Candidiasis of skin and nail

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015
LAST UPDATED09/05/2025

Code Description

ICD-10 B36.2 is a billable code used to indicate a diagnosis of candidiasis of skin and nail.

Key Diagnostic Point:

Candidiasis of the skin and nails is a fungal infection caused by Candida species, most commonly Candida albicans. This condition typically manifests as red, itchy, and inflamed skin, often accompanied by a white, curd-like discharge. In the case of nail involvement, it can lead to discoloration, thickening, and separation of the nail from the nail bed. Candidiasis is more prevalent in warm, moist environments and can affect various body areas, including the groin, armpits, and under the breasts. Individuals with compromised immune systems, such as those with diabetes, HIV/AIDS, or those undergoing immunosuppressive therapy, are at a higher risk for developing candidiasis. Diagnosis is primarily clinical, supported by laboratory tests such as KOH preparation or culture. Treatment typically involves topical antifungal agents like clotrimazole or miconazole, and in more severe cases, systemic antifungals such as fluconazole may be necessary. Proper hygiene and moisture control are crucial in preventing recurrence.

  • Identifying the specific Candida species involved.
  • Documenting the extent of skin and nail involvement.
  • Assessing the patient's immunocompromised status.

Audit Risk Factors

  • Inadequate documentation of the patient's immunocompromised status.
  • Failure to specify the site of infection (skin vs. nail).
  • Misidentification of the causative organism.
  • Lack of clarity in treatment plans.

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of candidiasis, improving the ability to track and manage fungal infections. This specificity aids in better patient care and resource allocation.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of candidiasis, improving the ability to track and manage fungal infections. This specificity aids in better patient care and resource allocation.

Reimbursement & Billing Impact

The transition to ICD-10 has allowed for more specific coding of candidiasis, improving the ability to track and manage fungal infections. This specificity aids in better patient care and resource allocation.
