Artificial Disc Replacement denied for missing prior authorization by Humana?

Humana's specific coverage criteria for artificial disc replacement 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 Denies Artificial Disc Replacement for Prior Authorization

Artificial disc replacement (ADR) is a high-cost elective surgical procedure, and Humana requires prior authorization before it will cover the surgery. A denial coded as "prior-auth-required" most often means the surgery was performed or scheduled without obtaining an approved authorization number in advance, or that a submitted pre-authorization request was denied because the documentation did not satisfy Humana's clinical review criteria at the time of submission.

## Why This Denial Is Appealable

If the authorization was not obtained due to an urgent or emergent clinical situation, an exception pathway exists. If the authorization request was denied on clinical grounds, those grounds are fully appealable through Humana's internal process and, if necessary, external review. Retrospective (after-the-fact) appeals are also available in some circumstances, though the standard is higher — the appeal must demonstrate not only that the procedure was medically necessary but also that the failure to pre-authorize was excusable given the clinical circumstances.

## Your Federal Appeal Rights

• Internal appeal: ACA §2719 and ERISA §503 guarantee a full-and-fair internal review of any adverse benefit determination, including prior-auth denials. File within the deadline on the denial notice.
• External review: If internal appeal is exhausted, an accredited IRO can independently review the denial. The external-review window is generally approximately four months from the final internal decision.
• Expedited review: If clinical urgency applies, request expedited internal and external review simultaneously.

## Documentation to Gather

1. Chronology of the authorization attempt — any fax confirmation, portal submission record, or phone-log notes showing when and how authorization was sought, and the response received. 2. Diagnosis and imaging — MRI and radiology reports confirming the diagnosis, severity, and surgical indication. 3. Conservative-treatment history — a dated list of all prior non-surgical treatments with documented outcomes, showing the progression to surgical candidacy. 4. Surgeon's medical-necessity letter — a signed letter explaining why ADR was necessary, why it could not be delayed pending a renewed authorization submission, and how the patient meets each criterion in Humana's published coverage policy. 5. Referring-physician documentation — any referral notes that informed the surgical decision and timeline.

## Criteria-Mapping Structure

Review Humana's published prior-authorization criteria for ADR (available via Humana's provider portal). List each requirement. For each, cite the specific document and date that satisfies it. If the denial was purely procedural (authorization not sought), frame the appeal around the clinical necessity and request a retrospective exception, attaching all clinical documentation to demonstrate the procedure would have been authorized had the request been made.
