About N46

N46 is the ICD-10-CM diagnosis code for male infertility. It belongs to block N40-N53 (diseases of male genital organs) and chapter 14 (diseases of the genitourinary system). It is a header code, so it can't be reported by itself; one of its 4 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: N46.0 (azoospermia), N46.1 (oligospermia), N46.8 (infertility) and N46.9 (unspecified).

Don't report N46 together with the conditions in its Excludes1 note: vasectomy status (Z98.52).

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