What is meant by "insurance portability"?

Insurance portability primarily refers to the ability of an individual to maintain their health insurance coverage when they switch from one employer to another or change their insurance provider. It allows for the transfer of coverage that ensures individuals do not lose accumulated benefits when moving between plans. This is particularly important in job transitions, where one might have pre-existing conditions or specific benefits that are valuable to them.

While retaining a policy while changing jobs is a component of portability, the emphasis on transferring coverage without losing benefits highlights the essence of the concept. Hence, the correct choice encapsulates the fundamental intention behind portability in insurance practices. The other options tend to focus on aspects that, while related to insurance policies, do not address the core definition of portability in the context of coverage transfer.
