Ohio's autism mandate is usually described backwards. R.C. 3923.84 does not cap ABA at 20 hours a week — it requires at least that much for an insured under age fourteen, and the same section says explicitly that it "shall not be construed as limiting benefits that are otherwise available to an insured under a policy." Ohio sets floors, not ceilings, and a clinic quoting "Ohio's 20-hour cap" to a family is giving away hours it is entitled to ask for.
The harder Ohio fact is who the mandate does not reach. The statute carves out non-grandfathered individual and small group plans entirely, alongside Medicare supplement, accident-only, specified-disease, hospital indemnity, disability income, long-term care and other limited-benefit policies. For a family on a marketplace or small-employer plan the ABA benefit rides on the ACA essential-health-benefits benchmark rather than on 3923.84 — and self-funded ERISA plans sit outside state insurance law altogether, answering to federal parity. Which bucket the plan falls in is the first thing benefits verification has to settle.
R.C. 3923.84 requires each individual and group sickness and accident policy delivered, issued for delivery or renewed in Ohio to cover the screening, diagnosis and treatment of autism spectrum disorder. R.C. 1751.84 is its twin for health insuring corporations, with identical substance. What the statute then sets out are minimums for an insured under the age of fourteen: twenty visits per year each for speech and language therapy and occupational therapy performed by a licensed therapist; twenty hours per week of clinical therapeutic intervention provided by or under the supervision of an appropriately licensed, certified or registered professional under a health treatment plan; and thirty outpatient mental or behavioral health visits per year for consultation, assessment, treatment-plan development or oversight by a licensed psychologist, a licensed physician including a psychiatrist, or a clinical nurse specialist or certified nurse practitioner.[1][2]
Two clauses stop those numbers becoming ceilings. Subsection (C)(1) says the section "shall not be construed as limiting benefits that are otherwise available to an insured under a policy." Subsection (A) says coverage is not subject to dollar limits, deductibles or coinsurance less favourable to the insured than those applying to substantially all medical and surgical benefits under the policy. So the 20 hours is the statutory floor for the under-14 cohort, and the actual authorization is a medical-necessity conversation that can and often should go higher.[1][2]
The exclusion sentence is the one to read out loud at intake: nothing in the section applies "to nongrandfathered plans in the individual and small group markets or to medicare supplement, accident-only, specified disease, hospital indemnity, disability income, long-term care, or other limited benefit hospital insurance policies." That is a large slice of the Ohio market. Those plans may still cover ABA — through the ACA essential-health-benefits benchmark or plan design — but not because 3923.84 says so, and the mandate arguments on this page will not move them.[1][2]
Unusually, Ohio writes prior authorization into the mandate rather than leaving it to the carrier. Subsection (C)(2) says a policy "shall stipulate that coverage provided under this section be contingent upon both of the following: (a) The covered individual receiving prior authorization for the services in question; (b) The services in question being prescribed or ordered by a psychologist trained in autism, a developmental pediatrician, or a clinical nurse specialist or certified nurse practitioner specializing in pediatric health." The nurse-practitioner and clinical-nurse-specialist pathway is new — Senate Bill 196 added it effective March 20, 2025, which widens the pool of clinicians who can legitimately order ABA in Ohio.[1]
The counterweight is subsection (D): outside inpatient services, an insurer "may review the treatment plan annually, unless the insurer and the insured's treating physician, clinical nurse specialist, certified nurse practitioner, or psychologist agree that a more frequent review is necessary," and the insurer covers the cost of obtaining any review or treatment plan. Annual is a generous statutory ceiling by the standards of this directory — Virginia's is 12 months, Missouri's is six. On a fully insured Ohio plan, an Anthem reviewer asking for an off-cycle treatment-plan update is asking for something the statute does not entitle them to without your agreement.[1]
Anthem's Ohio commercial entity is Community Insurance Company, and Ohio shares one precertification list with Indiana, Kentucky, Missouri and Wisconsin. Under behavioral health services that list includes, for OH, IN and KY Blues products, applied behavioral analysis among the services requiring preapproval — with the responsible party given as Anthem. A separate row reads "Treatment for autism spectrum disorder — Anthem." Since September 1, 2025 the preferred channel has been Availity Essentials: log in, select Authorizations and Referrals, then the Patient Registration tab.[6][10][7]
