Washington Mental Health Fee Schedule and Billing Guidelines are documents that provide information regarding reimbursements to mental health providers for services rendered to Medicaid eligible individuals. They are applicable to all Medicaid-enrolled mental health providers in the state of Washington. The Fee Schedule and Billing Guidelines outline the procedures for submitting claims, rules for reimbursement, and established payment rates for services. The guidelines are divided into two types: the Washington State Health Care Authority (HCA) Fee Schedule and the Washington State Department of Social and Health Services (DSS) Fee Schedule. The HCA Fee Schedule is applicable to all mental health providers in the state who are enrolled in Medicaid and provides information on reimbursements for all Medicaid-covered services, including those provided in an inpatient or outpatient hospital setting. The DSS Fee Schedule is applicable to mental health providers who are enrolled in the Apple Health (Medicaid) program and provides information on reimbursements for Apple Health-covered services, including those provided in an inpatient or outpatient hospital setting. This fee schedule also includes rules and procedures for submitting claims and additional payment rates for services rendered to Apple Health beneficiaries. Both the HCA and DSS Fee Schedules and Billing Guidelines are updated regularly to reflect any changes in reimbursement rates and applicable regulations.
