Is R94.39 an HCC code?
No. R94.39 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
R94.39 is the ICD-10-CM diagnosis code for abnormal result of other cardiovascular function study. Test results showing abnormal heart or blood vessel function that don't fit into other specific categories, such as unusual findings from cardiac imaging or stress tests. R94.39 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 diagnostic imaging and in function studies, without diagnosis (r90-r94).
R94.39 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.
Use this code when cardiovascular function study results are abnormal but don't meet criteria for more specific R94.3x codes.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for R94.39 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Use this code when cardiovascular function study results are abnormal but don't meet criteria for more specific R94.3x codes
