Washington Behavioral Health Credentialing: Apple Health and Commercial Payers

Washington is the best state in the country to get commercially credentialed in, and state law is the reason. Carriers have 90 days to decide, they have to average 60, and once you’re approved they have to pay you back for the wait. Apple Health does the exact opposite and pays nothing while your enrollment is pending. That gap is why sequencing here is worth real money.

The Washington rule worth knowing

Commercial pays you back. Medicaid pays you nothing. Don’t blur them.

RCW 48.43.750 makes carriers accept credentialing only through the state-designated database, decide within 90 days of a complete application, and keep their determinations averaging no more than 60 days. RCW 48.43.757 then makes them pay for the wait.

Read the back-pay rule carefully, because the date it runs from changes with your situation. Under a new contract, reimbursement goes back to the contract effective date if credentialing runs past it. When you’re added to an existing approved contract, it goes back to the date the completed credentialing application was submitted, at the contracted rate. It doesn’t apply if the application is denied or no contract is executed, and it doesn’t turn a non-covered service into a covered one.

Now the inverse, stated plainly. The Health Care Authority says it does not pay for services delivered while a Core Provider Agreement application is still pending, whether the agreement is later approved or denied. So in Washington the commercial half of your revenue is protected during the wait and the Apple Health half is not, and that single asymmetry is what decides the order we file things in.

One more thing that costs people weeks. CAQH became Washington’s designated credentialing database on January 1, 2024, replacing OneHealthPort’s ProviderSource, which was disabled on December 31, 2023. At least one national carrier’s own public credentialing page still lists the retired route next to CAQH. Following a payer’s own written instructions can send you down a dead path, which is a decent argument for checking rather than trusting.

Credentialed›contracted›loaded›connected›payable

In Washington the second box is usually the slower one. Premera and Regence both credential first and contract second, and a Premera agreement isn’t effective until Premera countersigns it. Plan your go-live off the countersigned effective date, not off the credentialing approval email.

Two tracks

Apple Health integrated behavioral health in 2020. Commercial takes two Blues.

Washington runs one of the cleaner Medicaid setups in the country. The complication is on the commercial side, and it’s a license-map problem rather than a paperwork problem.

Washington Apple Health

Pick the right enrollment type, then contract by region.

Enrollment runs entirely through ProviderOne, and the first real decision is which of three enrollment types fits how you actually bill. Getting that wrong is easy and expensive.

Three doorsBilling is a solo practice or group that bills the Health Care Authority directly: Core Provider Agreement (form 09-015), Debarment Statement (09-016) and a W-9. Servicing is a clinician practicing under a group, with no extra signed agreement, but the group above you must already be enrolled as a billing provider or your application is denied. Nonbilling covers a clinician who only sees Apple Health members through a managed care plan, or who enrolls solely to order, refer or prescribe.
Behavioral health is already inside the planIntegrated Managed Care went statewide on January 1, 2020, so one plan is responsible for a member’s physical health, mental health and substance use benefit. There’s no separate behavioral health payer to chase for a managed care member.
Two structures people confuse with a carve-outBHSO plans cover behavioral health for Apple Health clients who aren’t eligible for full managed care enrollment: dual-eligible, medically needy, or spenddown-met. They’re offered by the same five health plans, so your plan contracts generally reach those members too. BH-ASOs are regional, block-grant funded, and run the 24/7 crisis line, mobile crisis outreach and Involuntary Treatment Act work. A BH-ASO is not the payer for routine outpatient behavioral health for a managed care member.
The plans, and the one that isn’t statewide

Commercial

Two Blue licensees, inside one state.

Premera holds the Blue Cross license for all of Washington except Clark County, plus Alaska. Regence BlueShield holds the Blue Shield license in select Washington counties. Clark County, the Vancouver side of the Portland metro, sits with Regence BlueCross BlueShield of Oregon.

