A18.14 vs N51
A18.14 (Tuberculosis of prostate) compared with N51 (Disorders of male genital organs in diseases classified elsewhere), 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. N51 carries an Excludes1 note covering A18.14: “tuberculous prostatitis (A18.14)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