Two Carelon names cause confusion in Ohio and neither should send an ABA request anywhere new. Carelon Medical Benefits Management handles imaging, bariatrics, cardiovascular, genetic testing, musculoskeletal, oncology, sleep, radiation therapy and rehabilitative services — its published numbers are for those programmes, not ABA. And Anthem's March 2025 notice about delegating work to Carelon Health, Inc. is explicitly about care management, meaning case management and disease management: the notice itself says all contracts, policies and procedures remain unchanged, and that existing phone numbers, emails, websites and portals will not change. It says nothing about prior authorization, utilization management or ABA. Carelon Behavioral Health is separately a utilization-management vendor acting on the health plan's behalf in Ohio and took assignment of Ohio behavioral health provider contracts in 2023 — but from the clinic's side, the January 2026 precertification list names Anthem and the submission channel is Anthem's Availity.[6][10][7]
One nuance that can save a whole workup: on Anthem National Accounts business, "precertification for ABA is recommended and applies unless the group specifically opts out of clinical review for this benefit. Retrospective review is allowed." Customized precertification approaches for individual employer groups are described as common in National Accounts. If the card says National Accounts, make the call before you build the file.[6][10][7]
Ohio does not license "behavior analysts" — it certifies Certified Ohio Behavior Analysts through the State Board of Psychology. Applicants must demonstrate current BACB certification as a board certified behavior analyst, or completion of equivalent requirements plus a psychometrically valid examination from a nationally accredited credentialing organization. R.C. 4783.02 makes it unlawful to engage in the practice of applied behavior analysis in Ohio without that certificate, or to hold yourself out as a COBA without it.[3][4][5]
The exemptions define the technician tier. The chapter does not apply to "an individual practicing applied behavior analysis who is supervised by a certified Ohio behavior analyst and acting under the authority and direction of that certified Ohio behavior analyst," nor to "the delivery of interventions by a direct care provider or family member to implement components of an applied behavior analysis treatment plan." Ohio, in other words, does not separately license RBT-level staff; they work under the COBA's authority. Chapter 4732 psychologists and Chapter 4757 counselors, social workers and marriage and family therapists are also exempt within their training.[3][4][5]
The mismatch to watch: Anthem's multi-state ABA provider resource guide lists approved service providers broadly — psychiatrists, psychologists, LCSWs, LPCs, LMFTs with ABA training, BCBAs, people working under BCBA direction, and other state-licensed mental health providers. Ohio's insurance statute is narrower, requiring ABA to be provided by or under the supervision of a certified Ohio behavior analyst, a Chapter 4732 psychologist, or a Chapter 4757 counselor, social worker or marriage and family therapist. In Ohio a BCBA needs the COBA; credential to the statute.[3][4][5]
Effective January 1, 2026, Anthem reimburses ABA in Ohio on weekly approved units rather than total authorized units. Claims should reflect units rendered within each week up to the weekly medically necessary limit approved by prior approval; units above it are ineligible for reimbursement and will be adjusted. The affected codes are the full set — 97151, 97152, 0362T, 97153, 97154, 97155, 97156, 97157, 97158 and 0373T, each per 15 minutes. That article is the closest thing to a code-level public statement of what Anthem Ohio commercial authorizes, since the precertification list itself names ABA only as a category.[9][11]
Alongside it, note the criteria change. Anthem told Ohio commercial providers that effective June 1, 2024 it would transition from CG-BEH-02 (Adaptive Behavioral Treatment) and MCG W0153 to MCG B-806-T, Behavioral Health Care Applied Behavioral Analysis, for medical necessity and clinical appropriateness reviews. If your templates or a denial letter still reference CG-BEH-02, they are out of date. MCG guidelines are proprietary and unpublished, so leverage comes from a complete, data-anchored treatment plan rather than from quoting criteria back.[9][11]
The questions that decide whether a family can start with Anthem BCBS Ohio, and what they have to bring. Each maps onto something intake should ask on the first call.
