Other nonspecific lymphadenitis

This code represents inflammation of the lymph nodes that is not specified as acute, chronic, or due to a particular infectious agent or systemic disease. It indicates a general inflammatory response within the lymphatic system without further diagnostic refinement.

Use this code when documentation indicates lymphadenitis but lacks specificity regarding its etiology, duration, or precise anatomical location beyond a general region. It is appropriate when the physician has diagnosed lymphadenitis but the underlying cause remains undetermined or is not explicitly documented.

• Avoid using this code if a more specific type of lymphadenitis (e.g., acute, chronic, suppurative, or due to a specific infection) is documented.
• Query the provider for more specific documentation if possible, especially regarding the cause or chronicity.
• This code is often used as a provisional diagnosis or when diagnostic workup is incomplete.
