Medical Billing Built for Washington Healthcare Providers
Washington expanded Medicaid in January 2014, among the earliest states to do so, and delivers Apple Health, its Medicaid program, through five managed care organizations: Amerigroup Washington, Community Health Plan of Washington, Coordinated Care of Washington, and Molina Healthcare of Washington statewide, plus UnitedHealthcare Community Plan in the western half of the state only — a geographic split that matters when confirming which plan actually covers a given patient. Washington also runs one of only four monopolistic workers' compensation systems in the country (alongside Ohio, Wyoming, and North Dakota): nearly all employers must carry workers' comp exclusively through the state's Department of Labor & Industries (L&I) rather than a private carrier, so work-injury claims follow L&I's own fee schedule and billing rules instead of a commercial insurer's. On the commercial side, Premera Blue Cross and Regence BlueShield — both part of the Cambia Health family — are the state's dominant Blue-branded payers, alongside Kaiser Permanente Washington.
Whether you're in Seattle, Spokane, Tacoma or anywhere else in Washington — ZenoMedix RCM provides the same certified billing expertise with deep knowledge of local payer rules and Washington Medicaid requirements.

Washington Billing FAQ
Yes, significantly. Washington is one of only four monopolistic workers' comp states — employers must carry coverage almost exclusively through the state's own Department of Labor & Industries (L&I) fund rather than a private insurer. We bill occupational claims against L&I's fee schedule and billing rules directly, not a commercial workers' comp carrier.
Not statewide — UnitedHealthcare Community Plan is only available in the western half of Washington under Apple Health.
