Coverage Criteria

Covered Indications

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 Medically Necessary Indications

Not medically necessary for indications other than cerebral palsy:

Other indications: Gait analysis is considered not medically necessary for all other indications due to insufficient peer-reviewed evidence of effectiveness.

Policy states insufficient peer-reviewed scientific literature demonstrates effectiveness; comprehensive analysis may be medically necessary only for surgical planning in children with cerebral palsy per clinical review.

Gait analysis for non‑cerebral palsy indications is considered not medically necessary because the peer‑reviewed scientific literature does not demonstrate effectiveness for those conditions. The policy notes that, outside cerebral palsy, evidence is insufficient to show that gait analysis improves health outcomes or utilization parameters, and therefore recommendations based on analysis have not been proven to benefit patients with other diagnoses.

Provider Actions & Billing Notes

Prior Authorization

Prior authorization is not required for gait analysis services.

Step Therapy

No step therapy requirements are specified for gait analysis; no prerequisite treatments or failed therapies are required prior to coverage consideration when the service meets medical necessity criteria.

Documentation Required

Documentation Requirement

Physician review and written report must accompany comprehensive motion analysis/EMG services (e.g., code 96004) documenting interpretation of the computer-based motion analysis, dynamic plantar pressure measurements, dynamic surface EMG, and dynamic fine-wire EMG as applicable.

Applicable code: 96004 — physician review and interpretation with written report

Denial Risk

Denial Risk for Non‑Cerebral Palsy Indications

Gait analysis (comprehensive motion analysis/EMG) is covered for the diagnosis of cerebral palsy. Claims for other indications may be denied as not medically necessary due to insufficient evidence.

Covered diagnosis: cerebral palsy
Non-covered/Not medically necessary: all other indications

Background

Laboratory‑based quantitative gait analysis is an assessment of coordinated muscle function that typically integrates video, kinematic and kinetic measurements, and electromyography (EMG) to evaluate walking. It has been proposed to aid surgical planning and rehabilitation, particularly in children with cerebral palsy; however, evidence of clinical benefit remains limited, and the effect of analysis‑driven treatment decisions on patient health outcomes has not been established.

Definitions

Kinematics — definition and brief description

DefinitionKinematics — movements of joints and limbs, including angular displacements, angular velocities and accelerations of limb segments, typically assessed using marker systems and multi-plane cameras to generate 3‑dimensional assessments.

Measurement methodsUses marker systems representing anatomic landmarks with cameras oriented in several planes; computer compiles movement data to assess joint and limb motion in 3 dimensions.

Common outputsRange and direction of joint motion isolated from simultaneous motions; graphic plots of joint and limb motion across gait phase (e.g., joint angles over the step cycle).

Kinetics — definition and brief description

DefinitionKinetics — factors that cause or control movement; applies principles of physics and biomechanics to observed kinematic patterns to describe forces generated during gait.

PurposeTranslates kinematic observations into analyses of forces to explain normal and abnormal movement patterns.

Role in gait analysisComplements kinematics by quantifying the mechanical causes of observed joint and limb motions to inform planning (e.g., surgical or rehabilitative).

EMG — definition and brief description of electromyography in gait analysis

DefinitionElectromyography (EMG) — measurement of timing and intensity of muscle contractions during walking, using surface or fine‑wire techniques to assess muscle activity relative to the gait cycle.

Measurement useEMG is recorded during walking to determine whether a muscle's activity is normal, out of phase, continuous, or otherwise altered across the step cycle.

Role in gait analysisProvides temporal and amplitude information about muscle activation that supplements video, kinematics, and kinetics for surgical planning and rehabilitation decisions, particularly in cerebral palsy.
