The Washington Provider Account Application is a comprehensive form used by providers in the state of Washington to apply for and maintain a provider account with the Department of Social and Health Services (DSS). This form is used by health care providers, such as hospitals, clinics, and laboratories, to register with the state and obtain reimbursement for services provided to DSS clients. The application includes sections on business information, ownership information, and financial information. There are two types of Washington Provider Account Applications: online and paper. The online application is available through the DSS website, and the paper application can be printed and mailed to the DSS.
