CalOptima Health is the County Organized Health System for Orange County — the only Medi-Cal plan there, with 772,737 members in August 2026. "CalOptima Health administers BHT services, including ABA, for Medi-Cal members" through its Behavioral Health Integration department; BHT is the one EPSDT service that does not go to the member’s health network. Its policy GG.1548 (revised May 1, 2026) is unusually precise about what counts as a valid recommendation, so most avoidable denials here are paperwork denials.
GG.1548 spells it out. The recommendation must carry the full name and credentials of a licensed physician, surgeon or licensed clinical psychologist — it "cannot be an educational psychologist or master’s level clinician/practitioner (LMFT, LCSW, LPCC, PA, NP, etc.)," though an NP or PA recommendation works with an MD signature. The recommendation and diagnosis must come "from the same physician/surgeon/clinical psychologist and all within the same document," on letterhead, a prescription pad, a psych testing report or an EHR record, with a date, a second member identifier and a signature (wet, electronic, digital or scanned). Wording matters: "Applied Behavior Analysis (ABA), Behavioral Health Treatment (BHT), ABA therapy, ABA treatment, ABA or BHT, Behavior or Behavioral Therapy and Behavioral Analysis" are accepted, and "ABA evaluation wording is acceptable only for FBA request."[1][2][3][4]
Then: request the FBA on the BHT-ARF (H0031) or the provider portal; the treatment plan must use CalOptima’s template ("All fields and items on the template cannot be altered or removed"), include the Vineland-3 ("The Vineland-3 Adaptive Behavior Scale is required"), meet the APL 23-010 elements and be signed by a BCBA or licensed practitioner. Units run "typically 6 months," and continued-treatment requests go in no more than 30 calendar days before the last covered date. Providers must be CalOptima-contracted and — per the 2026 policy — enrolled in Medi-Cal through PAVE; the 2023 FAQ’s statement that ABA groups have "no pathway for Medi-Cal enrollment" is superseded.[1][2][3][4]
The questions that decide whether a family can start with CalOptima Health (Medi-Cal), and what they have to bring. Each maps onto something intake should ask on the first call.
Under 21 (GG.1548). No minimum age.[1]
A licensed physician, surgeon or licensed clinical psychologist. Explicitly excluded: educational psychologists and master’s-level clinicians (LMFT, LCSW, LPCC); PAs and NPs only with an MD co-signature.[1]
"The Vineland-3 Adaptive Behavior Scale is required" for treatment plans, with ABAS, DAYC, VB-MAPP and ABLLS as optional supplements; adaptive testing is needed for new plans "and for every reporting period." No instrument is mandated for the diagnosis itself.[1][3]
The family calls CalOptima Health Behavioral Health (855-877-3885, 24/7), and a contracted provider "will obtain all medical necessity information from the member and submit a request"; PCPs direct members to the same line. BHT does not go through the member’s health network — the manual routes every other EPSDT service there "except for BHT." To switch providers, the member calls the BH line and the new provider submits a new authorization.[4][3]
Routine: "Seven calendar days from receipt of the information reasonably necessary to render a decision … but no longer than 14 calendar days from the receipt of the request," extendable by 14 days; expedited "no later than 72 hours"; "Any decision delayed beyond the time limits is considered a denial." On the provider side, the FBA must be offered within 10 business days of the FBA authorization start (tracked on the BHT Access to Care Form). Reauthorization: the plan is reviewed at least every six months, and continued-treatment requests go in no more than 30 days before the authorization ends.[4][5][1]
"State law requires CalOptima Health to be the payer of last resort when Other Health Coverage (OHC) is identified." Bill the other coverage first; "CalOptima Health’s reimbursement is the difference between the CalOptima Health allowable amount and the OHC carrier payment," and CalOptima is "not liable for OHC-covered services if the recipient elects to seek treatment from a provider not authorized by the OHC." It does not say whether a BHT-ARF is still needed when the other plan is primary — ask.[4]
The recommendation must be dated, but GG.1548 sets no maximum age for it, and APL 23-010 sets none either.[1][6]
Ask the plan: CalOptima Health Behavioral Health (855-877-3885) — whether an older recommendation will be accepted.
No BHT-specific rule. CalOptima’s general Medi-Cal telehealth rules: documented consent before first use, services must meet the code’s definition, audio-only and video must be offered, the in-person option preserved, and providers enrolled in Medi-Cal — the state rule, which does not settle technician-delivered direct service by video.[4][8]
Ask the plan: CalOptima Health Behavioral Health (855-877-3885) — which BHT codes it will authorize by telehealth.
Coverage decides whether CalOptima Health (Medi-Cal) 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.
CalOptima’s 2023 FAQ (not restated in the 2026 policy): supervision is authorized "at a rate that falls between 10–20% of weekly direct paraprofessional services hours"; up to 90% of supervision by a BMA is accepted "if oversight is documented"; at most 20% of supervision hours per six months (minimum 3, maximum 8 hours) may be indirect.[3]
No daily or weekly caps are published, and "Decreasing the amount and duration of services is prohibited if the therapies are Medically Necessary."[1]
"Home or community-based setting, including clinics," and school when clinically indicated, with hours proportionate per setting; CalOptima is primary for BHT "on-site at school or during remote school sessions."[1]
QAS provider organizations, individuals and CBOs "must apply for enrollment in the Medi-Cal program through … PAVE" (GG.1548, 2026), and must be CalOptima-contracted and credentialed (every three years), with a roster of all providers and paraprofessionals. The BHT-ARF captures NPI, TIN and Medi-Cal ID; its codes are H0031, H0032-HN (non-BCBA), H0032-HO (BCBA), H2014, H2019, S5108 and S5110.[1][2]
Partly addressed: "Can H0032 HO and H0032 HN be billed at the same time for the same member? No, CalOptima Health does not allow for providing the same services by multiple providers for the same member on the same day." No rule is published on supervision (H0032) overlapping direct service (H2019).[3]
Ask the plan: CalOptima Health Behavioral Health (855-877-3885) or Provider Relations (714-246-8600) — whether H0032 and H2019 may be billed for the same minutes.
Treatment plans need a BCBA or licensed practitioner signature and date (wet, electronic, digital or scanned). Session documentation follows CalOptima’s medical-records policy GG.1603, which was not read.[1]

Yes — Behavioral Health Treatment for Medi-Cal members under 21 in Orange County, with or without an autism diagnosis, run by CalOptima’s own Behavioral Health department.
A licensed physician, surgeon or licensed clinical psychologist — in one dated, signed document that also carries the diagnosis. LMFTs, LCSWs, LPCCs and educational psychologists are not accepted, and NP/PA recommendations need an MD signature.
Seven calendar days for routine requests (no more than 14) and 72 hours for expedited ones; a missed deadline counts as a denial.
