B37.2Candidiasis of skin and nail

B37.2 is the ICD-10-CM diagnosis code for candidiasis of skin and nail. 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 (candidiasis), B37.2 is specifically for candidiasis of skin and nail. Related codes cover Candidal stomatitis (B37.0), pulmonary candidiasis (B37.1), of vulva and vagina (B37.3), of other urogenital sites (B37.4), Candidal meningitis (B37.5), Candidal endocarditis (B37.6), Candidal sepsis (B37.7), of other sites (B37.8) and 1 more.

The conditions in its Excludes2 note aren't part of B37.2, but may be coded alongside it if the patient has both: diaper dermatitis (L22).

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 606 (Minor Skin Disorders with MCC, relative weight 1.5728), DRG 607 (Minor Skin Disorders without MCC, relative weight 0.8772), DRG 974 (HIV with Major Related Condition with MCC, relative weight 3.0506), DRG 975 (HIV with Major Related Condition with CC, relative weight 1.3252) and DRG 976 (HIV with Major Related Condition without CC/MCC, relative weight 0.8124), in MDC 09 (Diseases and Disorders of the Skin, Subcutaneous Tissue and Breast) and MDC 25 (Human Immunodeficiency Virus Infections), 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 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 112.3 (candidiasis of skin and nails).
