Rhode Island Medicaid does not run ABA as a stand-alone program. It is a subset of Home Based Therapeutic Services (HBTS), the EOHHS-certified home and community service for Medicaid children with chronic, moderate to severe developmental, cognitive, medical or psychiatric conditions. The 2016 EOHHS certification standards, still the ones EOHHS posts, describe ABA as "Subset of HBTS," delivered by provider agencies EOHHS has approved to run an ABA program, with extra lead therapy and clinical supervision hours that "can only be provided for ABA recognized providers."
Two facts shape every Rhode Island Medicaid ABA referral. The child’s health plan pays: the 2026 managed care contracts require Neighborhood Health Plan of Rhode Island, UnitedHealthcare Community Plan and Tufts Health Public Plans to provide HBTS and ABA "to any Medicaid member under age 21, per Federal EPSDT regulation." And billing runs on HCPCS codes (T1024, H0046, H2014, T1016), not on the CPT 97151–97158 codes commercial payers use, with fee-for-service rates set through OHIC’s rate review.
EPSDT "applies to all children and youth under 21 years old who are enrolled in Medicaid," and EOHHS says the benefit "does not allow for ‘hard limits’ on services," with prior authorization "required for all EPSDT services that are not in the normal scope of covered services." HBTS is how Rhode Island delivers intensive home and community behavioral treatment under that benefit. Its eligibility runs from birth to the 21st birthday for children eligible through SSI, Katie Beckett (through age 18), adoption subsidy, RIte Care or RIte Share, with a chronic (12 months or more) moderate to severe condition that significantly compromises functioning. ABA discrete trial intervention is one form of HBTS specialized treatment, offered "through approved ABA provider-agencies."[4][2][6][7][8][9]
EOHHS posts three Medicaid managed care contracts, each at Amendment 21 effective July 1, 2026: Tufts Health Public Plans, UnitedHealthcare of New England, and Neighborhood Health Plan of Rhode Island. All three contain the same children’s services attachment. It says HBTS, PASS and respite "have historically been accessible outside of the MCO’s scope of benefits through Medicaid Fee- For- Services," that EOHHS now integrates them, and that "The Contractor must provide these services to any Medicaid member under age 21." Each plan designs its own level-of-care criteria and payment method, both subject to EOHHS approval, and must contract with a named list of HBTS and ABA agencies. So the first intake question is which plan is on the card.[4][2][6][7][8][9]
An agency becomes an HBTS provider by EOHHS certification. EOHHS accepts applications on an ongoing basis, reviews them in writing (allow "a minimum of two months"), and approves for an initial three years; an agency that wants to deliver ABA answers the separate Appendix 6 questions on curriculum, skills assessment, teaching procedures, functional assessment and staff training, and center-based ABA needs Appendix 7 approval. For fee-for-service members, "Prior authorization from each HBTS provider using a batch form shall be sent once a week, prior to the start date of service, to EOHHS." EOHHS’s general prior authorization page says the state responds to standard requests "within 7 days" and expedited ones within 72 hours. Treatment hours must be justified by medical necessity "up to 20 hours" a week for HBTS, and up to 25 when HBTS and PASS are combined.[2][14][10][11][12][13][27][28]
Rhode Island Medicaid does not pay ABA on the CPT codes 97151–97158. OHIC’s 2025 rate review says HBTS and ABA "currently use the same procedure codes," and both Neighborhood’s Medicaid payment policy and Tufts Health RITogether’s ABA guideline list only HCPCS codes. The fee-for-service rates OHIC reported as current in August 2025 are: T1024 home-based specialized treatment and treatment support $33.30 per 15 minutes; H0046 lead therapy $38.67 per 30 minutes; H0046-HO clinical supervision by a master’s-level clinician $59.07 and H0046-HP by a doctoral-level clinician $69.81, both per 30 minutes; H2014 specialized treatment consultation and H2014-HO $29.54, H2014-HP $34.91, per 15 minutes; T1016 treatment coordination $21.98 and T1013 interpretation $27.48 per 15 minutes. OHIC recommended its independent rate model figures instead (T1024 $36.14, H0046 $35.98, H0046-HO $61.49, H0046-HP $65.96, H2014 $39.44, H2014-HO $37.23, H2014-HP $39.85, T1016 $21.67, T1013 $28.34). The FY2027 budget adopts OHIC’s recommendations effective October 1, 2026, except where a rate would exceed Medicare. EOHHS says the October 1, 2026 fee schedule "is not yet posted" and the increases need federal approval, so rates will be applied retroactively once it is. EOHHS also uses these FFS rates as a minimum fee schedule the health plans must pay.[2][14][10][11][12][13][27][28]
