# Texas Medicaid ABA coverage: the intake guide.

_Payer Guide · Texas Medicaid · Last updated September 2026 · 13 primary sources_

> THSteps-CCP EPSDT ages 0–20; PA on everything, 90/90/180 cadence, 3-yr dx recency.

Texas Medicaid added ABA as a defined benefit on February 1, 2022 — "Autism Services" under the Texas Health Steps Comprehensive Care Program (THSteps-CCP), the state's EPSDT vehicle. It is one statewide rulebook: HHSC writes the medical-necessity criteria into the Texas Medicaid Provider Procedures Manual (TMPPM), and every delivery channel — fee-for-service through TMHP and all the STAR, STAR Kids, and STAR Health managed-care plans — applies the same criteria. The benefit covers ages birth through 20 (eligibility ends on the 21st birthday; CHIP is explicitly excluded), requires prior authorization on everything from the initial evaluation forward, and runs on a distinctive 90/90/180-day authorization cadence. The MCO guides below cover per-plan submission mechanics; the clinical rules on this page apply everywhere.

## Prior authorization and diagnosis at a glance

- **Prior auth for the assessment**: Required — CCP PA form with signed prescriber referral + ASD dx (made/reconfirmed within 3 years); 97151 capped at 24 units [2]
- **Prior auth for treatment**: Required — two 90-day initial periods, then 180-day recerts; since 4/1/2025 no prescriber signature on the 90-day extension [2][3]
- **Autism diagnosis required?**: Yes — ASD (F84.0); diagnosis alone doesn't establish medical necessity [2]

## At a glance

- **Covers ABA?:** Yes — ages birth through 20, via THSteps-CCP (EPSDT); CHIP excluded
- **Assessment auth:** Required — 97151 (24 units / 6 hrs max), CCP PA form + signed prescriber referral
- **Treatment auth:** Required — 90-day initial + 90-day extension, then 180-day recertifications
- **Diagnosis recency:** ASD dx (DSM criteria + severity level) made or reconfirmed within the past 3 years
- **Rates (per 15 min):** 97153: $14.50 · 97151: $27.56 · 97155: $20.08–$25.10 (eff. 9/1/2025, ~11.5% increase)
- **Daily cap:** 8 hours (32 units) of direct treatment across 97153, 97154, 97155, 97158
- **Delivery:** FFS via TMHP + STAR / STAR Kids / STAR Health MCOs — identical TMPPM criteria
- **Staff screening:** BTs need RBT, BCAT, or ABAT cert (no Medicaid enrollment); monthly LEIE + HHSC-OIG exclusion checks on all staff

## The benefit and who qualifies

Autism Services is an EPSDT benefit: THSteps-CCP covers medically necessary ABA for members from birth through age 20, with eligibility ending on the 21st birthday. The gate is an ASD diagnosis — but not any diagnosis, from anyone, at any time. The TMPPM requires the diagnosis to come from a developmental pediatrician, neurologist, psychiatrist, licensed psychologist, or an interdisciplinary team (a physician, PA, or NP in consultation with qualified child specialists with autism expertise), documented with DSM diagnostic criteria and a symptom severity level, and made or reconfirmed within the 3 years before the PA request. A diagnosis alone is not sufficient to establish medical necessity — the evaluation builds that case. For intake, the 3-year recency rule is the trap to screen for early: a child diagnosed at 2 who shows up at 7 needs a diagnostic reconfirmation before the PA can go in. [1][2]

## The authorization cadence: eval → 90 → 90 → 180

Everything is prior-authorized. The ABA evaluation (97151, limited to 24 units / 6 hours per evaluation, billed with the HO modifier by the LBA) needs a PA that includes a signed referral from the prescribing provider plus the diagnosis documentation, submitted on the CCP Prior Authorization Request Form. Treatment then authorizes in two consecutive 90-day periods — the initial 180-day treatment plan must be signed and dated by the prescribing provider — followed by recertifications in increments of up to 180 days. [2][3]

The friction-reducer worth knowing: effective April 1, 2025, TMHP dropped the prescribing-provider signature requirement on the CCP PA form for the 90-day treatment extension. The initial plan still needs the prescriber's signature, but the mid-cycle extension no longer stalls on chasing a physician's pen — a real cycle-time win for practices that learned the benefit in its first three years. [2][3]

