What This Code Means
R93.89 is the ICD-10-CM diagnosis code for abnormal findings on diagnostic imaging of other specified body structures. An imaging test shows an abnormal finding in a body part or structure not covered by other specific codes. R93.89 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).
R93.89 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 is a catch-all code for abnormal imaging findings; always specify which body structure was imaged in documentation.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for R93.89 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •This is a catch-all code for abnormal imaging findings; always specify which body structure was imaged in documentation
- •Review the imaging report carefully to determine if a more specific R93 code applies before using this code
