Spinal Surgery Insurance Denied: How to Appeal a Spine Surgery Denial

Spinal surgery denials are among the most consequential insurance disputes — affecting people who are often in significant pain and whose quality of life and ability to work depends on receiving the procedure. Insurers deny spinal surgery claims at a high rate, frequently arguing that "conservative treatment" hasn't been sufficiently attempted or that the surgery isn't "medically necessary." These denials are often wrong and can be successfully appealed.

Common Types of Denied Spinal Procedures

• Discectomy / microdiscectomy — removal of herniated disc material compressing a nerve
• Laminectomy / decompression — removal of bone and tissue to relieve spinal canal pressure
• Spinal fusion — fusing vertebrae to stabilise the spine
• Vertebroplasty / kyphoplasty — injection of bone cement for vertebral compression fractures
• Spinal cord stimulator (SCS) implantation — for chronic spinal pain management
• Artificial disc replacement — disc arthroplasty as an alternative to fusion

Why Spinal Surgery Claims Are Denied

Conservative treatment not exhausted: The most common denial. Your insurer argues you should try physical therapy, medication, injections, or other non-surgical treatments before surgery will be approved. If your records don't clearly show adequate conservative treatment attempts, this argument can stick.

Medical necessity not established: Your insurer's clinical reviewer determines the surgery doesn't meet its medical necessity criteria — often using criteria that are more restrictive than accepted surgical guidelines.

Functional impairment not adequately documented: Insurers frequently deny spinal surgery for patients who appear to function adequately based on submitted records, even when the patient is in significant pain and has quality-of-life impairment.

Imaging findings not meeting criteria: The insurer may argue that your MRI or CT findings don't meet their threshold for surgical intervention — even when your surgeon disagrees.

"Experimental" classification for certain procedures: Some newer spinal procedures, or procedures for certain diagnoses, may be classified as experimental or investigational by some insurers.

Second surgical opinion required: Some insurers require a second surgical opinion before approving elective spinal surgery.

Spinal cord stimulator denials: SCS implantation is frequently denied for not meeting coverage criteria or for insufficient documentation of failed conservative pain management.

Building the Medical Necessity Case

A successful spinal surgery appeal requires comprehensive documentation that directly addresses your insurer's criteria:

1. Conservative treatment history:

• Detailed records of all conservative treatment attempted: physical therapy (PT) with specific dates, duration, number of sessions, and outcomes; chiropractic treatment; epidural steroid injections; medications tried and failed
• Your physician's assessment of why additional conservative treatment is unlikely to be beneficial and why surgery is now indicated
• Duration of symptoms — most surgical coverage criteria require symptoms of a certain minimum duration

2. Imaging documentation:

• MRI and/or CT reports clearly showing the pathology your surgeon is treating
• Correlation between imaging findings and your symptoms
• Radiologist's report language that specifically identifies the relevant findings

3. Neurological examination:

• Objective neurological findings: muscle weakness, sensory deficits, abnormal reflexes, positive straight leg raise, myelopathy signs
• These objective findings significantly strengthen the medical necessity case

4. Functional impact:

• Objective functional assessment documenting how your spinal condition limits your activities of daily living, work capacity, and quality of life
• Pain scale documentation over time
• Validated outcome measures (Oswestry Disability Index, Visual Analogue Scale)

5. Surgeon's detailed letter:

• Your spine surgeon's letter is the centrepiece of the appeal
• Should explain: the specific diagnosis, why surgery is the appropriate treatment, what conservative treatments have been attempted and why they failed, what the risks of not having surgery are, which specific procedure is planned and why it is superior to alternatives, and how the patient meets the surgical criteria
• Should directly reference your insurer's coverage criteria for the denied procedure

Step-by-Step: Appealing a Spinal Surgery Denial

Step 1: Read the Denial Carefully

Your insurer's denial notice will specify the medical necessity criteria or coverage criteria being applied. Get a copy of the insurer's clinical guidelines for the specific procedure denied. Request these from the insurer — they must provide them.

Step 2: Have Your Surgeon Write a Detailed Appeal Letter

This is the single most important step. Your surgeon's letter must:

• Address the insurer's specific criteria point by point
• Document the clinical findings supporting surgery
• Explain why conservative treatment has been adequate or why further conservative treatment is contraindicated
• Reference clinical guidelines from the North American Spine Society (NASS), American Academy of Orthopaedic Surgeons (AAOS), or American Association of Neurological Surgeons (AANS)
• Specify the risks of continued non-surgical management

Step 3: Obtain All Conservative Treatment Documentation

Pull together all records from PT, injections, chiropractic, and pain management. If conservative treatment was performed by other providers, ensure those records are in your appeal package.

Step 4: Request a Peer-to-Peer Review

Many insurers allow (and some require) the treating surgeon to have a direct peer-to-peer review call with the insurer's reviewing physician. This conversation is often more effective than written appeals because:

• Surgeons can advocate directly for the clinical need
• The reviewing physician can ask clarifying questions
• Misunderstandings about imaging findings or clinical findings can be corrected

Request this specifically from your insurer.

Step 5: Obtain an Independent Surgical Opinion

If your insurer is disputing the clinical basis for surgery, obtain an independent second opinion from another board-certified spine surgeon (not the operating surgeon). A letter from a second independent surgeon supporting the surgical indication strengthens your appeal significantly.

Step 6: Submit Your Appeal

Include:

• Your appeal letter
• Surgeon's detailed letter
• All conservative treatment records
• Imaging reports and images (if possible)
• Neurological examination findings
• Functional assessment
• Independent surgeon's opinion (if obtained)
• Clinical guidelines supporting the surgery

Step 7: Request External Review

After exhausting internal appeals, request external review by an Independent Review Organisation (IRO). For spinal surgery denials, request that the IRO reviewer have orthopaedic spine or neurosurgical expertise. External review frequently reverses spinal surgery denials when the clinical documentation is strong.

Step 8: File a State Insurance Complaint

If you believe your insurer is applying more restrictive criteria than national guidelines warrant, file a complaint with your state's Department of Insurance.

Tips for Specific Procedures

Spinal fusion: Fusion is particularly scrutinised by insurers. Emphasise instability (spondylolisthesis, fracture), failed prior decompression, or degenerative disc disease with documented functional instability. NASS evidence-based guidelines support fusion for specific indications.

Spinal cord stimulator: SCS is typically covered after documented failure of conservative measures including multiple injection modalities. Ensure your records show all prior treatment attempts. Some insurers require formal psychological evaluation before SCS.

Disc replacement: Artificial disc replacement is sometimes classified as investigational for certain levels or diagnoses. Request your insurer's specific coverage criteria and address each criterion.

Conclusion

Spinal surgery insurance denials are common but frequently reversible. The key is comprehensive, objective medical documentation — conservative treatment history, imaging correlation with symptoms, neurological findings, functional impact, and a detailed surgeon's letter addressing the insurer's criteria directly. Request a peer-to-peer review, escalate to external review, and don't accept the first denial as the final answer.
