Does Washington L&I Allow Supervised Student Therapy?

Does Washington L&I allow supervised student therapy?

Washington L&I has a defined student-supervision billing pathway, but it is not blanket approval for every associate therapist. Under its July 2026 rules, a qualifying student may perform services allowed by the applicable Department of Health rules and L&I service policy, with same-discipline direct supervision. The supervisor bills using their own L&I provider account number and co-signs the documentation. Mental-health services still have the separate provider, evaluation and authorization limits below.

Which program does this answer cover?

This guide concerns Washington workers’ compensation: State Fund claims and claims covered by self-insured employers. Chapter 17’s mental-health policies expressly do not apply to crime-victim claims. Chapter 2’s general student policy also discusses crime victims, but that does not transfer the workers’ compensation mental-health benefit rules to the separate Crime Victims Compensation Program. These are not Apple Health Medicaid or ordinary commercial-insurance rules.

Does an LMHCA, LMFTA or social-work associate automatically qualify?

No automatic approval follows from the associate credential alone. Chapter 2, pages 2-12–2-13, defines a student through clinical training in an accredited educational program governed by Department of Health rules. Its included categories extend to senior students, associate or interim-permitted students who have completed training but are not fully licensed, and clinical postgraduate trainees. The supervisor definition also requires an agreement with the student and their educational institution for clinical training.

The same policy separately excludes providers with temporary or interim professional licenses from its student definition. It also says agency-affiliated counselors are not students under the policy and cannot treat injured workers or crime victims. Those distinctions matter: the phrase about interim-permitted students cannot be used to erase the express exclusion for interim professional licenses. The chapter does not give an unconditional LMHCA, LMFTA, LSWAIC or LASWA approval list. Establish the actual training status, discipline and applicable Department of Health requirements before relying on the student pathway.

What must the supervisor do?

The supervisor must be licensed, have an active L&I provider account, supervise within their own discipline, and take responsibility for the student’s services. The student may perform only delegated services allowed by the applicable Department of Health rules; the supervisor determines competence. Services outside the student’s education or scope, or prohibited by L&I’s Medical Aid Rules and Fee Schedules, remain noncovered.

Direct supervision must meet the Department of Health requirements while the student performs the service. Chapter 2 permits direct supervision via telehealth, with modifier FR, when the service to the worker is allowed via telehealth. Services requiring in-person care also require in-person direct supervision. This is not permission to use occasional case review as a substitute for the required supervision.

Which licensed therapists may provide mental-health treatment?

Chapter 17, pages 17-6–17-8, lists psychiatrists, psychiatric APRNs qualified as psychiatric mental-health nurse practitioners, licensed clinical psychologists, and master’s-level therapists limited to LICSWs, LMFTs and LMHCs. Its treatment table allows psychotherapy by those categories. Psychiatrists, psychiatric APRNs and psychologists must join the Medical Provider Network, including when they do not serve as the attending provider, subject to the chapter’s initial-visit rules. Master’s-level therapists cannot be the attending provider.

That full-license list is separate from Chapter 2’s conditional student policy. A student arrangement must satisfy both the general delegation rules and the specific mental-health service restrictions; a supervisor’s eligibility does not make every service or supervisee payable.

Can an LICSW, LMFT or LMHC bill the initial evaluation under a supervisor?

No. Chapter 17 expressly excludes mental-health evaluations 90791 and 90792 performed by these master’s-level therapists, even under a clinical psychologist’s or psychiatrist’s direct supervision. They may provide treatment after evaluation by a psychiatrist, psychiatric APRN or psychologist. For this L&I benefit, master’s-level therapists provide psychotherapy without an evaluation-and-management component. This is a payment restriction, not a statement that their professional license forbids diagnosis in every setting.

Whose identifier goes on the student bill?

Chapter 2’s student rule says students do not bill L&I themselves: their supervisors bill using their own L&I provider account numbers. All chart notes and documentation require the supervisor’s co-signature showing review and approval. The supervisor remains responsible for treatment and treatment plans.

An L&I provider account number is not the same thing as an NPI. Chapter 2 separately describes NPI registration, State Fund account-number use and self-insured billing. The student paragraph does not provide a universal rendering-NPI substitution instruction for every electronic claim. Preserve the distinction rather than converting the account-number rule into an unsupported claim-field recipe.

What authorization and documentation are required?

Outpatient mental-health services require prior authorization, except the initial visit to open a mental-health-only claim; the psychotherapy section requires authorization for treatment. A student arrangement does not waive this. Treatment must address conditions caused or aggravated by the industrial condition, with measurable functional goals. Mental-health documentation goes to the insurer and attending provider, using the required clinical notes and employment/restriction information. Student documentation also needs the supervisor’s co-signature.

Behavioral Health Interventions (BHI), activity coaching and psychological-test technicians have separate rules. For example, Chapter 17’s BHI section expressly points to the student policy, while testing has its own technician and supervision requirements. Neither is a blanket substitute for psychotherapy eligibility.

Sources and currentness

This guide uses L&I’s currently linked payment policies effective July 1, 2026: Chapter 2, especially pages 2-8–2-13; Chapter 17, especially pages 17-6–17-13 and 17-40–17-42; and WAC 296-21-270. The current updates-and-corrections index was checked for superseding changes. Match the actual clinician and service to these requirements; neither an associate license nor a supervisor’s enrollment alone establishes payment.
