Nonspecific lymphadenitis, unspecified

This code signifies inflammation of a lymph node or nodes without a specified cause or location. It indicates a general, unlocalized inflammatory response within the lymphatic system.

This code is appropriate when documentation indicates lymphadenitis but lacks specific details regarding the causative agent, the affected anatomical site, or the type of inflammation (e.g., acute, chronic, suppurative). It is used when the provider's assessment is limited to "lymphadenitis, unspecified."

• Avoid using this code if a more specific type or location of lymphadenitis is documented (e.g., acute mesenteric lymphadenitis, cervical lymphadenitis).
• Query the provider for additional specificity if possible, as this code offers minimal clinical detail for reimbursement and data analysis.
• Do not use this code for enlarged lymph nodes without documented inflammation; R59.- (Enlarged lymph nodes) would be more appropriate.
