Is N04.7 an HCC code?
No. N04.7 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
N04.7 is the ICD-10-CM diagnosis code for nephrotic syndrome with diffuse crescentic glomerulonephritis. A severe kidney condition where crescent-shaped scars form in the kidney's filtering units, causing rapid protein loss and potentially rapid kidney failure. N04.7 sits in the ICD-10-CM chapter for diseases of the genitourinary system (n00-n99), within the section covering glomerular diseases (n00-n08).
N04.7 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.
Crescentic glomerulonephritis is a serious pattern often requiring urgent treatment; ensure documentation reflects the severity and urgency of the condition.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for N04.7 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Crescentic glomerulonephritis is a serious pattern often requiring urgent treatment; ensure documentation reflects the severity and urgency of the condition
- •This pattern is associated with ANCA-associated vasculitis and other systemic diseases; document any associated diagnoses
