An MRI request form is the clinical order a healthcare provider completes to schedule a magnetic resonance imaging scan. It tells the imaging center what body part to scan, why the scan is needed, and whether contrast dye is required, and it starts the insurance prior-authorization process. If you are the patient, your doctor’s office fills it out; you will complete a separate safety questionnaire at the facility on the day of the scan.
Where the Form Comes From
There is no national MRI request form. Each imaging center, hospital radiology department, and freestanding MRI facility uses its own version, though the required fields are largely the same. The ordering provider’s office usually gets the form in one of three ways: downloading it from the imaging center’s portal, pulling a template from the facility’s electronic health record system, or requesting a blank copy by phone or fax. Some facilities will accept an order written on the provider’s own letterhead if every required field is covered, but using the facility’s form reduces the chance of missing something.
Patient Demographics
The top of the form collects basic identifying information: full legal name, date of birth, sex, address, and a daytime phone number. Most forms also ask for the medical record number and insurance details, including insurer name, policy number, and group number. A sample cardiac MRI form from UCSF, for example, requires the patient’s name, date of birth, height, weight, and a copy of the insurance card alongside the clinical order.1UCSF Benioff Children’s Hospitals. Cardiac MRI Scheduling Request Form
Get the name and date of birth exactly right. A mismatch between the form and insurance records is one of the fastest ways to stall authorization. Match the name on the insurance card, not a nickname.
Clinical Information and Coding
The clinical section is the core of the form. It tells the radiologist what to look for and gives the insurer a reason to approve the scan. Four elements do most of the work: the body part, the clinical reason, an ICD-10 diagnosis code, and a CPT procedure code.
Body Part and Side
The provider must identify the exact anatomical region and, where it applies, which side. “Knee MRI” with no left or right is a common error that forces the imaging center to call back for clarification. If both sides need scanning, most facilities require either separate orders or an explicit notation that a bilateral study is requested.
Reason for the Scan and ICD-10 Code
The form asks the provider to describe why the MRI is needed, either as a brief narrative (“persistent right shoulder pain unresponsive to six weeks of physical therapy”) or by checking a common indication. Alongside that narrative, the provider enters an ICD-10-CM diagnosis code tied to the clinical reason. For low back pain, the current codes are M54.50 (unspecified), M54.51 (vertebrogenic), and M54.59 (other low back pain). The older M54.5 was retired in October 2021 and replaced by these more specific codes.2American Physical Therapy Association. Beginning Oct. 1: Stop Using This ICD-10 Code for LBP Submitting a retired code triggers a rejection.
CPT Procedure Code
The CPT code identifies the exact imaging service and drives billing. CPT 72141, for example, is an MRI of the cervical spine without contrast. Most forms include a field or checklist for the CPT code. If the ordering provider is unsure which code applies, the imaging center’s scheduling staff can usually match it from the body part and contrast instructions, but entering the code up front speeds things along.
Contrast Instructions
The provider has to indicate whether the scan should be done with gadolinium contrast, without contrast, or both. Contrast highlights blood vessels, tumors, and areas of inflammation that may not show clearly on a standard scan. This is not the imaging center’s call. The ordering provider specifies it based on the clinical question. When contrast is requested, extra safety checks apply.
Safety Screening
MRI machines use powerful magnetic fields, which makes certain implants and metallic objects a safety concern. Every request form includes a screening section, and getting it wrong is not just an administrative problem. It can be physically dangerous.
The form typically asks whether the patient has any of the following:
- Cardiac devices such as pacemakers, implantable defibrillators, or stents
- Neurological implants such as aneurysm clips, neurostimulators, or cochlear implants
- Metallic foreign bodies such as shrapnel, bullet fragments, or metal debris in the eyes from welding or grinding
- Orthopedic hardware such as joint replacements, plates, screws, or surgical staples
- Other implants such as insulin pumps, medication ports, or intrauterine devices
A “yes” answer does not automatically rule out a scan. Many modern implants are labeled “MR Conditional,” meaning they can safely enter the magnetic field under specific conditions. The technologist and radiologist need to know in advance so they can verify the safety classification and adjust the protocol. If any answer raises a concern, the charge MRI technologist reviews the case before the scan proceeds.3Martinos Center for Biomedical Imaging. MRI Request Form
The form also asks about pregnancy and claustrophobia. Pregnant patients, particularly in the first trimester, are generally scanned only when the clinical benefit clearly outweighs the theoretical risk. Patients with claustrophobia may need sedation or an open MRI machine, both of which require advance arrangements.
Kidney Function When Contrast Is Ordered
When gadolinium is part of the order, the facility needs to know about kidney function. Gadolinium is cleared through the kidneys, and patients with significantly impaired function face a small but serious risk of nephrogenic systemic fibrosis. Most facilities require a recent serum creatinine result to calculate the estimated glomerular filtration rate. For outpatients, a creatinine within the past three to six months is generally acceptable; for inpatients, within 48 hours of the scan.4National Institutes of Health. Gadolinium-Based Contrast Agents in Kidney Disease
If the patient has a known allergy to gadolinium, note that on the form. The radiologist may pre-medicate with corticosteroids and antihistamines, choose a different contrast agent, or run the scan without contrast.
