Behavioral health and therapy groups

Behavioral health is the vertical where the MSO-PC structure is hardest to get right, for one reason: a single behavioral health group routinely employs six or more distinct license types, and who may own the professional entity depends on which of them the entity is organized to practice.

​

The licensure problem

A typical group employs some combination of: Each is licensed by a different board under a different statute. Whether one professional entity can employ all of them, and who may own it, varies dramatically by state.

​

The structural patterns

There is no general answer, and this is the most common structural error in behavioral health. Get a state-specific opinion before hiring across license types. A group that hires an LMFT into a physician-owned PC in a state that doesn’t permit it has a licensure problem, a billing problem, and potentially a CPOM problem simultaneously. See Multi-specialty considerations. Note that Oregon’s SB 951 carves out certain behavioral health arrangements from its MSO restrictions, another instance where the answer for behavioral health diverges from the answer for medicine in the same state.¹

​

Supervision billing

A defining operational feature. Pre-licensed clinicians, associates, interns, residents accruing supervised hours toward licensure, deliver a large share of care in many groups. Whether their services are billable, and under whose NPI, depends on:

• The payer. Medicare, Medicaid, and each commercial payer have different rules.
• The state. Supervision requirements and scope of practice are state law.
• The license type. An LCSW associate and a psychology intern may be treated differently.
• The supervision level. Direct versus general supervision, and documentation requirements.

​

Medicare’s expanding categories

Historically, Medicare did not enroll marriage and family therapists or mental health counselors, which pushed those clinicians out of Medicare-serving groups entirely. That changed — CMS established enrollment for marriage and family therapists and mental health counselors as Medicare providers effective January 1, 2024, following the Consolidated Appropriations Act, 2023.² Practical consequences:

• Groups can now enroll MFTs and MHCs and bill Medicare for their services
• The enrollment backlog for these newly eligible categories has been significant
• Verify current enrollment requirements and covered services with CMS rather than relying on pre-2024 guidance, which is now wrong

Psychiatrist opt-out remains common: a physician who has opted out of Medicare has a private contract with beneficiaries and does not bill Medicare. If your friendly owner or a key psychiatrist has opted out, that affects group enrollment in ways worth understanding before you build the model.

​

Parity law leverage

The Mental Health Parity and Addiction Equity Act requires that financial requirements and treatment limitations applied to mental health and substance use disorder benefits be no more restrictive than those applied to medical/surgical benefits.³ This is genuinely useful in appeals. Where a payer applies a limitation to behavioral health that it does not apply comparably to medical/surgical care — visit limits, prior authorization requirements, more restrictive medical necessity criteria, or network adequacy — parity is an argument, and it is a stronger one than a general medical necessity appeal. Ask for the plan’s comparative analysis of its nonquantitative treatment limitations. Plans are required to be able to produce one.

​

Telehealth-first structures

Behavioral health is the most telehealth-native vertical, and that shapes the corporate structure. A national telehealth behavioral group needs a professional entity in every state it serves, because the patient’s location governs licensure and practice rules. Telehealth changes the modality, not the jurisdictional analysis. See One PC per state. At fifty states, recruiting fifty genuinely engaged clinician-owners is a different problem than at three, which is why nominee-owner networks are most concentrated in this segment, and why it draws proportionate regulatory attention. If you go this route, give owners real documented duties they actually perform. See The friendly PC. PSYPACT streamlines interjurisdictional practice for psychologists across participating states, and other compacts exist for counseling and social work. They ease individual licensure. They do not create a national professional entity.

​

42 CFR Part 2, a stricter data regime

Substance use disorder treatment records from federally assisted programs are protected by 42 C.F.R. Part 2, which historically imposed consent requirements stricter than HIPAA. The rules were significantly revised to better align Part 2 with HIPAA following the CARES Act, with a compliance date in 2026 — verify the current requirements rather than relying on either the old regime or early summaries of the new one.⁴ Practical implications regardless of the current alignment:

• SUD records need separate handling in your EHR, with segregated access controls
• Consent and redisclosure rules are stricter than general HIPAA practice
• Your BAAs and vendor arrangements must account for it
• Billing and remittance data referencing SUD treatment is in scope

If any of your PCs deliver SUD treatment, treat Part 2 as a distinct compliance workstream. See HIPAA for MSO-PC operators.

​

Billing characteristics

• 837P with CPT codes for psychotherapy, evaluation, and management
• Time-based codes dominate — documentation must support the time billed, and this is a frequent audit finding
• Session frequency limits and prior authorization are common, and are where parity arguments apply
• Carve-outs, many plans administer behavioral health through a separate entity (Optum Behavioral Health, Carelon), requiring separate contracting and separate credentialing from the medical plan
• Common vendors: SimplePractice, TherapyNotes, Alma-style network platforms, noting the last is a different category, closer to a network than an EHR

​

Launch pitfalls

1. Hiring across license types before confirming the entity can employ them
2. Billing supervised services without confirming payer-specific rules
3. Missing behavioral carve-outs and contracting only with the medical plan
4. Relying on pre-2024 Medicare guidance for MFT and MHC enrollment
5. Under-documenting time on time-based codes
6. Treating SUD records like general PHI
7. Assuming telehealth avoids the per-state PC requirement
