The Maine Mirror Accountability Series — Article 5 of 7

🪞 THE MIRROR BRIEF

Federal auditors found that Maine had not performed a statewide post-payment review of Medicaid-funded rehabilitative and community support services since the program began in 2010. Maine DHHS responded “AGREE.” Records obtained by The Maine Mirror show the state has now committed to reviewing 30 Section 28 providers per year—but its plan projects that all providers will not have undergone a post-payment review until SFY2029.

For more than a decade, MaineCare paid providers to deliver rehabilitative and community support services, known as RCS services, to children with autism and other developmental needs.

Federal auditors have now documented something striking about how those payments were overseen after the money went out the door.

According to Finding 26-A-01-033.04, Maine “had not performed a statewide post payment review” of payments to RCS providers to verify compliance with federal and state documentation and claim requirements since the program began in 2010.

Maine did not dispute the finding.

Its response:

“AGREE.”

And the corrective-action records obtained by The Maine Mirror through Maine’s Freedom of Access Act show that MaineCare has now committed to a review process that is expected to continue through State Fiscal Year 2029.

No Statewide Post-Payment Review Since 2010

The federal finding is direct.

Auditors wrote:

“The State agency had not performed a statewide post payment review of payments to providers of RCS services to verify that providers complied with federal and state requirements related to documentation and claim requirements since the program began in 2010.”

Federal auditors recommended that Maine DHHS periodically conduct statewide post-payment reviews of Medicaid payments for RCS services.

Those reviews, auditors said, should include examinations of medical records.

The recommendation also called for additional provider training in areas where errors were identified through those reviews.

(Federal Finding 26-A-01-033.04 states that Maine had not performed a statewide post-payment review of payments to RCS providers to verify compliance with federal and state documentation and claim requirements since the program began in 2010. Federal auditors recommended periodic statewide post-payment reviews, including medical-record reviews and additional training where errors are identified.

The significance becomes clearer when placed alongside the findings already examined in this series.

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

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

They flagged cloned or otherwise unreliable session notes.

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

And now another federal finding establishes that a statewide post-payment review designed to verify provider compliance had not been performed since the RCS program began in 2010.

What Is a Post-Payment Review?

The distinction between reviewing a claim before payment and reviewing payments afterward matters.

A post-payment review gives a program an opportunity to examine claims and supporting records after money has been paid and determine whether providers actually complied with program requirements.

In this case, the federal recommendation specifically called for reviewing medical records as part of that process.

The purpose is straightforward: identify errors, determine recurring problems and use those findings to improve oversight, provider guidance and training.

According to the federal finding, Maine had not conducted that type of review statewide for RCS services since the program’s beginning.

The records do not establish that Maine performed no oversight of RCS providers whatsoever during that period.

They establish something narrower and important:

Maine had not performed the statewide post-payment review described by federal auditors.

That distinction matters.

Maine DHHS: “AGREE”

Maine’s response contains no dispute over the finding.

Asked whether the state agreed or disagreed, Maine answered:

“AGREE.”

The Office of MaineCare Services Program Integrity Unit said it would plan annual reviews of a sample of providers delivering RCS services as part of its yearly strategic review plan for the next several years.

Maine also said Program Integrity would identify recurring issues discovered during those reviews and use them to inform provider training and guidance.

(Maine DHHS’s response to Finding 26-A-01-033.04 records the state’s position as “AGREE.” MaineCare’s Program Integrity Unit said it would conduct annual reviews of a sample of RCS providers for the next several years and identify recurring issues to inform provider training and guidance. Source: Record obtained from Maine DHHS through a Freedom of Access Act request.)

That response establishes the state’s proposed solution.

But the detailed corrective-action plan shows how long that solution is expected to take.

Thirty Providers Per Year — Through 2029

Maine’s corrective-action plan contains two steps.

First, MaineCare Program Integrity said it would include a sample of Section 28 providers delivering RCS services in its SFY2027 Annual Review Plan.

The plan was to be developed in spring 2026 for the state fiscal year beginning July 1, 2026.

Samples would also be included in the annual review plans for SFY2028 and SFY2029.

The corrective-action document lists an estimated completion date of June 15, 2026 for that planning step.

