What This Code Means
N46.9 is the ICD-10-CM diagnosis code for male infertility, unspecified. Male infertility where the specific cause has not been identified or documented. N46.9 sits in the ICD-10-CM chapter for diseases of the genitourinary system (n00-n99), within the section covering diseases of male genital organs (n40-n53).
N46.9 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 the least specific code; use only when the cause is truly unknown or undocumented.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for N46.9 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
