Blue Shield of California (California Physicians’ Service, a DMHC-licensed plan) is one of the state’s two Blue plans — separate from Anthem Blue Cross. The operational headline for 2026: Magellan is gone. Since January 1, 2026, Blue Shield manages behavioral health for its commercial HMO and PPO members directly, "including Applied Behavioral Analysis (ABA)," and took over ABA for self-funded and Shared Advantage plans too. Old Magellan faxes and portals are wrong for 2026 dates of service.
Blue Shield’s October 2025 provider webinar announced it "will begin directly managing Behavioral Health services members enrolled in commercial HMO and PPO plans … including Applied Behavioral Analysis (ABA)," replacing its mental health service administrator, Human Affairs International of California (Magellan); requests for dates of service from January 1, 2026 "must be submitted to Blue Shield, and will no longer be accepted by Magellan." The July 2026 provider manual confirms it. Policy BSC3.01 (effective December 1, 2025) still says ABA "must be prior authorized by Blue Shield’s mental health service administrator" — that wording is out of date.[5][2][6][7]
BSC3.01 requires an ASD or PDD diagnosis, a requested assessment ("The provider must request authorization for the initial assessment," with hours per CPT code and "A list of standardized assessments"; over 20 hours needs a "detailed explanation"), and for continued care "either an initial assessment or reassessment within the prior 12 months" plus baseline-versus-current data. Supervision is capped rather than floored: "no more than 2 hours of supervision for every ten (10) hours of direct service" unless a higher ratio is shown medically necessary. Hours "spent in educational settings and receiving IEP services should not be included in the calculation of treatment hours." Blue Shield applies nonprofit-association (SB 855) criteria for fully insured reviews, naming CASP’s ABA Practice Guidelines for ABA. For HMO members ABA is carved out of medical-group delegation — Blue Shield, not the IPA, authorizes and pays. Federal Employee Program members have their own form and rules.[5][2][6][7]
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."[8][9][13][14][15][16]
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), 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.[8][9][13][14][15][16]
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." Blue Shield "expects all network providers to comply with the changes made via SB 805." Blue Shield publishes no commercial ABA fee schedule; rates are negotiated in the participating agreement.[17][18][11][6]
Blue Shield’s July 2026 Independent Physician and Provider Manual: "you must submit your claims to Blue Shield within 12 months of the date of service(s) unless otherwise stated by contract"; claims filed later without an explanation may be denied, and members are not responsible for charges denied for late filing. Clean claims must identify the rendering provider.[1][6][19][20]
Provider disputes must be submitted "within 365 days, or the time specified in the provider’s Blue Shield agreement, whichever is greater," of Blue Shield’s contest, denial, notice or payment; Blue Shield acknowledges paper disputes within 15 working days (electronic within two) and "will resolve disputes within 45 working days." The DMHC rule underneath: no filing deadline shorter than 90 days for contracted providers (180 for non-contracted) and, since January 1, 2026, payment of a complete claim within 30 calendar days of receipt, with 15% annual interest from day 31 (H&S § 1371 as amended by AB 3275; the regulation’s 30 and 45 working days no longer control).[1][6][19][20]
If you are in Blue Shield’s network and the child’s card is from another Blue plan, Blue Shield of California is your claims door. The July 2026 manual says BlueCard lets professional providers "submit claims for patients from other state Blue Plans, either domestic or international, to Blue Shield of California," and "Blue Shield is your primary contact for BlueCard claims processing, provider correspondence, and inquiries." Paper claims and correspondence that need medical records go to Blue Shield of California, BlueCard Program, P.O. Box 272630, Chico CA 95927-2630, (800) 622-0632.[6]
Prior authorization follows the member’s home plan, not Blue Shield. Appendix 5-A tells providers to "remind patients that they are responsible for obtaining pre-certification/ authorization for outpatient services from their Blue plan," and that "Failure to obtain required prior authorization or admission review may result in partial or total benefit denial." To check or request it, use the Electronic Provider Access tool ("Pre-service review for out-of-area members" on Provider Connection). Entering the member’s three-character prefix routes you to the home plan’s portal. You can also call BlueCard Eligibility at (800) 676-BLUE (2583) and choose the Behavioral Health pre-certification option. The home plan may contact you directly for clinical information or records before treatment or for concurrent review.[6]
The questions that decide whether a family can start with Blue Shield of California, and what they have to bring. Each maps onto something intake should ask on the first call.
