About coding balanitis candidiasis
The ICD-10-CM code for balanitis candidiasis is B37.42 (Candidal balanitis).
Within B37.4 (candidiasis of other urogenital sites), B37.42 is specifically for Candidal balanitis. Related codes cover Candidal cystitis and urethritis (B37.41) and other urogenital candidiasis (B37.49).
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.
