Is R82.3 an HCC code?
No. R82.3 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
R82.3 is the ICD-10-CM diagnosis code for hemoglobinuria. The presence of hemoglobin (the oxygen-carrying protein in red blood cells) in the urine, indicating red blood cell breakdown or urinary tract bleeding. R82.3 sits in the ICD-10-CM chapter for symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (r00-r99), within the section covering abnormal findings on examination of urine, without diagnosis (r80-r82).
R82.3 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.
Differentiate hemoglobinuria from hematuria; hemoglobinuria indicates intravascular hemolysis.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for R82.3 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Differentiate hemoglobinuria from hematuria; hemoglobinuria indicates intravascular hemolysis
- •Correlate with anemia codes and investigate underlying hemolytic causes
