About B37.0

B37.0 is the ICD-10-CM diagnosis code for Candidal stomatitis. 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), B37.0 is specifically for Candidal stomatitis. Related codes cover pulmonary candidiasis (B37.1), of skin and nail (B37.2), 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.

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 011 (Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy with MCC, relative weight 5.6154), DRG 012 (Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy with CC, relative weight 4.381), DRG 013 (Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy without CC/MCC, relative weight 2.7307), DRG 157 (Dental and Oral Diseases with MCC, relative weight 1.809), DRG 158 (Dental and Oral Diseases with CC, relative weight 0.9366), DRG 159 (Dental and Oral Diseases without CC/MCC, relative weight 0.6893) and 3 more, in Pre-MDC, MDC 03 (Diseases and Disorders of the Ear, Nose, Mouth and Throat) 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 112.0 (candidiasis of mouth).
