About coding urethritis candidiasis
The ICD-10-CM code for urethritis candidiasis is B37.41 (Candidal cystitis and urethritis).
Within B37.4 (candidiasis of other urogenital sites), B37.41 is specifically for Candidal cystitis and urethritis. Related codes cover Candidal balanitis (B37.42) and other urogenital candidiasis (B37.49).
As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.
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), DRG 728 (Inflammation of the Male Reproductive System without MCC, relative weight 0.8224), DRG 742 (Uterine and Adnexa Procedures for Non-Malignancy with CC/MCC, relative weight 1.8456), DRG 743 (Uterine and Adnexa Procedures for Non-Malignancy without CC/MCC, relative weight 1.2974), DRG 757 (Infections, Female Reproductive System with MCC, relative weight 1.4649), DRG 758 (Infections, Female Reproductive System with CC, relative weight 0.9908) and 1 more, in MDC 12 (Diseases and Disorders of the Male Reproductive System) and MDC 13 (Diseases and Disorders of the Female 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.
