Washington Medical Payment Guidance is a set of regulations and guidelines provided by the Washington State Health Care Authority (HCA) to ensure that the payments made to health care providers are made in a fair and equitable manner. It is designed to protect health care providers from unfair practices by insurers, and to ensure that consumers receive the medical care they need. Washington Medical Payment Guidance covers all types of medical services, including primary care, specialty care, hospital stays, and inpatient and outpatient services. The guidance includes information on billing and payment practices, provider participation in payment plans, and provider reimbursement. There are three main types of Washington Medical Payment Guidance: Fee-For-Service (FFS) Guidance, Managed Care Organizations (CMOS) Guidance, and Specialty Care Guidance. Fee-For-Service (FFS) Guidance is designed to ensure that health care providers are paid fairly for services rendered, regardless of the patient’s insurance coverage. Managed Care Organizations (CMOS) Guidance is designed to ensure that health care providers are reimbursed appropriately when they participate in a managed care plan. Specialty Care Guidance is designed to ensure that health care providers are reimbursed appropriately when they provide specialty services.
