ABA Insurance Changes in 2027: What Providers Need to Prepare
Before 2027 begins, ABA providers need to review more than insurance benefits.
Six new CPT codes take effect January 1, 2027. Medicaid policies are also changing in several states, while insurance renewals and new eligibility requirements may affect patient coverage.
Your financial results will depend on your payer contracts, authorizations, documentation, and billing setup are prepared for these changes. Here’s what ABA providers should review before submitting their first claims of 2027.
What Changes With ABA CPT Codes in 2027
The 2027 ABA CPT code set includes six new codes and updates to existing codes. Billing teams need to understand these changes to submit claims correctly. Read our 2027 ABA CPT code changes guide guide to learn about the new, revised, and deleted codes.
Code | 2027 purpose |
97180 | Qualifying non-face-to-face clinical services personally performed by a physician or other qualified healthcare professional (QHP), in 15-minute units. |
97173 | Face-to-face treatment with analysis by a physician or other QHP. |
Revised 97155 | Patient-facing technician direction and analysis by a physician or other QHP. |
97148 and +97149 | Harmful behavior assessment involving two technicians, with an add-on code for additional technician time. |
97159 and +97160 | Harmful behavior treatment involving two technicians, with an add-on code for additional technician time. |
These services must meet their full coding requirements. Revised 97155 does not cover general staff or certification supervision.
Codes 0362T and 0373T will no longer be included in the 2027 set. These codes covered specialized destructive behavior services and were not meant for general indirect BCBA work.
For ABA billing teams, choosing the right code is only the first step. Confirm coverage, rates, provider qualifications, modifiers, authorization units, and concurrent billing rules with each payer.
Will 97180 Increase Practice Revenue
Code 97180 offers a way to report qualifying indirect clinical work. This creates a potential revenue opportunity, but actual payment still depends on the payer.
Category I status does not guarantee reimbursement or confirm coverage under a specific plan. Before including this code in revenue projections, get written payer instructions to understand how it will be handled.
Existing contracts may already outline how new codes are adopted and priced. Review these terms before assuming that every rate will require a new negotiation.
Code selection also depends on the date of service. A valid 2026 service remains a 2026 service, even if you submit the claim in January 2027.
What Is Changing With ABA Prior Authorization in 2027
Under CMS-0057-F, certain affected payers generally began following seven-calendar-day standard decision deadlines and 72-hour expedited deadlines in 2026. Federally facilitated Marketplace plan issuers are excluded from those decision-time requirements.
Electronic prior authorization API requirements generally begin in 2027, with timing varying by payer type. These requirements do not apply to every commercial employer plan.
Ask your software vendor which payer connections it supports. A payer’s deadline does not guarantee that your EHR will connect automatically.
For existing approvals, confirm how codes and units will convert. A correct claim can still be denied if it does not match the authorization.
What Should ABA Practices Check Before Insurance Plans Renew in 2027
Keeping the same insurance company does not mean a patient’s benefits stay the same. Plans, provider networks, deductibles, and authorizations can change at renewal.
Before January sessions, confirm active coverage, ABA benefits, network participation, approved services, and the family’s expected costs.
Adult Medicaid: New eligibility requirements generally begin January 1, 2027, for certain adults ages 19–64. Exemptions apply, so check the patient’s eligibility group and state rules.
Marketplace plans: KFF reported a 15% median proposed premium increase for 2027. Actual costs vary, and premiums do not determine ABA deductibles or copayments.
Connecticut: The cited report places coverage expansion for individuals under age 26 at January 1, 2027. Confirm policy terms; self-funded employer plans follow different rules.
Finding a coverage change before treatment gives your team time to resolve it before claims become unpaid balances.
Which State Medicaid ABA Changes Should Providers Watch in 2027
The ABA CPT code update does not cause Medicaid rate cuts. These are separate policy decisions and should be budgeted separately.
Indiana: A 6% reduction to nongroup ABA maximum fees took effect April 1, 2026. Another 4% reduction for individual and group ABA services is scheduled for April 1, 2027. The published 97153 rate drops from $16.04 to $15.39 per 15-minute unit, or $61.56 per hour before operating costs.
Indiana also introduced a 4,000-hour comprehensive ABA allocation, with a review pathway for additional medically necessary care under EPSDT. Targeted ABA is available up to 15 hours weekly. Coverage for patients ages 21 and older ended after the September 30, 2026 transition. Updated guidance is needed for replacement-code billing.
New York: Fee-for-service reimbursement for technician-delivered 97153 falls to $9.63 per unit, or $38.52 per hour, effective October 1, 2026. This is a 2026 change. Check managed care contract rates separately.
Virginia: The July 2026 notice describes a 20-hour weekly limit with EPSDT exceptions and an autism diagnosis requirement, including provisional diagnoses for children ages 5 and younger. That notice makes implementation dependent on CMS approval and later guidance. Check for a subsequent implementation notice before applying the changes.
North Carolina and South Carolina: Both issued 2026 updates affecting service delivery or provider requirements. These notices do not mean Medicaid rates will be cut across the board in 2027.
Review your actual payer rates against staffing costs, approved hours, and expected collections. A national headline cannot tell you what your practice will earn.
Do Medicaid Service Limits Affect a Child’s ABA Coverage
Reaching an hour limit does not automatically mean medically necessary ABA must stop.
Early and Periodic Screening, Diagnostic, and Treatment (EPSDT) protections apply to eligible Medicaid patients under 21. The May 2026 CMS guide restates existing protections rather than creating a new benefit.
When requesting additional ABA hours, explain the child’s needs, treatment goals, and risks of reducing care. Maintaining skills or preventing a decline can support medical necessity, even when new progress is limited.
The CMS ABA toolkit discusses confirmed autism diagnoses in relation to sustained ABA coverage. It does not create a nationwide ban on non-autism care.
Check the applicable state and payer rules. If a request is denied, include supporting clinical records and meet the appeal deadline.
What Flags Should Providers Watch for in the First 2027 Claims
Confirm payer policies: Obtain coverage instructions, fee schedules, and effective dates for the six new codes.
Review authorizations: Check code conversion, approved units, provider qualifications, and renewal requirements.
Update billing systems: Align code tables and documentation templates with the date of service.
Recheck benefits: Verify eligibility, networks, deductibles, and patient responsibility.
Review revenue exposure: Budget with contracted rates and track denials, appeal deadlines, and unpaid balances.
Assign an owner to each check. Unanswered payer questions should have a follow-up date before services begin.
