What This Code Means
R85.89 is the ICD-10-CM diagnosis code for other abnormal findings in specimens from digestive organs and abdominal cavity. A tissue sample from the digestive system or abdominal area shows some other type of abnormal finding not covered by more specific codes. R85.89 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 examination of other body fluids, substances and tissues, without diagnosis (r83-r89).
R85.89 is a billable ICD-10-CM code, but the current payload does not show a mapping under the CMS-HCC V28, V24, ESRD, or RxHCC models. Do not assign risk adjustment value from this page when no source-backed mapping is shown; verify the applicable model and payment year.
Use this code for miscellaneous abnormal findings such as unusual organisms, inflammatory changes, or other non-standard results.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for R85.89 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Use this code for miscellaneous abnormal findings such as unusual organisms, inflammatory changes, or other non-standard results
