Why Florida Insurers Deny MRI Claims

Prior authorization not obtained or denied upfront. Florida's dominant commercial insurers — Florida Blue (BCBS), UnitedHealthcare, Aetna, Cigna, and Humana — all require prior authorization for MRI. Denial at the authorization stage is the most common reason patients never get their scan covered.

Medical necessity determination. Insurers use InterQual or proprietary criteria to evaluate MRI requests. Common denials include MRI for low back pain without neurological deficits, knee MRI before conservative care is tried, and brain MRI for non-specific headaches.

Out-of-network imaging center. Florida has numerous freestanding imaging centers, and not all are in every insurer's network. If your physician referred you to an out-of-network facility, your claim may be denied or substantially underpaid.

Coordination of benefits issues. Florida has a large Medicare Advantage population. If you have both Medicare Advantage and a supplemental plan, coordination of benefits errors can result in denials from one or both carriers.

Frequency limitations. Follow-up MRIs for stable conditions — such as annual brain MRIs for MS patients — are denied when insurers determine the prior scan was recent enough.

How to Appeal an MRI Denial in Florida

Step 1: Get the full denial in writing. Florida law requires insurers to provide a written explanation of denial with the specific clinical criteria applied. Review this carefully — the language of the denial often tells you exactly what documentation to provide on appeal.

Step 2: File an internal appeal. You typically have 365 days from the denial to file an internal appeal with your insurer. Submit:

• A physician letter of medical necessity with clinical detail
• Supporting medical records (office visit notes, previous imaging reports, lab results)
• Clinical guidelines or peer-reviewed studies supporting your MRI
• Any documentation of failed conservative treatment (if step therapy is the barrier)

Insurers must respond to internal appeals within 30 days (standard) or 72 hours (expedited).

Step 3: Peer-to-peer review. Your ordering physician can request a peer-to-peer call with the insurer's medical director. This single call reverses a significant percentage of imaging denials, especially when the physician can explain the urgency or the limitations of prior conservative treatment.
