Washington Provider Payment Account Change Form is a document used to update and maintain payment information for providers in the Washington State Health Care Authority (HCA). This form is used to update the payment account information in the HCA's provider payment system. It enables providers to update their banking information, change the payment method (e.g. direct deposit or check), or make other changes to their payment account information. There are two types of Washington Provider Payment Account Change Form: one for providers registered with the HCA and one for providers not registered with the HCA. Both forms must be filled out and submitted electronically to the HCA in order to make changes to the provider's payment account information.
