# UnitedHealthcare / Optum ABA coverage in Vermont: the intake guide.

_Payer Guide · UnitedHealthcare · Vermont · Last updated October 2026 · 18 primary sources_

> Optum criteria (BH803ABASCC) + Vermont’s § 4082 mandate; no Vermont state supplement; Vermont has no Medicaid MCOs.

UnitedHealthcare is not one of Vermont’s individual or small-group carriers (regulators name Blue Cross VT and MVP), and Vermont has no Medicaid health plans at all. So a UnitedHealthcare card in Vermont is an employer plan (often national and self-funded) or Medicare. Funding decides whether Vermont’s mandate applies.

The layers: Optum Behavioral Health’s national ABA criteria, Vermont’s mandate in 8 V.S.A. § 4082, and Vermont’s claims and licensure laws.

## Prior authorization and diagnosis at a glance

- **Prior auth for the assessment**: Required: the ABA Supplemental Clinical Criteria say prior authorization is required for ABA "unless otherwise specified or mandated by contract or law" [1]
- **Prior auth for treatment** _(plan-dependent)_: Required: treatment authorization under the same criteria; the review interval is set per authorization [1]
  - Ask the plan: Optum Provider Express or the behavioral health number on the card: ask what review interval will be set on this member’s ABA treatment authorization.
- **Autism diagnosis required?**: Yes: DSM-5-TR ASD (or another diagnosis required by governing law) from a state-licensed clinician, confirmed with at least one clinically validated tool [1]

## At a glance

- **Covers ABA?:** Yes, for ASD, per Optum’s ABA Supplemental Clinical Criteria
- **State mandate:** 8 V.S.A. § 4082 (formerly § 4088i; recodified by Act 11 of 2025, eff. 9/1/2025)
- **Mandate age:** Birth until age 21
- **Mandate caps:** No dollar or hour cap; amount, frequency and duration by medical necessity, PA allowed; need not exceed ACA essential health benefits
- **Exempt from mandate:** Self-funded ERISA employer plans (the statute reaches self-insured administrators only "to the extent permitted under federal law")
- **Licensure:** Yes: OPR licenses applied behavior analysts and assistant behavior analysts (26 V.S.A. ch. 95)
- **Fee schedule:** Not public — Optum pays up to the “Fee Maximum” in your agreement, by credential level (HM/HN/HO/HP modifiers)

## The national policy, applied in Vermont

UnitedHealthcare administers ABA through Optum Behavioral Health under the ABA Supplemental Clinical Criteria (BH803ABASCC; interim review April 2026). Prior authorization is required "unless otherwise specified or mandated by contract or law." The diagnosis must come from a state-licensed clinician using at least one validated tool. Direct case supervision runs 1–2 hours per 10 hours of treatment. Optum’s ABA State Mandates supplement lists states such as Arizona, California, Connecticut, Florida, Massachusetts, New Jersey, New York, Ohio, Pennsylvania and Virginia, but not Vermont, so no Vermont-specific criteria modify the commercial policy. Optum’s National Network Manual (effective Sept. 1, 2026) carries a set of Vermont Regulatory Requirements for network providers. [1][2][3][17]

## The Vermont mandate: what it guarantees

Vermont’s autism mandate is 8 V.S.A. § 4082, "Early childhood development disorders." It is the old § 4088i under a new number: Act 11 of 2025 recodified Title 8’s health insurance chapter effective September 1, 2025, so plan documents and carrier policies that still cite § 4088i are pointing at the same law. The statute says a health insurance plan "shall provide coverage for the evidence-based diagnosis and treatment of early childhood developmental disorders, including applied behavior analysis supervised by a nationally board-certified behavior analyst, for children, beginning at birth and continuing until the child reaches 21 years of age." The disorders covered are broader than autism: any childhood impairment with functional limits and a DSM or ICD diagnosis, "but does not include a learning disability." The statute sets no dollar or hour cap. Instead, "the amount, frequency, and duration of treatment … shall be based on medical necessity and may be subject to a prior authorization requirement." Cost sharing may not be higher than for any other physical or mental condition. ABA must be covered when "provided or supervised by a licensed health care professional … or who is a nationally board-certified behavior analyst," including in the "natural environment" (a home or child care setting). Plans may review the treatment plan "based on the needs of the covered individual," but for children under eight "not more frequently than once every six months." Two limits matter. A major medical plan does not have to provide benefits beyond the ACA essential health benefits. And the statute leaves IEP and early-intervention obligations in place: a plan "shall not reimburse services provided under 16 V.S.A. § 2959a." On who is bound: chapter 107 defines a health insurer to include an HMO, a nonprofit hospital or medical service corporation and, "to the extent permitted under federal law, any administrator of an insured, self-insured, or publicly funded health care benefit plan." The State of Vermont employee plans are expressly included. Self-funded private employer plans follow ERISA, so check how the plan is funded first. [6][7]

