Maria's MRI Was "Not Medically Necessary" — Her Doctor Disagreed

Maria, 52, had been dealing with chronic lower back pain for eight months. Her doctor ordered an MRI to check for a herniated disc. Two weeks later, an EOB arrived: her insurance had denied the claim. "Service not medically necessary." No MRI. No explanation beyond four words.

Her doctor was furious. He had documented eight months of treatment, failed physical therapy, and worsening symptoms. None of that seemed to matter.

"My doctor has treated me for eight months. He went to medical school. He examined me. How can an insurance company — who has never met me — decide what I medically need?"

Maria almost just accepted it. She figured insurance companies always win. Most people do.

"Not medically necessary" is the most common claim denial reason — and it's frequently wrong or improperly applied. Insurers use it to cut costs, often automatically, without a physician ever reviewing your specific case.

What most people don't know: you have a legal right to appeal every denial. There are two levels. An internal appeal asks the same insurer to review its decision. An external appeal goes to an independent third party — not affiliated with the insurer — who makes a binding final decision. Under the ACA, insurers must respond to urgent internal appeals within 72 hours.

1. 1
   Maria used BillVeil's Denial Fighter and entered her denial reason and procedure.
2. 2
   She got a customized appeal letter citing her insurer's own published medical necessity criteria for MRI — criteria her situation clearly met.
3. 3
   Her doctor added a supporting letter documenting eight months of failed conservative treatment.
4. 4
   She filed the internal appeal with both documents. The insurer had 30 days to respond.
5. 5
   They approved it on day 18.

MRI approved. Maria had her scan within the week — it confirmed a herniated disc at L4-L5, which changed her treatment plan entirely. The appeal letter took 25 minutes to write with BillVeil's help.