Ohio writes this into the mandate rather than leaving it to the carrier. R.C. 3923.84(C)(2)(b) makes coverage contingent on the services being "prescribed or ordered by a psychologist trained in autism, a developmental pediatrician, or a clinical nurse specialist or certified nurse practitioner specializing in pediatric health." The nurse pathway is recent — Senate Bill 196 added it effective March 20, 2025 — and it widens the pool of clinicians who can legitimately order ABA in Ohio. Capture who wrote the order and their credential at intake.[1]
Yes — and unusually it is statutory rather than contractual. R.C. 3923.84(C)(2) makes coverage contingent on both prior authorization and the services being prescribed or ordered by a psychologist trained in autism, a developmental pediatrician, or a pediatric clinical nurse specialist or certified nurse practitioner. On the carrier side, Anthem’s precertification list for Ohio (shared with Indiana, Kentucky, Missouri and Wisconsin, updated January 1, 2026) lists applied behavioral analysis under behavioral health services with Anthem as the responsible party, and a separate row for treatment of autism spectrum disorder; since September 1, 2025 the preferred channel is Availity Essentials. One National Accounts nuance can change the whole workup: precertification for ABA "is recommended and applies unless the group specifically opts out of clinical review for this benefit," and retrospective review is allowed — if the card says National Accounts, call before building the file.[1][6][7]
Anthem treats telehealth as a place of service rather than a code restriction: its ABA provider resource guide names POS 10 for telehealth with the member at home and POS 02 for telehealth with the member elsewhere, alongside 12 home, 11 office or clinic, 99 community and 03 school — each subject to the member’s coverage and plan review. No Ohio-specific per-code telehealth limit is published. Since January 1, 2026 the reimbursement constraint that matters in Ohio is weekly rather than modal: claims must reflect units rendered within each week up to the weekly medically necessary limit approved on the prior approval, across 97151, 97152, 0362T, 97153, 97154, 97155, 97156, 97157, 97158 and 0373T.[8][9]
Anthem publishes no age cap for ABA in Ohio. What the statute does is set floors for a defined cohort: R.C. 3923.84 requires at least twenty hours a week of clinical therapeutic intervention, twenty speech and twenty occupational therapy visits a year, and thirty outpatient mental or behavioral health visits a year for an insured under the age of fourteen. Above fourteen those floors drop away, but the non-limiting clause at subsection (C)(1) and the parity clause at subsection (A) remain, so an over-14 request is a medical-necessity conversation rather than a coverage exclusion. The mandate itself does not reach non-grandfathered individual and small group plans, and self-funded ERISA plans sit outside state insurance law entirely.[1]
Ask the plan: Benefits verification on the member ID — settle the market segment first (large-group fully insured, individual or small group, or self-funded ERISA), then the plan’s own age and benefit terms.
For insured Ohio plans the state clock is faster than the federal floor. When the request is submitted electronically, the insurer “shall respond to all prior authorization requests within forty-eight hours for urgent care services, or ten calendar days for any prior authorization request that is not for an urgent care service, of the time the request is received” (R.C. 3923.041 for sickness-and-accident insurers and public employee benefit plans; R.C. 1751.72 for health insuring corporations). An incomplete request must get a reply naming the missing information. Plans outside those statutes, such as a self-funded private employer plan, are held to the federal floor: pre-service decisions “not later than 15 days after receipt of the claim,” one 15-day extension, and urgent care “not later than 72 hours after receipt” (29 CFR 2560.503-1). The same floor applies to non-grandfathered individual and marketplace plans (45 CFR 147.136).[13][14][15][16]
Ask the plan: Anthem Blue Cross and Blue Shield / Carelon Behavioral Health (number on the member ID card): whether the plan is insured in Ohio (R.C. 3923.041 / 1751.72 apply), self-funded (ERISA floor) or grandfathered; the plan’s own standard and urgent turnaround for ABA; and how far ahead of expiry a reauthorization must be filed.
Ohio’s COB rule sets the order for a child on both parents’ plans: “The plan of the parent whose birthday falls earlier in the calendar year is the primary plan”; if the birthdays match, the plan that has covered a parent longer goes first. For parents who are divorced, separated or not living together, a court decree assigning health costs controls. Without one, the order is the custodial parent’s plan, then the custodial parent’s spouse’s, then the non-custodial parent’s, then the non-custodial parent’s spouse’s (OAC 3901-8-01). That rule governs contracts issued in Ohio. Whether a self-funded employer plan follows it or its own plan document’s COB clause is a question for that plan. Public coverage pays after this plan. Ohio Medicaid “must be the last payer” (OAC 5160-1-08). TRICARE “pays after all other health insurance, except for” Medicaid. CHAMPVA “is always the secondary payer, except to Medicaid.” If this plan denies because its rules were not followed, including its prior authorization, TRICARE “may also deny the claim.” So get this plan’s authorization even when a public program is secondary.[17][18][19][20]
Ask the plan: Ask the family for both parents’ cards and birth dates, and ask the employer or HR whether each plan is fully insured and issued in Ohio (OAC 3901-8-01 order applies) or self-funded (the plan document’s COB clause applies).
Not published. Anthem moved Ohio commercial ABA reviews from CG-BEH-02 and MCG W0153 to MCG B-806-T effective June 1, 2024, and MCG guidelines are proprietary and unpublished, so any diagnosis-recency expectation lives inside criteria the clinic cannot read. The one statutory cadence that is public runs the other way: outside inpatient services the insurer may review the treatment plan annually, and no more often without the treating clinician’s agreement.[11][1]
Blocked on: A pre-service call to Anthem behavioral health (or a peer-to-peer) asking what MCG B-806-T expects on the age of the diagnostic evaluation — a denial letter still citing CG-BEH-02 is working from a retired document.
Not published. Neither R.C. 3923.84 nor Anthem’s Ohio precertification list or ABA provider resource guide names a diagnostic instrument, and the operative medical-necessity criteria — MCG B-806-T since June 1, 2024 — are proprietary and unpublished. Leverage in Ohio therefore comes from a complete, data-anchored treatment plan rather than from quoting instrument criteria back.[1][8][11]
Blocked on: A pre-service call or peer-to-peer with Anthem behavioral health asking which instruments MCG B-806-T expects behind the ASD diagnosis.