## Rates, modifiers, and who can enroll

HHSC raised ABA rates roughly 11.5% across the board effective September 1, 2025 — the first adjustment since the benefit launched. Per 15-minute unit: 97151 evaluation pays $27.56 (was $24.71); 97153 direct treatment by a behavior technician pays $14.50 (was $13.00); 97155 protocol modification pays $20.08–$25.10 and 97156 family training $18.40–$23.01, tiered by credential modifier. Texas flags credentials with modifiers — HO for the Licensed Behavior Analyst (LBA), HN for the Licensed assistant Behavior Analyst (LaBA), HM for behavior technicians — though 97153 itself takes no credential modifier. Two structural notes: only LBAs can enroll in Texas Medicaid (LaBAs and BTs bill under the LBA's supervision), and MCO reimbursement is contract-specific even though it generally tracks the HHSC fee schedule. The rate figures here come from the HHSC rate-hearing packet; confirm current values in the TMHP Online Fee Lookup before building revenue models. [4][5]

## Delivery rules: hour caps, telehealth, and the MCO landscape

Direct treatment is capped at 8 hours (32 units) per day combined across 97153, 97154, 97155, and 97158. Telehealth (synchronous audio-visual, modifier 95) is allowed for 97151, 97155, 97156, 97158, and 99366 — but 1:1 direct treatment delivered by a BT or LaBA must be in person; no telehealth. Interdisciplinary team meetings are billable under 99366 with an ABA PA on file. [2][13][1]

On the delivery side, Texas runs a hybrid: fee-for-service through TMHP, and managed care through STAR (most children), STAR Kids (disability-related Medicaid), and STAR Health (foster care, statewide through Superior). Texas has 15+ Medicaid MCOs across its service delivery areas — including BCBSTX, Community Health Choice, Cook Children's, El Paso Health, and Parkland alongside the plans profiled below — and all of them apply the same TMPPM criteria. What varies per plan is the PA intake machinery: forms, portals, fax lines. Capture the child's plan at intake and use the matching MCO guide. HHSC's January 2026 service-area roster confirms the per-plan footprints throughout this section are still current — e.g., Harris County STAR runs through Community Health Choice, Molina, Texas Children's, United, and Wellpoint; Bexar STAR through Aetna, Community First, Superior, and Wellpoint — superseding the September 2024 archived copy this directory previously rested on. [2][13][1]

## Staffing & credentialing: who you can hire, and what they must clear

Texas certifies behavior technicians but doesn't license them. The TMPPM (§ 2.3.6.3) requires every BT to hold one of three certifications — RBT, BCAT, or ABAT — so the RBT is accepted but explicitly not the only pathway. BTs may not enroll in Texas Medicaid (they render under the enrolled LBA), may not use "therapist" in their job title when interacting with Medicaid families, and may not conduct assessments or modify the treatment plan. There's no state license, registry, or training-hour add-on for BTs: Occupations Code § 506.054 exempts a person designated as a behavior technician from behavior analyst licensure when working under the authority and direction of an LBA or LaBA, so the certification requirement comes from Medicaid policy, not licensure law. For the RBT pathway, the BACB's own floor is what screens your hires: 18+, high-school education, a criminal background check and abuse-registry check no more than 180 days before applying, the 40-hour training, a competency assessment, and the exam. [2][6][7][8][9][10][11][12]

The agency-level screening that actually binds a standalone ABA practice is exclusion screening, not the long-term-care registries. As a condition of enrollment, all providers must screen every employee and contractor every month against both the federal HHS-OIG LEIE and the Texas HHSC-OIG exclusion list (TMPPM Vol. 1, § 1.3.1) — build this into payroll-cycle compliance, not just onboarding. The Employee Misconduct Registry, by contrast, applies only to the facility types listed in Health & Safety Code § 253.001 (nursing facilities, HCSSAs, assisted living, ICF/IID, and similar) — a standalone ABA agency isn't on that list, so EMR pre-hire checks aren't legally required unless you also hold one of those licenses. Fingerprinting is similarly narrow: it attaches at provider enrollment, only for high categorical-risk providers and owners with a 5%+ interest (via IdentoGO, with proof uploaded to PEMS within 30 days of application) — individually licensed behavior analysts are not designated high-risk. At the supervisor level, TDLR requires every LBA and LaBA applicant to pass a criminal history background check as a condition of licensure. [2][6][7][8][9][10][11][12]