That’s a shared service area, not fragmentationReaching the full in-state Blue population usually takes both Premera and Regence. That’s two licensees inside one state, which is a different problem from needing a contract per state. One Blue contract still reaches Blue members in other states through BlueCard when you’re licensed there.
An open-door law worth knowingRCW 48.43.045 requires health plans to permit every category of health care provider to deliver covered services in the essential health benefits benchmark, subject to the plan’s utilization review and cost containment standards. Optum’s own Washington page cites it and says it accepts applications in compliance, which is part of why Washington panels run more open to behavioral health applicants than the states next door.
Behavioral health doorsUnitedHealthcare routes it to Optum through Provider Express. Cigna routes it to Evernorth. Aetna keeps it in-house on a separate behavioral request form. Premera, Regence and Kaiser Permanente Washington all handle behavioral health inside the plan.
Seeing patients in other statesAetna, Cigna and UnitedHealthcare are already national, so one contract each. The gate is a license where the patient is sitting. Medicaid is the genuine exception and Apple Health doesn’t travel.

Washington commercial payers

Who you’ll apply to, and which door behavioral health goes through.

The 90-day statutory ceiling and the 60-day average are the carrier’s obligation. What follows is what each carrier publishes about its own practice, which is a different thing, so we track it rather than promise it.

Premera Blue Cross

Blue Cross for all of Washington except Clark County
  • Credentialing: Premera says most providers finish in 60 days or less, and its behavioral health page says behavioral credentialing typically runs under two weeks
  • Contracting is the slower half: 45 to 60 business days to review, sign and return documents, and the agreement isn’t effective until Premera countersigns
  • Your clock too: you get 30 days to return signed documents before the request is closed
  • Watch your CAQH email: Premera routes the signed application through Certify, which emails the address on your CAQH profile. Keep the attestation inside 90 days
  • Behavioral health: managed in-plan, no carve-out vendor

Regence BlueShield

Blue Shield in select Washington counties
  • Real backlog, published: Regence posts a live application-status marker. At this verification it was processing applications submitted on or before April 24, 2026, roughly a two to three month working queue
  • Since June 15, 2026: Regence uses the CAQH Provider Data Portal for both initial credentialing and recredentialing, and asks you to notify its credentialing department through the CAQH profile notification form once you’ve re-attested
  • The single most common stall: Regence requires a copy of your IRS CP 575 or 147C letter. Missing it stops the file
  • Don’t let a contract lapse: more than 30 days without an active contract, including having no active practice location, forces a full new initial application

UnitedHealthcare

Behavioral health goes through Optum
  • The strongest published signal in the state: Optum’s Washington page recognizes Washington as an any-willing-provider state and lists MDs, DOs, PAs and RNs with prescriptive authority as actively sought in all Washington counties
  • Also wanted: telemental health providers and prescribers offering medication-assisted treatment for addiction
  • Usually: 60 to 120 days from a complete application. Start inside Provider Express under Join Our Network, not the medical site

Separate door: Optum Behavioral Health

Kaiser Permanente Washington

Not the closed system Kaiser is in Oregon
  • Contracts with community providers across seventeen counties including King, Pierce, Snohomish, Spokane, Thurston and Whatcom
  • The opening: unsolicited applications for new contracts are generally closed, but Kaiser says it is accepting applications for new Mental Health and Wellness contracts in select Washington counties. Worth checking rather than assuming closed
  • Hard limit: it won’t accept applications from providers located outside its Washington and Idaho service areas, even for telehealth
  • Form: credentialing runs on the Washington Practitioner Application submitted through CAQH. No published turnaround, because the gate is network need rather than a queue

Cigna Healthcare

Behavioral health goes through Evernorth
  • Usually: up to about 90 days, with re-attestation every 120 days
  • Washington-specific caution: Cigna’s public credentialing page still lists a OneHealthPort or Medversant option next to CAQH. That route is retired. In Washington, use CAQH
  • Aetna, for comparison: a request for participation, an answer on network need in about 45 days, then CAQH-sourced credentialing. Behavioral clinicians use Aetna’s separate behavioral form

