Yes, each plan is independently owned by the policy holder, even when under the same case number.If this policy is through your employer, you do not have to personally cancel it, they just have to zero you out of their next invoice.If this is a direct policy, I'd encourage you to reach out to the agent who enrolled you for assistance in the paperwork side of things, as the process can be a little confusing.As a representative, I hope you change your mind about canceling. These days no one can afford to not be protected against financial fallout from injury or illness.
