Your child has been receiving ABA. You've settled into a routine. The therapists know your child. You finally feel like you know what to expect. Then you hear:
It's understandable for that news to feel alarming! But before assuming that therapy is simply ending, figure out what actually happened. A recommendation from your child's clinician, a request submitted to an insurer, an authorization decision, and the number of hours a provider can staff are four different things. Understanding which one changed is the first step to addressing the problem.
Those scenarios can sound identical when someone says, “Your hours are being reduced,” but they aren’t! Knowing the specifics will help you advocate better.
Look for: What was requested? What was approved? What was denied and why? What criteria were used? When does the decision take effect? How can the decision be appealed? Is there a deadline? Save that document.
Sometimes the disagreement isn't about whether a child has autism. It's about whether the documentation supports the specific treatment being requested now.
Keep these items together:
- Current treatment plan
- Most recent assessment
- Current authorization
- Authorization or denial notice(s)
- Relevant progress reports
- Insurance correspondence
- Appeal paperwork
- Notes from any/all calls (include date, representative name, and reference number)
ABA policy isn't static. States can (and often do!) change Medicaid coverage rules, eligibility pathways, prior-authorization procedures, provider requirements, and other program details.
Here are some helpful resources worth bookmarking.
CMS Medicaid Autism Services
CMS's central resource explains federal Medicaid coverage pathways for autism services and links to additional guidance. (Medicaid)Medicaid State Plan Amendments
Want to know whether your state's Medicaid program is changing? CMS maintains a searchable database of State Plan Amendments. These can include changes involving coverage, reimbursement, eligibility, prior authorization, and other Medicaid policies. (Medicaid)Michigan's 2026 ABA Amendment
For Michigan families, CMS's page for MI-25-0020 includes the approval information and underlying plan amendment. (Medicaid)HHS-OIG ABA Audit Series
For families and providers following broader Medicaid ABA policy, OIG's national audit initiative is also worth watching. Its completed audits have repeatedly focused on areas such as documentation, billing, provider credentials, and prior authorization. (HHS Inspector General)
