L.A. Care Requires a Parent at Every ABA Session. DHCS Says Plans Can't.

L.A. Care's Medical Necessity Guidelines, Behavioral Health Treatment (BHT) / Applied Behavior Analysis (ABA), last updated March 26, 2026 and applying to its Medi-Cal plan only, lists what a treatment plan must document. Item 1.2.2.8.2 reads: “Parent/guardian/caregiver must be present and available during the totality of the therapy sessions and documented.”

DHCS's All Plan Letter 23-010 (Revised), which governs BHT across Medi-Cal managed care, says in footnote 13 that plans “must accommodate legal requirements regarding parental participation that apply generally to providers of BHT services, but they cannot require participation by parents/guardians.”

The turn: two documents, one provider

The two can be read together only narrowly. “Present and available” isn't the same as participating in treatment, and a plan may argue it's a supervision and safety requirement rather than a participation one. But a provider whose session happens while a parent is at work is the one who carries the gap, whichever reading prevails. This article doesn't decide which reading is correct. It sets the two texts side by side.

The APL also says: “Blanket limitations or restrictions on benefits and services, such as caps on number of hours, are prohibited.”

What else L.A. Care requires

• At least two direct observations in the member's home or natural community settings during assessment.
• At least one standardized tool from each category: skills (such as VB-MAPP, ABLLS-R, AFLS or PEAK), adaptive (Vineland-3 or ABAS-3), and an FBA where there are problem behaviors.
• Supervisors review data “no less than weekly.”
• Progress reports include the “rate and percentage of mastered programs” and change scores.
• Discharge where there's “a consistent lack of change” in data “for at least six months despite documented treatment modifications.”

The limits

We haven't seen a denial citing 1.2.2.8.2, and L.A. Care hasn't said how it applies the rule to school or clinic sessions. APL 23-010 dates from November 2023. We found no finalized 2026 replacement.

What you must know or do

• Clinical directors: for L.A. Care Medi-Cal clients, document in each session note whether a caregiver was present and available. That's what 1.2.2.8.2 asks to see.
• Intake: flag families who can't be present for sessions before authorization, not after a denial.
• Billers: if a denial or reduction cites caregiver presence, quote APL 23-010 footnote 13 in the appeal, and keep a copy of both documents in the file.
• Check your assessment packets for two home or community observations and an adaptive measure. Missing either is a separate reason for denial.
