SCS Traditional denied for missing prior authorization 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 Requires Prior Authorization for Traditional SCS

Traditional spinal cord stimulation is a high-cost surgical implant procedure, and Humana requires prior authorization for both the SCS trial phase and the permanent implant phase. A "prior-auth-required" denial most commonly arises in one of three scenarios: (1) the procedure was performed or scheduled without obtaining authorization in advance; (2) an authorization was obtained but the claim does not match the authorized procedure, device, or facility; or (3) an authorization request was submitted but denied because the required clinical documentation was not included, leaving the authorization technically unissued.

## Why This Denial Is Appealable

If the procedure was performed emergently or urgently and prior authorization was not feasible, most plans — including Humana's — include a retroactive authorization or emergency exception pathway. If the denial is a documentation failure, an appeal with complete clinical records can result in authorization and claim payment. If authorization was denied on clinical grounds, that determination is a medical-necessity decision subject to full internal and external appeal rights.

## Your Federal Appeal Rights

• Internal appeal: File under ERISA §503 (employer plan) or Humana's grievance and appeals process. Distinguish clearly whether you are appealing (a) a retroactive authorization denial, (b) a prior-authorization denial on clinical grounds, or (c) an administrative mismatch — each has a different argument.
• External review (ACA §2719): If the prior-authorization denial is based on medical-necessity criteria, it is eligible for binding independent external review. The window is generally up to four months from the denial notice.
• Expedited review: If the SCS trial has already begun or the permanent implant window is time-limited, request expedited review.

## Documentation to Gather

1. Authorization request and denial records — copies of the original PA submission, any Humana acknowledgment, and the denial notice with reason codes. 2. Diagnosis and clinical summary — the treating physician's documentation supporting the SCS indication, organized to match Humana's published SCS coverage criteria. 3. Prior treatment history — dated record of conservative and interventional treatments tried and failed, with outcomes. 4. Psychological evaluation — if required by Humana's SCS policy, include the formal clearance evaluation. 5. Prescriber letter — a letter from the implanting physician stating medical necessity, confirming the diagnosis, and addressing any specific clinical criterion Humana cited as deficient in the authorization denial. 6. Timeline documentation — if a retroactive authorization is sought, document the clinical circumstances that precluded advance authorization, and cite Humana's emergency/urgent exception language.

## Criteria-Mapping Approach

Obtain Humana's SCS prior-authorization criteria (available through Humana's provider portal or by written request). For each criterion, cite the specific chart record — with date and document type — that satisfies it. If Humana denied authorization and cited a specific missing element, make that element the first exhibit in your appeal. Structure the appeal as a direct point-by-point response to the denial rationale, not a general narrative.
