Robotic Gait denied as duplicate or overlapping therapy by Blue Cross Blue Shield?

Blue Cross Blue Shield's specific coverage criteria for robotic gait 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 BCBS Denies Robotic Gait Training as Duplicate Therapy

Blue Cross Blue Shield may deny robotic-assisted gait training on duplicate-therapy grounds when a patient is already receiving — or recently received — conventional physical therapy or other gait rehabilitation services. BCBS's position is that the robotic device provides the same therapeutic benefit as already-authorized therapy, making the additional service redundant and therefore not reimbursable. This framing is often clinically incorrect: robotic gait training systems provide task-specific, high-repetition locomotor training with real-time biofeedback and weight-support capabilities that conventional therapy cannot replicate, and the two modalities address different neurological mechanisms of recovery.

Duplicate-therapy denials for robotic gait training are frequently overturned when the prescribing team clearly articulates how the two interventions are clinically distinct.

## Your Appeal Rights

Under ACA Section 2719, duplicate-therapy denials are adverse benefit determinations subject to internal appeal and independent external review for non-grandfathered plans. Under ERISA Section 503, employer-sponsored plans must offer full-and-fair review. File an internal appeal within 180 days of the denial. If the internal appeal is denied, request external review within four months of the final denial. Expedited review is available when delay would jeopardize health.

## Building a Strong Duplicate-Therapy Appeal

The core argument is that robotic gait training is not duplicative of conventional therapy — it is a distinct clinical intervention with different mechanisms, different indications, and different patient-selection criteria.

Documentation to assemble: - Prescribing physician or physiatrist letter that specifically addresses the duplicate-therapy rationale: explain the distinct mechanism of the robotic system, why the patient cannot achieve equivalent outcomes through conventional therapy alone, and what the expected functional goals are - Physical therapy or rehabilitation progress notes documenting the patient's current functional baseline and the specific deficits that conventional therapy has not resolved - Diagnosis documentation: the underlying condition (e.g., spinal cord injury, stroke, multiple sclerosis, acquired brain injury) and its current severity per the chart - Documentation of the specific robotic system prescribed and its clinical capabilities, obtained from the prescribing rehabilitation team

## Criteria-Mapping Structure

Obtain BCBS's coverage policy for robotic-assisted gait training and their duplicate-therapy policy. Review both. For each criterion: - Policy requirement: [copy verbatim from the BCBS policy] - Patient-specific evidence: [cite the chart finding, progress note, or prescriber statement that satisfies it]

Also request the BCBS medical policy's definition of "duplicate therapy" — and show specifically that the robotic intervention differs in mechanism, delivery, and outcome target from the conventional therapy already authorized.
