Does Louisiana Medicaid Allow PLPC, PLMFT and LMSW Therapy?

Yes for the listed outpatient practitioners; they cannot bill independently

Louisiana Medicaid's Behavioral Health Services Manual expressly includes PLPCs, PLMFTs and LMSWs for outpatient therapy within their lawful scope and required board supervision. It also includes provisionally licensed psychologists (PLPs) and psychology interns effective October 1, 2026. The billing rule is specific: these clinicians may be the rendering provider on a claim when consistent with Title 46 and their practice acts, but may not directly bill Medicaid.

Reviewed October 30, 2026. This answer uses section 2.3, Outpatient Therapy by Licensed Practitioners, issued October 6, 2026, replacing September 8, 2026. It is the statewide outpatient framework, not an inference from a particular MCO's CPST policy. The enrolled billing arrangement, actual code, authorization and member's plan still matter.

Which licenses and trainees are actually named?

PLPC, PLMFT and LMSW: each must hold the required valid, current, unrestricted Louisiana license, work within the applicable scope and actively participate in supervision required by the relevant licensing board. A degree or pending application alone does not meet those requirements.

PLP: the manual requires a valid, current, unrestricted psychology-board license and board-required supervision. It describes assessment, individual/family/group therapy and psychological testing within scope.

Psychology intern: the person must be actively enrolled in an APA-approved internship program, work within the applicable scope and receive required supervision. The October 2026 addition does not automatically include counseling students, MSW students or every unlicensed graduate.

Whose NPI belongs on the claim?

The manual allows the listed provisional clinicians and psychology interns to be rendering providers while prohibiting their direct billing. That distinction means a supervisor's NPI is not automatically the correct rendering identity simply because supervision is required. The billing provider must be eligible for the particular service and the actual clinician's enrollment, provider type and specialty must match the authorized arrangement.

The manual lists eligible provider types and specialties, including mental health rehab agencies, mental health clinics/groups and specified practitioner types. Its LL labels for LMSWs, PLPCs, PLMFTs and psychology interns are specialty labels in that table, not a universal instruction to append an LL claim modifier. Use the Specialized Behavioral Health Fee Schedule and plan's claim instructions for the exact code.

What must be true before outpatient treatment is billed?

All services under this section must be authorized; treatment beyond the initial authorization needs reauthorization before delivery. The service must meet medical necessity and be within the clinician's lawful scope. Psychological testing specifically needs MCO prior authorization. Certain institutional services are included in the facility service and are not separately reimbursable under this outpatient section.

Supervision is an active licensing requirement, not merely a supervisor named on paperwork. The manual's permission does not replace the relevant board's rules or establish unrestricted commercial-insurance or Medicare billing.

How is this different from CPST?

The separate Mental Health Rehabilitation Services section, issued August 14, 2026, requires CPST staff to operate under an LDH agency license. Assessment and treatment planning require an LMHP. Other CPST components expressly include PLPC, PLMFT, LMSW, CSW, PLP and qualifying APA psychology interns.

That CPST staffing list is not interchangeable with the outpatient-therapy list. In particular, a CSW's inclusion in CPST does not establish inclusion in the ordinary outpatient list above. Conversely, the current outpatient rule provides direct evidence for PLPC/PLMFT/LMSW therapy rather than leaving the answer at CPST alone.
