BIPAP No Backup denied as not FDA-approved for this use 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) as Not FDA-Approved — and Why You Can Appeal

This denial is unusual for BiPAP devices, because BiPAP without a backup rate is a well-established device category with FDA 510(k) clearance. When Cigna issues a "not-FDA-approved" denial for this device, it typically reflects one of three underlying issues: (1) a coding or billing error where the claim was submitted under a HCPCS code that does not match the device's cleared indication; (2) a documentation gap where the clinical record does not connect the patient's diagnosis to the cleared indication; or (3) Cigna applying an internal coverage standard that effectively requires FDA approval for a specific indication that is narrower than the device's cleared labeling. Understanding which issue drove the denial is the first step in building an effective appeal.

## Federal Appeal Framework

• Internal appeal (ERISA §503 / ACA §2719): You have approximately 180 days from the denial notice to file an internal appeal. Request the full denial rationale and the specific Cigna coverage policy cited, which you are entitled to under ERISA.
• External review (ACA §2719): After the internal process is exhausted, you may request IRO review — typically within approximately four months of the final internal denial. An IRO decision is binding on Cigna.
• Expedited option: Available when a standard timeline would seriously jeopardize your health or ability to function.

## Documentation to Gather

1. Device labeling and 510(k) clearance summary: Obtain the FDA clearance documentation for the specific device prescribed. This directly refutes a claim that the device lacks FDA clearance. 2. HCPCS code verification: Have the supplier confirm that the claim was submitted under the correct code for the device mode (BiPAP without backup rate). A coding correction alone sometimes resolves this denial type. 3. Clinical indication mapping: Physician notes and diagnostic studies showing that the patient's diagnosis maps to the device's cleared indication as stated in the FDA labeling. 4. Prescriber letter: A letter from the ordering provider citing the FDA clearance, referencing the applicable clinical guideline organization (e.g., AASM), and explaining that the device is being used within its cleared indication. 5. Cigna's coverage policy: Download the current policy and identify whether Cigna is applying an approval standard that goes beyond FDA clearance; if so, challenge that standard explicitly.

## Criteria-Mapping Structure

| Denial Basis | Rebuttal Evidence | |---|---| | Device lacks FDA approval | FDA 510(k) clearance number and cleared indication for the specific device | | Indication not covered | Prescriber letter mapping diagnosis to cleared indication | | Coding mismatch | Supplier billing statement with corrected HCPCS code | | [Any other stated basis] | [Targeted evidence from chart or labeling] |

Always base your rebuttal on the actual FDA device labeling and Cigna's current published coverage policy — not summaries — because coverage standards can shift between policy versions.
