If you lose your job, you should be able to maintain your health insurance coverage -- but it will cost you. The easiest and often the least expensive way to get health insurance if you are out of work is through a spouse. If your spouse has group benefits on the job, have him or her add you to that plan. Such group plans can't exclude people with preexisting conditions, and they are less expensive than other options because the employer is picking up the lion's share of the premium.

If that's not an option, you may be able to get coverage under COBRA. The federal Consolidated Omnibus Budget Reconciliation Act requires employers of 20 or more people to extend coverage for 18 months to workers who lose their jobs. This is also available to people whose jobs are reduced to part-time status. The catch is that you must pay for this coverage yourself at a time when you no longer have a paycheck coming in. And it's not cheap. You must pay the entire premium, including the part your employer was paying, plus 2%.

Monthly premiums for COBRA and Cal-COBRA coverage vary depending on age, type of plan (health maintenance organization or preferred provider organization) and the size of your former employer. For example, HMO coverage for a 25-year-old who had worked for a small employer would cost about $250 a month, while the premium for PPO coverage for a 55-year-old could exceed $1,000 a month. Larger employers are able to drive better bargains with insurers, so premiums for employees leaving those companies tend to be a bit less and may not vary by age.

It’s important to note that COBRA coverage cannot be denied because of a preexisting condition, and it often has richer benefits than what individuals could buy on their own. But young and healthy consumers may find cheaper coverage with an individual policy.

And if you haven't done so already, by all means file for unemployment.
