What This Code Means
Z91.841 is the ICD-10-CM diagnosis code for risk for dental caries, low. A patient assessment indicating low risk for developing cavities or tooth decay based on current oral health status. Z91.841 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).
Z91.841 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.
These dental risk codes are used for preventive dentistry and oral health counseling.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for Z91.841 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
