CodeDescriptionWhen to UseKey Documentation
B37.3Candidiasis of vulva and vaginaUse when both vulvar and vaginal involvement are documented.
  • Positive KOH prep showing budding yeast
  • Thick white vaginal discharge
  • Vulvar erythema
B37.0Candidiasis of mouthUse when oral thrush is confirmed by clinical and lab findings.
  • Pseudomembranous plaques on buccal mucosa
  • Positive fungal smear
B37.9Candidiasis, unspecifiedUse only when the site of candidiasis is not documented.
  • General symptoms without specific site documentation

Clinical Decision Support

Always review the patient's clinical documentation thoroughly. When in doubt, choose the more specific code and ensure documentation supports it.

Applicable To

  • Vulvovaginal candidiasis

Excludes

  • Candidiasis of other sites

Clinical Validation Requirements

  • Positive KOH prep showing budding yeast
  • Thick white vaginal discharge
  • Vulvar erythema

Code-Specific Risks

  • Ensure documentation specifies both vulvar and vaginal involvement.

Ancillary Codes

Additional codes that should be used in conjunction with the main diagnosis codes when applicable.

Differential Codes

Alternative codes to consider when ruling out similar conditions to the primary diagnosis.

Oral thrush

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Yeast Infection to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code B37.3.

Impact

Clinical: May lead to incorrect treatment., Regulatory: Increases risk of audit., Financial: Potential for denied claims.

Mitigation Strategy

Ensure thorough documentation of site., Use lab tests to confirm diagnosis.

Impact

Reimbursement: May lead to reduced reimbursement due to lack of specificity., Compliance: Increases risk of audit and compliance issues., Data Quality: Decreases accuracy of clinical data.

Mitigation Strategy

Ensure specific site is documented and use the appropriate code.

Impact

Use of unspecified codes increases audit risk.

Mitigation Strategy

Document specific site and use appropriate code.

Documentation errors, coding pitfalls, and audit risks are interconnected aspects of medical coding and billing. Addressing all three areas helps ensure accurate coding, optimal reimbursement, and regulatory compliance.

Documentation Templates for Yeast Infection

Use these documentation templates to ensure complete and accurate documentation for Yeast Infection. These templates include all required elements for proper coding and billing.

Vulvovaginal Candidiasis

Specialty: Gynecology

Required Elements

  • Patient history
  • Physical examination findings
  • Lab results
  • Diagnosis
  • Treatment plan

Example Documentation

Patient presents with thick white vaginal discharge and vulvar erythema. KOH prep shows budding yeast. Diagnosed with vulvovaginal candidiasis. Prescribed fluconazole.

Examples: Poor vs. Good Documentation

Poor Documentation Example
Yeast infection, prescribe cream.
Good Documentation Example
Severe vulvar edema with satellite lesions, pH 4.5 on vaginal swab, Gram stain confirms Candida species. Diagnosed as complicated vulvovaginal candidiasis.
Explanation
The good example provides specific site involvement and lab confirmation, supporting the use of a specific code.
