Q64.7 vs Q79.4
Q64.7 (Other and unspecified congenital malformations of bladder and urethra) compared with Q79.4 (Prune belly syndrome), 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. Q64.7 carries an Excludes1 note covering Q79.4: “congenital prolapse of bladder (mucosa) (Q79.4)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
