Medical Bill Disputes in Washington: Your Rights and Options
Washington State has banned medical debt from consumer credit reports since 2021 — years before the federal rule — and it has one of the most accessible surprise billing arbitration systems in the country. Yet a study found that Washington providers still send over 30% of low-income patients to collections without screening them for charity care first.

Key Washington Consumer Protections
Washington’s Surprise Billing Law (SB 5526, 2019)
Washington enacted significant surprise billing protections in 2019. Under this law:
- Patients who receive emergency care or covered non-emergency care at in-network facilities cannot be balance billed by out-of-network providers
- Patients’ cost-sharing cannot exceed what they would owe for in-network services
- A dispute resolution process exists between insurers and providers
Federal No Surprises Act (2022)
The federal law provides additional protections, particularly for self-insured ERISA employer plans not covered by Washington state law. Washington-regulated plans follow whichever rule provides stronger consumer protection.
Washington’s Charity Care Law (RCW 70.170.060)
Washington has a mandatory charity care law requiring hospitals to provide free or reduced-cost care to patients who qualify based on income. The law requires hospitals to:
- Publicize their charity care policies
- Screen patients at or near the time of service
- Provide charity care to patients with incomes up to a defined threshold (varies by hospital, often 200%–300% of FPL)
- Not discriminate based on immigration status in providing charity care
Washington’s charity care law is one of the most comprehensive in the nation.
Uniform Medical Plan (UMP)
State employees covered by Washington’s Uniform Medical Plan have access to additional dispute processes through the Health Care Authority.

How to Dispute a Medical Bill in Washington
Step 1: Request an itemized bill. Washington providers must provide itemized bills on request. Use our EOB decoder to understand your Explanation of Benefits.
Step 2: Check for errors. Review for upcoding, duplicate charges, phantom services, and balance billing that violates Washington’s surprise billing law. See our billing errors guide.
Step 3: Contact the provider in writing. Specify each disputed charge and cite Washington law (RCW or WAC references) where applicable.
Step 4: File a grievance with your insurer. Washington-regulated plans must have grievance procedures. File in writing and document the response.
Step 5: File with OIC. If unresolved, file a complaint with OIC. The Commissioner’s office actively investigates surprise billing violations and can require corrective action and refunds.
Step 6: External appeal. Washington has an external review process for denied claims through OIC.

Washington’s Medical Debt Credit Reporting Ban
Washington State enacted SHB 1061 in 2021, making it one of the first states in the country to prohibit medical debt from appearing on consumer credit reports. Under Washington law:
- Medical debt cannot be included in a consumer credit report
- Credit bureaus operating in Washington must suppress medical debt tradelines for Washington residents
- This protection applies to all medical debt regardless of amount or age
Washington’s Balance Billing Protection Act (SB 5526, 2019) provides additional protections for state-regulated plans:
- Emergency care providers cannot balance-bill patients for amounts beyond in-network cost-sharing
- Out-of-network providers at in-network facilities must give written notice and obtain consent before billing out-of-network rates for scheduled services
- The OIC maintains a free complaint resolution process that resolves most billing disputes within 45 days
Washington also has a uniquely accessible charity care system: the Charity Care Law (RCW 70.170) requires all Washington licensed hospitals to provide charity care to patients below 100% FPL at no charge, and discounted care to patients up to 200% FPL. Unlike most states, Washington’s charity care standards are set statewide — the same rules apply at every hospital.
