Colorado Lists 10 Interventions That Need Extra Justification in ABA Treatment Plans

Health First Colorado's September 2026 provider bulletin (B2600542) includes an education update for Pediatric Behavioral Therapy, the state's ABA benefit. Acentra Health, which reviews prior authorization requests, has identified “recurring documentation issues” that lead to “additional review, pends or denials.” The bulletin names ten kinds of intervention that draw that scrutiny “when submitted as primary treatment interventions”:

1. unspecified coping, calming, self-management, breathing and de-escalation strategies;
2. self-regulation programs, Zones of Regulation, behavior relaxation training and cool-down spaces;
3. CBT and ACT interventions;
4. social stories and narratives;
5. mindfulness, yoga and similar relaxation-based interventions;
6. muscle relaxation techniques;
7. sensory diets, sensory integration, weighted blankets and vests;
8. perspective taking, social inferencing, and interventions focused on “emotions, feelings or other mentalistic/private events”;
9. journaling and positive self-talk;
10. behavioral mapping and similar programs.

The turn: not a ban, a burden of proof

The bulletin says these are “not automatically prohibited or non-covered.” But “naming an intervention or curriculum alone is not sufficient.” For each one, the plan must:

• identify the observable, measurable behavior or skill it targets;
• explain how the assessment supports it;
• describe how it's delivered within the provider's scope;
• specify how progress is measured.

Some items will split the field. ACT has its own behavior-analytic research literature, and many clinicians treat self-management and relaxation training as behavioral procedures. The bulletin doesn't settle that. It says what a reviewer needs to see.

Enhanced staffing ratios, co-treatment and group services also need documentation that “clearly supports the clinical rationale.” Acentra encourages submitting PARs 14–21 days before the start date.

The limits

This is a reminder under current criteria, not a new rule, and it has no effective date. It gives no denial rates. The phrase “when submitted as primary treatment interventions” suggests a supporting role draws less attention, but the bulletin doesn't say so.

What you must know or do

• BCBAs: search every Colorado treatment plan due for reauthorization in the next 60 days for the ten categories. For each hit, check the four elements above are written out, not implied.
• Where a listed intervention is supporting, not primary, say so in the plan.
• Intake and authorizations: move PAR submission to 14–21 days before the start date.
• If a request pends or denies, email coproviderissue@acentra.com, and escalate to hcpf_um@state.co.us if it isn't resolved.