## Licensure and out-of-state BCBAs

Vermont licenses behavior analysts. Under 26 V.S.A. chapter 95, administered by the Office of Professional Regulation, a person may not practice "as an applied behavior analyst or an assistant behavior analyst unless currently licensed." A BCBA can get a license by endorsement on the strength of BACB certification alone (§ 4923). Three rules shape the work. A licensee may practice only "upon, and within the scope of, a referral from a licensed health professional or school official." Diagnosis is outside the scope: behavior analysis "shall not include … diagnosis of mental health or developmental conditions" (§ 4928). And a licensed assistant behavior analyst needs at least "five hours per month of off-site case supervision" by a licensed behavior analyst (§ 4929). Technicians are not licensed. The chapter does exempt school-employed paraprofessionals working "under the close direction" of a licensed supervisor, and people employed by or under contract with the Agency of Human Services. For BCBAs outside Vermont, 26 V.S.A. chapter 56 lists applied behavior analysis among the professions eligible for out-of-state telehealth credentials. A telehealth license covers up to 20 unique Vermont clients over a two-year term. A telehealth registration covers up to 10 clients over 120 days and cannot be renewed. Either one allows telehealth only, never in-person care. Both require a credential "in good standing in any other U.S. jurisdiction." BACB certification is not issued by a jurisdiction, so read literally, a BCBA from a state that does not license behavior analysts needs the full Vermont license by endorsement. Treating a Vermont client by telehealth without one of these credentials is unauthorized practice. [9][10][19][11]

## Claims operations: prompt pay, prior-authorization clocks, appeals

Vermont’s claims and prior-authorization rules bind health plans, defined to include insurers, HMOs and, "to the extent permitted under federal law, any administrator of an insured or self-insured plan." Under the prompt-pay statute (18 V.S.A. § 9418), a plan must pay a claim, or notify you in writing that it is contested or denied, within 30 days of receipt. It must acknowledge an electronic claim within 24 hours after the start of the next business day. Unpaid uncontested claims accrue interest at 12 percent a year. The prior-authorization statute (18 V.S.A. § 9418b, as amended through 2025) sets the timeline. A completed non-urgent request must be decided "within two business days following receipt," and receipt acknowledged within 24 hours. Urgent requests are decided within 24 hours. A missed deadline means the request "shall be deemed to have been granted." An approval lasts "for the duration of the prescribed or ordered treatment … or one year, whichever is longer," and for ongoing treatment a plan may not require renewal more often than every five years. The mandate separately lets plans review an ABA treatment plan (every six months at most for children under eight), so ask how the carrier squares the two. Plans may not require prior authorization for services ordered by an in-network primary care provider (out-of-network services excepted). Plans must also post their current prior-authorization list publicly. A self-funded ERISA plan follows 29 CFR 2560.503-1 instead: pre-service decisions within 15 days (one 15-day extension), urgent ones within 72 hours, and at least 180 days to appeal a denial. After internal appeals, Vermont’s external review (8 V.S.A. § 4063) is open for medical-necessity and experimental denials involving at least $100, for a $25 fee. [12][13][6][16][14]

