About B37.42

B37.42 is the ICD-10-CM diagnosis code for Candidal balanitis. It belongs to category B37 (candidiasis), block B35-B49 (mycoses) and chapter 1 (certain infectious and parasitic diseases). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

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.

It is on the CMS list of diagnoses consistent only with male patients (the sex-conflict edit itself was retired in FY2025).

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

Before ICD-10, this condition was coded in ICD-9-CM as 112.2 (candidiasis of other urogenital sites).
