Short answer

A physician assistant is a licensed clinician who practices medicine on a physician-led team - and despite 'assistant,' they are not a helper: they diagnose, manage treatment plans, prescribe, perform procedures, and often serve as your principal clinician.

The road in is a graduate degree built on the medical model plus national certification and state licensure, per MedlinePlus's provider guide. Versus a doctor: shorter training, formally collaborative practice, with independence varying by state. Versus a nurse practitioner: a different training model - medicine rather than nursing - though the two look nearly identical from the patient's chair in primary care. Practically, PAs staff huge shares of urgent care, ERs, surgery, and primary care, and are often the fastest way into a good practice.

Common questions

What is a physician assistant?

A physician assistant (PA) is a licensed medical clinician who practices medicine on a team with physicians - and despite the word 'assistant,' they are not a helper or a trainee: they diagnose illnesses, develop and manage treatment plans, prescribe medications, perform procedures, and often serve as your principal clinician. The road in: a graduate degree (typically a three-year masters) built on the medical model - the same disease-and-treatment framework physicians use - following a science-heavy undergraduate path, with national certification and state licensure. MedlinePlus's guide to provider types lists PAs among the licensed clinicians who diagnose and treat. How the PA differs from the two roles people confuse them with: versus a doctor, the training is shorter and the practice is formally collaborative with physicians (the level of independence varies by state and setting); versus a nurse practitioner, the training model differs - NPs come up through nursing, PAs through medicine - though day-to-day in primary care the two roles look nearly identical from the patient's chair. Practically: PAs staff huge shares of urgent care, emergency medicine, surgery, and primary care, and booking with one is often the fastest way into a good practice.
