What This Code Means
Z85.118 is the ICD-10-CM diagnosis code for personal history of other malignant neoplasm of bronchus and lung. A person who previously had cancer of the bronchus or lung that was not a carcinoid tumor. Z85.118 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).
Z85.118 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 non-carcinoid lung cancers such as adenocarcinoma, squamous cell carcinoma, or small cell carcinoma.
