2027 Is Coming: What ABA Providers Should Know After the Autism Law Summit

The 2026 Autism Law Summit wrapped up in Charleston this week, and there was a lot for ABA providers to pay attention to.

But one development deserves to be at the top of the list:

ABA CPT codes are changing January 1, 2027.

And this isn't something to leave for December.

The Big One: New ABA CPT Codes

The 2027 CPT update brings six new adaptive behavior service codes, revisions to existing codes 97151–97158, updated coding guidance, and the elimination of two Category III codes.

For ABA organizations, the bigger question isn't simply what are the new codes?

It's:

What is each payer going to do with them?

A new CPT code doesn't automatically mean a payer will cover or reimburse it. Commercial plans, Medicaid programs, and managed care organizations may have different implementation timelines, authorization requirements, policies, and fee schedules.

That's where things can get messy.

Before January, ABA organizations should be talking to their payers, reviewing contracts and authorizations, confirming their billing and EMR systems are ready, and training the teams who will actually use the new codes.

CPT Changes Weren't the Only Thing on the Agenda

The Summit also highlighted several issues that could have a real operational impact on ABA providers in 2027.

Network adequacy and access to care were front and center. With families still facing long waitlists in many markets, payer networks — and whether they actually provide meaningful access to ABA services — continue to matter.

ABA services inside schools also received attention, particularly around the responsibilities of private providers, schools, and insurers when treatment occurs during the school day.

For organizations expanding, facility licensure is another area worth watching. Requirements can vary significantly by state and can affect how quickly a new ABA center can actually open.

The Summit also tackled insurance denials and appeals, accreditation and accountability, residential services and the HCBS Settings Rule, and legal and workforce developments affecting autism service organizations.

In other words: 2027 is shaping up to bring more than a CPT update.

Don't Wait Until January

If you run an ABA organization, the next two months are a good time to get ahead of the transition.

Start asking:

• Are our payers ready for the 2027 codes?
• Will existing authorizations need to change?
• Are our EMR and billing systems ready?
• Are our payer contracts and fee schedules current?
• Are our provider rosters, locations, licenses, CAQH profiles, and enrollments accurate?
• Does our team know what changes January 1?

Because the worst time to discover a payer problem is after you've already provided the service.

At BYOND™ Credentialing Solutions, we help ABA organizations stay ahead of the payer-side work — credentialing, enrollment, contracting, provider additions, recredentialing, roster maintenance, demographic updates, and ongoing payer follow-up.

The codes may be changing.

Your credentialing shouldn't be the thing slowing you down.
