Clinical Classification Guidelines
Medical Intelligence & Overview
Enlarged lymph nodes, medically known as lymphadenopathy, refer to swollen or enlarged lymph nodes that can occur anywhere in the body. The ICD-10 code R59.9 is used when the cause of the lymph node enlargement is not specifically identified. Lymph nodes are an essential part of the immune system, helping the body fight infections and filter out harmful substances. While swollen lymph nodes are often a sign of an underlying health issue, their location, size, and associated symptoms can provide important clues to healthcare providers seeking diagnosis and management.
