Is N98.3 an HCC code?
No. N98.3 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
N98.3 is the ICD-10-CM diagnosis code for complications of attempted introduction of embryo in embryo transfer. Problems or complications that occur when an embryo is being transferred into the uterus during an embryo transfer procedure. N98.3 sits in the ICD-10-CM chapter for diseases of the genitourinary system (n00-n99), within the section covering noninflammatory disorders of female genital tract (n80-n98).
N98.3 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.
Distinguish between N98.2 (fertilized ovum from IVF) and N98.3 (embryo transfer) based on the procedure performed.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for N98.3 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