Rhode Island licenses behavior analysts (R.I. Gen. Laws ch. 5-86). The HBTS standards require clinical supervisors and treatment consultants to hold a Rhode Island license (a BCBA is on both lists), and add that "EOHHS will only allow the provision of Clinical Supervision and Treatment Consultation by individuals in possession of a BCBA" among behavior analysts. For a clinician licensed in another state, the standards ask the agency to show an active license from the issuing state, a pending Rhode Island application, and then confirm the Rhode Island license.[2][20][21][22][16]
Rhode Island licenses behavior analysts, so a BCBA licensed elsewhere cannot simply treat a Rhode Island child. Under R.I. Gen. Laws § 5-86-21(g), an analyst "licensed or certified in another state" may practice in Rhode Island without a Rhode Island license "for up to ten (10) calendar days per calendar year with no more than five (5) days of this activity occurring consecutively." Beyond that, the clinician needs a Rhode Island license (LBA) from the Department of Health board, which requires passing the BCBA exam and keeping active BACB status (§ 5-86-9). Chapter 5-86 has no telehealth exception and no reciprocity section. For Medicaid telehealth, EOHHS is explicit: an out-of-state provider may serve Medicaid members by telehealth only with "an active and unrestricted license in the state of Rhode Island" and Rhode Island Medicaid enrollment; "Out-of-state licensure alone does not confer eligibility."[2][20][21][22][16]
Fee-for-service claims go to Gainwell Technologies and must be received "within 365 days of the date of service"; claims with another insurer must be filed within 90 days of that payer’s EOB when the service is over a year old. Claims are processed about every two weeks and paid by direct deposit only. A provider can appeal a denied fee-for-service prior authorization with EOHHS’s Provider Appeal Form, but to appeal for the member the provider must be designated the member’s authorized representative. EVV does not reach ABA: EOHHS says "Electronic visit verification (EVV) is required for Personal Care and Home Health Care Agency services provided in the home," and its EVV service and procedure code list contains personal care, homemaker and home health aide codes, not HBTS codes. In managed care, the contracts define timely payment as "within thirty (30) days of receipt of a ‘clean claim’"; each plan sets its own filing limit and appeal window (see the plan guides).[15][14][18][19][17][7]
Telehealth is a covered mode for any medically necessary Medicaid service. The 2026 managed care contracts apply the Telemedicine Coverage Act (R.I. Gen. Laws ch. 27-81): a plan may not exclude a service "solely because it is provided through Telemedicine," may not pay behavioral health providers less than in person, may not impose stricter prior authorization, and may not restrict originating sites; the home counts "where Medically Necessary and Clinically Appropriate." EOHHS’s Telemedicine Billing Guidance (effective September 1, 2025) adds that the patient must be present in real time, the service must meet the in-person standard of care, audio-only needs a documented reason and verbal consent, and providers "must have availability for both telehealth and in-person services." Home health and home care agencies are on its list of excluded provider types; HBTS and ABA agencies are not. No EOHHS document read lists telehealth rules for the HBTS codes specifically (which components may be remote, or a modifier).[7][23][29][16]
The questions that decide whether a family can start with Rhode Island Medicaid, and what they have to bring. Each maps onto something intake should ask on the first call.
