What This Code Means
Z87.09 is the ICD-10-CM diagnosis code for personal history of other diseases of the respiratory system. A patient has a history of other lung or respiratory system diseases (such as asthma, bronchitis, or COPD) that may affect current treatment. Z87.09 sits in the ICD-10-CM chapter for factors influencing health status and contact with health services (z00-z99), within the section covering persons with potential health hazards related to family and personal history and certain conditions influencing health status (z77-z99).
Z87.09 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
Use this code for respiratory conditions other than recurrent pneumonia; specify the actual condition when possible for better documentation.
