Many individuals do not buy individual health insurance coverage, since they assume that they’re adequately covered under their employer’s group health policy. But it’s wise to always opt for a separate medical insurance plan, because your employer’s policy might not be comprehensive enough to cover the medical needs of your entire family. Also, if you ever decide to leave your job, you risk losing that coverage.
