About Q55.2

Q55.2 is the ICD-10-CM diagnosis code for other and unspecified congenital malformations of testis and scrotum. It belongs to category Q55 (other congenital malformations of male genital organs), block Q50-Q56 (congenital malformations of genital organs) 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 5 subcodes must be used instead.

Within Q55, choose Q55.2 (Other and unspecified congenital malformations of testis and scrotum) only when documentation doesn't support a more specific option: absence and aplasia of testis (Q55.0), hypoplasia of testis and scrotum (Q55.1), atresia of vas deferens (Q55.3), other congenital malformations of vas deferens, epididymis, seminal vesicles and prostate (Q55.4), congenital absence and aplasia of penis (Q55.5), other congenital malformations of penis (Q55.6), congenital vasocutaneous fistula (Q55.7), other specified congenital malformations of male genital organs (Q55.8) and 1 more.

To report this condition, pick the subcode that matches the documentation: Q55.20 (scrotum), Q55.21 (Polyorchism), Q55.22 (testis), Q55.23 (transposition) and Q55.29 (scrotum).

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