About N42.8

N42.8 is the ICD-10-CM diagnosis code for other specified disorders of prostate. It belongs to category N42 (other and unspecified disorders of prostate), 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.

Within N42, choose N42.8 (Other specified disorders of prostate) only when documentation doesn't support a more specific option: calculus of prostate (N42.0), congestion and hemorrhage of prostate (N42.1), dysplasia of prostate (N42.3) and disorder of prostate, unspecified (N42.9).

To report this condition, pick the subcode that matches the documentation: N42.81 (syndrome), N42.82 (syndrome), N42.83 (prostate) and N42.89 (prostate).

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