About coding prostate trichomoniasis
The ICD-10-CM code for prostate trichomoniasis is A59.02 (Trichomonal prostatitis).
Within A59.0 (urogenital trichomoniasis), A59.02 is specifically for Trichomonal prostatitis. Related codes cover unspecified (A59.00), Trichomonal vulvovaginitis (A59.01), Trichomonal cystitis and urethritis (A59.03) and other urogenital trichomoniasis (A59.09).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 727 (Inflammation of the Male Reproductive System with MCC, relative weight 1.37) and DRG 728 (Inflammation of the Male Reproductive System without MCC, relative weight 0.8224), in MDC 12 (Diseases and Disorders of the Male Reproductive System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
