with your employer's plan for up to 18 months. Getty Images By Kimberly Lankford, Contributing Editor March 15, 2018 QI'm thinking about leaving my job and starting my own business, but I'll lose my health insurance from work. Can I sign up for coverage through HealthCare.gov now, or do I have to wait until open enrollment?AYou usually need to wait until open enrollment to buy individual health insurance, but you can get coverage anytime during the year if you're eligible for a "special enrollment period." To qualify, you must have experienced one of several life changes, which include leaving your job and losing your employer health coverage; moving to a new zip code; getting married; having a baby or adopting a child; or losing health insurance because you got divorced or legally separated. If you qualify for a special enrollment period, you usually have up to 60 days following the event to enroll in a new health insurance plan. See Healthcare.gov for more information about special enrollment periods.

Depending on your state, either you'll be able to buy individual health insurance at the site or you'll find a link to your state's health insurance marketplace. If your income is less than 400% of the federal poverty level ($48,240 for singles, $64,960 for couples or $98,400 for a family of four in 2018), then you'll qualify for a subsidy to help pay the premiums of a policy you purchase through HealthCare.gov or your state's health insurance marketplace. Use the tool at HealthCare.gov to see if you qualify for a subsidy. If your income is higher than the cut-off point, you can still buy a policy through the marketplace, but you won't receive a subsidy. You may also want to compare the costs and coverage of policies offered through a health care exchange to policies that are being sold outside of the marketplace, such as directly from an insurer, through an agent or at a website such as eHealthInsurance.com. Your state insurance department may also have information about health insurance available in your state. See www.naic.org/map for links. Advertisement Another option is to continue your current coverage under COBRA. That's the federal law that allows people to stay on their employer's plan for up to 18 months after leaving a job. COBRA coverage tends to cost more than individual insurance because you have to pay both the employer's and the employee's share of the cost. You would, however, have the same provider network and cost-sharing arrangements that you have now. Ask your employer about your options. People who want to change health insurance plans midyear and don't qualify for a special enrollment period need to wait until the next open-enrollment period to buy a new policy. Open enrollment for coverage starting in 2018 ran from November 1 to December 15, 2017. No open-enrollment period has been set for choosing 2019 coverage, although it may be similar to last year's. Some states also have longer enrollment periods. SEE ALSO: 50 Ways to Save on Health Care Got a question? Ask Kim at firstname.lastname@example.org.
