UnitedHealthcare commercial behavioral health — ABA included — is managed by Optum, and in California by U.S. Behavioral Health Plan, California, doing business as OptumHealth Behavioral Solutions of California, a DMHC-licensed specialty plan. California is one of the few states where Optum publishes its own ABA criteria: Provider Express lists "California Commercial – Applied Behavior Analysis" as the Council of Autism Service Providers (CASP) ABA Practice Guidelines, and Optum’s ABA State Mandates document carries a California entry that overrides parts of the national criteria. UnitedHealthcare runs no Medi-Cal plan in 2026.
Provider Express’s "State-Specific Clinical Criteria" — criteria "used to make medical necessity determinations … when there are explicit mandates or contractual requirements outside of the Criteria above" — list "California Commercial – Applied Behavior Analysis: The Council of Autism Service Providers (CASP) Applied Behavior Analysis Practice Guidelines for the Treatment of Autism Spectrum Disorder" (3rd ed., 2024). Separately, Optum’s national ABA criteria say California Commercial’s State Mandates entry applies "along with this set of criteria," and "To the extent this criteria conflicts with applicable state-mandated criteria, the state-mandated criteria controls." Optum’s documents do not say outright which set is the working test for a given member — ask at the first review.[4][3][2][1]
The California entry in Optum’s ABA State Mandates document (BH 803ABA STM72026, effective July 2026) says a plan "shall not limit benefits or coverage for medically necessary services on the basis that those services should be or could be covered by a public entitlement program, including, but not limited to, special education or an individualized education program, Medicaid," and that BHT "is administered by a qualified autism service professional to include a psychological associate, an associate marriage and family therapist, an associate clinical social worker, or an associate professional clinical counselor." For California commercial members that overrides the national exclusion of IDEA-covered services — a school IEP alone is not a reason to deny. CASP’s guidelines add that intensity decisions "should not be based on the length of time receiving treatment and/or the age of the individual," and "Evidence of failure at a lower level of service intensity should not be required to access a higher intensity of care."[4][3][2][1]
California’s mandate is Health & Safety Code § 1374.73 for DMHC-regulated health care service plans (every HMO and many PPO/EPO products) and Insurance Code § 10144.51, its word-for-word twin for CDI-regulated insurance policies. Enacted by SB 946 in 2011 with a sunset, made permanent by AB 796 in 2016 and last amended by SB 402 (effective January 1, 2026), it requires every plan covering hospital, medical or surgical care to cover "behavioral health treatment for pervasive developmental disorder or autism" — defined to include "applied behavior analysis and evidence-based behavior intervention programs" — "in the same manner and … subject to the same requirements" as mental health parity under § 1374.72. The statute has no age limit and no dollar or visit cap. Treatment must be "prescribed by a physician and surgeon" or "developed by a psychologist," follow a treatment plan with measurable goals "reviewed no less than once every six months" by the qualified autism service provider, and may not be used for "respite, daycare, or educational services." Plans may still use "case management, network providers, utilization review techniques, prior authorization, copayments, or other cost sharing."[9][10][14][15][16][17]
Three newer layers matter at intake. SB 855 (§§ 1374.72, 1374.721; Ins. §§ 10144.5, 10144.52) requires medical-necessity decisions under "generally accepted standards," using the criteria of "the nonprofit professional association for the relevant clinical specialty," supplied "at no cost" — and bars limiting coverage because services "should be or could be covered by a public entitlement program, including … special education or an individualized education program, Medicaid." SB 402 (carrying AB 951) says a contract issued, amended or renewed on or after January 1, 2026 "shall not require an enrollee previously diagnosed with pervasive developmental disorder or autism to receive a rediagnosis to maintain coverage" and "shall not discontinue or delay existing treatment while waiting for a rediagnosis." And every plan must keep "an adequate network" of qualified autism service providers. Exempt: self-funded ERISA employer plans (outside state law — the California-specific Optum criteria likely do not reach them), Medi-Cal plan contracts, specialized plans that do not deliver mental health services, and — for CDI policies — accident-only, specified-disease, hospital-indemnity and Medicare supplement policies.[9][10][14][15][16][17]
California has no behavior analyst license — it is absent from the BACB’s licensure table, and SB 402’s new Business & Professions Code chapter (§§ 4999.200–4999.202) is definitional only. A qualified autism service (QAS) provider is a BCBA ("certified by a national entity, such as the Behavior Analyst Certification Board") or a listed California licensee; a QAS professional (BCaBA-level behavior service providers under 17 CCR § 54342, or — since SB 805 — associate MFTs, ACSWs, APCCs and psychological associates) works under the provider’s supervision; and a QAS paraprofessional — the technician — is "an unlicensed and uncertified individual" supervised "at a level of clinical supervision that meets professionally recognized standards of practice." Optum still expects 1:1 technicians to hold an RBT, BCAT or ABAT credential (or an approved alternative) and credentials BCBAs with six months’ supervised ABA experience. Optum publishes no commercial ABA fee schedule; request yours from the Provider Service Line (1-877-614-0484).[18][19][11][5][7]
UnitedHealthcare commercial ABA is managed by Optum Behavioral Health, which publishes no ABA rate table. Optum's ABA FAQ tells contracted providers to "bill your contracted billing codes and customary charges as outlined on your Fee Schedule after receiving appropriate authorization. You will be reimbursed based on your contracted rate." The fee schedule is the one attached to your Optum agreement; non-contracted providers get approvals through the behavioral-health number on the member's card.[5]
Joining the network: Optum lists credentialing and contracting criteria for ABA providers (BCBA with active certification, state licensure where the state licenses behavior analysts, six months of supervised ABA experience, and professional liability of $1 million per occurrence) and takes applications through the "Join Our Autism/ABA Network" section of its ABA page on Provider Express. Credentialing "can take from 45 to 120 days after submission of all materials," every new agency gets a site audit that can take up to 90 days to schedule, and a single case agreement while credentialing is "Not automatically" available, only in exception cases such as a network gap. Technicians working 1:1 must hold RBT, BCAT or ABAT certification (or an approved alternative).[5]
The questions that decide whether a family can start with UnitedHealthcare in California, and what they have to bring. Each maps onto something intake should ask on the first call.
