Amerigroup says every Georgia ABA provider was sent a rate reduction notice. Silence counts as acceptance, and written objections are due October 1, 2026.
Key Takeaways
- Amerigroup has told Georgia ABA providers that the rate reduction notice went to every provider organization in the state: Autism Providers of Georgia said any organization that has not received one should assume the notice went to the wrong address.
- Providers who do not object in writing are treated as having accepted the reduction: The notice sets a deadline of October 1, 2026 and requires objections to be sent by certified mail to Amerigroup Community Care, Health Care Networks, 740 W. Peachtree Street NW, Atlanta.
- The objection deadline and the payment deadline are not the same date: Autism Providers of Georgia has advised delivering objections by September 1, 2026 to avoid being paid at the reduced rate in the interim. That is also the date a separate set of Amerigroup prior authorization changes for ABA treatment and reassessments takes effect.
- No Georgia rule requires a managed care plan to pay the published ABA fee schedule: That gap let CareSource cut to 80 percent of a schedule that pays $15.58 per 15-minute unit for technician-delivered treatment in a clinic, and the Department of Community Health has since extended all three incumbent contracts through June 30, 2027 without publishing a member transition date.
Georgia ABA providers have until October 1, 2026 to object in writing to a reimbursement reduction from Amerigroup Community Care, and those who do nothing will be treated as having agreed to it.
Autism Providers of Georgia (APG), a provider advocacy organization, published the deadline on LinkedIn on August 19, saying Amerigroup leadership has stated that all ABA providers in Georgia were sent the rate reduction notice. Any provider organization that has not received one, APG said, should conclude that Amerigroup sent it to the wrong address. The post reproduced the objection provision from the notice, which directs providers to send written objections by certified mail to Amerigroup Community Care, Health Care Networks, 740 W. Peachtree Street NW, Atlanta, Georgia 30308.
That address matches the company’s Georgia footprint. Amerigroup operates in the state as AMGP Georgia Managed Care Company, Inc., an Elevance Health subsidiary whose principal place of business is listed at 740 W. Peachtree Street NW in federal court filings.
Acuity has not obtained the full notice. The size of the reduction, the procedure codes and provider types it reaches, and its stated effective date are not established by the excerpt APG published. No corresponding announcement appears on Amerigroup’s Georgia provider news site, where the company posted its two public autism services notices this year. Acuity has requested comment from Amerigroup and APG and will update this story as they respond.
What the Amerigroup Georgia Medicaid ABA Rate Reduction Notice Requires
The mechanism will be familiar to any Georgia provider who worked through the spring. It is the structure CareSource Georgia used in March, when it delivered a Notice of Material Amendment by certified mail reducing reimbursement to 80 percent of the Georgia Medicaid fee schedule, gave providers 45 calendar days to object, and treated silence as acceptance. That amendment, delivered March 27, left prior authorization requirements and billing guidelines untouched.
Two dates matter in the current notice, and they are not the same date. October 1, 2026 is the last day Amerigroup says it will accept a written objection. The reduction itself takes effect earlier, and APG has advised providers to have objections delivered by September 1, 2026 to avoid being paid at the lower rate in the meantime. A provider reading the notice for the deadline would see a window running into October. A provider reading it for the money would see one closing on September 1.
What an objection actually accomplishes is the unsettled question. As reproduced in APG’s post, the clause states that once Amerigroup receives written notice of an objection, “the change will take effect until both parties mutually agree on a resolution.” Read as written, that leaves the reduction in force while the dispute is open, which would make an objection a request to negotiate rather than a hold on the rate. The more common construction of this clause in payer amendment notices runs the other way, suspending the change until the objection is resolved. Acuity has not reviewed the underlying notice and cannot confirm that the excerpt reflects its operative text. Acuity has asked Amerigroup which reading governs.
The distinction matters because the alternative to objecting may be losing the contract outright. Asked in the post’s comments whether objecting has been leading to terminations, APG replied that it had not heard of any Amerigroup terminations tied to the amendment, and noted that it is probably too early to know. The precedent is close at hand. CareSource’s March notice told Georgia providers that an objection could trigger termination 90 days after receipt, and an Indianapolis ABA provider removed from the Anthem Medicaid network in April shut down two months later, citing that termination alongside Medicaid payment holds and credentialing backlogs.
The rate notice is the third change Amerigroup has made to Georgia autism services this year, and the only one it has not announced publicly. On March 9, the company posted a notice to its Georgia provider news site saying that effective April 1 it would revise reimbursement for Autism Spectrum Disorder Services to align with Georgia Medicaid reimbursement, and that it would retroactively reprocess claims with dates of service on or after December 1, 2025. That notice said the change would not affect member benefits, eligibility, or access. It did not say whether the alignment moved rates up or down.
On August 10, nine days before APG’s post, Amerigroup published a second notice revising how providers submit prior authorization requests for ABA treatment and reassessments, describing the changes as an alignment with traditional Medicaid intended to reduce administrative workload. Requests move to the state’s GAMMIS portal. Treatment requests may be submitted up to 30 days before the current authorization ends, reassessments cannot be authorized more than 60 days before the end of the current treatment plan, reviewers will adjust start dates that fall outside that window, and backdating is not permitted.
Those authorization changes take effect September 1, 2026, the same date by which APG has advised providers to get their rate objections delivered. Whatever the reduction turns out to be, Georgia ABA providers will absorb it in the same month they change how they request authorization.
