What is a prescription?

A prescription is defined as an order issued by an authorized prescriber for a drug or medical device intended for a human patient. This document is critical in the healthcare system because it authorizes patients to obtain specific medications that have been deemed necessary for their treatment by a qualified healthcare professional such as a doctor or a nurse practitioner.

In this context, the prescription contains important details such as the name of the patient, the medication prescribed, the dosage, and instructions for use, which ensures that the patient receives the intended treatment safely and effectively. This function distinguishes prescriptions from other healthcare-related documents.

The other options describe different documents or concepts within healthcare but do not accurately define what a prescription is. For example, tracking patient visits is more related to health records and patient management, while a statement of medical necessity pertains to insurance processes rather than direct prescription practices. Similarly, internal forms used by healthcare providers typically do not have the legal standing or specific purpose that a prescription has within the patient's treatment pathway.
