About coding Cavitary prostatitis
The ICD-10-CM code for Cavitary prostatitis is N41.8 (Other inflammatory diseases of prostate).
Within N41, choose N41.8 (Other inflammatory diseases of prostate) only when documentation doesn't support a more specific option: acute prostatitis (N41.0), chronic prostatitis (N41.1), abscess of prostate (N41.2), Prostatocystitis (N41.3), granulomatous prostatitis (N41.4) 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.
