B37.89 is a billable ICD-10-CM diagnosis code for other sites of candidiasis. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 867 through 869, 974 through 976. As a secondary diagnosis, it counts as a complication or comorbidity (CC) and moves an inpatient stay to a higher severity level within its MS-DRG family.

Questions About B37.89Overview
What is the ICD-10 code for other sites of candidiasis?
The ICD-10-CM code for other sites of candidiasis is B37.89 (sometimes written as B3789). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is B37.89 (Candidiasis of other sites) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report other sites of candidiasis on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does B37.89 group to?
When other sites of candidiasis is the principal diagnosis on an inpatient stay, it groups to MS-DRG 974, 976, 975, 867, 869, 868, with relative weights from 0.6784 to 3.0488 depending on complications. Higher weights mean higher Medicare reimbursement.
Is B37.89 a CC or MCC?
CMS lists B37.89 as a CC (complication or comorbidity) for FY 2027. Reported as a secondary diagnosis, it moves the inpatient stay to a higher-weighted DRG within its severity family. It does not count when the principal diagnosis is one of the 12 closely related codes in its exclusion list.
Can B37.89 be reported with P37.5?
Not as a rule. The Excludes1 note at B37, which applies to B37.89, lists "neonatal candidiasis (P37.5)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
