Cook Children's Health Plan ABA coverage (Texas Medicaid MCO).

Last updated September 20267 primary sources

Cook Children's Health Plan — the pediatric-focused plan affiliated with Cook Children's Health Care System, serving STAR and STAR Kids across six North Texas counties (Wise, Denton, Parker, Tarrant, Hood, and Johnson) — publishes an unusually deep ABA provider-education footprint for a Texas MCO: a dedicated 123-page "Applied Behavior Analysis" training deck plus a separate acute-PA training covering ABA mechanics in detail. Read closely, it's a faithful restatement of TMPPM §2.3 rather than a distinct plan overlay — the value here is the clarity and depth of the restatement, not a different rulebook. We found no ABA process that differs between STAR and STAR Kids in the plan's own materials.

This plan administers the Texas Medicaid (THSteps-CCP) ABA benefit — the state rules are the floor, and this page covers what the plan layers on top. Read it together with the Texas Medicaid (THSteps-CCP) guide →

The code and modifier table, restated in detail

Cook Children's own training confirms the statewide code set with granular billing notes: 97151 (evaluation/re-evaluation) caps at 6 hours/24 units with a 30-day authorization window and takes the HO modifier only; 97153 and 97154 (direct and group treatment) take no required modifier (HO/HN/HM are informational); 97155, 97156, and 97158 require an HO or HN modifier; and 99366 (interdisciplinary team meetings) takes no modifier, is reimbursable only against an F84.0 autism diagnosis, is capped at twice per year, and requires at least three licensed professionals — one of them the LBA — meeting for a minimum of 30 minutes. Direct treatment caps at 8 hours/day combined across 97153, 97154, 97155, and 97158. Telehealth (modifier 95) is allowed for 97151, 97155, 97156, 97158, and 99366; the plan's materials specifically note LaBAs and RBTs may not deliver any service remotely.[1][2]

Submitting through EpicCare Link

Cook Children's runs authorization through an EpicCare Link secure provider portal, and its determination letters are delivered only through the portal's In Basket — the plan states explicitly that PA determination letters will not be faxed. Fax submission (STAR/CHIP: 682-885-8402; STAR Kids: 682-303-0005 or 844-843-0005) is offered only for providers whose portal access is still pending. The plan uses the statewide-style CCP Prior Authorization Request Form with a dedicated ABA checkbox and section. One inconsistency to route around: the plan's own materials print at least three different variants of its PA-inquiry email address across different documents — call Provider Support Services at 1-888-243-3312 to confirm the current address rather than guessing from a specific PDF.[3][4]

Intake gates

The questions that decide whether a family can start with Cook Children's Health Plan, and what they have to bring. Each maps onto something intake should ask on the first call.

Age limit

Follows the Texas Medicaid (TMPPM) rule: birth through 20 years of age on the date of service, with eligibility ending the day of the 21st birthday. CHIP members are excluded from the ABA benefit.[5][1]

Diagnosis recency

Follows the Texas Medicaid (TMPPM) rule: the ASD diagnosis must be made or reconfirmed within 3 years of initiation or recertification; past 3 years a comprehensive re-evaluation of ASD symptom severity levels per DSM criteria is required first.[5][1]

Who may diagnose

Follows the Texas Medicaid (TMPPM) rule: 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).[5][1]

Diagnostic tools required

Follows the Texas Medicaid (TMPPM) rule: a reliable, valid, standardized diagnostic assessment tool or combination of tools — the manual names the ADOS, ADI-R and CARS as examples. Screening instruments alone (STAT, M-CHAT-R) do not substitute.[5][1]

Referral required?

Follows the Texas Medicaid (TMPPM) rule: a signed, dated prescriber referral for the evaluation, signed within 60 calendar days before or on the anticipated evaluation date; and for treatment a signed, dated referral from a physician or allowed practitioner (MD/DO, PA, NP, or CNS with delegated authority) stating frequency and duration, signed on or before the service start date and no more than 3 months old. Since 4/1/2025 the prescriber signature is no longer required on the CCP PA form for the 90-day extension.[5][1][7]

Telehealth

Cook Children's own ABA training restates the state rule: telehealth (modifier 95) is allowed for 97151, 97155, 97156, 97158 and 99366, and its materials specifically note that LaBAs and RBTs may not deliver any service remotely.[1][5]