Who Can Sign the Order
The form must carry the signature of a licensed provider authorized to order diagnostic imaging. Medical doctors and doctors of osteopathic medicine have full ordering authority in every state. Nurse practitioners and physician assistants can order imaging in most jurisdictions, though scope of practice varies by state. Some states require a collaborative agreement with a supervising physician; others grant independent ordering authority.
The signature must be handwritten or applied through an authenticated electronic medical record. Signature stamps are not acceptable under CMS guidelines.5Northwestern Medical Center. Elements for Ordering Diagnostic Imaging Studies By signing, the provider takes professional responsibility for the medical necessity of the scan.
Submitting the Form and Getting It Approved
Once complete, the form goes to the imaging facility through the electronic health record system or by secure fax. Both methods must comply with HIPAA’s standards for transmitting protected health information.6U.S. Department of Health and Human Services. Summary of the HIPAA Security Rule Many facilities now use digital portals that sync the order directly between the provider’s system and the imaging center’s scheduling queue.
For insured patients, the submitted form triggers prior authorization. The insurer reviews the diagnosis code, procedure code, and clinical notes to decide whether the scan meets its criteria for medical necessity.7Centers for Medicare & Medicaid Services. Prior Authorization and Pre-Claim Review Initiatives How long that takes depends on the insurer. Beginning January 1, 2026, plans participating in Medicare Advantage, Medicaid managed care, CHIP, and ACA exchange plans must respond to a standard prior-authorization request within seven calendar days and an expedited request within 72 hours. Commercial plans outside those categories may take longer; many process requests within three to five business days, but there is no single federal rule covering all private insurers.
Why Requests Get Denied
The most frequent reason for denial is insufficient documentation of medical necessity. In practice, that usually means one of three things: the clinical notes did not describe conservative treatments the patient already tried (physical therapy, medication trials, rest), the diagnosis code was too vague or did not match the requested scan, or supporting records from outside providers were missing. Incomplete forms also trigger automatic rejections before a clinical reviewer ever sees the case. A missing signature, a blank diagnosis code, or no contrast specification will all do it.
If authorization is denied, the ordering provider can request a peer-to-peer review, a conversation between the clinician and a medical director at the insurance company to discuss the reasoning behind the order. A peer-to-peer is not itself a decision-making mechanism. It is an opportunity to explain the case; reversing a denial typically still requires a formal appeal.
When Authorization Is Not Required
Not every MRI needs prior authorization. Some plans do not require it for certain scan types, and patients paying out of pocket skip the process entirely.
What Patients Should Know
Your Right to Choose the Facility
When a provider orders an MRI to be performed in the provider’s own office or group practice (known as self-referral), federal law requires the provider to tell the patient in writing that the scan can be obtained elsewhere and to supply a list of at least ten alternative imaging suppliers within 25 miles.8National Institutes of Health. New Patient Disclosure Requirements for Physician Offices This disclosure, added by the Affordable Care Act as an amendment to the Stark Law’s in-office ancillary services exception, applies to MRI, CT, PET, and certain other radiology services ordered for Medicare patients. Some states extend similar protections to privately insured patients. Even when no disclosure law applies, you can ask your provider to send the order to a facility of your choice. Prices for the same scan can differ by hundreds of dollars between a hospital outpatient department and a freestanding imaging center.
Good Faith Estimate for Self-Pay Patients
Patients who are uninsured or who choose not to use their insurance have a legal right to a written good faith estimate of the total expected cost before the scan. Under the No Surprises Act, the facility must provide the estimate within one business day of scheduling if the appointment is booked at least three business days out, or within three business days of scheduling if the appointment is booked ten or more days in advance. You can also request an estimate before scheduling.9eCFR. 45 CFR 149.610 – Requirements for Provision of Good Faith Estimates If the final bill exceeds the estimate by $400 or more, you can dispute the charge through a federal resolution process.
Day of the Appointment
At the facility, you will complete a safety screening questionnaire similar to the section on the request form, but directed at you rather than your provider. Answer every question carefully. The technologist will review your answers and may ask follow-up questions about implants or metallic objects. A few other practical points:
- If your doctor gave you a paper copy of the order, bring it. The facility should already have it electronically, but a paper backup avoids delays.
- You can eat and drink normally before most MRI scans. The main exception is an MRCP (gallbladder and bile ducts), which requires fasting.10University Hospitals. What to Do Before, During and After an MRI
- Remove all jewelry, watches, hair clips, hearing aids, and dentures before entering the scan room. Credit cards and electronic key fobs can be erased by the magnetic field.
- Continue regular medications unless your provider says otherwise.
- If you have been prescribed sedation, arrange for someone to drive you home.
The scan itself typically runs 30 to 60 minutes depending on the body part and whether contrast is used. Results usually reach your ordering provider within a few business days, and your provider’s office will contact you to go over findings and next steps.
