It's that time of year: Open enrollment for workplace medical and health benefits begins soon for millions of workers across the country. It is an annual tradition of reading the email from HR, scanning to the part that lists the premium costs and hoping coverage stays the same or, for those optimistic enough, improves.

To help you think outside the box, here are five tips from my experience in helping clients navigate open enrollment:

1. Give Your Health Insurance a Checkup

Now is a good time to evaluate how you used your medical insurance last year. If your company gives you a choice of providers, you'll want to review whether the deductible level, choice of doctors and cost all still make sense. If you don't use your medical insurance as often as you thought, perhaps a higher-deductible plan can help keep the monthly costs down.

2. Get a Tax Break

If you have a high-deductible plan, ensure you are enrolled in the Health Savings Account (HSA). Otherwise, consider funding a Flexible Spending Account (FSA) if your company offers it.

The rules are different for each — most notably an HSA has higher contribution limits and it allows you to carry over all the money not spent from year to year, while an FSA may allow workers to carry over up to $550, depending on their employer — but they both can help lower your taxable income. For instance, an employee who earns $100,000 salary and contributes $2,650 to an FSA or HSA during the year, is only taxed on $97,350 of income.

Below are the HSA contribution limits. If you're 55 or older at the end of the year, you can put in an extra $1,000 in "catch up" contributions. However, your contribution limit is reduced by the amount of any contributions made by your employer that are excludable from your income, including amounts contributed to your HSA account through a cafeteria plan.

3. Look at Life Insurance Costs

Now is a good time to evaluate the cost of your group term insurance. Many folks seem to take for granted that they are getting the best rate because of a group discount. But that is not always the case.

I recently ran quotes for two individuals and found I could save them a few hundred bucks a year by buying their term insurance outside of the company. Better yet, when you own your life insurance outside of the company, you can lock in the premium cost, say for 10 or 20 years, something you can't do with group life insurance, as the premium can increase year to year. You should review spouse group term insurance vs. buying term insurance through an outside carrier as well.

4. Review Your Employer's Disability Coverage

To the extent you need it, maintain your group short-term and long-term disability coverage, which is often the cheapest coverage you will find. However, group disability usually has limitations, such as a restrictive definition of disability or no portability, or worse no coverage for a partial disability, which is the most common form of a long-term disability.

You may want to see if your company offers supplemental disability in addition to the group, or price out a stand-alone policy with a private company.

5. Think Critically on Accidental Death Coverage

If you always opt in for the Accidental Death and Dismemberment Life Insurance (AD&D), you may want to reconsider. AD&D only covers very specific causes of death – think extreme accidents where you lose an eye or a limb. These are very rare, hence the premium is so cheap. You may want to consider allocating the premiums from the Accidental Death and Dismemberment toward buying more life insurance where the definitions of death are not as restrictive.
