About N41

N41 is the ICD-10-CM diagnosis code for inflammatory diseases of prostate. 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 7 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: N41.0 (prostatitis), N41.1 (prostatitis), N41.2 (prostate), N41.3 (Prostatocystitis), N41.4 (prostatitis), N41.8 (prostate) and N41.9 (unspecified).

Use an additional code (B95-B97), to identify infectious agent.

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