Coverage decides whether Anthem BCBS Ohio 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.
Anthem publishes no numeric supervision ratio for Ohio. What it does publish is a staffing rule with teeth: ABA delivered by therapy assistants, behavior technicians or paraprofessionals must show the supervising BCBA or other qualified health care professional in box 31 of the CMS-1500, with degree-level modifiers HM, HN and HO identifying the rendering staff level. Ohio then narrows who the supervisor can be — R.C. 3923.84 conditions mandated ABA on delivery by or under the supervision of a Certified Ohio Behavior Analyst, a Chapter 4732 psychologist, or a Chapter 4757 counselor, social worker or marriage and family therapist, and R.C. 4783.02 exempts technician-level staff from certification only while they are supervised by and acting under the authority and direction of a COBA. A BACB certificant without the COBA cannot supervise in Ohio.[8][1][3]
A physician or other QHP billing 97155 can add 97153 only if both the technician and the QHP are face-to-face with the patient at the same time and the QHP is directing the technician. Supervised or directed services billed alongside a QHP-performed procedure are also subject to Anthem's Incident To Services and Billing reimbursement policy.[8]
Anthem publishes no Ohio-specific per-day unit ceiling. From January 1, 2026 the binding limit is the weekly approved units on the authorization — units above the approved weekly figure are ineligible for reimbursement and adjusted. ABA codes may separately carry CMS MUE limits, administered as NCCI edits under Anthem's Code and Clinical Editing Guidelines reimbursement policy. Note that the state mandate's 20 hours per week for insureds under 14 is a statutory floor, not a ceiling.[9][1]
Each medical-record entry must carry author identification — handwritten signature, unique electronic identifier, or initials — plus rendering provider credentials. Entries are expected at the time of service or shortly thereafter and should not exceed 30 days, with a signature date within 30 days of the date of service. Timed codes require total treatment minutes plus start and stop times. Treatment plans must show review or update at least every 6 months; separately, Ohio law lets the insurer review the treatment plan annually, and no more often without the treating clinician's agreement.[8][1]
POS codes Anthem names for ABA: 12 home, 11 office/clinic, 99 community, 03 school, 10 telehealth with the member at home, 02 telehealth with the member elsewhere — each subject to the member's coverage and plan review.[8]
ABA delivered by therapy assistants, behavior technicians or paraprofessionals must show the supervising BCBA or other QHP in box 31 of the CMS-1500, with degree-level modifiers HM, HN and HO identifying the rendering staff level. In Ohio the supervising clinician must be a Certified Ohio Behavior Analyst, a Chapter 4732 psychologist, or a Chapter 4757 counselor, social worker or marriage and family therapist; technician-level staff are exempt from certification only while acting under a COBA's authority and direction.[8][1][3]
No — that is the most common misreading of R.C. 3923.84. Twenty hours a week of clinical therapeutic intervention is the minimum the statute requires for an insured under age fourteen, and the same section says it "shall not be construed as limiting benefits that are otherwise available to an insured under a policy." Ask for what is medically necessary; the 20 hours is the floor you can insist on, not the ceiling you must accept.
Non-grandfathered plans in the individual and small group markets are carved out by name, along with Medicare supplement, accident-only, specified disease, hospital indemnity, disability income, long-term care and other limited-benefit policies. Self-funded ERISA plans sit outside state insurance law entirely. Those members may still have an ABA benefit, but not because of R.C. 3923.84.
The statute makes coverage contingent on the services being prescribed or ordered by a psychologist trained in autism, a developmental pediatrician, or — since Senate Bill 196 took effect on March 20, 2025 — a clinical nurse specialist or certified nurse practitioner specializing in pediatric health. Prior authorization is likewise written into the mandate as a condition of coverage.
Yes. Ohio requires a Certified Ohio Behavior Analyst certificate from the State Board of Psychology to practise applied behavior analysis, and the COBA application itself requires current BACB certification. Staff working under a COBA's authority and direction, and family members implementing a plan, are exempt from certification — Ohio does not separately license technicians.
Outside inpatient services the statute lets the insurer review the treatment plan annually, unless the insurer and the treating physician, clinical nurse specialist, certified nurse practitioner or psychologist agree more frequent review is necessary — and the insurer covers the cost of obtaining the review or plan.
MCG B-806-T. Anthem notified Ohio commercial providers that effective June 1, 2024 it would move from CG-BEH-02 and MCG W0153 to MCG B-806-T for medical-necessity and clinical-appropriateness reviews. MCG guidelines are proprietary and unpublished, so a denial letter still citing CG-BEH-02 is working from a retired document.
