A LEARN Unit Sued MassHealth Over a $943K Supervision-Ratio Clawback

On September 23, 2026, Autism Spectrum Therapies, LLC, a LEARN Behavioral company, sued Massachusetts' Executive Office of Health and Human Services and seven managed care entities in Suffolk Superior Court (Business Litigation Session, No. 2684CV02851). The plans have demanded $942,862.89 back for calendar 2024 ABA claims because the provider's technician hours ran past a 1:10 supervision ratio. It has already paid $117,045.50 under protest.

We've covered a plan that writes the ratio into its own notice, Meridian in Illinois. This case asks a different question: what happens when the ratio sits in a document the provider argues was never a payment condition at all. The answer will matter well beyond Massachusetts, because the two arguments in the complaint are ones any owner can test against their own payers now.

How the plans calculated it

• The method compares paid units of 97155 with paid units of 97153. Other supervision, billed or not, doesn't count.
• Between 10:1 and 19:1, technician hours above the 10:1 line are recouped. At 20:1 or worse, all technician hours are.
• The complaint's example: 150 technician hours against 10 analyst hours keeps payment for 100 and owes back 50.
• Carelon's demand across the four plans it administers is $857,002.24. Point32Health's is $85,860.65, covering 14 members.

The ratio traces to Massachusetts Behavioral Health Partnership performance specifications from 2016. The state Inspector General's March 2024 review put up to $17.3 million in overpayments on ABA providers, $16,761,445 of it tied to the 1:10 ratio.

The two arguments

• An unadopted rule. The ratio was never published, put out for comment or adopted as a regulation, the complaint says, and the specifications didn't define case supervision or limit it to 97155. Carelon's position, per the complaint, is that provider manuals and the provider agreement incorporate the specifications by reference.
• The 12-month bar. M.G.L. c. 118E, § 38A bars MassHealth and its contracted plans from retroactively denying a behavioral health claim once 12 months have passed since it was submitted. The exceptions include fraud, payment by another payer, services not delivered, and services "not delivered in accordance with MassHealth regulations." The complaint says no defendant has alleged any of them.

The limits

Nothing has been decided. As of early October no hearing was set and no defendant had appeared, and the company hasn't asked for emergency relief. MassHealth says it can't comment on active litigation. We couldn't open the court docket directly; the case details here are the ones two independent reports of the complaint agree on.

The rules have also moved since 2024. The revised MBHP/Carelon specification, updated February 15, 2026, says LABA supervision of technicians must be "no less than 10 percent of direct service hours" and shouldn't exceed 25 percent without documented clinical rationale, with at least one hour a month for members getting 10 hours or less. MassHealth's All Provider amendments, effective July 31, 2026, "clarify that providers participating in managed care are required to adhere to performance specifications" in plan contracts. Whatever the court decides about 2024, for services after that date the regulation itself points to the specifications.

What you must know or do

• Massachusetts owners and billers: run paid 97155 units against paid 97153 units per member, per plan, for 2025 and 2026 so far. That's the plans' own arithmetic. Supervision that wasn't billed as 97155 won't show up in it.
• Massachusetts owners: if a demand arrives, put each claim's submission date next to it. For anything over 12 months old, check whether the notice names one of § 38A's exceptions, and whether you got the written explanation and 30 days to submit documentation that § 38A(b) requires.
• Owners in every state: for each payer that enforces a supervision ratio, find where it's written: your contract, a state regulation, a provider manual or a performance specification. Then check whether that document says how the ratio is measured and what happens if you miss it. Do it before a demand arrives.
• Clinical directors: schedule 97155 at or above 10% of 97153 for every client in each authorization period, and make up missed supervision inside that period. Under every version of this rule, that's the line.
