What This Code Means
R85.2 is the ICD-10-CM diagnosis code for abnormal level of other drugs, medicaments and biological substances in specimens from digestive organs and abdominal cavity. Laboratory test results from digestive system samples showing abnormal levels of medications, drugs, or biological substances. R85.2 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).
R85.2 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 drug or medication levels are detected in specimens from the GI tract or abdominal cavity.
