ICD-10 Code B37.89 – Other sites of candidiasis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B37.89 – Other sites of candidiasis
What it is
B37.89 identifies candidiasis caused by Candida species in body sites not named by a more specific ICD-10 code. Use it when the record clearly documents a Candida infection, but the location is outside the usual listed categories.
Clinical signs
Clinical features vary; refer to documentation. You may see localized redness, irritation, soreness, discharge, or other findings consistent with a Candida infection at an unusual site.
When to use this code
Use B37.89 when the provider documents candidiasis at another specified site and no more specific code applies. It is appropriate for site-specific Candida infections that are not vaginal, oral, esophageal, or otherwise separately classified. If the site is unclear, check documentation before coding.
Do not use for
Do not use this code for common, separately coded candidiasis sites such as oral, esophageal, vulvovaginal, or cutaneous disease. If the record only says “Candida infection” without a site, check documentation.
Coding tip
Capture the exact anatomic site in the chart, because B37.89 is a residual code used only when no more specific candidiasis code fits.
