Abnormal immunolog findings in specimens from resp org/thrx

This code signifies the presence of unusual or unexpected results from immunological tests performed on samples obtained from the respiratory system or thoracic cavity. These findings suggest an underlying immune system involvement related to respiratory or intrathoracic pathology, but do not specify a definitive diagnosis. It indicates an abnormal immune response or component detected in respiratory secretions, lung tissue, pleural fluid, or other thoracic specimens.

Use this code when laboratory reports indicate abnormal immunological markers (e.g., elevated IgE, autoantibodies, specific cytokines) in respiratory or thoracic specimens without a confirmed diagnosis of an autoimmune, allergic, or infectious disease. Documentation should clearly state "abnormal immunological findings" or similar language from a pathologist or laboratory report, specifically linked to respiratory or thoracic samples.

• This code is for abnormal findings and should not be used as a primary diagnosis when a definitive condition (e.g., asthma, sarcoidosis, autoimmune lung disease) has been established.
• Always sequence this code after the definitive diagnosis if one is known and the abnormal finding is a manifestation of that condition.
• Ensure the documentation specifies the source of the specimen (respiratory organs or thorax) to justify its use over more general abnormal immunological findings codes.
