If Your Clinic Diagnosed the Child, South Carolina Won't Pay You to Treat Them

South Carolina's Autism Spectrum Disorder Services Provider Manual, in force for dates of service on or after July 1, 2026, puts one line in its non-covered list that reorganizes a business model. Medicaid will not reimburse:

“ABA services rendered by any provider/group/clinic that is connected to the provider/group/clinic that conducted the member's Comprehensive Developmental Evaluation and rendered the autism spectrum disorder diagnosis that facilitated the members eligibility for ABA services.”

This isn't a paperwork rule

Most of what states have added this year tightens how you evidence a service you were already going to deliver. This one decides whether you may deliver it at all. Diagnose-and-treat under one roof — an in-house psychologist or developmental pediatrician feeding the ABA schedule — has been a standard way to shorten the gap between evaluation and treatment. In South Carolina Medicaid it is now the thing that makes the treatment claim non-covered.

SCDHHS grounds it in ethics rather than fraud, and names its authorities: the APA's Ethical Principles of Psychologists and Code of Conduct, Standards 3.05 (Multiple Relationships) and 3.06 (Conflict of Interest), and the BACB's Ethics Code for Behavior Analysts, Standard 1.11 (Multiple Relationships).

What else moved in the same list

• ASD diagnoses conferred by telehealth are not considered valid for South Carolina Medicaid. Neither are autism measures and tests administered via telehealth, or the reports resulting from them.
• ABA rendered by the member's responsible adult — biological, adoptive or foster parent, guardian, court-appointed conservator, family by birth or marriage — is a conflict of interest and is not billable.
• ABA aimed at symptoms outside the core features of ASD — the manual names impulsivity from ADHD, excessive worry from anxiety, reading difficulty from a learning disability — is non-covered. Providers are told to coordinate with educators and licensed therapists rather than address those targets through ABA.

The limits

The manual doesn't define “connected.” Common ownership plainly qualifies; a referral relationship between separately owned entities is arguable, and the document gives no test for shared management, shared premises or a common parent. South Carolina's Medicaid managed care organizations handle authorization, coverage and reimbursement for enrolled members, so the first reading you get in practice will be an MCO's, not the agency's. And the rule sits in a list that opens with a carve-out: activities on it may still be covered where the QIO approves them at prior authorization to address a limited, clearly defined goal tied to a core feature of ASD.

What you must know or do

• Owners: list every child on your current South Carolina Medicaid census whose ASD diagnosis came from an entity you share an owner, a parent company or a managing employee with. That list is your exposure, and it is countable this week.
• Owners with a diagnostic arm: decide which side you keep for those members. Referring the evaluation out and keeping treatment is the change most practices will make; the alternative is keeping the evaluation and handing the ABA to an unconnected provider.
• Intake: stop accepting a telehealth-conferred ASD diagnosis as the basis for a South Carolina Medicaid authorization. Check the last three months of new starts for one, because that record does not become valid later.
• Clinical directors: pull any treatment plan whose goals target ADHD, anxiety or academic skills. Those goals are non-covered unless they tie to a core feature of ASD, and they are visible to a reviewer reading the plan.
