## Why eviCore Denied on Prior-Authorization Grounds — and Your Appeal Options

A prior-authorization denial for traditional spinal cord stimulation from eviCore means either that authorization was not obtained before the procedure or trial, or that a prior-authorization request was submitted and denied on clinical grounds. eviCore manages prior authorization on behalf of many major insurers, which means your appeal travels through both eviCore's clinical review process and your insurer's formal appeal pathway.

## Procedural vs. Clinical Denials — Know the Difference

If authorization was never requested: your appeal must argue retroactive medical necessity — that the service was clinically appropriate and covered, and that the failure to obtain prior authorization should not negate coverage. Some states require insurers to conduct a full clinical review rather than deny on procedural grounds alone. Identify your state's law before filing.

If authorization was requested and denied: your appeal contests the clinical determination — arguing that the documentation submitted met eviCore's published criteria for SCS and that the denial was not clinically supported.

## Your Federal Appeal Rights

Appeals run through the underlying insurer's formal process. Fully-insured ACA plan members are entitled to external review under ACA §2719 after exhausting internal appeals. ERISA self-funded plan participants have full-and-fair review rights under ERISA §503. The external-review filing deadline is generally four months from the final internal denial notice. If the standard timeline would endanger your health, request expedited review for a 72-hour turnaround.

## Appeal Timeline

1. File Level 1 internal appeal with the underlying insurer, attaching a complete clinical documentation package. 2. Simultaneously request a peer-to-peer review between the implanting physician and the eviCore medical director; document the outcome. 3. File Level 2 internal appeal if offered, then proceed to external review. 4. Track all deadlines from the date on the denial letter, not the date you receive it.

## Documentation to Gather

• Physician medical-necessity letter: a structured letter addressing each of eviCore's published SCS criteria, written specifically for the diagnosis and clinical presentation.
• Diagnosis confirmation: imaging, referring physician notes, and specialist evaluation confirming the qualifying diagnosis.
• Prior-treatment history: a complete timeline of all conservative treatments, with dates, providers, and documented outcomes showing inadequate response.
• Psychological evaluation records: if required by the guideline, document that screening was completed and the outcome.
• Operative or trial notes: if a trial was already performed, documentation of the trial procedure and the patient's response.

## Criteria-Mapping Structure

Download eviCore's published clinical guideline for SCS (available on eviCore's website). Create a table with one row per listed criterion. In the right column, enter the specific chart fact, date, and document reference that satisfies each criterion. Attach labeled supporting documents as exhibits. Submit the table and exhibits together as a single organized PDF to prevent documents from being reviewed in isolation.
