BIPAP No Backup denied as not medically necessary by Cigna?

Cigna's specific coverage criteria for bipap no backup 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 Cigna Denies BiPAP (Without Backup Rate) for Medical Necessity — and Why You Can Appeal

Cigna's medical-necessity denials for BiPAP therapy without a backup rate typically occur when the clinical documentation submitted does not clearly establish that the patient's respiratory condition requires this specific device mode rather than a simpler alternative (such as CPAP). Reviewers may conclude that the record does not demonstrate severity sufficient to justify BiPAP, or that required diagnostic studies were not interpreted in a way that maps to Cigna's coverage criteria. These denials are routinely overturned on appeal when the prescribing physician provides a detailed medical-necessity letter and the record is organized to answer each criterion directly.

## Federal Appeal Framework

You have layered appeal rights regardless of how your plan is structured:

• Internal appeal (ERISA §503 / ACA §2719): Cigna must provide a full-and-fair internal review. You typically have 180 days from the denial notice to file.
• External review (ACA §2719): After exhausting internal appeals — or if Cigna takes too long — you can request an Independent Review Organization (IRO) review. The external-review window is generally within approximately four months of the final internal denial. IRO decisions adverse to Cigna are binding.
• Expedited review: If waiting for standard review would seriously jeopardize your health, request expedited internal and external review simultaneously. Decisions are required within days, not weeks.

## Documentation to Gather

1. Diagnosis confirmation: Sleep study reports (polysomnography or home sleep test), interpreting physician notes, and any pulmonology or sleep-medicine consultation records that establish the underlying diagnosis. 2. Prior-treatment history: Dates of any prior CPAP trial, adherence records, and documented reasons why CPAP was inadequate or contraindicated for this patient. 3. Clinical severity: Physician chart notes describing symptom burden, functional impact, and objective findings that support the need for BiPAP specifically. 4. Prescriber medical-necessity letter: A detailed letter from the ordering provider explaining why BiPAP without a backup rate is the appropriate device, referencing the applicable guideline organization (e.g., the relevant AASM guideline) and stating that the patient meets each of Cigna's published coverage criteria. 5. Cigna's own coverage policy: Download the current Cigna Coverage Policy for respiratory-assist devices and print each criterion; your appeal should address every line.

## Criteria-Mapping Structure

Build a two-column table in your appeal letter:

| Cigna Coverage Requirement (from policy) | Supporting Evidence in the Chart | |---|---| | Diagnosis of [condition per policy] | Sleep study dated [date], interpreted by [provider] | | Documented trial or failure of less-intensive therapy | CPAP trial [dates], adherence report, prescriber notes | | [Each additional criterion listed in the policy] | [Exact chart reference: note date, page, finding] |

Obtain the exact eligibility thresholds and device specifications from (a) the FDA 510(k) clearance and product labeling for the prescribed device and (b) Cigna's current published medical policy — do not rely on memory or third-party summaries, as these criteria change. Match each threshold precisely to a chart value documented before the denial date.