Under 21: HBTS covers "Children birth to their 21st birthday who are Medicaid eligible," and EPSDT applies to all Medicaid members under 21. Katie Beckett eligibility runs through age 18.[2][4]
Within 3 years. Treatment plan approval needs a formal diagnosis "made within 3 years by a qualified licensed health care professional," and "A previous evaluation by a licensed mental health professional must have taken place within three years prior." EOHHS’s 2017 ABA fact sheet said "within the last two years"; Neighborhood’s 2026 policy says three.[2][5][27]
A "qualified licensed health care professional" (diagnosis) and a "licensed mental health professional" (the evaluation within 3 years). The state names no narrower list for Medicaid; separately, the licensing law has a licensed analyst provide ABA only when prescribed by a child psychiatrist, behavioral developmental pediatrician, child neurologist or child-trained licensed psychologist.[2][31]
The state requires "at a minimum, a clinical diagnostic interview," with neuropsychological, psychological, educational testing or a language evaluation "as necessary." It names no specific instrument; the health plans do (see their guides).[2]
Yes: HBTS is "based upon medical necessity, as documented by a physician’s prescription," and "Prescriptions for service shall be obtained by the provider-agency." The treatment plan itself must be signed by a Licensed Practitioner of the Healing Arts. R.I. Gen. Laws § 5-86-2(8) separately has a licensed analyst provide ABA only when prescribed by a child psychiatrist, behavioral developmental pediatrician, child neurologist or child-trained licensed psychologist.[2][31]
Telehealth is a covered mode for any medically necessary Medicaid service. The 2026 managed care contracts apply the Telemedicine Coverage Act (R.I. Gen. Laws ch. 27-81): a plan may not exclude a service "solely because it is provided through Telemedicine," may not pay behavioral health providers less than in person, may not impose stricter prior authorization, and may not restrict originating sites; the home counts "where Medically Necessary and Clinically Appropriate." EOHHS’s Telemedicine Billing Guidance (effective September 1, 2025) adds that the patient must be present in real time, the service must meet the in-person standard of care, audio-only needs a documented reason and verbal consent, and providers "must have availability for both telehealth and in-person services." Home health and home care agencies are on its list of excluded provider types; HBTS and ABA agencies are not. No EOHHS document read lists telehealth rules for the HBTS codes specifically (which components may be remote, or a modifier).[7][23][29][16]
Fee-for-service: EOHHS "will respond to standard prior authorization requests within 7 days of their submission. Expedited or urgent requests will be responded to within 72 hours," matching the federal floor in effect since January 1, 2026 (42 CFR 440.230(e)). A request can come back deferred for more information. Managed care: the 2026 contracts still print 14 calendar days for standard decisions, but for rating periods starting on or after January 1, 2026 federal law caps it at 7 (42 CFR 438.210(d)) (the 2026 Rhode Island contract amendments are effective July 1, 2026).[14][24][7][32]
Medicaid pays last. For ABA, "EOHHS requires proof of commercial insurance coverage," and "Medicaid will assume responsibility for payment of the ABA treatment once the commercial health care coverage benefit has been exhausted. Payment will revert back to the commercial insurance at the start of every benefit year." Deductibles and copayments may be covered by Medicaid up to its allowable amounts. The contracts make "Rhode Island Medicaid … the payor of last resort for all Covered Services." Because the commercial mandate runs only until age 15, check whether the commercial plan still covers ABA for an older child before billing Medicaid as secondary.[2][7][25][33]
Coverage decides whether Rhode Island Medicaid 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.
