Glossary of Insurance Terms

Hazard - A circumstance that increases the likelihood or probable severity of a loss. For example, the storing of explosives in a home basement is a hazard that increases the probability of an explosion.

Hazardous Activity - Bungee jumping, scuba diving, horse riding and other activities not generally covered by standard insurance policies. For insurers that do provide cover for such activities, it is unlikely they will cover liability and personal accident, which should be provided by the company hosting the activity.

Health Maintenance Organization (HMO) - Prepaid group health insurance plan that entitles members to services of participating physicians, hospitals and clinics. Emphasis is on preventative medicine, and members must use contracted health-care providers.

Health Reimbursement Arrangement - Owners of high-deductible health plans who are not qualified for a health savings account can use an HRA. 

Health Savings Account - Plan that allows you to contribute pre-tax money to be used for qualified medical expenses. HSAs, which are portable, must be linked to a high-deductible health insurance policy. 

Hurricane Deductible - Amount you must pay out-of-pocket before hurricane insurance will kick in. Many insurers in hurricane-prone states are selling homeowners insurance policies with percentage deductibles for storm damage, instead of the traditional dollar deductibles used for claims such as fire and theft. Percentage deductibles vary from one percent of a home's insured value to 15 percent, depending on many factors that differ by state and insurer.
