Which terms have the same meaning as "subscriber"?

The term "subscriber" refers to the individual who holds an insurance policy and is primarily responsible for the insurance coverage. This person typically pays the premiums and is often the one who receives medical benefits under the policy. In health insurance contexts, a subscriber is synonymous with the term "insured," as both terms describe the individual entitled to the health benefits and coverage provided by the insurance plan.

In contrast, a "new patient" refers to someone who is visiting a physician for the first time and has no prior visit history with that provider. An "established patient" is someone who has previously been treated by the provider and therefore has a history of care with that practice. "Guardian" specifically denotes a person who has legal authority to care for another person, typically a minor, and may or may not hold an insurance policy themselves. These terms do not denote the financial responsibility or relationship to the insurance policy that "subscriber" and "insured" do, which is why they do not share the same meaning.
