The Maine Mirror Accountability Series — Article 4 of 7

🪞 THE MIRROR BRIEF

Federal auditors concluded Maine made improper and potentially improper Medicaid payments for rehabilitative and community support services because the state did not provide effective oversight. Maine DHHS’s response: “AGREE.” Records obtained by The Maine Mirror also show the state acknowledged problems with provider guidance and training and said existing Section 28 rules contained “outdated, ambiguous, and inaccurate provisions.” Maine committed to replacing those rules as part of its corrective-action plan.

The first three articles in this series followed tens of millions of dollars in improper and potentially improper Medicaid payments and federal concerns about unreliable documentation supporting services for children with autism.

But those findings lead to a larger question:

How did these problems happen in the first place?

One federal finding obtained by The Maine Mirror points directly toward oversight by the state itself.

Under Finding 26-A-01-033.03, federal auditors concluded:

“The State agency made improper and potentially improper payments because it did not provide effective oversight of FFS Medicaid payments for RCS services.”

Maine’s response to that finding was:

“AGREE.”

And the state’s corrective-action records go further.

Maine said it was updating rules governing these services, expanding provider guidance and training, and replacing existing Section 28 rules because those rules contained “outdated, ambiguous, and inaccurate provisions.”

Federal Auditors Pointed to Maine’s Oversight

The finding does not merely identify questionable claims or provider documentation.

It identifies state oversight as a cause of improper and potentially improper payments.

Federal auditors recommended that Maine DHHS provide additional guidance to providers about documenting RCS services, specifically including information necessary in session notes to support the services provided, billable service time and signature requirements.

(Federal Finding 26-A-01-033.03 states that Maine made improper and potentially improper fee-for-service Medicaid payments for RCS services because the state “did not provide effective oversight.” Federal auditors recommended that Maine DHHS provide additional guidance to providers concerning documentation of services, billable service time and signature requirements.

The finding adds an important layer to the documentation problems examined in Article 3.

Federal auditors had already identified approximately $22.4 million in potentially improper payments and warned that cloned or otherwise unreliable session notes indicated children with autism may not have received the type of RCS services needed.

Finding 26-A-01-033.03 moves upstream:

What responsibility did Maine have for overseeing the system in which those claims were submitted and paid?

Maine DHHS: “AGREE”

The state’s response appears directly beneath the finding.

Asked whether it agreed or disagreed, Maine answered:

“AGREE.”

Maine said it was in the process of updating state rules governing RCS services and would issue guidance to providers concerning documentation requirements.

The state also committed to continued training and technical assistance, including initial training for new providers.

Unlike the $28.8 million refund recommendation examined in Article 2, where Maine partially agreed, there is no such qualification here.

On the oversight finding, Maine agreed.

Maine Said Its Existing Rules Were “Outdated, Ambiguous, and Inaccurate”

Maine’s detailed corrective-action plan shows what the state intended to do about it.

First, Maine required newly enrolling RCS providers to receive initial training from the state’s Provider Relations Team before delivering services and submitting claims to MaineCare. The estimated completion date was March 1, 2026.

The second corrective action is particularly significant.

Maine committed to repealing the existing Chapter II and Chapter III Section 28 rules governing these services and replacing them with a new Chapter II, Section 28 governing Adaptive Behavior Services for Children.

The state explained why:

“because these rules contain outdated, ambiguous, and inaccurate provisions.”

Maine said the replacement would update and clarify provisions, simplify the rule, change service names, improve provider understanding and compliance, and address Maine’s December 2024 settlement with the U.S. Department of Justice concerning children’s behavioral health services.

The estimated completion date was April 24, 2026.

Maine also committed to sending providers electronic guidance and reminders concerning proper documentation by May 1, 2026.

Finally, the state said it would hold biannual training sessions for RCS providers covering service-delivery and documentation requirements, with providers required to attend at least one session annually. That step carries an estimated completion date of October 30, 2026.

The corrective actions tell their own story:

Training. Documentation guidance. Technical assistance. Replacement of the underlying rules.

What the Records Establish

These documents do not establish that outdated or ambiguous rules caused every improper payment identified by federal auditors.

They do not absolve providers of responsibility for complying with applicable requirements.

And they do not establish that every documentation problem resulted from inadequate state guidance.

What they do establish is consequential enough:

Federal auditors concluded Maine made improper and potentially improper payments because it “did not provide effective oversight.”

Maine agreed.

And when Maine laid out how it intended to correct that problem, the state acknowledged that existing rules contained provisions it considered “outdated, ambiguous, and inaccurate.”

That expands the accountability picture beyond individual providers.

Providers were responsible for properly documenting services and submitting compliant claims.

But Maine was responsible for establishing the rules, providing guidance and training, and effectively overseeing the Medicaid payments it made.

The federal finding—and Maine’s response—places responsibility on both sides of that system.

The Deadlines Give the Public Something to Measure

Maine’s corrective-action plan established specific benchmarks:

March 1, 2026 — initial training requirement for newly enrolling RCS providers.

April 24, 2026 — repeal and replacement of existing Section 28 rules.

May 1, 2026 — electronic provider guidance and reminders concerning proper documentation.

October 30, 2026 — biannual provider training, with RCS providers required to attend at least one session annually.

As of this article’s August 27 publication date, the first three estimated completion dates have passed.

The October deadline has not.

The records examined here establish what Maine committed to do and when it expected those actions to be completed. They do not, by themselves, establish whether each past-due action occurred on schedule.

That leaves specific questions for continued reporting:

Were the Section 28 rules replaced by April 24? What changed? Did providers receive the promised documentation guidance? What training has occurred? And how will Maine determine whether these reforms prevent the problems identified by federal auditors from happening again?

Those questions can now be measured against commitments contained in Maine’s own records.

The Accountability Question Is Getting Bigger

The progression through the first four articles matters.

Federal auditors estimated at least $45.6 million in improper payments.

They identified another approximately $22.4 million in potentially improper payments.

They raised concerns about cloned or otherwise unreliable session notes.

Now the records show auditors also concluded Maine “did not provide effective oversight” of the RCS payments—and Maine agreed.

That does not eliminate provider accountability.

It establishes that the accountability question extends to the system responsible for setting the rules and overseeing the money.

And the next federal finding raises an even larger question about how closely that system had historically been watching payments after they were made.

Next in The Maine Mirror Accountability Series — Article 5 of 7

Maine’s Autism-Service Program Began in 2010. Federal Auditors Say a Statewide Post-Payment Review Never Happened.

The next finding moves beyond individual claims, documentation and provider guidance.

Federal records state that Maine had not performed a statewide post-payment review of RCS services since the program began in 2010.

The records also reveal what Maine told federal officials it would finally do about it.

Article 5 of 7 continues next.
