Getting a provider in-network in Washington means three separate enrollments that share one file: Medicare through PECOS and Noridian Healthcare Solutions, Apple Health through ProviderOne, and each commercial plan you want, starting with Premera Blue Cross and Regence BlueShield. Provider Enrollment Credentialing Services handles all three for physicians, nurse practitioners, physician assistants, therapists and group practices across the state, at flat per-service prices, followed up regularly until approval.
Typical timing from a complete application: Medicare 45 to 90 days, Apple Health 60 to 120 days, and commercial plans held to the 90-day credentialing decision deadline that Washington law sets (RCW 48.43.750; details below).

Medicare in Washington
Medicare enrollment is national, but the review happens at the Medicare Administrative Contractor for your jurisdiction. For Washington that is Noridian Healthcare Solutions, jurisdiction JF. Individual practitioners file the CMS-855I in PECOS, groups file the 855B and each clinician reassigns benefits with the 855R, and EFT is set up with the 588. Noridian Healthcare Solutions typically processes a clean application in 45 to 90 days and Medicare allows billing back to the effective date, which is why Medicare goes first: it is the one enrollment that pays for the waiting time. Development letters give you 30 days to respond, and an unanswered letter is the most common reason a Washington application is returned.
Apple Health
Apple Health is administered by the Washington State Health Care Authority. Provider enrollment is filed through ProviderOne. Every enrollment is screened at a federal risk level: limited-risk types such as physicians, nurse practitioners and most therapists get a license and database check; moderate and high-risk types, which include many agencies and suppliers, add a site visit and in some cases fingerprint-based background checks for owners. Most Washington Medicaid members are in managed-care plans, and each MCO credentials and contracts separately after the state enrollment is active, so a practice that wants Medicaid patients usually needs the state enrollment plus two to four MCO applications. Revalidation is required at least every five years.

Nurse practitioners: Washington is a full practice state. See NP credentialing in Washington.
Therapists: Washington's PSYPACT, Counseling Compact and Social Work Compact status, and what each means for LPC, LCSW and LMFT enrollment, are in therapist credentialing in Washington.
Commercial Plans in Washington
The Blue Cross Blue Shield licensee for Washington is Premera Blue Cross and Regence BlueShield, and for most practices it is the first commercial application because it carries the largest share of employer-sponsored members in the state. Aetna, Cigna, UnitedHealthcare and Humana operate statewide and take applications through Availity or their own provider portals, verifying credentials against your CAQH (DataSpring) profile. Behavioral health clinicians apply to the plans' behavioral arms, Optum Behavioral Health, Evernorth and Carelon, rather than the medical networks. Every commercial application is $200 per provider and runs 90 to 120 days; the contract's effective date is set when the plan countersigns, not when you submit.
Washington Credentialing Law
Washington law gives commercial plans 90 days to decide, counted from a complete application, with the carrier's average required to stay under 60 days (RCW 48.43.750).
Application form: Carriers must use ProviderSource by OneHealthPort, the state-selected credentialing database. (RCW 48.43.750)
Payment while you wait: A provider added to an existing contract is paid from submission of the completed application. (Laws 2020 (EHB 1552))

The Order That Works
- NPI, Tax ID and, for groups, the Type 2 NPI and group W-9, all matching your legal name exactly.
- CAQH (DataSpring) profile built and attested, with the Washington license, DEA, malpractice certificate and five-year work history uploaded.
- Medicare through PECOS and Noridian Healthcare Solutions, then Apple Health through ProviderOne.
- Premera Blue Cross and Regence BlueShield and the national plans in the same week, so the 90 to 120 day clocks run in parallel.
- Regular follow-up with every payer, effective dates recorded, and the maintenance calendar started for re-attestations, license expirations and revalidation.

Questions Washington Practices Ask
How long does credentialing take in Washington?
Washington law gives commercial plans 90 days to make a credentialing decision, counted from a complete application, with the carrier's average required to stay under 60 days (RCW 48.43.750). Contracting and loading you into the plan's systems can add time after the decision. Medicare through Noridian Healthcare Solutions typically takes 45 to 90 days and allows retroactive billing to the effective date. Apple Health enrollment through ProviderOne typically runs 60 to 120 days depending on risk level and whether a site visit or fingerprinting applies. Commercial plans such as Premera Blue Cross and Regence BlueShield run 90 to 120 days and set the effective date at contract countersignature.
Do I need to enroll in Apple Health before joining its managed-care plans?
Yes. Washington delivers most Medicaid benefits through managed-care organizations, and federal rules require every MCO network provider to be enrolled with the state program first. The state enrollment through ProviderOne comes first; each MCO application follows as its own commercial-style credentialing.
Which Medicare contractor handles Washington?
Noridian Healthcare Solutions is the Medicare Administrative Contractor for jurisdiction JF, which includes Washington. Applications are filed in PECOS and reviewed by Noridian Healthcare Solutions; development requests and approval letters come from them.
