## Why eviCore Issued a Non-Formulary Denial for an Implantable Device — and Why It Is Appealable

A "non-formulary" denial applied to traditional spinal cord stimulation is unusual because SCS is a surgical procedure, not a pharmacy benefit. When eviCore uses this label, it typically means the specific device manufacturer or model is not on the insurer's preferred device list, or that the procedure was classified under a benefit tier that requires separate authorization. Understanding the precise basis of the non-formulary designation is the first step in the appeal.

## The Core Argument

FDA-cleared conventional SCS devices are interchangeable from a regulatory standpoint in terms of their fundamental cleared indication. If an insurer has a preferred-device policy, the appeal should ask: (1) Is the preferred device clinically equivalent for this patient's anatomy and diagnosis? (2) Did the prescribing physician have a documented clinical reason to select the specific device? If the physician's selection was driven by clinical factors — lead geometry, rechargeable vs. non-rechargeable, MRI compatibility — document those reasons explicitly. Clinical differentiation defeats a non-formulary denial.

## Your Federal Appeal Rights

After exhausting internal appeals, ACA fully-insured plan members can request external review under ACA §2719. ERISA self-funded plan participants have full-and-fair review rights under ERISA §503. The external-review filing window is generally four months from the final internal denial. Expedited review (72-hour turnaround) is available for urgent situations.

## Appeal Timeline

1. Request the specific reason the device is classified as non-formulary and the list of preferred devices. 2. File Level 1 internal appeal, including a physician letter explaining the clinical rationale for device selection. 3. If denied, escalate to external review within the four-month window.

## Documentation to Gather

• Physician device-selection rationale: a letter documenting the clinical reasons the specific device was chosen — such as MRI compatibility requirements, body habitus, programming flexibility, or rechargeable vs. primary cell considerations — and why a preferred alternative is clinically inferior or inappropriate for this patient.
• Device FDA clearance and IFU: confirming the device's cleared indications.
• Diagnosis and anatomy documentation: imaging and chart notes supporting the clinical rationale.
• List of preferred alternatives: obtained from eviCore or the insurer, to address why each alternative is not appropriate.

## Criteria-Mapping Structure

Obtain eviCore's published guideline and the insurer's medical policy on SCS. Map each coverage criterion to chart documentation. For the non-formulary issue specifically, attach a separate section addressing the device-selection rationale and why preferred alternatives are not clinically equivalent for this patient. This targeted argument, backed by the physician letter, is the most effective path to reversal.
