As a part-time utilization review nurse, your job is to review the medical necessity of a procedure and ensure that all services offered to a patient meet regulatory compliance requirements. Utilization review nurses often focus on reducing costs while maintaining or improving the quality of patient care. You then relay this information to other reviewers and third-party payers. Many utilization review nurses help answer questions from insurance companies, apply critical thinking and good judgment to unusual cases, ensure accurate and appropriate documentation of everything that occurs, and conduct additional research as needed for a given case. Part-time utilization review nurses usually work in areas that have lower patient volume.