No expiry on the diagnosis. Optum: "Updated evaluations may target specific skill deficits and are not required to be comprehensive unless there is a question about an individual’s autism spectrum disorder diagnosis"; the request checklist asks for the diagnosing clinician and date. On fully insured California plans renewed on or after January 1, 2026, § 1374.73(c) bars requiring a rediagnosis to maintain coverage.[5][6][9]
"A state licensed physician, psychologist, or other state licensed clinician qualified to make such diagnosis according to … DSM-5-TR" (Optum criteria). Psychologist diagnostic testing is billed under Optum’s general behavioral health network, not the autism contract.[1][5]
Optum’s three-tier, non-exhaustive list: screening (ABC, CHAT/M-CHAT, CSBS-DP-IT, ASQ, AQ, CAST), second-level (CARS/CARS-2, RITA-T, STAT), formal diagnostic (ADI-R, ADOS/ADOS-2, DISCO), plus baseline and intensity tools (ATEC, VB-MAPP, ABLLS/ABLLS-R, AFLS, PEAK, SSIS, RBS-R, SRS, Vineland, CFQL-2).[1]
No physician referral or order in Optum’s criteria or FAQ; coordination with the diagnosing physician or psychologist is expected. On fully insured California plans the mandate keys covered BHT to a physician prescription or a psychologist-developed plan, so collect one.[1][5][9]
Three codes, after an attestation. Optum’s Telehealth Billing guide (updated September 2025) is explicit for commercial plans: “For ABA services, telehealth is only allowed for these 3 CPT codes: 97155, 97156 or 97157” — virtual supervision of technicians and family training — so technician-delivered 97153 is not payable by telehealth. The provider must first be “an approved Optum virtual visits provider who has attested” (the virtual-visits attestation on Provider Express) and must tell the ABA Care Advocate at authorization. Bill the in-person code with the member’s location as the place of service: POS 10 when the member is at home, POS 02 anywhere else (the older ABA CPT FAQ says POS 02; the 2025 guide requires one of the two on every behavioral-health telehealth claim, and POS 11 or a telehealth modifier alone is not paid). Optum’s criteria add that telehealth is “not intended to supplant in-person service.” The CASP guidelines Optum posts as its California commercial criteria allow in-person, telehealth or hybrid delivery. The assessment is not on that list: 97151 (initial assessment and reassessment) and 97152 are not payable by telehealth for commercial members, so plan the assessment in person. Supervision is: 97155 is billed with the in-person code and POS 02 or 10 after the attestation (Optum's ABA FAQ, Q29), and Optum publishes no minimum in-person share of supervision.[13][5][1][3]
Optum’s FAQ: if the member has no ABA benefit on one plan, "Call the number on the back of the member’s insurance card to request a denial" for the secondary carrier. Its California mandate entry bars limiting coverage because services "could be covered by a public entitlement program, including … Medicaid" — so UHC pays ahead of Medi-Cal, which is payer of last resort (W&I § 14124.90). Between two parents’ plans, California’s regulators apply the birthday rule (28 CCR § 1300.67.13; 10 CCR § 2232.56). TRICARE pays after this plan (10 U.S.C. 1079(i)(1)); CHAMPVA is "the last payer" (38 CFR 17.270(b)).[5][2][23][24][25][26]
No age criterion in Optum’s national ABA criteria, its California mandate entry or the CASP guidelines (decisions "should not be based on … the age of the individual"). H&S § 1374.73 / Ins. § 10144.51 contain no age or dollar limit for fully insured plans; self-funded plans follow their plan document.[1][3][9]
Ask the plan: Benefits verification on the member ID — fully insured vs. self-funded, then the plan’s own terms.
