Is Z86.15 an HCC code?

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
Z86.15 is the ICD-10-CM diagnosis code for personal history of latent tuberculosis infection. A patient who has been exposed to tuberculosis and has the dormant infection in their body but is not currently sick. Z86.15 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).
Z86.15 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.
Distinguish this from Z86.11 (active TB history) and from R76.11 (positive TB skin test without disease).
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for Z86.15 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