Clinical supervision is "a required component of HBTS for both Specialized Treatment and Treatment Support," provided only by Rhode Island licensed clinicians (LICSW, LCSW, MFT, mental health counselor, psychologist, or BCBA). The 2016 standards changed supervision "from 2 hours per week to 8 hours total per month." The managed care contracts add that the supervisor must "Observe worker in the home with the child implementing the Treatment Plan on a monthly basis" and provide group supervision when two or more workers treat a child. ABA "can be overseen by a Board Certified Behavior Analyst (BCBA) or a licensed trained professional (e.g., Psychologist)"; the lead therapist reports to the behavior analyst or clinical supervisor.[2][7]
No current per-day ceiling was found in a document we could open (the fee schedule is behind a license form). The 2021 HBTS/ABA addendum’s grid lists maximum units per day (T1024 20 units of 30 minutes; T1016 16 of 15 minutes; H0046, H0046-HO and H0046-HP 12 of 30 minutes; S9446 6), but T1024 has since moved to a 15-minute unit. Weekly: HBTS hours must be justified "up to 20 hours" a week, up to 25 with PASS; Neighborhood applies the 20 hours "excluding ABA programs." EPSDT allows no hard limits.[3][2][10][30][4]
The treatment plan "is regarded as a prescription for services and must be signed by" a Licensed Practitioner of the Healing Arts, and "Parents/Caregivers/Guardians must sign all proposed Treatment Plans." Record entries must be "dated and authenticated," changes in the client’s condition are "recorded in the client record at the time of service provision and signed by the service provider," and "The client record will be the basis for billing all service hours." Plans are reviewed at least every six months.[2][7]
HBTS is delivered "in a child’s home, community, or outpatient setting"; center-based ABA is "reserved for EOHHS approved providers." HBTS "is not intended to replace or substitute for educational services," and Neighborhood excludes "Services provided in a school setting as part of the individual education plan (IEP)."[2][27]
Not addressed in any EOHHS source read. The HBTS codes separate direct service (T1024) from clinical supervision (H0046-HO/HP) and lead therapy (H0046), but no document says whether they may be billed for the same clock time. Two agencies may serve one child: the 2021 addendum has the secondary agency bill with an XP modifier.[2][3]
Blocked on: EOHHS Medicaid Customer Service Help Desk, (401) 784-8100, or the EOHHS children’s services administrator named on the HBTS/ABA addendum; ask whether H0046-HO and T1024 may overlap.
HBTS is billed by the EOHHS-certified provider agency on HCPCS codes; when two agencies serve one child, "The primary agency will bill for services as usual" and the secondary adds modifier XP. Clinician level is shown by modifier (HO master’s, HP doctoral). No EOHHS source read says whose individual NPI goes in the rendering field on fee-for-service claims.[3][2]
Blocked on: Gainwell Technologies provider representative or the Medicaid Customer Service Help Desk, (401) 784-8100: ask which NPI goes in the rendering field for T1024 and H0046.
Yes, for members under 21, as a subset of Home Based Therapeutic Services (HBTS). Most children get it through their health plan: Neighborhood Health Plan of RI, UnitedHealthcare Community Plan or Tufts Health RITogether.
No. Rhode Island Medicaid bills ABA on the HBTS HCPCS codes (T1024 direct service, H0046 lead therapy and clinical supervision, H2014 consultation, T1016 coordination). OHIC notes that HBTS and ABA "currently use the same procedure codes."
Per OHIC’s 2025 report, current FFS rates are T1024 $33.30 per 15 minutes, H0046 lead therapy $38.67 per 30 minutes, and clinical supervision $59.07 (master’s) or $69.81 (doctoral) per 30 minutes. OHIC-recommended increases (T1024 to $36.14) are budgeted from October 1, 2026, pending federal approval; the plans must pay at least the FFS rates.
Only briefly without a Rhode Island license: 10 calendar days a year, no more than 5 in a row (R.I. Gen. Laws § 5-86-21(g)). For Medicaid telehealth EOHHS requires an active Rhode Island license and Rhode Island Medicaid enrollment; out-of-state licensure alone does not qualify.
No. EOHHS applies EVV to personal care, homemaker and home health agency services, and its EVV code list has no HBTS codes.
Fee-for-service claims must reach Gainwell within 365 days of the date of service. Each health plan sets its own limit: 180 days for Neighborhood, 90 days for Tufts Health RITogether.
