About N44

N44 is the ICD-10-CM diagnosis code for noninflammatory disorders of testis. 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: N44.0 (testis), N44.1 (testis), N44.2 (testis) and N44.8 (testis).

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