Supervision structure follows enrollment structure. Only the LBA enrolls and bills; the LBA must directly employ or contract with every LaBA and BT on the team, and LaBAs can't practice independently — by statute they must be supervised by an LBA per their certifying body's requirements. The TMPPM makes LBAs the direct supervisors of LaBAs and BTs but sets no numeric ratio of its own, deferring to certifying-body minimums — which makes the BACB standard the operative floor for RBT-credentialed staff: supervision of at least 5% of service hours each month, with at least two face-to-face contacts per month (one observing service delivery, one individual). One billing wrinkle to plan around: only direct supervision — the LBA observing the LaBA or BT with the client — is reimbursable, under 97155; indirect supervision (caseload review, data discussion) is unpaid time. And BTs and LaBAs must deliver 1:1 treatment in person — no remote service delivery. MCOs mirror this baseline (Texas Children's Health Plan's autism guideline repeats it nearly verbatim), but only TCHP was checked in depth — confirm each MCO's provider manual for staff-level extras at contracting. [2][6][7][8][9][10][11][12]

## Intake gates

The questions that decide whether a family can start with Texas Medicaid (THSteps-CCP), and what they have to bring.

- **Age limit**: Birth through 20 years of age on the date of service; clients become ineligible for CCP services the day of their 21st birthday. CHIP is excluded from the ABA benefit entirely. [2]
- **Diagnosis recency**: The ASD diagnosis must be made or reconfirmed within 3 years of initiation or recertification. Past 3 years the TMPPM requires a comprehensive re-evaluation of ASD symptom severity levels per DSM criteria before the PA can proceed. [2]
- **Who may diagnose**: A developmental pediatrician, neurologist, psychiatrist, licensed psychologist, or an interdisciplinary diagnostic team (a physician, PA or NP in consultation with qualified child specialists with autism expertise). The diagnosis must be documented with DSM criteria and a symptom severity level. [2]
- **Diagnostic tools required**: A reliable, valid, standardized diagnostic assessment tool or combination of tools — the TMPPM names the Autism Diagnostic Observation Schedule, the ADI-R and the Childhood Autism Rating Scale as examples. Screening tools alone (STAT, M-CHAT-R) cannot replace a validated diagnostic instrument. [2]
- **Referral required?**: Two signed referrals. For the evaluation: a signed, dated referral from the prescribing provider, signed within 60 calendar days prior to or on the anticipated evaluation date. For treatment: a signed, dated referral from a physician or allowed practitioner (MD/DO, PA, NP, or CNS with properly delegated authority) outlining the frequency and duration of treatment, with a signature current to the service dates — on or before the service start date and no older than three months. Since 4/1/2025 the prescriber signature is no longer required on the CCP PA form for the 90-day treatment extension; the initial 180-day treatment plan still needs it. [2][3]
- **Telehealth**: Synchronous audio-visual only, modifier 95, and only on 97151, 97155, 97156, 97158 and 99366. One-on-one services delivered directly to the child by a behavior technician or LaBA must be delivered in person — the TMPPM prohibits telehealth for BT/LaBA-delivered direct service. [2]
- **Prior-auth decision time**: Fee-for-service through TMHP: when a CCP request needs physician review, TMHP's Physician Reviewer "will complete the review within three business days of receipt of the completed prior authorization request," with "an additional three business days" when a peer-to-peer with the prescriber is needed. The clock runs from a COMPLETE request: an incomplete one is held while TMHP makes at least three contact attempts, and if the missing information "is not received within 14 business days of the request receipt date, the request will be denied as 'incomplete.'" The federal ceiling for state agencies since 1/1/2026 is 7 calendar days standard and 72 hours expedited (42 CFR 440.230(e)), unless state law sets a shorter one. The windows that actually cost money are the provider-side ones in § 2.3.11: the evaluation PA goes in within 60 days before or on the evaluation date; initial treatment within 3 business days of the start-of-care date (later requests are denied for dates before receipt); the 90-day extension is timely "within 30 days prior to the end of the current authorization period"; and a 180-day recertification must be received "no earlier than 60 days before the current authorization period expires" — anything filed after the end date is denied for the gap. Managed-care members follow their MCO's clock (Texas law: 3 business days, see the MCO guides). [2][14][15]
- **Other insurance (who pays first)**: Medicaid is the payer of last resort: a provider "must seek reimbursement from available third party insurance that the provider knows about or should know about before billing Texas Medicaid." Bill the commercial plan (or TRICARE, which the TMPPM lists as a third party resource) first, then file with TMHP within 95 days of the other insurer's payment or denial and within 365 days of the date of service, with the EOB's disposition date; if the other insurer has not answered after 110 days, TMHP will consider the claim. Get the Medicaid PA even when Medicaid is secondary — § 5.1.4: "If a client's primary coverage is private insurance and Medicaid is secondary but prior authorization is required for Medicaid reimbursement, providers must follow the guidelines and requirements listed in the handbook for that service." The one bill-Medicaid-first option in Section 8 ("THSteps medical and dental providers are not required to bill other insurance before billing Medicaid") names only THSteps medical and dental (checkup) providers; ABA is a CCP service, so bill the other coverage first. Exceptions to last-resort: in STAR Health (foster care) "Medicaid is primary … Providers must not bill other health insurance unless there is a court order," and CHAMPVA pays before Medicaid. The family owes nothing past the other insurer's payment for a Medicaid-covered service. [16][17][18][19]

