The Washington Provider Payment Account Change Form is an official document used by providers in the state of Washington to change the payment account that is associated with their medical provider services. This form is used to update the banking information for payments made by the Washington State Health Care Authority (HCA) to the provider. There are two types of Washington Provider Payment Account Change Forms: one for Providers and one for Billing Agents. The Provider form is used when the provider wants to change the bank account or routing number to which their payments are deposited. The Billing Agent form is used when a billing agent submits claims on behalf of a provider and wants to change the bank account or routing number to which their payments are deposited. Both forms require the provider to provide the HCA with their new banking information and must be signed and dated by the provider or their authorized representative.
