Do I need a referral or an order for an MRI?

You need a provider order for an MRI — not a referral. A referral is a recommendation to see a specialist. A provider order is a formal medical directive that instructs an imaging center to perform a specific test. Imaging centers accept orders, not referrals.

Can any doctor write an imaging order?

Generally yes — any licensed medical provider, including primary care doctors, specialists, urgent care providers, and telehealth providers, can issue imaging orders, subject to state licensing requirements.

What's the difference between an imaging order and a prescription?

A prescription authorizes a pharmacy to dispense a specific medication. An imaging order authorizes a diagnostic imaging facility or laboratory to perform a specific test. They are similar documents with different purposes and different recipients.

What if my insurance requires a 'referral' before imaging?

Insurance companies sometimes use 'referral' and 'order' interchangeably in their documentation. What insurance typically requires is (1) an order from your PCP or specialist, and (2) sometimes prior authorization from the insurance company itself. Check your specific plan documents.
