Disability insurance provides income benefits if a person is unable to work due to illness or injury. There are two main types: short-term disability has a maximum benefit period of up to two years, while long-term disability has a maximum period ranging from a few years to life. Coverage can be for inability to work in your own occupation or any occupation. Most plans do not cover disabilities from drug abuse, suicide attempts, war or crimes. Protection features include policies being noncancelable or guaranteed renewable.
