What This Code Means
R93.5 is the ICD-10-CM diagnosis code for abnormal findings on diagnostic imaging of other abdominal regions, including retroperitoneum. An imaging test reveals an abnormal finding in the abdominal area or the space behind the abdominal organs (retroperitoneum) that needs further investigation. R93.5 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).
R93.5 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.
This code covers findings in organs and structures throughout the abdomen and retroperitoneal space.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for R93.5 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
