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][12][13][14][15]
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][12][13][14][15]
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).[16][17][11][5][7]
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]
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][21][22][23][24]
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.
Supervision and family training by video are payable once the provider is "an approved Optum virtual visits provider who has attested," billed on 97155 or 97156 with POS 02 (POS 10 is listed for telehealth in the member’s home). Optum’s criteria point to CASP’s telehealth parameters — telehealth is "not intended to supplant in-person service" — and the CASP guidelines allow in-person, telehealth or hybrid delivery. Whether technician-delivered 97153 is payable remotely is not stated.[5][1][3]
Ask the plan: Optum ABA clinical team 1-866-830-0325 — whether 97153 by telehealth is approvable and whether POS 10 applies to 97155/97156.
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][18][19][20]
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]
Allowed: "When supervision is provided, you may bill concurrently for both Supervisors and Behavior Technicians, billing with 97153 and 97155" — the same for 97154 with 97155, and 97153 with 97156 are "separate and distinct services" that "may be billed concurrently." Team meetings are billable only as supervision with the member, supervisor and technician present.[5]
"For our commercial ABA program MUE’s apply, per the CMS guidelines … Optum allows 32 units per day of 97151." No weekly hour cap in the criteria — hours are justified by clinical need, and CASP 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.[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.
