About N39

N39 is the ICD-10-CM diagnosis code for other disorders of urinary system. It belongs to block N30-N39 (other diseases of the urinary system) 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.

To report this condition, pick the subcode that matches the documentation: N39.0 (specified), N39.3 ((male)), N39.4 (incontinence), N39.8 (system) and N39.9 (unspecified).

The conditions in its Excludes2 note aren't part of N39, but may be coded alongside it if the patient has both: hematuria NOS (R31.-), recurrent or persistent hematuria (N02.-), recurrent or persistent hematuria with specified morphological lesion (N02.-) and proteinuria NOS (R80.-).

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