What This Code Means
R46.6 is the ICD-10-CM diagnosis code for undue concern and preoccupation with stressful events. Excessive worry or preoccupation with stressful events or situations, often appearing anxious or overly focused on potential problems. R46.6 sits in the ICD-10-CM chapter for symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (r00-r99), within the section covering symptoms and signs involving cognition, perception, emotional state and behavior (r40-r46).
R46.6 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.
Document what specific stressful events the patient is preoccupied with.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for R46.6 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
