Is N14.11 an HCC code?
No. N14.11 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
N14.11 is the ICD-10-CM diagnosis code for contrast-induced nephropathy. Kidney damage that occurs as a reaction to contrast dye used during medical imaging procedures like CT scans or angiograms. N14.11 sits in the ICD-10-CM chapter for diseases of the genitourinary system (n00-n99), within the section covering renal tubulo-interstitial diseases (n10-n16).
N14.11 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.
Document the date of contrast exposure and the imaging procedure performed.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for N14.11 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Document the date of contrast exposure and the imaging procedure performed
- •Note baseline kidney function and risk factors (diabetes, dehydration) in the record