Prior-auth decision time

Cook Children's own table: "Routine — Within 3 business days after receiving the request / Urgent — Within 1 business day after receiving the request / Inpatient (Concurrent) — Within 1 business day … / Emergent/Life Threatening — Within 1 hour after receiving the request"; a request with no priority marked defaults to routine, and "Requests submitted that are not urgent in nature, but rather submitted as urgent based on the delay in Provider submission will be processed as routine." Incomplete requests are returned listing the missing elements; the plan "must receive the requested information within three business days from the date of the letter," after which it decides "based solely on the information that we have." Cook's ABA training restates the TMPPM windows: evaluation PA "within 60 days prior to or on the requested evaluation date"; initial treatment "within 3 business days of the start of care (SOC) date"; the 90-day request 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." Late requests are denied for dates before receipt.[8][2][1]

Other insurance (who pays first)

"Medicaid is secondary when coordinating benefits with all other insurance coverage, unless an exception applies under federal law … Providers must submit claims to other health insurers for consideration prior to billing Cook Children's Health Plan"; if the plan knows of other coverage the provider did not bill, the claim denies. The secondary claim "Must be received by the health plan within ninety-five days of the disposition date on the primary insurance Explanation of Benefits (EOB)." Cook's materials do not say whether its ABA PA is still needed when it pays second — request it.[8][1][9]

Delivery & billing rules

Coverage decides whether Cook Children's Health Plan pays. These decide whether the claim survives: how sessions must be staffed and supervised, what may be billed concurrently, the per-day ceilings, who signs the note, where the service is payable, and whose NPI the claim goes out under.

Supervision

Follows the Texas Medicaid (TMPPM) rule: the manual sets no numeric ratio of its own, requiring LBAs to directly supervise LaBAs and behavior technicians in accordance with Texas licensure and deferring to the certifying body's minimums — for RBT-credentialed staff the BACB floor of supervision on at least 5% of service hours each month with two face-to-face contacts. Only direct supervision, where the LBA observes the LaBA or BT with the child, is reimbursable (under 97155); indirect supervision is unpaid.[5][1][6]

Concurrent billing (97153 + 97155)

Follows the Texas Medicaid (TMPPM) rule: concurrent billing is prohibited — Texas Medicaid will not reimburse multiple ABA providers during one session with the child when more than one provider is present. The single exception is when the family and the child receive separate services and the child is not present in the family session. Total authorized hours may be requested under either 97153 or 97155 and billed as the code matching the service actually delivered — not both for the same clock time with the child present.[5][1]

Daily limits / MUEs

Cook Children's training restates the state caps and adds code-level detail: direct treatment is capped at 8 hours/day combined across 97153, 97154, 97155 and 97158; 97151 caps at 6 hours / 24 units with a 30-day authorization window; and 99366 is reimbursable only against an F84.0 diagnosis, twice per year, requiring at least three licensed professionals (one the LBA) meeting for a minimum of 30 minutes.[1][5]

Session-note signature

Follows the Texas Medicaid (TMPPM) rule: rendering ABA providers must sign each entry with full signature and credentials, with additional supervisory signatures per state licensure. Treatment notes carry the child's name, date of service, start and stop times, goals addressed, progress and a summary of interventions; 97155/97158 notes add protocol-modification decision points. The 97151 evaluation and the 90-day progress summary each need a dated signature from the LBA and from the parent or caregiver.[5][1]

Place of service

Follows the Texas Medicaid (TMPPM) rule: home, clinic, office and community settings are payable. In schools, services delivered by a behavior technician as a shadow, an aide, or as general support are excluded; school personnel participating to coordinate care are not counted as duplicate providers, and interdisciplinary team meetings bill under 99366 against an ABA PA. BT and LaBA direct treatment must be in person in every setting.[5][1]

Bill as provider

Follows the Texas Medicaid (TMPPM) rule: only the LBA enrolls in Texas Medicaid and bills. LaBAs and behavior technicians may not enroll — their services go out under the supervising LBA's NPI with the credential modifier identifying who rendered (HO = LBA, HN = LaBA, HM = behavior technician; 97151 takes HO only, 97155/97156/97158 take HO or HN). The LBA must directly employ or contract with every LaBA and BT on the team. Cook Children's training spells the modifier rules out: 97151 takes the HO modifier only; 97155, 97156 and 97158 require HO or HN; 97153 and 97154 take no required modifier (HO/HN/HM are informational); 99366 takes no modifier.[1][5]

Does STAR Kids have different ABA rules than STAR at Cook Children's?

We found no distinguishing STAR Kids ABA process in the plan's own materials — the ABA policy applies uniformly across Medicaid, CHIP, and STAR Kids.

How do I submit an ABA PA to Cook Children's?

Through the EpicCare Link secure provider portal, using the Comprehensive Care Program PA form. Fax (682-885-8402 for STAR/CHIP) is available only while portal access is pending — determination letters are delivered via the portal only, not by fax.
