Missouri manual section 6.1
Applied behavior analysis
Official service name: Applied Behavior Analysis
Applied Behavior Analysis (ABA) is a short-term service that uses assessment, a written Behavior Support Plan, direct treatment, caregiver or staff training, and repeated data review to help a person build functional behavior, communication, and social skills or reduce behavior that threatens health, safety, community living, or placement stability.
What the manual describes
What this service can help with
- Learning functional or equivalent replacement behaviors connected to an existing challenging behavior
- Improving communication, social functioning, daily skills, and tolerance for ordinary changes
- Reducing behavior that may contribute to hospitalization or placement outside the home
- Developing and testing a Behavior Support Plan using direct observation and measurable data
- Training family members, caregivers, or staff who are necessary to carry out or monitor the plan
Source-backed working pathway
To establish you'll probably need:
These steps translate the cited manual section into a practical review sequence. Confirm the current local process before acting.
Describe the functional need with the support coordinator and planning team.
Identify the behavior, communication, social, or functional-skill concern in observable terms; where and when it happens; how it affects health, safety, home or community life; and what improvement would matter to the person.
Confirm whether the state plan or the waiver is the correct funding route.
Review the person's age, autism diagnosis status, and Medicaid state-plan or Healthy Children and Youth coverage before requesting waiver ABA. The manual requires available state-plan services to be used before overlapping waiver services.
Arrange the qualified assessment needed to define the service.
A qualified professional should determine which assessment component is appropriate, identify relationships between behavior and the environment, and produce recommendations for the Behavior Support Plan. Exposure-based assessment requires the manual's additional safety conditions and prior approval.
Put the measurable ABA goals and support arrangement in the plan.
The person-centered service plan and Behavior Support Plan should identify observable targets, separate measurable goals, who will collect data, who needs training, how fidelity and progress will be monitored, and which assessment or treatment components are authorized.
Confirm the provider, authorization, start procedure, and review schedule.
Verify the provider's Department of Mental Health contract and the qualifications and supervision of each professional or technician. Confirm the authorized component and units, referral and start steps, locations or approved virtual delivery, caregiver participation, data reporting, and how progress or discharge will be reviewed.
Important boundaries
Limits that may affect fit or authorization
- ABA is available through all four Missouri DD waivers, but the correct funding route depends on the person's age, diagnosis, and available Medicaid state-plan coverage.
- The manual says the Medicaid state plan covers ABA for children under age 21 with an autism spectrum disorder diagnosis. Waiver ABA is limited to additional services not otherwise covered by the state plan, including Healthy Children and Youth services.
- The manual describes waiver ABA as short term. The goal includes helping ordinary caregivers and support staff use sustainable strategies as the specialized service succeeds.
- Different assessment and treatment components require different qualified professionals, supervision arrangements, and authorization. Some exposure-based components require advance approval from the Division of Developmental Disabilities Chief Behavior Analyst.
- A Behavior Support Plan requires observable targets, direct data collection, fidelity monitoring, graphic presentation of progress, and measurable goals in the person-centered service plan.
- The manual lists different unit limits for each ABA component. Current authorization and billing limits must be confirmed for the specific service rather than inferred from the general ABA label.
- Comprehensive and Community Support waivers remain under a temporary renewal extension through December 27, 2026, or until CMS grants final approval. Confirm the currently approved rules with the support coordinator; proposed renewal changes are not automatically active.
