What This Code Means
N48.0 is the ICD-10-CM diagnosis code for leukoplakia of penis. Abnormal white patches or discolored areas on the skin of the penis that may indicate precancerous changes. N48.0 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).
N48.0 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 potentially precancerous condition; ensure biopsy results are documented if available.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for N48.0 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •This is a potentially precancerous condition; ensure biopsy results are documented if available
- •Monitor for progression and document any treatment or follow-up recommendations
