UnitedHealthcare of New England holds one of the three EOHHS Medicaid managed care contracts (Amendment 21, effective July 1, 2026), and that contract requires it to provide HBTS, including ABA, to Medicaid members under 21. Its behavioral health benefit runs through United Behavioral Health operating as Optum: the 2026 Rhode Island Care Provider Manual says outpatient behavioral health is "Covered through Optum."
What the manual does not do is describe ABA or HBTS at all, so the state rules in the EOHHS certification standards and the managed care contract are the published floor. Treat the plan’s prior authorization tool as the source for each code.
The EOHHS contract says HBTS "is an intensive home or community-based service" that includes "Applied Behavioral Analysis discrete trial interventions," that "The Contractor must provide these services to any Medicaid member under age 21," and that each plan designs its level-of-care criteria and payment method for EOHHS approval while contracting with a named list of HBTS and ABA agencies. UnitedHealthcare’s 2026 manual covers behavioral health generally ("Members may access all behavioral health outpatient services... Prior authorization may be required for more intensive services, day treatment or partial, inpatient, or residential care") and points to the national Optum network manual, which "generally applies to all types of business." No ABA-specific rule appears.[2][1]
Optum’s Rhode Island page says Medicaid managed care network providers "are required to be screened by and enrolled with the State of RI Medicaid program," otherwise "all claims/encounters may be denied"; once Gainwell approves, email Optum to add the Medicaid network to your profile. The manual says UnitedHealthcare Community Plan "is the payer of last resort" and wants the primary payer’s EOB with the claim, and that a rejected claim not corrected "within 365 days from date of service or per care provider contract" is denied as late; "If you don’t know your timely filing limit, refer to your Provider Agreement." Member appeals go in "within 60 calendar days from the date of the adverse benefit determination," and standard appeals are resolved in 30 calendar days.[3][1]
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."[8][9][7]
The questions that decide whether a family can start with UnitedHealthcare Community Plan of Rhode Island, and what they have to bring. Each maps onto something intake should ask on the first call.
Under 21. The plan’s EOHHS contract requires HBTS for "any Medicaid member under age 21, per Federal EPSDT regulation."[2]
The plan publishes nothing of its own; the state rule is a diagnosis "made within 3 years."[1][5]
The plan names no list; the state rule is a "qualified licensed health care professional," with an evaluation by a licensed mental health professional within three years.[1][5]
The plan publishes nothing different from the state, where HBTS is "based upon medical necessity, as documented by a physician’s prescription," and the licensing law has a licensed analyst provide ABA only when prescribed by a child psychiatrist, behavioral developmental pediatrician, child neurologist or child-trained psychologist.[1][5][13]
The manual’s medical-management table gives non-urgent pre-service decisions "Within 5 working days of receipt of medical record information or no longer than 7 calendar days of receipt," urgent within 72 hours, concurrent within 3 calendar days. Federal law caps standard Medicaid managed care decisions at 7 calendar days for rating periods from January 1, 2026.[1][10]
"UnitedHealthcare Community Plan is the payer of last resort. Other coverage should be billed as the primary carrier. When billing UnitedHealthcare Community Plan, submit the primary payer’s EOBs or remittance advice with the claim."[1][11]
Optum’s Rhode Island telehealth alert (BH5027, August 2023) says for UHC Medicaid: "Use standard outpatient CPT/HCPCS codes listed on your fee schedule," "No telehealth modifier needed," and "POS 10 for in the home POS 02 for outside of the home." The alert predates the 2026 contracts and names no ABA codes. Under its EOHHS contract the plan may not exclude a service only because it is delivered by telemedicine, pay behavioral health providers less, or impose stricter prior authorization.[4][2]
Ask the plan: Optum Provider Services Rhode Island, 1-877-614-0484: confirm the alert still applies and which HBTS components may be delivered by telehealth.
Coverage decides whether UnitedHealthcare Community Plan of Rhode Island 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.
UnitedHealthcare Community Plan publishes no ABA supervision ratio of its own; the state standard applies. The EOHHS managed care contract requires HBTS direct services to be delivered "under the supervision of a licensed healthcare professional"; the clinical supervisor must be a Rhode Island licensed health care provider with a master’s or doctoral degree, must "Observe worker in the home with the child implementing the Treatment Plan on a monthly basis," and ABA "can be overseen by a Board-Certified Behavior Analyst (BCBA) or a licensed trained professional (e.g., Psychologist)." The 2016 EOHHS certification standards changed clinical supervision "from 2 hours per week to 8 hours total per month." Direct-care workers must be at least 19, with a high school diploma and experience or coursework.[1][2][5]
The plan publishes no ABA session-note rule of its own. The state HBTS standard applies: record entries "dated and authenticated," changes "signed by the service provider," and treatment plans signed by a Licensed Practitioner of the Healing Arts and by the parents.[1][5]
The plan publishes no setting rule; the contract describes HBTS as home or community-based and "not intended to replace or substitute for educational services."[1][2]
Not addressed in the manual, and EOHHS publishes no rule either.[1]
Ask the plan: Optum/UnitedHealthcare behavioral health provider line, 1-855-766-0344, or your provider agreement.
The manual publishes no HBTS or ABA unit limit.[1]
Ask the plan: UnitedHealthcare Community Plan behavioral health, 1-855-766-0344: ask how HBTS units are authorized.
The manual requires an NPI to see Medicaid members, clean claims with "your NPI and federal TIN," and every Medicaid network provider enrolled with Rhode Island Medicaid. It does not say whether HBTS lines carry the agency’s or the clinician’s NPI as rendering.[1][3]
Ask the plan: Optum Provider Services Rhode Island, 1-877-614-0484: ask which NPI goes in the rendering field for T1024 and H0046.
Yes, for Medicaid members under 21, as part of Home Based Therapeutic Services required by its EOHHS contract. Behavioral health runs through Optum.
The 2026 manual does not say for ABA. Check each HBTS code in the UnitedHealthcare Provider Portal prior authorization tool or call 1-855-766-0344.
Yes. Optum says Medicaid managed care network providers must be screened and enrolled with Rhode Island Medicaid, or claims may be denied.
