Coverage Criteria

Trek Health ingests and normalizes Transparency in Coverage data and payer policy updates to give provider organizations a clear view of how commercial reimbursement behaves across markets, payers, and services. Our platform transforms raw payer disclosures into structured intelligence that supports contract evaluation, payer negotiations, and service line strategy. By combining market benchmarks with ongoing policy visibility, Trek helps teams identify variability, risk, and opportunity in commercial reimbursement. The result is faster insight, stronger negotiating positions, and more informed financial decisions.

Not covered / Not medically necessary

Not covered / Not medically necessary when ANY of the following apply

Non-cerebral palsy indications: Gait analysis performed for indications other than cerebral palsy is considered not covered (Medicare Advantage) or not medically necessary (Commercial Products) because evidence is insufficient to determine effects on health outcomes.

Policy states lack of proven efficacy and insufficient evidence for other indications.

Prior authorization is not applicable for this service.

Note

Gait analysis is covered for members with a diagnosis of cerebral palsy. For other indications, coverage differs by product: for Medicare Advantage plans it is considered not covered; for Commercial products it is considered not medically necessary when performed for indications other than cerebral palsy.

Denial Risk

Denial Risk for Non‑Cerebral Palsy Indications

When gait analysis is performed for indications other than cerebral palsy, the service may be denied (Medicare Advantage: not covered; Commercial: not medically necessary).

Background

Gait analysis is a quantitative laboratory assessment of coordinated muscle function that typically requires a dedicated facility and specialized staff. Comprehensive assessments often include video recording, three‑dimensional kinematics and kinetics, and may include electromyography (EMG) and plantar pressure measurements to evaluate movement patterns and forces during walking.

The policy notes that while gait analysis can influence surgical and treatment planning—particularly in children with cerebral palsy—evidence demonstrating improved health outcomes is limited. For cerebral palsy cases, comprehensive gait analysis may be considered medically necessary for preoperative planning; for most other indications, efficacy has not been proven.

Definitions

Definition of gait analysis — key aspects

DefinitionGait analysis is the quantitative laboratory assessment of coordinated muscle function, typically involving video-recorded observation of a patient walking and requiring a dedicated facility and specialized staff.

Key componentsVideo-recorded observation from multiple planes with slow-motion review to detect movements not seen at normal speed; computerized compilation of movement data for quantitative assessment.

3D kinematicsMarker-based systems and multi-camera capture are used to visualize anatomic landmarks and assess joint and limb motion in three dimensions.

KineticsUse of physics and biomechanical principles to analyze forces that cause or control movement and to explain observed kinematic patterns.

Electromyography (EMG)Dynamic EMG during walking measures timing and intensity of muscle contractions to determine normality, phase, continuity, or clonic activity.

Specialized staff and facilitiesTypically requires a dedicated laboratory setting with trained personnel to conduct, process, and interpret comprehensive gait analysis data.

Definition of kinematics and kinetics

Kinematics — definitionDescribes movements of joints and limbs, including angular displacement, velocities, and accelerations; uses marker systems and multi-plane camera data to assess motion in three dimensions.

Kinematic outputsMeasures include joint angles, angular velocities/accelerations, and time–distance variables such as step length, stride length, cadence, and cycle time.

Kinetics — definitionDescribes the factors (forces) that cause or control movement; evaluates forces using principles of physics and biomechanics to explain kinematic patterns.

Kinetic analysis useGenerates analyses that describe forces generated during normal and abnormal gait to inform interpretation of motion data.