Optum publishes no ABA decision clock; continued-care requests go in "no more than 30 days prior to the current approvals on file expiring," and reviews run every 4–6 months. The regulator’s clock applies: DMHC plans (including Optum’s California entity), H&S § 1367.01(h) — "not to exceed five business days" from receipt of the information reasonably necessary, 72 hours urgent; CDI policies, Ins. § 10123.135(h), the same; self-funded ERISA plans, 29 CFR 2560.503-1 — 15 days pre-service, one 15-day extension, 72 hours urgent.[5][20][21][22]
Ask the plan: At benefits verification ask whether the plan is DMHC, CDI or self-funded, then confirm the turnaround with the Optum ABA clinical team (1-866-830-0325).
Coverage decides whether UnitedHealthcare in California 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.
Optum’s April 2026 criteria: "Consistent with CASP standards of care, direct case supervision is required 1–2 hours for every 10 hours of direct treatment per week"; the FAQ says requests above 2:10 need a clinical rationale. Technicians "should be registered behavior technicians (RBT) or another appropriately certified behavior technician as allowable by state mandate," and BCaBAs may supervise as BCBA extenders. For California, Optum’s mandate entry lets associate-level QAS professionals administer treatment, and CASP says funders "should not restrict case supervision to the established minimum."[1][5][2][3]
Yes, with a single-provider exclusion. Optum’s commercial ABA reimbursement policy: “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 has to be two people — a technician on 97153 and an analyst on 97155 directing them with the patient present. Optum’s ABA CPT FAQ adds that 97153 and 97156 “may be billed concurrently” as separate services to different family members by different providers. 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.” Team meetings bill only as supervision with the member, supervisor and technician present, and “CPT codes 97153 and 97155 may not be billed for technician training.”[12][5]
Optum’s commercial ABA reimbursement policy (2022RP501A, updated June 2026) sets a maximum frequency per day for every code: 97151 32 units (8 hrs), 97152 16 (4 hrs), 97153 32 (8 hrs), 97154 18 (4.5 hrs), 97155 24 (6 hrs), 97156 16 (4 hrs), 97157 16 (4 hrs), 97158 16 (4 hrs), 0362T 16 (4 hrs), 0373T 32 (8 hrs) — and “If a provider bills in excess of 32 units per day, claims may be subject to non-reimbursement or recovery.” The ABA CPT FAQ confirms “For our commercial ABA program MUE’s apply.” There is no weekly hour cap: hours are authorized on documented clinical need, approved units can be shifted among codes within a cluster, and utilization below 80% of authorized hours over a two-week period is addressed at review. CASP, which Optum posts as its California commercial criteria, says intensity is “independent of the patient’s schedule of activities outside of treatment.” Two technicians on the same day combine onto one 97153 line; one copay per date of service.[12][5][3]
"Provider signature is required on progress notes. Parent/guardian signatures are not required." Daily notes carry place of service, start and stop time, who rendered, the service, who attended, interventions and credentials; Optum’s June 2026 documentation protocol adds "The date of signature must reflect the date the note is finalized," with late entries following late-entry rules, and 97155 notes must name the technician and any protocol modification.[5][8]
POS 12 home, 11 clinic, 99 community, 03 school, 10/02 telehealth. School-based requests need school type, hours, IEP information and goals. Nationally Optum excludes a 1:1 aide during class and IDEA-covered services, but for California commercial members its State Mandates entry bars limiting coverage because services "could be covered by … special education or an individualized education program," and "the state-mandated criteria controls."[5][6][2]
Yes — through Optum Behavioral Health, for autism, with prior authorization on every ABA service. Fully insured California plans also fall under the state mandate and Optum’s California-specific criteria.
Not on that basis alone for California commercial members: Optum’s California State Mandates entry and H&S § 1374.72(h) bar limiting coverage because special education, an IEP or Medicaid could provide the service.
No — no UnitedHealthcare Medi-Cal plan operates in any county in 2026. Medi-Cal ABA runs through the county Medi-Cal plan.
Optum, which manages UnitedHealthcare’s behavioral health benefits, says “At a minimum, most treatment reviews are required every 4-6 months depending on the account/state law.” Call in the continued-care request “no more than 30 days prior to the current approvals on file expiring,” with updated progress data measured the same way as baseline and updated standardized measures. There is no fixed reassessment frequency (“There is no required frequency at which an assessment must take place”) — ask for reassessment hours inside the treatment request. If more hours are needed mid-authorization, call the ABA team with a clinical rationale. On fully insured California plans the treatment plan must be “reviewed no less than once every six months” by the qualified autism service provider.
Supervision yes, assessment no. For commercial plans Optum allows telehealth only on 97155, 97156 and 97157, after a virtual-visits attestation, billed with POS 02 or 10. The 97151 assessment is not on that list.
There is no public one. Optum pays contracted providers at the rate on the fee schedule in their Optum agreement.
Optum takes ABA applications through the "Join Our Autism/ABA Network" section of Provider Express. Credentialing takes 45 to 120 days after a complete submission, plus a site audit for new agencies. Optum publishes no statement that its network is closed.
