What This Code Means
R82.994 is the ICD-10-CM diagnosis code for hypercalciuria. Higher than normal levels of calcium in the urine, which increases the risk of calcium-based kidney stone formation. R82.994 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).
R82.994 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.
May indicate hypercalcemia or primary hyperparathyroidism; review for related endocrine codes.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for R82.994 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
