Hereditary Cancer Panel denied for missing prior authorization by Blue Cross Blue Shield?

Blue Cross Blue Shield's specific coverage criteria for hereditary cancer panel 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 This Denial Happens

BCBS requires prior authorization for hereditary cancer panel testing on most plan types. A prior-auth-required denial means the test was performed — or a claim was submitted — without obtaining advance approval, or that the authorization request was submitted but not completed before the service date. These denials are distinct from substantive medical necessity denials: the plan is not saying the test was clinically inappropriate, only that the administrative pre-approval step was missed. Whether the claim can be recovered depends on the circumstances of the authorization failure and the terms of the plan.

## Why This Is Appealable

Prior-auth-required denials are appealable on several grounds: (1) the authorization was obtained but not properly linked to the claim; (2) the service met criteria for a retrospective authorization exception; (3) the patient received inadequate or incorrect information about the authorization requirement; or (4) the plan's prior-auth requirement was not disclosed in a way that gave reasonable notice. In urgent or emergent situations, plans are generally prohibited from denying coverage solely on prior-auth grounds. Review the plan documents and the denial notice carefully to identify which argument applies.

## Federal Appeal Framework

• Internal appeal: File within the deadline on the denial notice (typically 180 days for post-service claims). BCBS must respond within 60 days for post-service standard reviews.
• External review (ACA §2719): After final internal denial, external review is available — generally within four months. Prior-auth disputes that have a medical necessity component are eligible for external review.
• Expedited review: Available for urgent clinical situations.
• ERISA §503: Full-and-fair review rights apply to self-funded plans.
• State surprise billing and prior-auth transparency rules: Some states impose additional obligations on insurers regarding prior-auth disclosure; check whether your state's rules apply.

## Documentation to Gather

1. Authorization records — any confirmation numbers, fax confirmations, or portal records showing an authorization was requested or obtained. 2. Plan documents and EOB — the Summary Plan Description or Evidence of Coverage section describing the prior-authorization requirement and any exceptions. 3. Timeline documentation — dates the test was ordered, when authorization was sought (if at all), and when the test was performed, to support any retroactive exception argument. 4. Ordering clinician's letter — if arguing medical urgency or retroactive exception, the clinician should document the clinical circumstances that led to the service being performed without advance authorization. 5. Communication records — any written or verbal communication with BCBS about coverage or authorization for this test, including call reference numbers.

## Criteria-Mapping Structure

Identify the specific basis for the denial — was authorization never sought, was it denied, or was it obtained but not linked? Build the appeal around that specific fact. If seeking retroactive authorization, use a two-column table listing each criterion BCBS uses for retroactive approval on the left, with the supporting fact on the right. Attach all authorization-related records as labeled exhibits. If the argument is improper notice, quote the plan document language and contrast it with what was communicated to the patient or ordering clinician.
