UnitedHealthcare Prior Authorization Changes for ABA Therapy Under 18: December 2026 Update
If your ABA practice bills UnitedHealthcare commercial plans, a significant prior authorization change is coming. Starting December 1, 2026, UHC will remove prior authorization requirements for CPT codes 97151–97158, 0362T and 0373T for eligible members under 18.
This includes ABA assessments, individual treatment, group sessions, protocol modification, and family guidance. The change could reduce authorization requests and paperwork for billing teams.
However, the exemption does not apply to every UnitedHealthcare plan. The published commercial code list includes these ABA services, but the Community Plan and Individual Exchange lists do not. Billing teams should verify the patient's plan and CPT code before changing their authorization process.
No prior authorization does not mean automatic claim payment. Eligibility, provider enrollment, medical necessity, treatment units, and clinical documentation still matter.
What changed in UnitedHealthcare's prior authorization policy
On November 2, 2026, UnitedHealthcare announced that it would remove prior authorization requirements for more than 2,000 pediatric procedure codes, effective December 1, 2026.
The changes cover services across several pediatric specialties, including certain assessments, diagnostic tests, procedures, and therapies. UHC estimates that the update will eliminate nearly two-thirds of its pediatric prior authorization volume.
ABA therapy codes appear on the published commercial-plan reduction list.
For practices that have spent weeks waiting for approval before starting treatment, the change could make intake easier. Once a qualifying patient's assessment and treatment planning are complete, the practice may no longer need to wait for a separate authorization decision for the exempt service.
That doesn't remove the need to check insurance benefits or establish medical necessity. The patient must still qualify for the service under their plan.
UnitedHealthcare's official November 2 announcement explains the broader pediatric policy.
What happens to existing ABA reauthorizations
ABA practices often track authorization periods and request renewals when approved units or authorization dates are approaching their limits.
For services covered by the new exemption, those repeat authorization requests may no longer be needed for qualifying dates of service beginning December 1.
Consider a practice treating 30 children with UnitedHealthcare coverage. If 12 have eligible commercial plans and the remaining children have Community Plan or other coverage, the practice shouldn't remove authorization reminders for all 30.
It should first confirm which patients qualify, then update only those authorization records.
Existing approvals, sessions before December 1, and services outside the exemption still need to follow the applicable plan requirements.
Which ABA CPT codes no longer require prior authorization for members under 18
UnitedHealthcare's commercial-plan document PCA-1-26-01927-Clinical-QRG lists ten ABA-related codes included in the December 1, 2026 authorization reduction.
CPT code | ABA service |
97151 | Behavior identification assessment |
97152 | Behavior identification supporting assessment |
97153 | Adaptive behavior treatment by protocol |
97154 | Group adaptive behavior treatment by protocol |
97155 | Adaptive behavior treatment with protocol modification |
97156 | Family adaptive behavior treatment guidance |
97157 | Multiple-family group adaptive behavior treatment guidance |
97158 | Group adaptive behavior treatment with protocol modification |
0362T | Behavior identification supporting assessment |
0373T | Adaptive behavior treatment with protocol modification |
There are no ABA codes left out. Assessment, treatment, supervision, family training, and group services are all covered. If your practice bills any of these codes for UHC commercial members under 18, the PA step is gone.
One timing note worth flagging: 0362T and 0373T are being deleted from the CPT code set on January 1, 2027, just 31 days after this PA removal takes effect. Six new ABA codes replace them. Your billing system needs to handle both the PA removal on December 1 and the 2027 ABA CPT code transition on January 1 as two separate updates in the same window.
What ABA providers need to know about plan exceptions
UnitedHealthcare's broader pediatric authorization reduction program includes commercial plans, Individual Exchange plans, and select Community Plans.
However, the CPT codes being removed differ between those products.
Does the change apply to UHC Medicaid or Community Plan
The ten ABA-related codes are confirmed on the published commercial-plan reduction list. They aren't listed in the corresponding published Individual Exchange and Community Plan reduction documents. That means an ABA provider should not automatically stop requesting authorization for patients covered through UHC Community Plan.
Medicaid managed care requirements can differ by state. Some Community Plans participate in the broader pediatric reduction initiative, but that doesn't establish that ABA services are exempt in those plans.
For ABA practices, understanding these differences can make a real difference when working with UnitedHealthcare.
For example, two patients may both need CPT 97153. One has employer-sponsored UHC commercial insurance, while the other has UHC Community Plan coverage.
The commercial member's service may qualify for the December exemption. The Community Plan member's authorization requirements need to be checked separately.
UnitedHealthcare also excludes certain products from the broader initiative, including Medicare Advantage, Dual Eligible Special Needs Plans, Health Plan of Nevada Medicaid, and specified UMR arrangements.
Does no prior authorization mean no more claim denials
No. Removing prior authorization eliminates only one possible reason for denial. UnitedHealthcare can still review claims, request clinical records, or deny services that lack proper documentation. Claims may also be denied due to inactive coverage, incorrect provider enrollment, or unsupported treatment units.
For example, an ABA practice provides four hours of CPT 97153 to a 12-year-old with eligible commercial coverage on December 8. Even without an authorization requirement, the claim must include accurate provider details, service dates, units, and supporting documentation.
When a claim is denied for missing authorization, verify the plan-specific exemption before requesting reconsideration. The published policy supports the review but does not guarantee approval.
What should ABA providers verify before billing UnitedHealthcare
Removing PA doesn't remove every other billing requirement. Here's what to confirm before changing your workflow.
Start with the UnitedHealthcare Provider Portal. Use the Prior Authorization and Notification tool to check the member's plan and intended CPT code.
Before December 1, practices should review:
Plan type and eligibility. Separate commercial patients from Community Plan, Individual Exchange, and other UHC products. Confirm active coverage and the ABA benefit.
Authorization requirements. Check each CPT code and date of service. Save the portal result or payer reference number.
Existing authorizations. Review patients whose approvals extend beyond December 1. Keep authorization tracking active wherever the exemption isn't confirmed.
Provider and billing information. Confirm the rendering provider's enrollment, group affiliation, and billing details.
Treatment records. Continue documenting medical necessity, treatment goals, session time, and the units billed.
If your practice works with outside prior authorization services, share the commercial code list and the plan exceptions with that team.
What If UnitedHealthcare Denies a Claim for Missing Authorization
Suppose CPT 97155 is billed for an eligible commercial member under 18 on December 8, but UHC denies it for missing authorization.
Before resubmitting, verify the patient's plan, service date, and CPT code. Check your original portal confirmation and contact UHC. If the exemption applies, request reconsideration using document PCA-1-26-01927-Clinical-QRG and the December 1 effective date.
What Should ABA Practices Do Before December 1
Review your UHC caseload and identify patients who qualify for the exemption. Update authorization trackers and let intake, scheduling, and billing staff know which patients still need approval.
Keep the January 1, 2027 ABA CPT code changes separate. They involve different billing requirements.
For eligible commercial members, the change can reduce authorization paperwork and treatment delays. Provider enrollment, coverage verification, and clinical documentation still need attention.
