Diagnostic Autonomic denied as experimental or investigational by Cigna?

Cigna's specific coverage criteria for diagnostic autonomic 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 Diagnostic Autonomic Testing as Experimental

Cigna's experimental/investigational denial on autonomic nervous system testing reflects a determination by Cigna's clinical team that either (1) the specific test ordered lacks sufficient published evidence of clinical utility in the patient's condition, or (2) the test is not included in Cigna's coverage policy as an established service for the indicated diagnosis. Autonomic testing encompasses a range of modalities, and coverage varies significantly by the specific test, the clinical indication, and Cigna's current medical policy. Some tests in this category have well-established clinical evidence for specific diagnoses; others are more specialized and attract investigational denials more readily.

## Why This Denial Is Appealable

Cigna's experimental determination is based on its internal evidence review, but that review can be wrong, outdated, or inapplicable to your patient's specific diagnosis and clinical context. If the relevant specialty society — such as the American Autonomic Society, the American Academy of Neurology, or another applicable professional organization — recognizes the test as an accepted diagnostic tool for the patient's condition, that professional consensus is powerful appeal evidence. External review is also available, and independent reviewers frequently disagree with payer experimental determinations on diagnostic tests with established specialist use.

## Federal Appeal Framework

• ERISA §503 requires a full-and-fair internal review. Cigna must provide the specific clinical rationale for the experimental determination and the evidence it relied on.
• ACA §2719 mandates external review for experimental/investigational denials specifically — this is one of the strongest use cases for external review.
• External review by a CMS-accredited Independent Review Organization must generally be initiated within four months of the final internal denial.
• Expedited review (72 hours) is available when delay would seriously jeopardize health.
• Request the specific clinical review criteria Cigna applied — you are entitled to this under ERISA.

## Concrete Appeal Steps

1. Request Cigna's full written rationale for the experimental determination, including the specific coverage policy applied and the evidence summary used. 2. Identify the specific test ordered and the clinical indication; obtain the ordering specialist's letter explaining the evidence base and specialty-society support for this test in this indication. 3. Obtain the relevant professional society's position statement or practice guideline recognizing the test (without citing specific statistics — reference the organization and guideline name only). 4. Identify whether Cigna's coverage policy for autonomic testing has a "proven" indication that encompasses your patient's diagnosis, and argue for coverage under that indication if applicable. 5. If the internal appeal is denied, immediately file for external review — external reviewers are substantially more likely to overturn experimental denials for tests with established specialist use.

## Documentation Checklist

• Cigna's denial notice and written experimental/investigational rationale
• Cigna's coverage policy for autonomic testing (request a copy)
• Ordering specialist's letter addressing the evidence base for the test in this specific indication
• Relevant professional society guidelines or position statements (organization and guideline name; no statistics)
• Complete clinical notes documenting the diagnosis, prior workup, and clinical question the test will answer
• Evidence that prior, less specialized tests were insufficient to answer the clinical question (supporting medical necessity and non-duplication)

## Criteria-Mapping Structure

Obtain Cigna's coverage policy for diagnostic autonomic testing and identify the criteria used to distinguish "proven" from "experimental" services. For each criterion, provide the corresponding clinical or evidentiary response. If Cigna's policy lists specific accepted indications, map your patient's diagnosis to the closest accepted indication and explain the clinical equivalence. Attach the specialist's letter as the primary exhibit; the criteria-mapping table should follow immediately after.
