About coding chronic prostatitis

Related codes cover acute prostatitis (N41.0), abscess of prostate (N41.2), Prostatocystitis (N41.3), granulomatous prostatitis (N41.4), other inflammatory diseases of prostate (N41.8) and inflammatory disease of prostate, unspecified (N41.9).
Use an additional code (B95-B97), to identify infectious agent.
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