## Delivery and billing rules

Coverage decides whether Texas Medicaid (THSteps-CCP) pays. These decide whether the claim survives: staffing and supervision, concurrent billing, per-day ceilings, who signs the note, where the service is payable, and whose NPI the claim goes out under.

- **Supervision**: The TMPPM sets no numeric ratio of its own: LBAs must directly supervise LaBAs and behavior technicians in accordance with Texas state licensure, which makes the certifying body's floor operative — for RBT-credentialed staff, the BACB minimum of supervision on at least 5% of service hours each calendar month with two face-to-face contacts. Only direct supervision, where the LBA directly observes the LaBA or BT providing services with the child, is reimbursable, under 97155; indirect supervision (caseload review, data discussion) is unpaid time. [2][7]
- **Concurrent billing (97153 + 97155)**: Prohibited: Texas Medicaid will not reimburse multiple ABA providers during one ABA session with the child when more than one ABA provider is present. The one exception is when the family and the child are receiving separate services and the child is not present in the family session. Providers may request total authorized hours under either 97153 or 97155 and bill the code matching the service actually delivered, but not both for the same clock time with the child present. [2]
- **Daily limits / MUEs**: Direct treatment is limited to 8 hours (32 units) per day, inclusive of 97153, 97154, 97155 and 97158. The 97151 evaluation and each re-evaluation are limited to 6 hours (24 units). Group treatment requires at least 2 and no more than 8 children. Authorization runs as two consecutive 90-day periods, then recertifications in increments of up to 180 days. [2]
- **Session-note signature**: Rendering ABA providers must sign each entry with full signature and credentials, and additional supervisory signatures must be made in accordance with state licensure requirements. Treatment notes for 97153/97154 carry the child's name, date of service, start and stop times, treatment goals addressed, progress and a summary of activities and interventions; 97155/97158 notes add protocol-modification decision points and progress assessments. The 97151 evaluation and the post-90-day progress summary each require a dated signature from the LBA and from the parent or caregiver. [2]
- **Place of service**: Home, clinic, office and community settings are payable, and ABA may be delivered across settings. Schools are permitted for coordination of care — school personnel of the same discipline participating to coordinate care are not treated as duplicates, and interdisciplinary team meetings bill under 99366 with an ABA PA on file — but services delivered by a behavior technician in the school setting as a shadow, an aide, or to provide general support are excluded. BT and LaBA direct treatment must be in person in any setting. [2]
- **Bill as provider**: Only the LBA enrolls in Texas Medicaid and bills. LaBAs and behavior technicians may not enroll; their services are billed under the supervising LBA's NPI with the credential modifier identifying the rendering staff level — HO for the LBA, HN for the LaBA, HM for the behavior technician. 97151 takes the HO modifier only; 97155, 97156 and 97158 take HO or HN; 97153 takes no required credential modifier. The 97155 supervision claim likewise goes out under the LBA's NPI. [2]

