Insulin Pump Tandem denied due to quantity / dose limits 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 May Deny a Tandem Insulin Pump Under Quantity Limits

Cigna's quantity-limit denials for insulin pumps typically arise in one of two situations: the claim is for replacement supplies (infusion sets, cartridges, reservoirs) that exceed the quantity Cigna's policy permits per defined period, or the claim is for a pump replacement before the end of the device's covered useful life as defined in Cigna's policy. Quantity limits for durable medical equipment (DME) are common across commercial insurers and are intended to align with standard clinical usage patterns — but those patterns may not match your individual situation.

## Why This Denial Is Appealable

Quantity-limit denials are among the most routinely overturned on appeal when a prescriber can document that standard quantities are clinically insufficient for the individual patient, or when the device has failed, worn out, or been lost/damaged before the end of its typical covered life. Cigna is required to evaluate requests for quantities exceeding standard limits on a medical-necessity basis.

## Federal Appeal Framework

• Internal appeal: Submit within the deadline on your EOB. Request the specific clinical coverage criteria Cigna used to set the quantity limit and address each one.
• External review: Under ACA §2719, if the internal appeal is denied, you may request an IRO review within approximately four months of the final adverse determination. External reviewers assess whether Cigna's quantity limit determination was consistent with generally accepted medical standards for your specific situation.
• Expedited appeal: If a quantity-limit denial is leaving you without adequate supplies for safe diabetes management, document the urgency clearly and request expedited review.

## Documentation to Gather

1. Diagnosis and clinical context: Chart notes confirming your diagnosis, pump usage history, and any factors that affect supply consumption (e.g., skin sensitivity requiring more frequent site changes, pump malfunctions). 2. Prescriber letter explaining increased need: A letter from your endocrinologist or treating physician documenting why your clinical situation requires quantities exceeding the standard limit — with specific clinical reasoning, not just a request. 3. Device failure or damage records: If the claim involves a replacement pump, documentation of the failure, malfunction, or loss (e.g., manufacturer service records, damage report, police report if lost/stolen). 4. Usage logs or pharmacy records: Records showing your actual consumption pattern and why it is medically justified. 5. Cigna's quantity-limit policy: Obtain the current published criteria from Cigna so you can map each requirement to your chart facts.

## Criteria-Mapping Structure

For each quantity criterion in Cigna's policy, document the specific fact from your chart or prescriber records that demonstrates your situation falls outside the standard-use assumption. Where Cigna's policy allows exceptions for medical necessity, cite each exception provision and the supporting clinical evidence. One-to-one mapping of policy requirement to chart fact is the most effective appeal structure.
