Washington Medical Billing Rights

Your rights when dealing with medical bills in Washington. These state laws work alongside the federal No Surprises Act to protect you from unfair billing.

✓ Balance billing protection ✓ Surprise billing law ✓ Medical debt protection ✓ Itemized bill right

Prompt Pay: 30 Days

In Washington, insurance companies must process clean claims within 30 days. If your insurer takes longer, you may be entitled to interest or penalties. If your bill shows a payment date far beyond this window, it could indicate a prompt-pay violation.

WA Rev. Code 48.43.530 (clean claims: 30 days electronic, 45 paper)

Balance Billing Protection

Washington law prohibits providers from billing you for the difference between their charge and the insurance-allowed amount for covered services. If you received emergency care or were treated at an in-network facility by an out-of-network provider, you should not receive a surprise "balance bill."

WA HB 1065 (2019), codified at WA Rev. Code 48.49.020-48.49.040

State Surprise Billing Protections

Washington has enacted surprise billing protections that go beyond the federal No Surprises Act. These state-level protections may cover additional situations, provider types, or offer stronger remedies than federal law alone. When state law provides greater protection, it takes precedence over the federal law.

WA HB 1065 (2019), codified at WA Rev. Code 48.49.020-48.49.040

Right to an Itemized Bill

Under Washington law, you have the right to request a detailed, itemized bill from your healthcare provider. This bill must list each service, procedure code (CPT/HCPCS), and individual charge. An itemized bill is essential for spotting errors — it's the first thing you should request.

WA Rev. Code 70.41.250

Medical Debt Protection

Prohibits wage garnishment for medical debt below certain thresholds; hospitals must offer charity care screening

WA Rev. Code 70.170.060; WA HB 1616 (2022)

Statute of limitations on medical debt in Washington: approximately 6 years. After this period, creditors generally cannot sue to collect the debt. Making a payment or acknowledging the debt may restart this clock.

Federal protections also apply. The No Surprises Act (effective January 1, 2022) protects all Washington residents from surprise balance bills for emergency services and from out-of-network providers at in-network facilities. You also have the right to a Good Faith Estimate for scheduled services if you are uninsured or self-pay. These federal protections apply regardless of state law.
