What This Code Means
Z86.012 is the ICD-10-CM diagnosis code for personal history of benign carcinoid tumor. A patient has a history of a benign carcinoid tumor, which is a slow-growing neuroendocrine tumor that was previously diagnosed. Z86.012 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).
Z86.012 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.
Carcinoid tumors can occur in various body sites; document the primary location if known.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for Z86.012 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Carcinoid tumors can occur in various body sites; document the primary location if known
- •Even though benign, carcinoid tumors may require ongoing monitoring due to potential hormone secretion
