Coverage Determination

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.

inv-01: Not Medically Necessary — SIT and AIT

Covered when ALL of the following are met:

Unproven therapies: Sensory integration therapy (SIT) and auditory integration training (AIT) are considered unproven and not medically necessary for treating any condition due to insufficient evidence of efficacy.

Claims for these therapies are subject to noncoverage determinations per this policy.

inv-02: Evidence-based coverage considerations

Evidence summary relevant to coverage decisions (synthesized from cited trials and guidelines):

ASI evidence: Small randomized trials and systematic reviews report positive effects of Ayres Sensory Integration (ASI) on individually generated goals (measured by Goal Attainment Scaling) and some impairment-level outcomes, but available studies are limited by small sample sizes, short-term follow-up, variable randomization/blinding, and heterogeneity of protocols.

Supports conditional consideration when delivered as part of occupational therapy with documented individualized goals.

Sensory-based interventions: Classroom sensory-based single-sensory strategies (for example, weighted vests or therapy balls) show inconsistent or insufficient evidence; AOTA specifically does not recommend weighted vests due to ineffectiveness and/or potential harm.

May warrant noncoverage or restriction; documentation of rationale and embedding within broader therapy recommended.

Auditory integration training (AIT): Systematic reviews and authoritative guideline bodies conclude auditory integration–based approaches do not improve language outcomes (low strength of evidence), are considered investigational by professional organizations, and NICE recommends that AIT should not be used for speech and language problems in children and young people with autism. Safety concerns (distress, potential hearing risk) have been noted in the literature.

AIT is considered investigational / not medically necessary pending robust supportive evidence.

There are no additional condition-specific exclusions listed in this policy beyond the central coverage determination. The policy explicitly states that Sensory integration therapy (SIT) and Auditory integration training (AIT) are unproven and not medically necessary for treating any condition due to insufficient evidence of efficacy.

Professional guidance and position statements cited in the evidence base discourage use of auditory integration approaches. The National Institute for Health and Care Excellence (NICE) advises that auditory integration training should not be used to manage speech and language problems in children and young people with autism, and the American Academy of Audiology (AAA) has concluded that AIT is investigational and requires prospective, systematic research to demonstrate efficacy.

This Medical Policy is provided for informational purposes to assist interpretation of UnitedHealthcare standard benefit plans. Coverage determinations must reference the member-specific benefit plan document, which governs in the event of any conflict. Before applying this policy for prior authorization or coverage decisions, verify any applicable federal or state mandates; the policy itself does not constitute medical advice.

Based on available evidence and authoritative reviews, the policy finds that SIT and AIT are unproven and not medically necessary for treating any condition. Systematic reviews and randomized trials provide limited or low-strength evidence for benefit, and several guideline and professional statements discourage or classify AIT as investigational. Claims for these services are therefore subject to noncoverage determinations under this policy.

Auditory integration approaches have a low strength of evidence for improving language or speech outcomes. AHRQ and subsequent reviews summarize small, heterogeneous trials with limited effect, NICE explicitly recommends against using AIT for speech and language problems in children with autism, and the AAA regards AIT as investigational—additionally noting potential safety concerns such as distress or hearing-related risks in some sound-based interventions.

Coverage determination

The following are unproven and not medically necessary due to insufficient evidence of efficacy: Sensory integration therapy (SIT) and Auditory integration training (AIT). Use this when assessing medical necessity and coverage.

Sensory integration therapy (SIT) — unproven / not medically necessary
Auditory integration training (AIT) — unproven / not medically necessary

Note

FDA / Regulatory note

The equipment commonly used for sensory integration therapy and auditory integration training is not considered medical and is not regulated by the U.S. Food and Drug Administration (FDA). FDA approval alone is not a basis for coverage; equipment status is informational only.

Equipment for SIT/AIT is not considered medical and is not FDA-regulated
FDA/regulatory status is informational and does not determine coverage

Prior Authorization

Verify plan and mandates before prior authorization

Before submitting prior authorization requests or rendering services, verify the member-specific benefit plan and any applicable federal or state mandates. In the event of conflict, the member-specific benefit plan governs. Check for prior authorization requirements and any state or federal coverage mandates that could affect coverage.

