What does the term "expired" refer to?

The term "expired" specifically refers to a date of validity that has passed. In the context of licenses, certifications, or any time-sensitive documents, "expired" indicates that the allowance or permission granted by the document is no longer valid after a specified date. For example, if a chiropractor's license states it is valid until a certain date, once that date has passed, the license is considered expired and the practitioner can no longer legally practice until they have renewed or re-certified their license. Understanding this term is crucial for maintaining compliance with regulatory requirements and ensuring that practitioners are properly licensed to provide care.

In contrast, the other options deal with unrelated aspects of a patient’s treatment or status and do not encompass the legal and operational implications of expiration in a professional context.
