Getting an MRI starts with your doctor. In most cases, you cannot simply schedule one yourself. A physician, nurse practitioner, or physician assistant must order the scan, and if you have insurance, that order typically needs approval before the appointment is booked. The process is straightforward once you know what to expect, but it involves a few steps between “I think I need an MRI” and actually lying in the scanner.
Start With Your Doctor
Your primary care doctor or a specialist you’re already seeing is the person who orders an MRI. The key to getting one is communicating your symptoms clearly and specifically. Describe what you’re feeling, how long it’s been going on, what makes it worse, and whether it’s affecting your daily life. Vague complaints are harder for a doctor to act on than concrete details like “my knee has been swollen and locking for six weeks” or “I’ve had daily headaches with vision changes for a month.”
Doctors weigh your symptoms against established criteria for when imaging is warranted. MRIs are covered for a wide range of conditions: head and neurological problems (including multiple sclerosis), spine and disc disease, tumors, joint injuries, bone infections, vascular abnormalities like aneurysms, and organ evaluation for the liver, kidneys, adrenals, and pelvic structures. For disc disease specifically, Medicare’s national policy allows MRI coverage without requiring X-rays or other imaging first. If your situation fits a recognized indication, your doctor has a clear path to ordering the scan.
If your doctor doesn’t think an MRI is necessary, ask why. Sometimes the symptoms genuinely point to a diagnosis that doesn’t require imaging, or a different test would be more useful. Other times, a doctor may be willing to order the scan if you explain your concern more fully. You can also ask for a referral to a specialist, who may have a lower threshold for ordering imaging in their area of expertise. An orthopedist, for instance, orders knee and shoulder MRIs routinely.
How Insurance Approval Works
Once your doctor decides an MRI is appropriate, their office handles the insurance side. They submit a prior authorization request to your insurance company explaining why the scan is medically necessary. This often includes your symptoms, physical exam findings, any treatments you’ve already tried, and sometimes results from earlier tests. The insurance company reviews the request to confirm it meets their coverage criteria.
Standard review can take up to 30 days, though many decisions come back faster. The insurer may request additional documentation before making a decision. If your doctor considers the situation urgent, they can submit an expedited request, which gets a response within 72 business hours. Once approved, both you and your doctor’s office receive the decision in writing, and the office can then schedule your scan.
If the authorization is denied, you have options. Your doctor can appeal the decision with additional clinical information, or you can file a formal appeal through your insurance company. Denials are not always final.
What an MRI Costs
With insurance, your out-of-pocket cost depends on your plan’s copay, coinsurance, and whether you’ve met your deductible. Without insurance, prices vary widely by location and facility. Independent imaging centers tend to be significantly cheaper than hospital-based radiology departments. A standard MRI without contrast generally runs $460 to $800 at independent centers, while scans with contrast range from about $480 to $970. Some cash-pay clinics offer flat rates as low as $350.
Brain, spine, and cardiac MRIs tend to cost more because they use more complex protocols and take longer. Joint scans for a knee or ankle are often on the lower end. If you’re paying out of pocket, call several imaging centers in your area and ask for their cash price. The difference between facilities can be hundreds of dollars for the identical scan.
Choosing Between Open and Closed MRI
When your scan is scheduled, you may have a choice of machine type. A closed MRI is the traditional tube-shaped scanner that surrounds your body. It produces the strongest magnetic field and the sharpest images, and scans tend to be faster. For detailed brain imaging or complex diagnostic questions, closed MRI is generally preferred.
Open MRI machines have a partially open design that leaves space around you rather than enclosing you in a tube. This is a significant option if you experience claustrophobia, are a larger patient, or are getting a scan with a child. The technology has improved considerably, and for many scans (joints, abdomen, spine) open MRI produces results that are just as diagnostically reliable as closed systems. Ask your doctor whether an open MRI would be appropriate for your specific scan, and check whether facilities near you offer one.
Skipping the Referral: Direct-to-Consumer Scans
A growing number of companies now offer MRI scans that you can book yourself without a doctor’s order. Prenuvo, one of the most prominent, charges $999 for a torso scan, $1,799 for head and torso, or $2,499 for a full-body scan. These are marketed as preventive screenings rather than diagnostic tests, and they come with a summary of findings plus a consultation with a clinician on staff.
There are important caveats. The FDA has not approved any MRI machine specifically for preventive screening, though doctors can use the technology however they see fit. Insurance does not cover these scans. And if something abnormal turns up, you’ll still need a doctor to interpret the findings in context and order any follow-up testing. These services make the most sense for people who want proactive screening and are comfortable with the cost, not as a substitute for getting a targeted diagnostic MRI through the standard medical pathway.
How to Speed Up the Process
The biggest delays usually happen at two points: getting the order and getting insurance approval. You can shorten both.
- Come prepared to your appointment. Write down your symptoms with specific details, including duration, severity, and what you’ve already tried (physical therapy, medications, rest). The more clearly you present your case, the easier it is for your doctor to justify the order.
- Ask about authorization timelines. Once the order is placed, call your doctor’s office after a few days to confirm the prior authorization was submitted. Requests sometimes sit in a queue.
- Request urgent review if appropriate. If your symptoms are worsening or your doctor suspects something that needs prompt evaluation, ask whether an expedited authorization request is warranted.
- Be flexible on location. Hospital-based imaging departments often have longer wait times than independent outpatient centers. Ask your doctor’s office if you can choose where to go, then call around for the earliest available appointment.
- Have records ready. If you’ve had prior imaging, lab work, or specialist visits related to your symptoms, make sure your doctor has those records. Insurance companies are more likely to approve quickly when the supporting documentation is complete.
