Coverage Determinations

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

Covered when ALL of the following are met:

Not medically necessary for treatment of autism, intellectual disability, or learning disabilities: Sensory integration therapy and auditory integration therapy are considered not medically necessary as the evidence is insufficient to determine effects on health outcomes for children and adults with autism, mental retardation, or learning disabilities.

Supported by AAP statement noting limited and inconclusive research for SIT and Cochrane review finding no meaningful clinical improvements for AIT.

Benefits may vary between groups and contracts. Refer to the member's Benefit Booklet, Evidence of Coverage, or Subscriber Agreement for information about services that may be non‑covered or subject to different benefit provisions.

This policy addresses coverage determinations for sensory integration therapy (SIT) and auditory integration therapy (AIT) when used to treat children and adults with developmental disorders, including autism spectrum disorder, intellectual disability (mental retardation), and learning disabilities. These interventions are evaluated for Blue Cross Blue Shield of Rhode Island members and the policy specifies the coverage stance for the therapies and any procedure codes explicitly considered not medically necessary.

Billing Rule

Member Benefits and Billing

Verify member benefits, eligibility, and plan-specific coverage before providing services. Benefits and eligibility are determined by the member's subscriber agreement, member certificate, and/or the employer agreement; those documents supersede this medical policy. For member-specific benefit questions, contact the provider call center. If services are determined to be not medically necessary or are non-covered benefits, providers may not bill the member unless the member was informed and provided written agreement in advance to continue treatment at their own expense. Refer to participation agreements for applicable provisions.

Contact provider call center for member-specific benefits and eligibility.
Do not bill members for services deemed not medically necessary unless prior written consent obtained.
Member subscriber agreement and employer agreement supersede this policy.

Denial Risk

Claims Handling

For BlueCHiP for Medicare and Commercial Products: Sensory integration therapy (SIT) and auditory integration therapy (AIT) for autism, intellectual disability (mental retardation), or learning disabilities are considered not medically necessary. The following CPT code is considered not medically necessary and should not be billed as payable: 97533 — Sensory integrative techniques to enhance sensory processing and promote adaptive responses to environmental demands, direct (one-on-one) patient contact by the provider, each 15 minutes. Claims for these services should be denied as not medically necessary per this policy; follow standard claim denial and member notification procedures.

Do not bill CPT 97533 for SIT/AIT; it is considered not medically necessary.
Follow standard claims denial processes and member notification when services are non-covered.

Background

Sensory integration therapy (SIT) aims to improve the way the brain processes and adapts to sensory inputs (vestibular, proprioceptive, tactile) rather than teaching discrete skills; it is typically delivered one‑on‑one by specially trained occupational therapists and sessions may continue for extended periods. Auditory integration therapy (AIT) encompasses approaches (also called AI training, auditory enhancement training, audio‑psychophonology) that use graded exposure to modified or filtered sound—examples include the Berard and Tomatis methods—to reduce hypersensitivity to particular frequencies through repeated listening sessions. Systematic reviews, including a Cochrane review for AIT in autism, have not demonstrated meaningful clinical improvements; therefore these therapies are considered not medically necessary for treatment of autism spectrum disorder, intellectual disability, or learning disabilities.

Definitions

Sensory integration therapy (SIT) — definition, delivery, duration

DefinitionTherapy using activities that provide vestibular, proprioceptive, and tactile stimuli selected to match specific sensory processing deficits; aims to improve how the brain processes and adapts to sensory information rather than teaching discrete skills.

Typical delivery formatOne-on-one sessions delivered by occupational therapists with specialized training in sensory integration theory and techniques.

Typical durationOften provided as part of a comprehensive occupational therapy program and may continue for more than 1 year.

Auditory integration therapy (AIT) — definition and examples

DefinitionTherapies that use modified or filtered sound/music and graded exposure to sounds (e.g., removal of frequencies to which an individual is hypersensitive) to reduce auditory hypersensitivity.

Common methods / examplesBerard method (two 30-minute sessions per day over 10 consecutive days), Tomatis method (electronically-modified music and speech), Samonas Sound Therapy (filtered music, voices, nature sounds).

Clinical evidence summaryMost evidence is in autism; systematic reviews (including a 2011 Cochrane review) generally failed to demonstrate meaningful clinical improvements, and AIT is considered not medically necessary due to lack of proven efficacy.
