Starting a solo therapy practice in Washington: license, entity, and panels
Summary
Opening a solo therapy practice in Washington means clearing the Department of Health's Licensed Mental Health Counselor tier, distinct from its lower Agency Affiliated Counselor registration, then picking a business entity, working out Washington Medicaid enrollment under integrated managed care, and setting telehealth and consent policies for clients physically located in the state. Verify current DOH requirements before treating any step here as settled.

Registered or licensed: Washington's two tiers, and why it matters for solo practice
Washington doesn't route mental-health credentialing through a freestanding counseling board — the Department of Health issues the credential directly, and it does so across two distinct tiers: an Agency Affiliated Counselor registration for those practicing under an agency's supervision, and a separate Licensed Mental Health Counselor (LMHC) credential for anyone practicing independently 1Ref 1Washington State Department of Health — Licenses, Permits and Certificates (2026).Washington State Department of Health — Licenses, Permits and Certificates.Washington licensure requirements, applications, fees, renewal rules, and supervision requirements for the Agency Affiliated Counselor and LMHC tiers, and DOH telehealth/consent guidance.. A solo private practice sits squarely in the second tier; the registration alone does not authorize it.
That two-tier design is unusual. Oregon, just south, licenses independent counseling practice through a single LPC credential from its own dedicated board, with no separate lower registration standing in front of it 2Ref 2Oregon Board of Licensed Professional Counselors and Therapists (2026).Oregon Board of Licensed Professional Counselors and Therapists.That Oregon licenses independent practice under a single LPC credential issued by its own dedicated board without a separate lower-tier registration, used here only as a neighboring-state contrast to Washington's two-tier DOH structure.. A clinician arriving in Washington from a single-tier state like Oregon should not assume a credential that authorized independent practice there does the same thing here without confirming which of Washington's two tiers it actually maps to.
Getting from registration to independent LMHC status
Reaching LMHC status in Washington means clearing a defined stretch of supervised practice first, and DOH sets the specifics — required hours, what makes a supervisor qualified, and which exam clears the way to independent licensure 1Ref 1Washington State Department of Health — Licenses, Permits and Certificates (2026).Washington State Department of Health — Licenses, Permits and Certificates.Washington licensure requirements, applications, fees, renewal rules, and supervision requirements for the Agency Affiliated Counselor and LMHC tiers, and DOH telehealth/consent guidance.. None of that is assumed portable; hours logged under a supervisor whose credentials Washington doesn't separately recognize can end up not counting.
A jurisprudence exam and an application queue that behaves roughly the same way from state to state are covered on the national pillar rather than here — the practice-formation and state-licensure basics apply to Washington the same as anywhere, and this page exists to cover what doesn't: the state's own two-tier structure, its Medicaid system, and its telehealth rules.
Choosing between a PLLC and a professional service corporation
Two entity types built for licensed occupations are available to a Washington LMHC setting up solo: a professional limited liability company and a professional service corporation. Either separates the owner's personal assets from claims against the practice in a way a bare sole proprietorship does not, and Washington's business-entity statute treats both as valid vehicles for a licensed clinician's practice.
The right pick turns on tax treatment and on whether the practice plans to stay a one-person operation or eventually take on associate clinicians — that's a conversation for a CPA or business attorney who actually knows Washington's rules, not a decision to make by copying a colleague's paperwork.
Medicaid behavioral health inside Washington's integrated managed care
Washington finished rolling out integrated managed care statewide, which means Medicaid no longer separates behavioral-health financing into its own carve-out — physical and behavioral health claims run through the same regional managed-care contracts. A solo LMHC enrolling with Washington Medicaid should confirm which regional managed-care organizations cover the practice's service area directly with the state's Health Care Authority, since assuming a standalone behavioral-health enrollment track still exists is likely to waste time chasing a process the state already folded away.
Corporate-practice-of-medicine restrictions on non-clinician control of clinical decisions apply here too, though — as in most states — they weigh far more heavily on prescribing arrangements than on a master's-level solo counseling practice; the actual line depends on Washington's statute and the specifics of a given ownership structure, which is squarely a question for counsel rather than something this page can settle in general terms. Commercial credentialing otherwise runs through the standard CAQH-attestation process used nationally.
Telehealth rules for a Washington solo caseload
Washington sets its own telehealth and informed-consent rules for behavioral health independently of whatever federal flexibilities are in effect at a given moment, so pull current requirements — including any allowance for audio-only sessions — straight from DOH rather than relying on training-era knowledge or a rule that applied in a previous state 1Ref 1Washington State Department of Health — Licenses, Permits and Certificates (2026).Washington State Department of Health — Licenses, Permits and Certificates.Washington licensure requirements, applications, fees, renewal rules, and supervision requirements for the Agency Affiliated Counselor and LMHC tiers, and DOH telehealth/consent guidance.. Whatever guidance an intake policy is built around, note when it was pulled, since this is one of the faster-moving corners of practice-start compliance.
What actually governs a given telehealth session is the state the client is physically sitting in, not the location of the clinician's office. A Washington LMHC building a caseload that might cross state lines should check current interstate-compact participation with DOH before treating anyone located outside Washington.
Professional will, and stacking Washington against nearby states
Payer credentialing works the same nationally once licensure, entity setup, and a Medicaid decision are behind a practice, so that process lives on the linked national pillar rather than being repeated here — just make sure any credentialing application names the Department of Health, not a counseling-specific board that doesn't exist in Washington, as the issuing authority.
A solo practice with no one designated to step in is a real gap: build a professional will — a written, standing agreement with a licensed colleague to notify current clients, secure records, and wind the practice down if its owner is suddenly unable to work — before a crisis makes the decision urgently, not after. No Washington statute requires this, but it is close to universal advice from malpractice carriers and ethics boards alike. Clinicians weighing multiple states can set Washington's two-tier registration model against the guides for starting a therapy practice in Michigan, starting a therapy practice in Minnesota, starting a therapy practice in Mississippi, starting a therapy practice in Missouri, starting a therapy practice in Montana, and starting a therapy practice in Nebraska.
