Is N60.92 an HCC code?
No. N60.92 is a billable ICD-10-CM code but does not map to any HCC category in V28, V24, ESRD, or RxHCC.
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
N60.92 is the ICD-10-CM diagnosis code for unspecified benign mammary dysplasia of left breast. Benign breast tissue changes or lumps in the left breast that cannot be more specifically identified. This is a common, non-cancerous condition affecting breast tissue. N60.92 sits in the ICD-10-CM chapter for diseases of the genitourinary system (n00-n99), within the section covering disorders of breast (n60-n65).
N60.92 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.
Use this code only when the dysplasia type is truly unspecified; if fibrocystic disease or other specific types are documented, use more specific codes.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for N60.92 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Use this code only when the dysplasia type is truly unspecified; if fibrocystic disease or other specific types are documented, use more specific codes
- •Ensure laterality is clearly documented as left breast to avoid using the unspecified breast code
