Outpatient Therapy denied as duplicate or overlapping therapy by Aetna?

Aetna's specific coverage criteria for outpatient therapy 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 Aetna Denied Outpatient Therapy as Duplicate Therapy

Aetna's duplicate-therapy denial means the plan determined you are already receiving a service it considers clinically equivalent — for example, a similar therapy modality provided through another benefit category, a concurrent inpatient or partial-hospitalization level of care, or a previously authorized course of the same treatment. These denials are frequently overturned because the services in question are rarely identical in setting, modality, frequency, or therapeutic goal.

## Why This Denial Is Appealable

Payers must approve medically necessary care that is distinct in its clinical purpose. If your outpatient therapy differs in type (e.g., individual vs. group, behavioral vs. occupational), in targeted condition, or in treatment goal from any concurrent service, it is not a true duplicate. Your prescribing or treating clinician is in the best position to articulate why both services are separately necessary.

## Federal Appeal Framework

• ACA §2719 / State External Review: If you are in a non-grandfathered plan, you have the right to an Independent Review Organization (IRO) external review after exhausting internal appeals. The external-review request window is typically around four months from the denial notice — check your Explanation of Benefits (EOB) for the exact deadline.
• ERISA §503 (employer-sponsored plans): You are entitled to a full-and-fair review of the denial. The plan must provide you with the specific criteria used and all documents relied upon.
• Expedited review: If your condition is urgent, request expedited internal and external review simultaneously.

## Appeal Timeline

1. File your first-level internal appeal with Aetna (deadline on your EOB — typically 180 days from denial). 2. If denied internally, request a second-level review if available, or proceed directly to external review. 3. Submit your IRO external-review request before the deadline.

## Documentation to Gather

• Diagnosis confirmation: Current diagnostic records showing the condition(s) being treated by each service.
• Treatment records for each service: Session notes, treatment plans, and progress summaries for both the allegedly duplicative service and the requested outpatient therapy, clearly showing different goals or modalities.
• Prescribing/referring clinician letter: A detailed medical-necessity letter explaining why both services are clinically distinct and concurrently required — not interchangeable.
• Clinical severity documentation: Chart notes documenting functional impairment, symptom burden, or lack of progress that justifies the full scope of care.

## Criteria-Mapping Structure

Pull the exact coverage criteria from Aetna's published clinical policy bulletin for outpatient therapy. For each requirement listed, document the corresponding chart fact:

| Policy Requirement | Supporting Chart Evidence | |---|---| | Services must not duplicate an approved concurrent benefit | Describe how modality, setting, or therapeutic target differs | | Each service must meet independent medical-necessity criteria | Attach separate treatment plans with distinct goals | | Treating clinician supports concurrent authorization | Include signed letter with clinical rationale |
