New Hampshire Denies ABA Group Claims Without an Enrolled BCBA. It Started August 1.
A program integrity review found groups leaving rendering providers off claims. Since August 1, a group ABA claim without an enrolled rendering BCBA is denied.
New Hampshire Medicaid began denying ABA group claims on August 1, 2026 if the claim doesn't name an enrolled rendering provider. That deadline passed eight weeks ago. A group that hasn't changed how it bills has had eight weeks of claims exposed to denial.
Why the state did it
The Division of Medicaid Services announced the rule in an April 29 notice. It said the Bureau of Program Integrity had reviewed ABA claims and found that "many Medicaid-enrolled groups do not consistently include rendering providers on claims." It also found that those providers "may not be actively enrolled in New Hampshire Medicaid or credentialed with individual Managed Care plans."
The rule reaches past billing. A BCBA who works for a group has to be enrolled with the state personally, not just through the group.
What the notice requires
- Every BCBA enrolls. "BCBAs are required to enroll in New Hampshire Medicaid and be listed on claims as rendering providers," with an active NPI obtained before enrollment.
- The rendering NPI goes on the claim: box 24-J on the CMS-1500, or box 76 on the UB-04.
- Technicians don't enroll, but their supervisor goes on the claim. The supervising BCBA "must be listed as the rendering provider on all claims for services delivered under their supervision."
- Then credential with each plan. After state enrollment, rendering providers "should also credential with any individual Managed Care plan for which they provide services."
- The consequence: "Beginning August 1, 2026, claims submitted by an ABA Group without an enrolled rendering provider on the claim will be denied."
The limits
The notice doesn't say how each managed care plan applies the denial. For that it directs providers to their MCO provider representative. It also doesn't say whether denied claims can be corrected and resubmitted, or what timely filing limit applies if they can. It sets no rate, cap or penalty beyond the denial itself.
What you must know or do
- Billing staff: pull every New Hampshire ABA claim denied since August 1 and sort out the ones denied for a missing or unenrolled rendering provider. Those are the claims to fix first.
- Owners: list every BCBA who supervises New Hampshire Medicaid clients. Check three things for each one: an active NPI, individual state enrollment, and credentialing with each MCO the client belongs to. Anyone missing one of the three can't be the rendering provider on a clean claim.
- For technician sessions: check that the claim names the supervising BCBA, not the group NPI alone.
- Before resubmitting: ask each MCO's provider representative, in writing, whether corrected claims for dates after August 1 will be accepted and within what window.
