About Q64.7

Q64.7 is the ICD-10-CM diagnosis code for other and unspecified congenital malformations of bladder and urethra. It belongs to category Q64 (other congenital malformations of urinary system), block Q60-Q64 (congenital malformations of the urinary system) and chapter 17 (congenital malformations, deformations, chromosomal abnormalities, and genetic disorders). It is a header code, so it can't be reported by itself; one of its 7 subcodes must be used instead.

Within Q64, choose Q64.7 (Other and unspecified congenital malformations of bladder and urethra) only when documentation doesn't support a more specific option: epispadias (Q64.0), exstrophy of urinary bladder (Q64.1), congenital posterior urethral valves (Q64.2), other atresia and stenosis of urethra and bladder neck (Q64.3), malformation of urachus (Q64.4), congenital absence of bladder and urethra (Q64.5), congenital diverticulum of bladder (Q64.6), other specified congenital malformations of urinary system (Q64.8) and 1 more.

To report this condition, pick the subcode that matches the documentation: Q64.70 (urethra), Q64.71 (urethra), Q64.72 (meatus), Q64.73 (fistula), Q64.74 (urethra), Q64.75 (meatus) and Q64.79 (urethra).

Don't report Q64.7 together with the conditions in its Excludes1 note: congenital prolapse of bladder (mucosa) (Q79.4).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