The second step establishes the scope of the actual provider reviews:

“Program Integrity will conduct reviews of thirty (30) Section 28 providers per year until all Section 28 providers of RCS services have undergone a post-payment review, which should occur in SFY2029.”

The estimated completion date listed for that commitment is:

December 31, 2029.

(Maine DHHS’s detailed corrective-action plan says MaineCare Program Integrity will include Section 28 RCS providers in annual review plans for SFY2027, SFY2028 and SFY2029 and conduct post-payment reviews of 30 Section 28 providers per year until all providers have undergone a review. The plan states that should occur in SFY2029 and lists an estimated completion date of December 31, 2029. Source: Record obtained from Maine DHHS through a Freedom of Access Act request.)

That creates a remarkable timeline.

2010: The RCS program begins.

2026: Federal auditors report that Maine has not performed a statewide post-payment review since the program began.

2026: Maine agrees with the finding and commits to annual provider reviews.

2027–2029: Section 28 providers are scheduled to be incorporated into annual review plans.

2029: Maine projects all RCS providers will have undergone a post-payment review.

In other words, according to Maine’s own corrective-action timeline, the process created in response to the federal finding extends nearly two decades beyond the program’s beginning.

What This Finding Does — and Does Not — Establish

The wording of the underlying record is important.

The finding does not establish that Maine conducted no oversight whatsoever between 2010 and 2026.

It does not establish that every RCS provider went unreviewed.

And it does not establish that every payment made during that period was improper.

What the federal finding specifically establishes is that Maine had not performed a statewide post-payment review of payments to RCS providers to verify compliance with documentation and claim requirements since the program began in 2010.

Maine agreed with that finding.

That is consequential on its own.

Post-payment reviews are one mechanism through which recurring billing, documentation and compliance problems can be identified after public money has already been spent.

The absence of the statewide review described by auditors becomes particularly relevant when considered alongside the other findings in this audit.

Federal auditors later identified tens of millions of dollars in improper and potentially improper payments, unreliable session notes and ineffective state oversight.

The records do not prove that conducting statewide reviews earlier would have prevented those problems.

But they raise an unavoidable accountability question:

What might Maine have discovered if statewide post-payment reviews had been occurring throughout the program’s history?

The records currently available cannot answer that.

A New Oversight System After the Audit

Maine’s corrective-action plan effectively creates a new benchmark for accountability.

The state has committed to reviewing 30 Section 28 providers per year until every provider has undergone a post-payment review.

Those reviews are also supposed to serve another purpose.

Maine says recurring issues identified through Program Integrity reviews will inform future provider training and guidance.

That creates measurable questions going forward:

How many providers have now been reviewed?

What recurring problems are being identified?

How many reviews result in findings?

Are overpayments being discovered?

Are providers being required to repay MaineCare?

And what changes to training and guidance result from what Maine finds?

Those answers will determine whether the corrective-action plan becomes simply another document—or a meaningful change in how Maine oversees these services.

Sixteen Years Without a Statewide Review

Across the first five installments of this series, the picture contained in the primary-source records has steadily widened.

The story began with $45.6 million in estimated improper payments.

Then came the $28.8 million federal refund recommendation.

Then another $22.4 million in potentially improper payments and concerns involving cloned or otherwise unreliable session notes.

Then the finding that Maine did not provide effective oversight, which Maine agreed with while acknowledging that existing rules contained outdated, ambiguous and inaccurate provisions.

Now the records establish another piece of that oversight structure:

A statewide post-payment review had not occurred since the RCS program began in 2010.

Maine agreed.

And the state’s solution is now scheduled to unfold through 2029.

That leaves a question larger than any individual claim:

How did a Medicaid program serving vulnerable Maine children operate for approximately 16 years without the statewide post-payment review federal auditors say should have been occurring?

And as this series moves toward its conclusion, another question becomes increasingly important:

Who knew what—and when?

Next in The Maine Mirror Accountability Series — Article 6 of 7

The audit findings tell us what federal reviewers eventually discovered.

But the records obtained by The Maine Mirror also document what happened after those findings reached Maine and federal officials—including the communications, deadlines and corrective-action process that followed.

Article 6 will continue tracing that accountability chain through the primary-source record.

Article 6 of 7 continues next.
