Selling, buying, or expanding an ABA practice in Wisconsin: the license, the records, and the deal

Change of ownership: equity versus asset in Wisconsin

Wisconsin's equity-versus-asset decision turns on the DHS 35 certification, because Wisconsin uniquely codifies how a change of ownership is handled in the certification rules.

• Equity sale. The buyer acquires the certified entity, which keeps its DHS 35 certification and its ForwardHealth enrollment, and the change is handled through the DHS 35 change-of-ownership provision, with ForwardHealth ownership updated.
• Asset sale. The buyer takes assets but not the certified entity, so the DHS 35 certification does not simply pass; the buyer must hold or obtain its own certification and re-enroll with ForwardHealth, following the rule-specified steps, including the records-transfer provision.
• The codified mechanics. Because the DHS 35 rules specify both a change-of-ownership process and a records-transfer process, the deal must be planned around those provisions rather than around general agency practice, which is unusual and helpful for sequencing.

The first question in a Wisconsin deal is whether the structure preserves the DHS 35 certification and the ForwardHealth enrollment, and how the codified change-of-ownership and records-transfer steps apply.

How the DHS 35 certification and credentials move

Two layers matter. Clinician credentialing runs through the Department of Safety and Professional Services, and those credentials follow the clinicians. The organizational layer is the DHS 35 outpatient mental-health clinic certification, which commonly serves as the eligibility gate for Medicaid, BadgerCare, and the state insurance mandate, and which attaches to the certified entity (Wis. Admin. Code DHS 35; DHS 35.06). The DHS 35 rules expressly address change of ownership and the transfer of clinical records, so the certification and those rule steps are the central organizational deliverable in a deal; a practice should confirm whether it operates under DHS 35 certification, since that determines the path. The certification does not transfer like a deed; it is handled through the rule's change-of-ownership provision.

Expanding into Wisconsin: certification and enrollment

For an out-of-state operator, Wisconsin entry centers on the DHS 35 certification:

• Foreign registration or a parallel entity. The operator registers the home-state entity or forms a Wisconsin entity.
• DHS 35 certification and credentials. The clinicians obtain DSPS credentials, and the entity obtains the DHS 35 outpatient mental-health clinic certification where that is the path to Medicaid, BadgerCare, and insurance-mandate billing.
• ForwardHealth enrollment. The entity enrolls with ForwardHealth, noting the behavioral-treatment benefit and the rendering-provider requirements for certain codes.

The practical rule for entry is that the DHS 35 certification, not just corporate registration, gates billing, so build the expansion around obtaining it and the ForwardHealth enrollment.

Ownership restructuring on entry

Wisconsin professional-entity and corporate-practice considerations can require an ownership or management structure to be adjusted on entry. These ownership-side questions are addressed on the Wisconsin ownership page and the Wisconsin entity page; the transaction point is that the deal or expansion may require the ownership structure to be arranged to satisfy Wisconsin rules and the DHS 35 certification requirements, with disclosures consistent across ForwardHealth and the certification.

Medicaid re-enrollment through ForwardHealth

Wisconsin Medicaid, administered through ForwardHealth, runs enrollment and change of ownership, and for a DHS 35-certified clinic the certification and the codified change-of-ownership provision are part of the path. An equity change generally updates ownership on the existing ForwardHealth record and is handled through the DHS 35 change-of-ownership provision; an asset deal generally requires the new entity to hold the certification and enroll with ForwardHealth. A 2025 federal audit affecting behavioral-treatment payments and a rendering-provider requirement for certain codes affect the acquired business and should be diligenced, but the enrollment mechanics follow the equity-versus-asset choice and the DHS 35 rules (ForwardHealth; Wis. Admin. Code DHS 35.09). Federal ownership-disclosure rules apply.

Records custody under the codified transfer rule

Client records must remain with a qualified custodian, and Wisconsin both protects them strongly and codifies their transfer. Treatment records are confidential under the mental-health records statute and its administrative rules, federal substance-use rules may apply, and records must be retained for at least seven years, with the longer minor-retention rule controlling for pediatric clients; importantly, the DHS 35 rules specify how records are transferred on a change of ownership, so the transfer follows a defined process (Wis. Stat. Section 51.30; Wis. Admin. Code DHS 92; Wis. Stat. Section 146.819; Wis. Admin. Code DHS 35.23; 42 C.F.R. Part 2). In an equity sale the records stay with the entity; in an asset sale, the codified transfer process must be followed and a qualified custodian must remain responsible. Records custody is a central deal item.

Non-compete enforceability in Wisconsin

Wisconsin enforces reasonable non-competes but is strict in a way that demands precise drafting.

