N46.1 (Oligospermia) compared with R86 (Abnormal findings in specimens from male genital organs), from the official CMS tabular data. Do not report these codes together: the official tabular list marks them Excludes1.
Can these codes be reported together?
No — do not report together. R86 carries an Excludes1 note covering N46.1: “oligospermia (N46.1-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