## What is UnitedHealthcare’s fee schedule for ABA?

UnitedHealthcare publishes no ABA rate table; Optum pays from the contract. Its National Network Manual defines the "Fee Maximum" as "the maximum amount a participating provider may be paid for a specific health care service provided to a member," and says "Reimbursement to clinicians is based upon licensure rather than degree." Optum’s commercial ABA Reimbursement Policy (2022RP501A, updated June 2026) puts the credential on every line: HM for an RBT, HN for a BCaBA, HO for a master’s-level BCBA or licensed clinician, HP for a doctoral-level provider. It notes that state requirements "may supplement, modify or supersede" the policy. Ask Optum network management for your rate sheet. For a public benchmark, Vermont Medicaid’s fee-for-service schedule pays 97153 at $15.00 and 97155 at $49.35 per 15 minutes. [3][5][18]

## UnitedHealthcare claim filing, ABA codes and reauthorization data

Optum’s National Network Manual (effective September 1, 2026), which governs the behavioral health claims Optum administers for UnitedHealthcare, sets the filing clock: “All information necessary to process claims must be received by Optum no more than 90 calendar days from the date of service, or as allowed by state or federal law or the member’s specific benefit plan,” and “Any corrections or additions to a claim should be made within 90 days of initial claim receipt.” Claims with all required information and any required authorization are generally paid “within 45 calendar days after Optum receives the claim, or as required by state and federal laws.” If Optum is secondary you are paid up to the Optum contracted rate; the manual sets no separate secondary-claim deadline and does not mention electronic visit verification. [3][5][1]

Optum’s commercial ABA reimbursement policy (2022RP501A, updated June 2026) lists CPT 97151–97158, each with a credential modifier (HM for an RBT, HN for a BCaBA, HO for a BCBA or licensed clinician, HP for a BCBA-D), plus 0362T and 0373T without modifiers. It lists no HCPCS H-codes such as H0031 or H0032, and says “97151 and 97152 are the only codes eligible for reimbursement for assessment or reassessment activities.” At each continued-treatment review, Optum’s ABA criteria ask for updated documentation showing progress “for each targeted symptom and behavior, including progress toward defined goals, including the same modes of measurement that were utilized for baseline measurement.” They do not require graphs as such. [3][5][1]

## Intake gates

The questions that decide whether a family can start with UnitedHealthcare / Optum in Vermont, and what they have to bring.

