Insulin Pump Tandem denied as non-formulary by Cigna?

Cigna's specific coverage criteria for insulin pump tandem 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 Issues a Non-Formulary Denial for a Tandem Insulin Pump

Cigna's durable medical equipment (DME) benefit structure operates similarly to a formulary — certain devices and manufacturers are on a preferred coverage list, and others require additional justification. A non-formulary denial for the Tandem pump often means one of the following: (1) Cigna has a preferred insulin pump manufacturer on its DME coverage list and treats other manufacturers as non-preferred or non-formulary; (2) the patient's specific plan design does not include the Tandem device in its covered DME schedule; or (3) the specific model or configuration ordered is not listed in Cigna's current coverage policy.

This is a benefit-design determination, but it is not final — most plans are required to offer an exception process, and federal appeal rights apply.

## Why This Denial Is Appealable

• DME exception / formulary exception: Cigna's Evidence of Coverage (EOC) and Summary of Benefits and Coverage (SBC) describe the process for requesting a coverage exception when a non-preferred device is medically necessary because no covered alternative is adequate for the patient.
• Internal appeal (ACA §2719 / ERISA §503): Submit a full-and-fair internal appeal within the timeframe on the denial letter.
• External review: After the internal process, request independent external review under ACA §2719. The reviewer's decision is binding on Cigna. The external-review window is generally within four months of the final internal denial.
• Expedited review: Available for urgent situations.

## Documentation to Gather

1. Plan documents: Pull the patient's EOC and SBC to identify the exact covered-DME language, the preferred device list (if any), and the exception process. 2. Medical necessity for this specific device: The prescriber must explain why the Tandem pump — and not a covered alternative — is medically necessary for this patient. This typically requires documenting clinical features of the Tandem device that are necessary for the patient's care and that are not available in a covered alternative. 3. Inadequacy of covered alternatives: Chart notes and a prescriber letter documenting why any Cigna-preferred pump is clinically inadequate for this patient — for example, incompatibility with a specific continuous glucose monitor system the patient depends on, or clinical features required by the patient's treatment plan. 4. Diabetes management history: Documentation of glycemic control, hypoglycemia episodes, and the clinical context that makes the specific device's features medically necessary. 5. FDA clearance: Confirm that the Tandem model ordered is FDA-cleared for its intended use and include that documentation.

## Criteria-Mapping Structure

For a non-formulary exception, map the appeal to Cigna's own exception language:

| Exception Requirement (from EOC/policy) | Clinical Evidence Supporting Exception | |---|---| | [Copy each exception criterion from Cigna's plan documents] | [Specific chart finding, date, and prescriber attestation] |

Obtain Cigna's current published medical policy for insulin infusion pumps and the FDA-approved labeling for the Tandem device, and reference both in the appeal to confirm the device's clearance and the clinical basis for the exception request.
