What This Code Means
F52.9 is the ICD-10-CM diagnosis code for unspecified sexual dysfunction not due to a substance or known physiological condition. Sexual dysfunction of unspecified type that is not caused by substances or medical conditions. F52.9 sits in the ICD-10-CM chapter for mental, behavioral and neurodevelopmental disorders (f01-f99), within the section covering behavioral syndromes associated with physiological disturbances and physical factors (f50-f59).
F52.9 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 is a default code; attempt to obtain more specific information to assign a more precise F52 code.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for F52.9 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
