What This Code Means
Z86.018 is the ICD-10-CM diagnosis code for personal history of other benign neoplasm. A patient has a history of a benign tumor at a body site not specifically listed in other history codes. Z86.018 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).
Z86.018 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 benign neoplasms such as lipomas, fibromas, or other non-cancerous growths.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for Z86.018 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Use this code for benign neoplasms such as lipomas, fibromas, or other non-cancerous growths
- •Verify that a more specific history code does not exist for the particular benign tumor type
