What This Code Means
Z91.110 is the ICD-10-CM diagnosis code for patient's noncompliance with dietary regimen due to financial hardship. A patient is not following their prescribed diet due to inability to afford the required foods or meal plan. Z91.110 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).
Z91.110 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.
This code documents a barrier to compliance; consider social work referral or community resources.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for Z91.110 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
