Insurance companies deny 18% of claims automatically. But 80% of appeals succeed when done right. We ensure yours is one of them—in minutes, not months.
Our AI generates evidence-based letters that address the specific reason for denial—not generic templates.
Dear BlueCross BlueShield Appeals Review Committee,
I am writing to formally appeal the denial of coverage for the lumbar spine MRI (CPT code 72148) ordered by my treating physician, Dr. Jennifer Martinez, Board-Certified Orthopedic Surgeon. This imaging study is medically necessary to diagnose the source of severe, persistent lower back pain that has failed to respond to six months of conservative treatment.
Clinical Background and Diagnosis
I have been experiencing severe lower back pain radiating into my left leg for the past eight months. The pain is constant, rated 7-8/10, and significantly impacts my ability to work as a high school teacher—I cannot stand for more than 20 minutes without severe discomfort. The pain is accompanied by numbness in my left foot and weakness in my left calf.
Objective Clinical Evidence
Physical examination by Dr. Martinez revealed positive straight leg raise test on the left at 30 degrees, reduced left ankle reflexes, and measurable muscle weakness (4/5 strength) in left ankle dorsiflexion. These are objective findings consistent with nerve root compression...
Treatment History and Medical Necessity
I have completed the full spectrum of conservative treatments over six months:
• 12 weeks of physical therapy (January-March 2026) with minimal improvement
• Trial of NSAIDs including ibuprofen 800mg TID and naproxen 500mg BID—provided only temporary relief
• Epidural steroid injection on February 20, 2026—no sustained benefit
• Muscle relaxants (cyclobenzaprine) and neuropathic pain medication (gabapentin)—inadequate response
Direct Rebuttal of Denial Reason
The denial states this imaging is "not medically necessary." However, this determination contradicts established medical standards. The American College of Radiology Appropriateness Criteria specifically recommend MRI for patients with radicular symptoms and clinical findings suggestive of nerve root compression who have failed conservative therapy...
Each step addresses the specific failure modes that cause well-intentioned appeals to be rejected. Nothing is generic.

Our AI adapts the entire strategy based on WHY you were denied—not one-size-fits-all templates
Appeals formatted exactly how insurance reviewers expect to see them—increasing approval odds
We collect the data points insurers actually use to approve—diagnosis, prior treatments, clinical findings
Every letter highlights your treating physician's expertise and requests peer-to-peer review
What takes attorneys hours or days, our AI does in 10 minutes—without sacrificing quality
Insurance companies use AI to deny claims in as little as 1.2 seconds. No qualified physician reviews your case. The denial is financial engineering — not medical judgment.
Under the ACA and ERISA, every formal appeal must receive a "full and fair review" by a qualified human reviewer. Employers administering health plans are held to a legal fiduciary standard. They cannot delegate that responsibility to an algorithm.
This is why appeals succeed at rates reaching 70–96%. The initial denial is automated. The appeal forces a real person to read a real document.
The question is not whether to appeal. The question is whether what they read is good enough to win.
KFF data shows 83% of prior authorization appeals are overturned when properly challenged. Most self-filed appeals fail not because the denial was correct — but because of how the appeal was written.
Data from KFF, AMA, Commonwealth Fund, and industry insiders — the most authoritative sources on insurance denials in the United States.
Following the murder of a UnitedHealthcare executive in December 2024, public attention on systematic denials reached a historic high — forcing insurers to publicly acknowledge the problem.
Multiple major insurers committed to reducing prior authorization requirements in 2024–2025. 31 states passed reform legislation. Commitments remain largely unverified.
Five insurance CEOs testified before Congress in January 2026. Senators from both parties cited constituent stories of delayed care, preventable deaths, and denials overturned within hours of appeal.
Most insurance appeals have a 180-day filing window from the date of denial. Once that window closes, you permanently lose your right to appeal—even if the denial was completely wrong. Start your appeal now to preserve your coverage rights.
