About N44.0
N44.0 is the ICD-10-CM diagnosis code for torsion of testis. It belongs to category N44 (noninflammatory disorders of testis), 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 5 subcodes must be used instead.
Within N44 (noninflammatory disorders of testis), N44.0 is specifically for torsion of testis. Related codes cover cyst of tunica albuginea testis (N44.1), benign cyst of testis (N44.2) and other noninflammatory disorders of the testis (N44.8).
To report this condition, pick the subcode that matches the documentation: N44.00 (unspecified), N44.01 (cord), N44.02 (cord), N44.03 (testis) and N44.04 (epididymis).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
