Ground Ambulance denied as duplicate or overlapping therapy by Humana?

Humana's specific coverage criteria for ground ambulance 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 Humana Denied Your Ground Ambulance Claim as Duplicate Therapy — and How to Appeal

A "duplicate therapy" denial applied to a ground ambulance transport is unusual and often reflects a claims-processing error rather than a genuine clinical determination. Humana's system may have flagged the ambulance claim because another transport service or a prior ambulance claim was billed for the same date of service or a closely adjacent episode. Because ground ambulance is an emergency medical service — not a "therapy" in the clinical sense — this denial category typically does not fit the facts and is highly likely to succeed on appeal.

## Federal Appeal Rights

• ACA §2719 / External Review: Non-grandfathered health plans must offer independent external review after internal appeals are exhausted. The request window is generally within four months of the final adverse benefit determination. An expedited review (72-hour decision) is available when your health is at serious risk.
• ERISA §503: If your plan is employer-sponsored and self-funded, ERISA entitles you to the specific denial rationale and all relevant criteria, plus the right to submit rebuttal evidence.
• No Surprises Act (ground ambulance context): Federal surprise-billing protections are expanding for ground ambulance services; confirm the current rules that apply to your plan and service date.

## Appeal Process and Timeline

1. Obtain the Explanation of Benefits and the denial letter specifying exactly which "duplicate" claim Humana identified. 2. Request the claims history from Humana for the date of service to identify the alleged duplicate. 3. File a Level 1 internal appeal within the deadline on your EOB — typically 180 days from the adverse determination. 4. If denied internally, file for external review within the four-month window.

## Documentation to Gather

• Ambulance call report (ACR) / patient care report (PCR): The crew's contemporaneous record of the emergency call, response time, patient condition at scene, and clinical interventions during transport.
• Hospital emergency records: Admit time, chief complaint, and treating physician notes that confirm the medical emergency requiring transport.
• Evidence that no prior transport was provided for the same episode: Obtain written confirmation from the ambulance provider that no duplicate claim was submitted and that the transport is unique.
• Prescriber or treating physician letter: A statement from the ED physician or treating provider that emergency ground transport was medically required.

## Criteria-Mapping Strategy

Pull Humana's published coverage policy for ground ambulance services and identify any provision that could be misapplied as "duplicate therapy." In the appeal, demonstrate point-by-point that: (a) there was only one transport event, (b) no overlapping claim for the same episode exists, and (c) the "duplicate therapy" denial category is facially inapplicable to emergency medical transport. Attach the ACR and hospital records as primary evidence. If the denial resulted from a billing code error, include a corrected claim with an explanation from the billing provider.