- **Diagnosis recency**: No expiry on the diagnosis; it must be confirmed with severity level using a validated tool. Progress is reviewed against baseline, and use below 80% of authorized hours triggers review. [1]
- **Who may diagnose**: A "state licensed physician, psychologist, or other state licensed clinician qualified to make such diagnosis" under DSM-5-TR. In Vermont a behavior analyst cannot diagnose (26 V.S.A. § 4928). [1][9]
- **Diagnostic tools required**: At least one clinically validated tool from a non-exhaustive list: first-level screens (M-CHAT and others), second-level screens (CARS/CARS-2, RITA-T, STAT) and formal diagnostic tools (ADI-R, ADOS/ADOS-2, DISCO). [1]
- **Referral required?**: No separate physician referral in the SCC; ABA requires prior authorization. Vermont’s licensure law adds its own gate: a Vermont-licensed behavior analyst may practice only "upon, and within the scope of, a referral from a licensed health professional or school official" (26 V.S.A. § 4928), so keep that referral on file whatever the plan requires. [1][9]
- **Age limit** _(plan-dependent)_: The SCC carry no age criterion; the member’s benefit plan governs. For fully insured Vermont plans, 8 V.S.A. § 4082 requires ABA coverage from birth until the child reaches 21, with no dollar or hour cap in the statute. Self-funded ERISA plans are outside it, so plan funding type decides whether that binds. [1][6]
  - Ask the plan: Provider Express benefits check or the behavioral health number on the card: establish fully insured vs. self-funded ERISA first.
- **Telehealth** _(plan-dependent)_: Three codes on commercial plans. Optum’s Telehealth Billing guide (updated September 2025): "For ABA services, telehealth is only allowed for these 3 CPT codes: 97155, 97156 or 97157." Claims must carry POS 02 or POS 10; a telehealth modifier alone is not paid. The SCC say telehealth is "not intended to supplant in-person service." For a fully insured Vermont plan, 8 V.S.A. § 4098a requires coverage of services delivered by telemedicine (live audio-video) "to the same extent" as in person, from any originating site including "the patient’s home," at the same rate for equivalent codes and modifiers (subject to the provider contract). A plan may still limit coverage to services that are "medically necessary and are clinically appropriate for delivery through telemedicine." Self-funded plans are outside the statute. Ask Optum how it applies the three-code list to a fully insured Vermont plan. The same guide lists telehealth modifiers 93, 95, FQ, GT and GQ as optional on commercial claims; the POS code is what is mandatory. [4][1][8]
  - Ask the plan: Optum Provider Express support or the behavioral health number on the card: confirm funding (fully insured in Vermont vs. self-funded) and which ABA codes Optum pays by telehealth for this member.
- **Prior-auth decision time** _(plan-dependent)_: Depends on funding. A plan subject to 18 V.S.A. § 9418b must decide a completed non-urgent request within two business days and an urgent one within 24 hours, or the request is deemed granted. Self-funded ERISA plans follow 29 CFR 2560.503-1 (15 days, one 15-day extension; urgent 72 hours). Optum publishes no Vermont-specific ABA turnaround. [13][16]
  - Ask the plan: At benefits verification ask whether the plan is fully insured in Vermont or self-funded (ERISA), and what reauthorization lead time Optum expects.
- **Other insurance (who pays first)** _(plan-dependent)_: No Vermont rule fixing the order of benefits between two parents’ group plans was confirmed this run, so take the order from UnitedHealthcare/Optum at benefits verification. A self-funded plan sets its own order. If the child also has Vermont Medicaid, UnitedHealthcare/Optum pays first. A Vermont insurer may not consider Medicaid eligibility when paying claims (8 V.S.A. § 4024), and Medicaid is the payer of last resort (42 CFR 433.139). Vermont Medicaid will cover what the primary plan denies only after you have used every level of the primary plan’s appeals and, where the service costs more than $100, a Department of Financial Regulation review. TRICARE pays after this plan (10 U.S.C. 1079(i)(1)); CHAMPVA is the last payer (38 CFR 17.270). [15][20][21][22][23]
  - Ask the plan: Ask UnitedHealthcare/Optum at benefits verification for the member’s coordination-of-benefits order, and record every other coverage the child has.

## Delivery and billing rules

Coverage decides whether UnitedHealthcare / Optum in Vermont 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**: "Consistent with CASP standards of care, direct case supervision is required 1–2 hours for every 10 hours of direct treatment per week." Technicians work under a BCBA or licensed behavioral health clinician and "should be registered behavior technicians (RBT) or another appropriately certified behavior technician as allowable by state mandate"; Optum does not recommend parents serving as their own child’s RBT. Vermont law adds five hours a month of off-site case supervision for a licensed assistant behavior analyst. [1][9]
- **Concurrent billing (97153 + 97155)**: Yes for two people, never for one. Optum’s commercial ABA reimbursement policy (2022RP501A, updated June 2026): “Can I report 97153 or 97154 with 97155 concurrently? A. Yes, as long as the criteria in the descriptors of both codes are met. A single QHP may not report 97153 or 97154 with 97155 concurrently.” So the overlap must be a technician on 97153 and an analyst on 97155 directing them with the patient present. 97155 and 97156 on the same date pay only if “separate, distinct, and clearly documented in the progress notes”; “A single provider can’t bill for both simultaneously (e.g., in the same 15-minute block).” 97155 is not payable for treatment planning while the technician works, and neither 97153 nor 97155 may be billed for technician training. Overlap with speech or OT is not addressed as a billing rule; the ABA criteria say ABA services “do not duplicate the services provided to or available to the individual by other medical or behavioral services” and ask for documented coordination with OT, speech and PT providers. [5][1]
- **Daily limits / MUEs**: Per-day maximums, enforced on the claim. Optum’s commercial ABA reimbursement policy (2022RP501A, updated June 2026) sets a maximum frequency per day for every code: 97151 32 units (8 hours), 97152 16 (4 hours), 97153 32 (8 hours), 97154 18 (4.5 hours), 97155 24 (6 hours), 97156 16, 97157 16, 97158 16, 0362T 16 and 0373T 32. It says “For commercial ABA program MUE’s apply, per CMS guidelines” and “If a provider bills in excess of 32 units per day, claims may be subject to non-reimbursement or recovery.” There is no weekly hour cap: requested hours must be justified by documented clinical need, and at continued-service review use below 80% of authorized hours over a two-week period must be explained with barriers and a plan. [5][1]
- **Place of service**: Not covered: services that are not ABA, "such as 1:1 aid delivered simultaneously during classroom instruction," or services covered under IDEA; school coordination is allowed. Vermont’s mandate requires coverage in the natural environment (home or child care). [1][6]
- **Bill as provider**: A credentialed ABA provider is a master’s- or doctoral-level BCBA or a licensed behavioral health clinician credentialed for ABA; a BCaBA or non-licensed staff member works under that provider’s direct supervision. Optum’s commercial reimbursement policy adds the credential modifier (HM RBT, HN BCaBA, HO, HP) to each line. In Vermont the behavior analyst must also hold a Vermont license. [1][5][9]
- **Session-note signature** _(ask the plan)_: Not addressed. The SCC set what must be documented for coverage, not who signs a session note or when. [1]
  - Ask the plan: Optum Provider Express National Network Manual (documentation standards) and the participating-provider agreement.

