R86 ICD-10-CM Code: Abnormal findings in specimens from male genital organs

R86 is the ICD-10-CM diagnosis code for abnormal findings in specimens from male genital organs. R86 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).

Header codes like R86 cannot be reported on claims directly, they organize child codes that share clinical context but the actual diagnosis must be coded to the highest level of specificity supported by the documentation. Coders should look at R86's child codes and select the one that matches the patient's documented presentation, since payers reject header codes submitted as the primary diagnosis. For risk adjustment workflows, header codes never contribute to a Medicare Advantage member's RAF score on their own; only billable child codes that happen to map to a payment HCC affect risk-adjusted plan payments.
