Evaluation currency window

Evaluation currency windowEvaluation or re-evaluation is considered current when performed within 60 days prior to the start of care date or within 60 days before the end of the current authorization period.

Authorization validity for initial evaluationAuthorization for the initial ABA evaluation (97151) is valid for 60 days from the requested evaluation date.

Timing for re-evaluation submissionsA re-evaluation may occur as early as 60 days prior to the end of the current authorization period and is current if performed within 60 days before that end date.

Attendance threshold

Attendance threshold for continued authorization>= 85% attendance required for the child or youth and for parent/caregiver participation (attendance logs must include calculation of percent attended).

Documentation when attendance below thresholdIf attendance falls below 85% without supporting documentation, continuation at previously approved frequency requires physician review and may be denied.

Use in extensions/recertificationAttendance logs with percentage attended are required for 90-day extensions and 180-day recertifications.

15-minute billing rounding

15-minute billing rounding ruleConvert total daily billable minutes to units by dividing by 15; partial units of 7 minutes or fewer = 0 units; partial units >7 minutes round up to 1 unit.

Daily aggregation methodCount total billable minutes for the calendar day for the client, then divide by 15 to compute billable units of service.

Example providedExample: 68 total billable minutes/15 = 4 units + 8 minutes; 8 minutes >7 so converted to 1 unit; total = 5 units of service.

97151 authorization limit

97151 authorization limitProcedure code 97151 will be authorized for up to 24 units (six hours) for initial evaluations and for re-evaluations on subsequent authorizations.

Timeframe for use97151 must be used within 30 calendar days of the first date of service for that code and is not reimbursable unless the evaluation was submitted for authorization.

Re-evaluation frequency97151 is intended for initial evaluations and re-evaluations by the LBA once every 180 days (and authorized up to 24 units each authorization).

Daily direct treatment cap

Daily direct treatment capDirect treatment for the child or youth is limited to a total of 8 hours per day, inclusive of procedure codes 97153, 97154, 97155, and 97158.

Applies to individual and group codesThe 8-hour per day cap applies across direct individual (97153, 97155) and group (97154, 97158) ABA treatment codes.

Exceptions for clinical needFor clients 20 years old and younger, limitations may be exceeded with evidence of medical necessity.

Provider Responsibilities, Authorization, and Documentation

Prior Authorization

Prior Authorization Required

Prior authorization is required for an ABA initial evaluation (procedure code 97151), an initial course of ABA treatment, and subsequent recertifications for treatment (procedure codes 97153, 97154, 97155, 97156, 97158). Re-evaluations (97151) for recertification require authorization. Requests may be submitted via mail, fax, or electronic portal; electronic signatures must comply with applicable federal and state statutes and include an electronic date on the same page as the signature. All authorization requests must include the completed CCP Prior Authorization Request form and submitter certification.

Affected codes: 97151, 97153, 97154, 97155, 97156, 97158
Submission channels: TMHP Prior Authorization Department via mail, fax, or electronic portal
Electronic signature requirements: date on same page; certification of compliance

Denial Risk

Late Signature Denies Prior Dates

When the CCP Prior Authorization Request Form (or other required authorization documentation) is signed and dated after the requested evaluation date, dates of service prior to the prescribing provider's signature date will be denied. Similarly, when a PA request is submitted after the requested evaluation date, dates of service prior to the received date may be denied.

Prescribing provider signature must be within 60 days prior to or on the anticipated evaluation date for initial evaluation PA requests
Authorization for initial ABA evaluation (97151) is valid for 60 days from the requested evaluation date

Denial Risk

Late Recertification Denial Risk

Recertification requests submitted after the current authorization end date are denied for all dates of service prior to the date the request is received (for 90-day extensions and for 180-day recertification requests). A 90-day recertification is timely when submitted within 30 days prior to the end of the current authorization period; a 180-day recertification request must be received no earlier than 60 days before the current authorization period expires. Gaps in service of 180 days or more require submission as an initial request with full initial documentation.

90-day recertification: submit within 30 days before current authorization end date
180-day recertification: complete request no earlier than 60 days before expiration
Requests after authorization end date are denied for prior dates; gaps >=180 days treated as initial requests

Documentation Required

Required Documentation for Initial Authorization

Initial authorization requests must include comprehensive diagnostic documentation and specific referral elements. For an ABA initial evaluation authorization, submit a completed CCP Prior Authorization Request Form signed and dated by a prescribing provider within 60 days prior to or on the anticipated evaluation date, and documentation of a comprehensive diagnostic assessment or reconfirmation of ASD diagnosis signed and dated by the diagnosing physician dated within 3 years prior to the PA request receipt.

Referral must include age and year of initial ASD diagnosis, co-morbid conditions, DSM symptom severity, and standardized diagnostic assessment documentation within 3 years
CCP Prior Authorization Request Form must be signed by the prescribing provider within 60 days prior to or on the requested evaluation date
Initial 97151 authorization valid for 60 days from requested evaluation date

Documentation Required

Re-evaluation and Recertification Documentation

Re-evaluation and recertification requests must include a current ABA re-evaluation and updated treatment plan (signed and dated by the LBA), baseline/current/interim data across settings, attendance logs and progress summaries as applicable, and a completed CCP Prior Authorization Request Form signed by the prescribing provider within required timeframes. Re-evaluations are considered current when performed within 60 days prior to the end of the authorization period; re-evaluation documentation will be reviewed upon submission for authorization.

ABA re-evaluation components: updated BSP if applicable; baseline, current, and interim data demonstrating progress across at least two settings; standardized assessment results; discharge/fading plan
Attendance logs must calculate % of authorized sessions attended by child and by parent/caregiver; attendance <85% requires additional justification
Progress summary (97155) must be submitted after first 90 days and signed by LBA; recertification requests submitted >60 and <=180 days after evaluation require progress summary; >180 days require a new re-evaluation

Definitions and Key Terms

Applied Behavior Analysis (ABA) definition and LBA role

Applied Behavior Analysis (ABA)The application of evidence-based behavior-analytic principles by a trained provider (e.g., Licensed Behavior Analyst) to produce meaningful, durable, generalized changes in socially significant behaviors; Intensive Behavioral Intervention (IBI) denotes high-intensity ABA.

Licensed Behavior Analyst (LBA) roleLBAs conduct initial evaluations and re-evaluations (97151), develop treatment plans, may delegate parent training to licensed assistant behavior analysts (LaBAs), and must ensure supervision and documentation standards are met.

Scope and intentABA focuses on treating behavior difficulties and shaping behavior patterns through environmental adaptations and consistent reinforcement across settings to achieve durable, generalized outcomes.

Eligibility age

Eligibility age for autism servicesAutism services under the Texas Health Steps-Comprehensive Care Program are a benefit for Medicaid children and youth 20 years old and younger (age <= 20 years).

Age referenced in intensity criteriaIntensity categories reference age thresholds (e.g., high frequency often considered for age <=6; moderate for <=12), but overall eligibility remains <=20 years.

Exceptions for medical necessityFor clients 20 years old and younger, limitations may be exceeded with evidence of medical necessity.

Intensity categories

Intensity categories definedHigh (IBI) >20 hrs/week; Moderate 6–20 hrs/week; Targeted/focused up to 5 hrs/week or 20 hrs/month; Maintenance/consultative 2–4 hrs/week or less.

Eligibility criteria per categoryEach category requires documentation showing specified criteria (age, DSM severity level, target behaviors severity, time since initiating ABA) to justify the requested intensity.

Review of requests exceeding guidelinesTreatment plans requesting frequency above these guidelines are sent for physician review to determine medical necessity.
