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 and Documentation Conditions

inv-01: Documentation as condition of coverage

Covered when ALL of the following documentation elements are present

Documentation elements: Prior authorization obtained if required; clinical documentation reviewed and updated at regular intervals and includes signature and printed names of the member/enrollee, legal guardian, rendering clinician/technician, and supervising practitioner/Qualified Healthcare Provider as applicable; documentation and data collection support that active treatment was delivered throughout billed services (continuous and efficient use of session time clinically justified and full session duration consisted of active treatment with minimal nonprogrammed or idle time); service activity notes completed prior to claim submission including identification (provider organization and rendering provider/technician, member name, DOB or unique identifier), exact date and start/end times, date of note creation with rationale if different, pauses in services with times, location of services, type of service with applicable code, signature of qualified rendering provider/technician; detailed summary of treatment activity including current clinical status and presenting symptoms, primary target areas, techniques used, direct treatment provided, barriers to implementation and mitigation, protocol modification details when applicable (list of modifications or rationale that none were needed, frequency and duration thresholds, required one-on-one review), direction of technician and direct observation when applicable, caregiver training participation and barriers when provided, telehealth compliance (HIPAA-compliant platform and rendering provider/technician camera/audio confirmation), progress toward goals with cumulative data and baseline as applicable, member response and outcome of interventions, identification of all participants and relationships, coordination of care; addenda reference the original note, include date of completion, and legible name/signature/credentials; discharge planning and discharge summary elements (referrals, rationale, signatures, discharge date) as applicable.

Examples of activities that do NOT constitute active session engagement are unstructured or non-therapeutic periods and tasks that do not provide documented, goal-directed intervention. These include, but are not limited to, meals not embedded with documented teaching, free play that is not embedded with documented teaching or data collection, administrative tasks, and documentation completed outside of direct intervention. Periods without documented data collection or therapeutic interaction addressing specific goals should be excluded from billed direct treatment time.

When this policy conflicts with state Medicaid coverage provisions, the applicable state Medicaid rules and manuals take precedence. Providers must follow the member’s coverage documents and relevant state or federal requirements in cases of discrepancy.

All billed units for 97153/97154 across the entire six-month authorization period that are not supported by the protocol modification requirements in section I.D.8.f. are subject to payment denial or recoupment. The policy gives the example that insufficient protocol modification proportion (e.g., 7% when higher is required) for the authorization period may trigger denial/recoupment of the unsupported units.

Authorization-period implication

Provider Responsibilities, Documentation, and Billing Risks

Prior Authorization

Prior Authorization Required

Prior authorization approval for ABA services must be obtained when required by the member's plan before services are billed. Verify whether the member's benefit plan requires prior authorization and obtain written/ electronic approval prior to rendering covered services.

Affected codes: ABA services (e.g., 0373T, 97153, 97154, 97155, 97156, 97157, H0031, H0032).
Confirm authorization timeframes and units against the member's plan documents.

Note

Verify Coverage and Authorization Against Plan Documents

Providers must verify coverage, benefits, and any authorization requirements against the member's specific plan documents before delivering or billing services. Coverage decisions remain subject to the health plan's evidence of coverage, policy terms, exclusions, limitations, and applicable state/federal requirements.

Check the member's certificate of coverage / evidence of coverage for ABA benefit limits, prior authorization triggers, and service definitions.

Background and Purpose

Applied Behavior Analysis (ABA) documentation is required to demonstrate medical necessity, active treatment, and measurable progress toward individualized goals. Core ABA characteristics include objective assessment and measurement, understanding behavior in context and its social value, promotion of dignity, and application of behavior-analytic principles to improve health, skills, and independence. Essential practice elements include comprehensive baseline assessment and ongoing objective data collection, environment design and modification, consistent case supervision by a behavior analyst, direct observational measurement to inform treatment decisions, stakeholder and caregiver collaboration, and documented caregiver training and supervision. Documentation should show continuous, efficient use of session time with data demonstrating progress toward targets.

Definitions and Referenced Materials

Definition — 97155

Code and short definition97155 — Adaptive behavior treatment with protocol modification, administered by a physician or other qualified health care professional; may include simultaneous direction of technician, face-to-face with one patient, each 15 minutes.

Role of 97155May be used to demonstrate new or modified protocol to a technician with the member/enrollee present; technician-only supervision or team meetings do not constitute protocol modification.

Protocol-modification requirement linkageWhen 97155 is rendered, documentation must list protocol modifications (or rationale for no modifications), and meet the protocol modification time/percentage thresholds.

Definition — 97153 / 97154

97153 definition97153 — Adaptive behavior treatment by protocol, administered by technician under the direction of a physician or other qualified health care professional, face-to-face with one patient, each 15 minutes.

Core ABA Practice Elements

inv-19: Core ABA practice elements

Core ABA characteristics and essential practice elements per CASP/BHCOE

Core characteristics: Objective assessment and measurement; understanding behavioral context and the behavior's value to the person and supports; promotion of the person’s dignity; utilization of behavior-analytic principles and procedures to improve health, skills, independence, quality of life, and autonomy; consistent, ongoing objective data analysis to inform clinical decision making.

Essential practice elements: Comprehensive baseline assessment describing specific behavior levels; collaboration with the person/guardians and support network to develop meaningful goals; focus on small, measurable behaviors that build toward larger skills; direct observational data collection, quantification, and analysis to guide treatment; design and management of environments to minimize challenging behavior and maximize progress; function-based treatment for challenging behavior linking function to interventions; individualized, detailed behavior‑analytic treatment plans using reinforcement and established behavioral principles; repeated, frequent, and consistent implementation of treatment protocols until discharge criteria are met; frequent analysis and adjustment of the treatment plan based on progress; direct training of caregivers and other involved laypersons and professionals; comprehensive supervision infrastructure by a behavior analyst for assessments and treatment.

Treatment Modalities and Telehealth

inv-20: Telehealth ABA

Telehealth requirements: If services are delivered via telehealth, the platform must comply with HIPAA privacy and security standards and the rendering provider/technician must have the camera turned on and functioning audio output/input.
