ACS LION (Leadership in Oncology Navigation)

Professional, non-clinical patient navigation is an evidence-based intervention that improves cancer outcomes from screening through survivorship. The American Cancer Society Leadership in Oncology Navigation (ACS LION) is a standardized training and credentialing program that helps navigators deliver this essential support to individuals, caregivers, and families experiencing cancer. The program meets the Centers for Medicare & Medicaid Services (CMS) training requirements for “Principal Illness Navigation” reimbursement and is aligned to professional oncology navigation (PONT) standards.