The sequence carries a consistent stated rationale. Both public notices describe alignment: reimbursement with Georgia Medicaid reimbursement in April, authorization with traditional Medicaid in September. If the April action brought Amerigroup’s ABA reimbursement to the published state schedule, a further reduction would move it below that schedule, the position CareSource took in May. The April and August changes also reached providers through the ordinary provider communications channel, where any provider could find them. The one APG describes did not.
Why Nothing Stops a Georgia CMO From Cutting ABA Rates Below the Fee Schedule
The reason a Georgia managed care plan can do this at all is that nothing requires it not to. The Department of Community Health publishes a fee schedule for Adaptive Behavior Services, but no Georgia statute or regulation obligates a care management organization to reimburse at or above it. Rates are set in individual network contracts, and the current generation of CMO contracts was signed without rate-floor language. That gap is what APG identified after meeting with the Department in April, and it is what allowed CareSource to move to 80 percent of the schedule in May. APG has been pushing for a floor to be written into the next generation of contracts, which is one reason the unresolved procurement matters beyond the question of which plans win it.
What that schedule actually pays is a matter of public record. Georgia prices Adaptive Behavior Services by practitioner level rather than by procedure code, in 15-minute units. On the fee schedule released October 8, 2025, treatment delivered in a clinic pays $15.58 per unit at the Registered Behavior Technician tier, $20.91 at the Board Certified Assistant Behavior Analyst tier, $30.91 at the Board Certified Behavior Analyst tier, $40.14 for a Psychologist or Board Certified Behavior Analyst-Doctoral, and $59.96 for a Physician or Psychiatrist. The same ladder runs across the assessment and treatment codes, including 97151, 97152, 97153, 97154, and 97155. The family and group guidance codes, 97156, 97157, and 97158, are priced separately and considerably lower, topping out at $26.10.
Measured against that schedule, the CareSource amendment has a concrete value: 80 percent of $15.58 is $12.46 for a 15-minute unit of technician-delivered treatment in a clinic. How far the Amerigroup notice moves the same figure is not yet known.
The underlying schedule has barely moved. Georgia’s Adaptive Behavior Services rates have risen roughly three percent since the benefit launched in 2018, an adjustment authorized in the FY 2026 budget and implemented through State Plan Amendment 25-0008, which the federal Centers for Medicare and Medicaid Services approved on October 7, 2025 with a July 1, 2025 effective date. The schedule now in force was posted to the GAMMIS provider portal the following day.
Coverage rules for the benefit, which Georgia has provided to Medicaid members under 21 since January 1, 2018 under Early and Periodic Screening, Diagnostic, and Treatment, are set out in the state’s Part II Policies and Procedures for Autism Spectrum Disorder Services, last updated July 1, 2026.
Georgia also pays more outside the clinic than inside it, at every tier. Technician-delivered treatment pays $18.69 out of clinic against $15.58 in clinic, a 20 percent differential, and the gap runs wider at some higher tiers, reaching $76.31 against $59.96 at the physician level. Telehealth pays the in-clinic rate. That differential is what the vetoed parity appropriation was written to close, and it is the reason clinic operators say they compete for staff at home-based wage levels while billing at the clinic rate.
Providers also lost their most direct route to relief this spring. Governor Brian Kemp vetoed $15.86 million in clinic rate parity funding in May, ending a two-year campaign to close the gap between home-based and clinic-based reimbursement. The veto was part of a broader round of budget cuts that fell heavily on state health agencies.
Georgia ABA Providers Have Nowhere to Move Medicaid Volume Before June 2027
Amerigroup lost its bid to keep Georgia Families business in December 2024, and its appeal was denied in January 2026. It is still here. The Department of Community Health has said the procurement remains in its protest phase pending a Notice of Award and that it is extending the Amerigroup, CareSource, and Peach State contracts through June 30, 2027. The July 1, 2026 launch the incoming plans had targeted did not happen, the state has not published a member transition date, and Amerigroup, CareSource, and Peach State remain the three Georgia Families plans.
That removes the usual response to a rate cut. Providers who object and lose an Amerigroup contract cannot move the volume, because Humana, Molina, and UnitedHealthcare are not yet operating, and CareSource, the only incumbent that won, cut its own rates in May. Acuity has previously reported that Amerigroup’s credentialing and claims processing deteriorated after the award decision, with Georgia practices describing months of unpaid claims and no working channel to escalate them.
The financial floor underneath Georgia’s independent providers is already thin. A five-state operator headquartered in the state filed for Chapter 11 in May, with short-term merchant cash advance debt dominating its creditor list and no payer appearing among its creditors, a profile that points to cash flow rather than clawback. Provider advocates have argued in other states that rate reductions are the wrong instrument for the program integrity concerns payers cite. State programs have moved in both directions this year: Virginia raised waiver behavior analyst rates while capping state plan hours in July.
Neither the size of the Amerigroup reduction nor its effective date has been disclosed publicly, and it is not clear whether the amendment reaches only ABA codes or all covered services, as the CareSource amendment did. The Department of Community Health has not said whether it reviewed the change.
Providers who received the notice have two practical steps in front of them. Confirm the address Amerigroup has on file, since APG’s post indicates misdirected notices are the explanation for organizations that have not received one, and get any objection into certified mail well ahead of the date they intend it to be effective. Providers should consult counsel and their state association before responding.
This is a developing story. Acuity will update as Amerigroup responds and as the scope of the amendment becomes clear.