None. BSC3.01 sets no age criterion, and its rationale (quoting CASP) says comprehensive ABA "should not be limited by age." H&S § 1374.73 / Ins. § 10144.51 contain no age cap for fully insured plans; a self-funded plan’s own document governs.[2][8]
No expiry on the diagnosis in BSC3.01 or the request form; what is dated is the ABA assessment — continued care needs "an initial assessment or reassessment within the prior 12 months," and adaptive testing "should be administered every six (6) to twelve (12) months." For contracts issued or renewed on or after January 1, 2026, § 1374.73(c) bars requiring a rediagnosis to maintain coverage.[2][8]
A "licensed, qualified health care provider" — BSC3.01’s initial-evaluation text gives examples: "an appropriate provider (e.g., pediatrician, pediatric neurologist, developmental pediatrician, psychologist)." No closed list. LCSW: not named in BSC3.01's examples. California's LCSW scope statute, B&P § 4996.9, defines clinical social work to include "counseling and using applied psychotherapy of a nonmedical nature" and does not mention diagnosis (read in FindLaw's unofficial copy, current as of January 1, 2026; the official leginfo page blocks automated reads). It neither expressly grants nor bars an LCSW autism diagnosis, so ask the plan before relying on an LCSW-only diagnosis.[2][21]
No instrument is required for the diagnosis, which rests on "clinical observations or validated assessment tools." For the ABA assessment BSC3.01 expects standardized tools — "ABAS, Bayley or Vineland" for adaptive baseline, "QABF, FAST, FACT" for function — and the request form asks for the instruments (e.g. "Vineland, BRIEF, SSIS, SR-2, ADOS-2, TOPL-2, ABAS-3").[2][3]
No PCP referral and no separate order form. The HMO manual says "Blue Shield members may refer to behavioral health services by calling the Customer Service number on the back of their ID card," and ABA is authorized by Blue Shield, not the IPA or medical group. Blue Shield's commercial ABA prior-authorization form (rev. 07/26) is completed by the requesting qualified autism service provider. It asks for no physician prescription or referral, and an "MD signature [is] REQUIRED for urgent requests only." The order that does exist is the statute's. BSC3.01 quotes H&S § 1374.73: the treatment must be "prescribed by a physician and surgeon" or "developed by a psychologist," and provided "under a treatment plan prescribed by a qualified autism service provider." The policy's own note that "A board-certified behavioral analyst (BCBA) could prescribe ABA treatment" sits oddly with that statute, so collect the physician or psychologist prescription anyway. In practice the diagnosis comes first. BSC3.01 describes an initial diagnosis "obtained from an appropriate provider (e.g., pediatrician, pediatric neurologist, developmental pediatrician, psychologist)," followed by a functional behavioral assessment. Blue Shield publishes no validity period for a prescription and no prescription template.[7][2][3]
Published: "Blue Shield has a five business day turnaround time on all standard prior authorization requests" (ABA form); the July 2026 manual adds "Urgent: Within 72 hours" — urgent requests need an MD signature and "Scheduling issues do not meet the definition of an urgent request." That matches H&S § 1367.01(h). Self-funded groups sit under ERISA (29 CFR 2560.503-1: 15 days pre-service, one 15-day extension, 72 hours urgent) as the outer limit. Reauthorization: continued care needs an assessment or reassessment within the prior 12 months; the statute requires plan review at least every six months.[3][6][10][23]
Blue Shield’s manual: the employee plan pays before the dependent plan; for children of married parents "the group health plan of the parent, whose date of birth (month and day) occurs earlier in the year is primary"; a court decree controls where it applies, otherwise custodial parent, then the custodial parent’s spouse, then the non-custodial parent (joint custody with no decree uses the birthday rule). "Medi-Cal is considered a payor of last resort." With TRICARE or CHAMPVA, "Blue Shield is always the primary payor for covered services" — and those programs will not pay for services denied for breaking Blue Shield’s rules ("non-authorized, out-of-network"), so get Blue Shield’s authorization first.[6][24]
Telehealth is a place-of-service choice on the ABA request form (alongside office, home and community), so it is authorized code by code; Blue Shield’s general claim rule is "For Telehealth HIPAA compliant video services, use Modifier 95 in 24d and place of service 02 in 24b." H&S § 1374.14 requires telehealth coverage and payment on the same basis as in person. No ABA-specific list of telehealth-eligible codes is published.[3][6][22]
Ask the plan: The Blue Shield authorization — confirm which codes (e.g. 97155/97156) are approved for telehealth.
