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.

Coverage Criteria

Mobile Standing Systems - Medical Necessity

Mobile standing systems (for non-ambulatory individuals) are covered when ALL of the following are met:

Mobile standing system coverage requirements: 1) There is a need to prevent or treat one or more of the listed medical complications: decubitus ulcer requiring off-loading that cannot be accomplished by other means; osteoporosis where improvement or stabilization of bone density cannot be achieved with other treatment or activities; compromised bowel/bladder function with demonstrated incomplete emptying or constipation refractory to other medical treatment; high potential for progressive contracture development (including but not limited to post-operative contracture release); or pulmonary complications with recurrent infections and poor clearance of pulmonary secretions despite other medical treatment.

Hip subluxation/dislocation: 2) Hip subluxation or dislocation is worsening and alternate treatments have not been successful.

Failure of current device or alternate treatment: 3) The individual is unable to accomplish the above goals with his/her current medical device/equipment or alternate medical treatment.

Plan of care: 4) There is a written plan of care.

PT evaluation and trial: 5) The individual has been evaluated in physical therapy with a trial using the standing device and has shown compliance, tolerance, and demonstrated potential for clinical benefit as determined by the evaluator.

Pediatric Gait Trainers - Medical Necessity

Gait trainers are covered when InterQual pediatric gait trainer criteria are met.

Pediatric gait trainer coverage: Coverage determined by InterQual CP: Durable Medical Equipment; Pediatric Gait Trainers — follow InterQual clinical coverage criteria for indications, functional status, and documentation.

The listing of a HCPCS or other billing code in this policy is for reference only and does not imply that the service described by the code is a covered benefit. Benefit coverage and payment are determined by applicable federal, state, or contractual requirements and other plan terms. The inclusion of a code in this policy does not guarantee reimbursement or claim payment, and other policies or guidelines may apply.

This policy is provided to assist in interpreting UnitedHealthcare standard benefit plans; however, federal, state, or contractual benefit plan requirements govern coverage and take precedence if there is any conflict with this policy. Before relying on this policy for a coverage decision, verify applicable federal, state, or contractual benefit plan terms. This document is informational and does not constitute medical advice.

Supported standing dosing — typical durations and frequencies

Typical session duration30 minutes per session is commonly referenced for positive impact on most outcomes (self-care, standing balance, ROM, cardio-respiratory, strength, spasticity, pain, skin, bladder and bowel function)

Typical weekly frequency5 times per week is the common dosing for most outcomes

Higher dosing for bone mineral density and mental function60 minutes per session, 4–6 times per week may be required for positive impact on bone mineral density (BMD) and mental function

Minimum standing definition used in evidencePositioned above 60° from horizontal for at least 10 minutes for a minimum of five sessions within a 2‑week period (definition used in systematic review)

Provider Actions & Requirements

Prior Authorization

Prior Authorization Required

Prior authorization is required — providers must obtain prior authorization using InterQual criteria for devices and services covered under this policy.

InterQual prior authorization required for initial requests and replacements when criteria apply

Billing Rule

Coding Inclusion Is Not a Guarantee of Payment

Document prior use or failure of alternate treatments when relevant to the request. Listing of a code in this policy does not guarantee coverage or payment; benefit terms and applicable federal, state, or contractual requirements govern coverage and reimbursement.

Inclusion of a code (e.g., E0637, E0638, E0641, E0642, E8000, E8001, E8002) is for reference only and is not a guarantee of payment

Background

Gait trainers and standing systems are mobility and positioning devices used to provide postural support and enable weight-bearing activities for children who cannot ambulate or stand independently. A gait trainer typically unweights the individual by using a rigid or flexible seat and provides trunk and pelvic stabilization with lateral and posterior supports to assist with ambulation. Standing systems (which may be static, multi-position, or mobile/dynamic) support the body in an upright position to promote weight bearing and may be integrated into or separate from mobility equipment.

These devices are prescribed to address clinical goals such as improving range of motion, helping prevent or manage contractures, supporting bone mineral density through weight bearing, assisting with postural clearance of secretions and pulmonary function, aiding bowel/bladder function, and reducing the risk of pressure injuries or progressive hip subluxation/dislocation. Evidence and guidance for dosing vary; clinical reports and reviews commonly reference regimens such as approximately 30 minutes, 5 times per week for many outcomes, with longer durations (for example, 60 minutes, 4–6 times per week) sometimes described for effects on bone mineral density and cognitive/mental function.

Definitions

Gait trainer — definition and key device features

Core definitionGait trainer: device that unweights an individual using a rigid or flexible seat, stabilizes or supports the trunk and pelvis with lateral and posterior components, and assists with ambulation

Seating and supportIncludes a rigid or flexible seat and trunk/pelvic stabilization (lateral and posterior components)

FunctionDesigned to unweight the user to facilitate practice of stepping and ambulation

Power optionsMay be mechanical (non‑powered) or electric (powered) depending on model and needs

Standing system — definition (static, dynamic, integrated)

Core definitionStanding system: either a separate device that requires transfer into it (e.g., tilt table or standing frame) or an integrated standing system on an individual’s mobility device (e.g., power standing system on a power wheelchair)