Separate door: Evernorth Behavioral Health

First Choice Health

The Washington network people forget until a claim arrives
  • Usually: First Choice asks you to allow a minimum of 60 days, then notifies you with a participation effective date
  • Why it earns its effort: a provider-sponsored PPO widely rented by self-funded Washington employers, union trusts and third-party administrators, so a card that says something else entirely may reach you through First Choice
  • Stated minimums: malpractice of $1,000,000 per incident and $3,000,000 aggregate

Community Health Plan of Washington is worth knowing as more than a Medicaid plan: alongside Apple Health it runs Medicare Advantage, a dual-eligible special needs plan and Individual and Family Cascade Select plans, so one relationship can touch several lines. Premera is direct that Washington-state providers with an approved specialty qualify for contracts and that out-of-state contracts are limited, so this is a contract you want based on where you practice. Medicare and Apple Health work are scoped separately from a commercial package.

Carry a plan we didn’t list? Add it.

The Uniform Medical Plan is the one most people miss. UMP is the self-insured plan for Washington public employees and school employees, offered through the Health Care Authority’s PEBB and SEBB programs and administered by Regence BlueShield. Providers reach UMP members through their Regence BlueShield contract rather than a separate UMP contract. That’s a strong practical argument for holding Regence even if your commercial mix looks Premera-heavy, and it’s the kind of thing that decides a contract order.

Union and Taft-Hartley health and welfare trusts, including the Puget Sound building trades funds, are usually reached by joining a rented commercial network rather than by contracting with the fund. In Washington that rented network is frequently First Choice Health. Give us the plan name and we confirm the actual route. You don’t need to learn the plumbing.

What we need from you

Send these once and we can start.

You give us this in one intake. Then we fill out the applications. No passwords, no patient information, and nothing gets submitted until you’ve read it and signed.

  • Your individual NPIPlus the Type 2 if you bill under a group. Washington plans check both are registered and active with the Health Care Authority before they’ll load a Medicaid contract.
  • Active Washington license and DEAPremera and Regence both verify these as part of the credentialing file.
  • CAQH attested and authorizedNot optional housekeeping here. CAQH is the state-designated credentialing database, so an unattested profile blocks every commercial application at once.
  • Your IRS CP 575 or 147C letterRegence requires it to complete a credentialing application and Premera asks for the EIN documentation on new contracts. Missing it is the most common Washington stall. A 147C can be requested from the IRS if the original is gone.
  • Delegated ProviderOne accessSo we can complete your Apple Health enrollment and each plan application without password sharing. Confirm the mailing address on file too, because that’s where revalidation notices go.
  • Malpractice certificateNaming you by name, or a carrier-produced roster face sheet. First Choice states $1M per incident and $3M aggregate.
  • Five years of work historyMonth and year, with any gap over six months explained. Premera and First Choice both reject files for this specific reason.
  • Entity name, EIN and W-9One per tax ID you bill under. The W-9 is also a required document in the ProviderOne billing-provider application.

Washington licenses the agency rather than the clinician, through a Department of Health Behavioral Health Agency license certified by service category, and licensing moved from DSHS to the Department of Health in 2018 so older guides point at the wrong agency. This one deserves a careful look rather than a quick reassurance: Washington’s outpatient certification scope expressly names psychiatric medication management, and we found no written private-practice exemption in the agency rules, only tribal and hospital exemptions plus a discretionary waiver on written request. What generally keeps a solo prescriber outside it is being an individual rather than an agency, which is a structural read and not a citation. We ask about your service mix and structure at intake and flag it early. We don’t tell you whether you need a license, we don’t publish the rules, and we don’t file it for you. A group practice in particular should get a real determination from the Department of Health and its own counsel.

Rather hand the whole thing off? Credentialing and payer enrollment is what we do, in Washington and in the other 49. Physicians and outpatient medical groups, psychiatrists included, start on the physician credentialing page.

How it works

You answer once. We do the paperwork.

You can buy online without booking a meeting. Nobody has to sell you anything first.

Buy the package

Published price and scope. No call needed.

One intake

Short and guided. It asks more only where your answers call for it.

We prepare everything

Your ProviderOne enrollment, each Apple Health plan application and every commercial application, filled out from what you told us.