Coverage decides whether Blue Shield of 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.
A ceiling, not a floor: "Hours for supervision should either be no more than 2 hours of supervision for every ten (10) hours of direct service or have information to support why a higher ratio is medically necessary" (BSC3.01). Staff qualifications follow the QAS definitions, and Blue Shield "expects all network providers to comply with the changes made via SB 805."[2][6]
The ABA request form offers Office, Home, Telehealth, Community setting and Other; BSC3.01 describes ABA across "clinics, schools, homes, and communities," says home-based services "must be obtained from participating providers," and covers BHT "in the outpatient setting only." School-based ABA is not expressly excluded; the treatment plan may not be used for "Educational services."[3][2]
The ABA form collects a requesting QAS provider and a separate "Servicing/rendering QAS provider" (name, group, TIN, NPI); the manual requires the rendering provider’s NPI in blocks 24J and 33 and taxonomy in 24I, or claims "may not be accepted." Whether a technician is listed as rendering or billed under the supervising QAS provider is not stated for ABA.[3][6]
Ask the plan: Your Blue Shield provider agreement and the Blue Shield BH network/credentialing team — whether technicians are enrolled or billed under the supervisor.
Not addressed — BSC3.01, the ABA form and both 2026 manuals publish no 97153/97155 same-clock-time rule; BSC3.01 only reproduces the 97155 descriptor ("may include simultaneous direction of technician").[2]
Ask the plan: Blue Shield Provider Customer Service (800) 541-6652, or claims payment policies on Provider Connection (login).
No per-day unit cap or MUE table for ABA is published. Hours are authorized by CPT code per treatment plan; BSC3.01 says intensity rests on medical necessity "independent of the patient’s schedule," and school/IEP hours are not counted against treatment hours.[2]
Ask the plan: The authorization letter (hours per code); claim edits are behind the Provider Connection login.
No rule on who signs ABA session notes or when. BSC3.01 requires records that track "the intensity of services as well as the locations where those services are provided," with treatment changes documented "in consultation with the BACB supervisor."[2]
Ask the plan: Blue Shield provider agreement / medical-record standards on Provider Connection.
Yes — for ASD or PDD under medical policy BSC3.01 and California’s autism mandate, with prior authorization for both the assessment and treatment on DMHC-regulated plans.
No. Since January 1, 2026, Blue Shield manages ABA itself for commercial HMO, PPO, self-funded and Shared Advantage plans. Use AuthAccel, fax (844) 742-1155 (urgent (844) 729-1416), or Blue Shield Behavioral Health at (877) 263-9952.
Five business days for standard requests and 72 hours for urgent ones, per Blue Shield’s ABA form and 2026 manual — the H&S § 1367.01 floor.
Fully insured plans must cover behavioral health treatment, including ABA, for autism with no age or dollar caps, a treatment plan reviewed at least every six months, and — from 2026 — no forced rediagnosis to keep coverage. Self-funded ERISA and Medi-Cal plans are exempt.
Twelve months from the date of service unless your contract says otherwise, per Blue Shield’s July 2026 provider manual. Provider disputes are due within 365 days of Blue Shield’s action (or longer if your agreement allows) and are resolved within 45 working days.
