Enlarged lymph nodes, unspecified

This code signifies the presence of abnormally enlarged lymph nodes without further specification of their location or underlying cause. It indicates a generalized or localized lymphadenopathy where the etiology remains undetermined at the time of coding.

Use this code when documentation indicates "enlarged lymph nodes," "lymphadenopathy," or "swollen glands" without any additional details regarding the specific anatomical site (e.g., cervical, axillary) or the suspected or confirmed cause. This is a placeholder code for initial assessment or when a definitive diagnosis is pending.

• Avoid using this code if the specific location of the enlarged lymph nodes is documented (e.g., R59.0 for localized, R59.1 for generalized).
• Always strive for a more specific diagnosis if available, as this code represents an unspecified condition.
• Do not use this code if the underlying cause of the lymphadenopathy is known and documented (e.g., infection, malignancy). Code the underlying condition instead.