• The reasonableness requirement. Under Wis. Stat. Section 103.465, a non-compete is lawful and enforceable only if the restrictions are reasonably necessary to protect the employer, judged on duration, territory, and scope (Wis. Stat. Section 103.465).
• The all-or-nothing rule. Critically, a covenant that imposes an unreasonable restraint is void and unenforceable even as to any part of the covenant that would be a reasonable restraint, so Wisconsin courts do not modify or blue-pencil an overbroad covenant; the entire covenant fails. This makes Wisconsin one of the strictest states for drafting, since a single unreasonable term can void the whole covenant.
• The sale-of-business context. Because of the all-or-nothing rule, sale-of-business covenants with selling owners, which are analyzed under different principles and given more latitude, are the safer and more reliable tool for protecting goodwill, alongside carefully drafted confidentiality and non-solicitation provisions.

The practical rule is that a Wisconsin buyer must draft any employee non-compete with great precision, because an overbroad term voids the entire covenant, and should lean on sale-of-business covenants and confidentiality to protect value, with counsel confirming current law.

Diligence flags specific to Wisconsin

The state-neutral diligence workstreams are covered in the ABA due diligence playbook. The items that change specifically in Wisconsin are:

• Which track, and the diagnostic line. Confirm whether the target is ABA only, in which case the Medicaid asset is its ForwardHealth behavioral treatment enrollments, or also diagnoses or provides psychotherapy in house, in which case the DHS 35 certification and its codified transfer steps join the deal and the diagnostician's own enrollment must survive the structure. The two tracks have different change-of-ownership mechanics and the deal should be sequenced to whichever the practice actually runs.
• DHS 35 certification. Confirm whether the target holds DHS 35 certification, its conditions, and how the codified change-of-ownership and records-transfer provisions apply to the structure.
• Covenant validity. Confirm existing non-competes are narrowly and precisely drafted, since an overbroad term voids the whole covenant.
• Audit and rendering-provider exposure. Confirm exposure to the 2025 federal audit findings on behavioral-treatment payments and the rendering-provider rule for certain codes.
• Records retention and transfer. Confirm the seven-year and minor-retention compliance and the codified transfer process.

Reading the Wisconsin transaction friction

Putting the pieces together, Wisconsin is a moderate-friction state with two distinctive features that shape the deal. The DHS 35 outpatient-clinic certification applies where the practice runs a diagnostic or psychotherapy line, and for a certified practice the codified DHS 35 change-of-ownership and records-transfer steps are a central organizational deliverable, handled differently in equity and asset structures. The non-compete statute is the second distinctive feature: an overbroad covenant is void in its entirety with no judicial modification, so precise drafting is essential and sale-of-business covenants are the safer tool. ForwardHealth runs Medicaid, with audit and rendering-provider items to diligence, and records carry strong confidentiality, a seven-year retention floor, and a codified transfer process. The practical read is a deal built around the DHS 35 certification with carefully drafted covenants. None of this is legal, tax, or financial advice; it is the structure you would plan around with counsel and advisors.

How this connects to the rest of your compliance stack

This transaction page pulls together threads from across the guide:

• Facility and licensing. The DHS 35 certification and DSPS credentialing are detailed on the Wisconsin facility-licensure page and the Wisconsin licensing page.
• Ownership and entity. The professional-entity rules are on the Wisconsin ownership page and the Wisconsin entity page.
• Medicaid. The ForwardHealth behavioral-treatment benefit, the audit finding, and the rendering-provider rule are covered on the Wisconsin Medicaid page.
• The state-neutral deal mechanics. Diligence, deal structures, private equity, expansion, and wind-down are covered on the spoke's concept pages, linked below.

Sequencing a Wisconsin deal or expansion

1. Confirm the DHS 35 certification. Determine whether the practice operates under DHS 35 certification, which sets the change-of-ownership and records-transfer path.
2. Choose equity versus asset. Decide the structure, noting equity preserves the certification and enrollment while asset requires the buyer to hold the certification and re-enroll.
3. Apply the codified CHOW and records steps. Follow the DHS 35 change-of-ownership and records-transfer provisions and update ForwardHealth.
4. Draft covenants precisely. Because an overbroad covenant is void entirely, draft narrowly and rely on sale-of-business covenants and confidentiality.
5. Settle records retention and transfer. Ensure a qualified custodian, the seven-year and minor-retention compliance, and the codified transfer process.
6. Diligence audit and coding exposure. Confirm the 2025 audit findings and the rendering-provider rule and their effect on revenue.
