health insurance open enrollment

What is open enrollment? In terms of health care insurance??

It’s a specified period of time when anyone who is a member of a group, such as an employee of a company, can enroll himself or family members into his company’s group insurance plan without having to supply evidence of insurability (medical records, etc.) if he wasn’t already enrolled in the insurance program. This term usually applies to group health insurance programs. If you’re considering getting involved in your employer’s group health plan, open enrollment is the best time to do it.
