N29 vs N35.1
N29 (Other disorders of kidney and ureter in diseases classified elsewhere) compared with N35.1 (Postinfective urethral stricture, not elsewhere classified), 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. N35.1 carries an Excludes1 note covering N29: “urethral stricture associated with schistosomiasis (B65.-, N29)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
