SCS Traditional denied as non-formulary by Humana?

Humana's specific coverage criteria for scs traditional are defined in its own published medical/coverage policy and the FDA-approved prescribing label. A successful appeal documents that your medical records satisfy each criterion those sources list — confirmed diagnosis, any required prior treatments (with dates and outcomes), and clinical severity. If the exact criteria weren't included with your denial, request them in writing; your appeal then maps each requirement to the matching fact in your chart.

## Why Humana May Issue a Non-Formulary Denial for Traditional SCS

Although spinal cord stimulation is a procedural/device intervention rather than a pharmacy benefit, Humana may apply a "non-formulary" or "not on plan" classification to specific SCS device systems, particularly newer or premium-tier devices from manufacturers whose systems are not on Humana's preferred device list or contracted implant schedule. This denial type can also arise when the authorization request is routed through the wrong benefit category — for example, when a device-based therapy is incorrectly reviewed against the pharmacy formulary rather than the durable medical equipment or surgical implant benefit.

## Why This Denial Is Appealable

A non-formulary denial for a surgical implant requires scrutiny of two distinct questions: (1) Is the classification itself correct — i.e., does the device truly fall outside the applicable benefit, or was it misrouted? (2) Even if the device is non-preferred, does the plan allow exceptions when a preferred alternative is clinically inadequate or contraindicated for this patient? Most plans include a medical-necessity exception pathway for non-preferred devices. Establishing that the physician selected this specific device system for documented clinical reasons (e.g., rechargeable vs. non-rechargeable based on patient dexterity; MRI-conditional status; specific waveform requirements) can support an exception request.

## Your Federal Appeal Rights

• Internal appeal: File a written appeal under ERISA §503 or Humana's grievance procedures, requesting both (a) clarification of which benefit category applies and (b) medical-necessity exception review.
• External review (ACA §2719): If the denial is grounded in a medical-necessity or clinical-criteria determination (i.e., whether this device is appropriate for this patient), it qualifies for independent external review. Window is generally up to four months from denial.
• Expedited review: Available for urgent situations.

## Documentation to Gather

1. Device-specific clinical rationale — a letter from your implanting physician explaining why this specific SCS system was selected over any Humana-preferred alternative, citing patient-specific clinical factors (e.g., need for MRI compatibility, rechargeability based on patient profile, specific programmability requirements). 2. FDA clearance for the device — confirming the specific model is cleared for your diagnosis and implant configuration. 3. Benefit category clarification — request from Humana in writing which benefit category governs SCS devices and the specific policy or plan document provision that classifies this device as non-formulary. 4. Plan document review — obtain the Summary Plan Description or Evidence of Coverage and locate the device/implant benefit language and any exception process. 5. Alternatives analysis — if Humana identifies a preferred device, the physician should document in writing whether that alternative is clinically appropriate for this patient and why or why not.

## Criteria-Mapping Approach

Address the non-formulary classification and the medical-necessity exception as two parallel tracks in your appeal. For the classification track, cite the plan document's device benefit language. For the exception track, quote the exception criteria from Humana's policy and map each one to the physician's documentation of patient-specific clinical need.