## What intake should collect for Texas Medicaid (THSteps-CCP)

- **Program & plan:** FFS vs. STAR / STAR Kids / STAR Health, and which MCO — same clinical rules, different PA machinery.
- **ASD diagnosis + date:** Diagnoser type matters (TMPPM list), and the dx must be made or reconfirmed within 3 years — screen recency at intake.
- **Prescriber referral:** A signed referral from the prescribing provider attaches to the evaluation PA — chase it first, not last.
- **Age check:** Benefit runs birth through 20 and ends on the 21st birthday; CHIP members are excluded entirely.
- **Supervising LBA:** Only LBAs enroll in Texas Medicaid — confirm the enrolled LBA who will bill for the team.

## Verification of benefits (VOB) data

How Texas Medicaid (THSteps-CCP) ABA benefits route and read on an eligibility check. Data last updated 2026-07-23.

### EDI routing

- **Payer ID (pVerify):** 00186

- **Real-time eligibility:** Yes
- **Behavioral health administrator:** none
- **ABA rides on:** medical benefit
- **Two-hop verification required:** No

A separate 2120C loop, present only for members with an assigned PCP or provider lock-in, carries the Primary Care Physician's name — NOT the MCO name.
- **Eligibility span granularity:** Date range, not a fixed monthly bucket — DTP*356 (coverage begin) and DTP*357 (coverage end) in D8 (CCYYMMDD) format on the 'Covered Managed Care' EB segment carry the actual enrollment span, which can run for any number of days/months per the companion guide's own example (20141001–20150430).

Managed-care codes returned in the 271:

| Code | Meaning |
| --- | --- |

### Contacts

- **Provider services phone:** 800-925-9126
- **Phone menu path:** Contact Center menu routes by topic — ask for "Authorizations" or "Eligibility"; a separate Third Party Resource (insurance verification) line runs 8 a.m.–5 p.m. CT. EDI/TexMedConnect technical issues route to the EDI Help Desk (1-888-863-3638), already cited in this guide's edi.verifyVia.
- **Hours:** 7 a.m.–7 p.m. Central Time, Monday–Friday
- **Portal:** [TMHP.com / TexMedConnect provider portal](https://www.tmhp.com/)

Questions to ask on a verification call:

- Do you have a distinct Availity or Change Healthcare payer ID for Texas Medicaid/TMHP 270/271 eligibility checks, separate from pVerify code 00186?
- Beyond the STAR/STAR Kids/CHIP program code carried in EB05, is there a fixed lookup table mapping REF02 codes to specific MCO names (e.g., Superior vs. Wellpoint), or does the MCO name only ever appear as free text?
- Is the Autism Services copay or coinsurance charged per visit or per day, and does the member's out-of-pocket maximum apply to this benefit?
- Are CPT codes 97152, 97157, 0362T, and 0373T billable under THSteps-CCP Autism Services at all, under a different program, or not covered?
- Is there a daily or weekly unit cap for 97156 (parent/caregiver training) or 99366 (interdisciplinary team meeting)?

## Common questions

### Does Texas Medicaid cover ABA therapy?

Yes — since February 1, 2022, as the Autism Services benefit under THSteps-CCP (EPSDT), for members from birth through age 20 with an ASD diagnosis. Everything requires prior authorization, from the evaluation forward. CHIP is excluded.

### How recent does the autism diagnosis need to be?

The diagnosis — with DSM criteria and a symptom severity level — must be made or reconfirmed within the 3 years before the PA request. Older diagnoses need reconfirmation before the evaluation PA can be approved.

### What changed on April 1, 2025?

TMHP removed the prescribing-provider signature requirement from the CCP PA form for the 90-day treatment extension. The initial 180-day treatment plan still needs the prescriber's signature; the mid-cycle extension no longer does.

### What does Texas Medicaid pay for ABA?

Effective September 1, 2025 (an ~11.5% increase): 97153 direct treatment pays $14.50 per 15-minute unit, 97151 evaluation $27.56, 97155 $20.08–$25.10 and 97156 $18.40–$23.01 depending on the LaBA/LBA modifier tier. Confirm current values in the TMHP Online Fee Lookup.