## What intake should collect for UnitedHealthcare / Optum in Vermont

- **Plan funding type:** Fully insured (8 V.S.A. § 4082 applies) vs. self-funded ERISA (plan document governs).
- **Member ID + card photo:** Enough to run a live benefits verification on Provider Express.
- **Diagnosis with a validated tool:** DSM-5-TR ASD and severity level, confirmed with a validated tool (ADI-R, ADOS-2 and others).
- **Referral:** Vermont-licensed behavior analysts practice only on a referral from a licensed health professional or school official.

## Common questions

### What is UnitedHealthcare’s timely filing limit for ABA in Vermont?

Optum, which administers UnitedHealthcare’s behavioral health claims, needs all claim information within 90 calendar days of the date of service unless state law, federal law or the benefit plan allows longer; corrections are due within 90 days of initial claim receipt.

### Does UnitedHealthcare accept H0031 or other H-codes for ABA?

Optum’s commercial ABA reimbursement policy lists only CPT 97151–97158 (with an HM, HN, HO or HP credential modifier), 0362T and 0373T. No H-codes are listed.

### How many units of 97153 can I bill per day with UnitedHealthcare?

Thirty-two units (8 hours). Optum’s commercial ABA reimbursement policy caps each code per day, and units over the maximum may be denied or recovered.

### Does UnitedHealthcare cover ABA therapy in Vermont?

Yes, under Optum’s national ABA criteria for ASD. Fully insured plans must also meet Vermont’s 8 V.S.A. § 4082 mandate (birth to 21, no dollar cap). Self-funded employer plans follow their own documents.

### Does Optum have Vermont-specific ABA criteria?

No. Optum’s ABA State Mandates supplement does not list Vermont, so the national criteria apply.

### Is UnitedHealthcare a Vermont Medicaid plan?

No. Vermont Medicaid has no managed care plans; DVHA authorizes and pays ABA directly.

### Can ABA be delivered by telehealth with UnitedHealthcare in Vermont?

Optum’s commercial telehealth guide allows only 97155, 97156 and 97157, billed POS 02 or 10. Fully insured Vermont plans are also subject to 8 V.S.A. § 4098a, which requires telemedicine coverage to the same extent as in person where clinically appropriate, so ask Optum how it applies the list to your plan.

### What does UnitedHealthcare pay for ABA in Vermont?

UnitedHealthcare/Optum publishes no ABA rates. You are paid up to the Fee Maximum in your Optum agreement, with a credential modifier on each line (HM RBT, HN BCaBA, HO BCBA, HP BCBA-D). Vermont Medicaid’s schedule (97153 $15.00 per 15 minutes) is the public benchmark.
