N36.8 vs Q64.7
N36.8 (Other specified disorders of urethra) compared with Q64.7 (Other and unspecified congenital malformations of bladder and urethra), 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. N36.8 carries an Excludes1 note covering Q64.7: “congenital urethrocele (Q64.7)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