Documentation Required

Coding reference and documentation note

Coding listed here is provided for reference and does not guarantee coverage or reimbursement. Document services thoroughly; include assessment, individualized goals, therapy content, time-based units, and clinical rationale. Inclusion of a code in this policy is not a determination of coverage.

97533 — Sensory integrative techniques to enhance sensory processing and promote adaptive responses, direct (one-on-one), each 15 minutes
Listing of a code does not imply coverage or payment; verify member benefits

Documentation Required

Document individualized goals and GAS

When sensory integration interventions are used, document individualized, measurable treatment goals and use Goal Attainment Scaling (GAS) where appropriate per AOTA recommendations. Record baseline function, targeted outcomes, progress toward goals, and frequency/duration of services.

Key Terms

Sensory Integration Therapy (SIT) definition

TermSensory Integration Therapy (SIT)

DefinitionTherapy provided by an occupational therapist that combines vestibular, proprioceptive, and tactile stimulation during individual 60–90 minute sessions to elicit adaptive motor responses and improve perception and sensorimotor skills.

Typical methodsUse of textured mitts, carpets, scooter boards, ramps, swings, bounce pads, suspended equipment, weighted vests and blankets to encourage noncognitive, creative, explorative activity.

Dose/frequencyUsually 1–3 sessions per week over several months to a few years.

Intended outcomesImproved sensorimotor skills, behavior, and academic performance (theoretical).

Auditory Integration Training (AIT) definition

TermAuditory Integration Training (AIT)

DefinitionA protocol (e.g., Berard AIT) developed to address abnormal sound sensitivity that requires listening to modulated music via a specific device and high-quality headphones for a total of about 10 hours over 10–12 consecutive days under supervision of a trained practitioner.

Evidence notesPublished literature is limited, protocols unstandardized, older RCTs inconsistent; safety concerns include distress and potential hearing damage.

Typical populationsIndividuals with behavioral disorders or autism spectrum disorders (ASD).

ASI / SIT definition and notes

TermAyres Sensory Integration (ASI) / Sensory Integration Therapy (SIT)

Core descriptionIndividualized, clinic-based occupational therapy approach using sensory-motor activities (vestibular, proprioceptive, tactile) to improve functional outcomes and adaptive responses.

Evidence summarySmall RCTs report positive effects on Goal Attainment Scaling; overall evidence limited by small sample sizes, lack of blinded evaluation, short-term follow-up, and heterogeneity of protocols.

AOTA guidanceAOTA identifies ASI for individualized goal areas with measurement by Goal Attainment Scaling (B-moderate evidence) but rates several sensory strategies as insufficient or not recommended (e.g., weighted vests D-not recommended).

Auditory Integration Training (AIT/TOMATIS) — sound-based interventions

TermAuditory Integration Training (AIT) / TOMATIS (sound-based interventions)

DescriptionSound-based interventions (Berard AIT, TOMATIS) aiming to modify auditory processing using modulated or filtered music protocols; protocols are heterogeneous and not standardized.

Evidence and safetyLimited and inconsistent evidence from small/uncontrolled studies and some RCTs; reported safety concerns include distress and potential hearing damage; further confirmatory studies needed.

Recent studiesRecent trials (e.g., TOMATIS cross-sectional/longitudinal studies) report some positive findings but have limitations and require independent confirmation.

Sensory Integration Therapy / Ayres Sensory Integration summary

ApproachAyres Sensory Integration and other sensory-based interventions employ therapist-led sensory-motor activities to elicit adaptive responses and improve occupational performance.

Common techniquesTherapist-provided vestibular, proprioceptive, and tactile stimulation using equipment such as swings, scooter boards, ramps, and weighted items.

Evidence contextMultiple systematic reviews and small RCTs exist; some trials show improvements on Goal Attainment Scaling, but overall evidence is limited by small samples, heterogeneity, and short follow-up.

Clinical deliveryTypically delivered by occupational therapists in individualized sessions lasting 60–90 minutes, often 1–3 times weekly over months to years.
