Open Enrollment Period Varies from Plan to Plan

Health Insurance Enrollment Period

Open Enrollment is a time period during which you are eligible to sign up for a health insurance plan. If you fail to sign up for health insurance during the open enrollment, then you will not be able to sign up for a health plan until the next open enrollment period, with the only exception that you experience a qualifying event. If you are eligible for a health plan, and you apply for health insurance during the open enrollment, then the insurance company should provide you the plan and the company is not allowed to use underwriting or require proof of insurability because both these options will make it difficult for you to obtain health insurance. Open enrollment periods are commonly in place for health plans like Medicare, Job-based health insurance, and Individual market health insurance plans. Enrollment windows apply for ACA compliant plans that are available in the health insurance exchanges and outside the exchanges.