You review and sign

Read it, change anything, sign. Nothing goes out until you say so.

We submit and track

You see what’s done, what’s waiting on a payer, and when you can bill.

What we commit to

Tracking is included. Every package comes with Command Suite access, so you can see where each payer application stands, what we are working on, what is waiting on a payer, and what we still need from you. You are not left guessing between the purchase and the finish.

If something we delivered does not work the way we said it would, we fix it at no charge for 30 days after delivery, including one stabilization review. That covers our own work. A new request, another payer or provider, or a change of scope is quoted separately.

Built to keep working after we are done. Everything we set up is built for the practice you are growing into, not only the one you have today. When the engagement ends you own the accounts, the documentation, and the systems, and they keep running without us.

Questions we get

Washington credentialing questions

Does Washington really make carriers pay me for the wait?
On the commercial side, yes. RCW 48.43.757 requires a carrier credentialing a new provider under a new contract to reimburse covered services retroactively to the contract effective date if credentialing runs past it. When you’re added to an existing approved contract, it runs back to the date your completed credentialing application was submitted, at the contracted rate. It doesn’t apply if the application is denied or no contract is executed. It’s a real reason to get a complete application in early rather than waiting for a start date.
Does the same rule cover Apple Health?
No, and this is the one place people get badly caught. The Health Care Authority states that it does not pay for services delivered while a Core Provider Agreement application is still pending, whether the agreement is later approved or denied. So the commercial half of your revenue is protected during the wait and the Medicaid half is not. That asymmetry is exactly why we sequence Apple Health first for a practice that needs Medicaid volume.
How long can a carrier take?
RCW 48.43.750 gives them 90 days from a complete application and requires their determinations to average no more than 60. It also requires them to accept credentialing through the state-designated electronic database and bars them from demanding another format. That’s the carrier’s legal obligation, not a prediction about your file, and none of it starts until the application is genuinely complete.
CAQH or ProviderSource?
CAQH, since January 1, 2024. ProviderSource, run through OneHealthPort, was disabled on December 31, 2023. Any Washington instruction pointing at ProviderSource or Medversant is stale, and at least one national carrier’s own public credentialing page still lists the retired route. Following a payer’s written instructions can send you somewhere that no longer exists, which is why we check the door before anyone files.
Do I need both Premera and Regence?
Usually. Premera holds Blue Cross for all of Washington except Clark County, plus Alaska. Regence BlueShield holds Blue Shield in select counties. Clark County, on the Vancouver side of the Portland metro, sits with Regence BlueCross BlueShield of Oregon. That’s a shared Blue service area inside one state, which is a different thing from needing a contract per state. There’s also a practical reason to hold Regence even if your mix looks Premera-heavy: Regence administers the Uniform Medical Plan for state and school employees.
Does Kaiser credential outside providers here?
Sometimes, and the Oregon answer doesn’t apply. Kaiser Permanente Washington contracts with community providers across seventeen counties. Unsolicited applications for new contracts are generally closed, but Kaiser says it is accepting applications for new Mental Health and Wellness contracts in select counties, which is a genuine opening for a prescriber. It won’t take applications from providers located outside its Washington and Idaho service areas, even for telehealth, and an unsolicited request only gets a reply if it meets an existing network need.
Which Apple Health enrollment type do I pick?
Billing if you bill the Health Care Authority directly, which means a Core Provider Agreement, a Debarment Statement and a W-9. Servicing if you practice under a group, which needs no extra signed agreement but does require the group above you to already hold its own Core Provider Agreement, or your application is denied. Nonbilling if you only see Apple Health members through a managed care plan, or you’re enrolling solely to order, refer or prescribe. The online billing application runs up to 18 steps and issues a 14-digit application ID after step one, and you need that ID to get back in.
Do you need my CAQH password?
No, and we won’t ask. We’re added as an authorized practice manager, which lets us keep your practice data current and authorize payers. You complete and attest your own profile and you sign your own paper applications. Keep the attestation fresh: Premera wants it inside 90 days, and because CAQH is the designated database here, a lapse blocks everything at once.
