N32.0 vs Q64.3
N32.0 (Bladder-neck obstruction) compared with Q64.3 (Other atresia and stenosis of urethra and bladder neck), 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. N32.0 carries an Excludes1 note covering Q64.3: “congenital bladder-neck obstruction (Q64.3-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
