Code Description

ICD-10 N76.6 is a billable code used to indicate a diagnosis of ulceration of vulva.

Key Diagnostic Point:

Ulceration of the vulva refers to the presence of open sores or lesions on the external female genitalia, which can arise from various underlying conditions. This condition may be associated with Bartholin's gland disorders, where cysts or abscesses can lead to secondary ulceration. Vulvovaginitis, an inflammation of the vulva and vagina, can also contribute to ulceration due to irritation, infection, or allergic reactions. Inflammatory conditions such as lichen sclerosus or vulvar vestibulitis may present with ulcerative lesions as well. The etiology of vulvar ulceration can be multifactorial, including infections (e.g., herpes simplex virus, candidiasis), trauma, or dermatological conditions. Diagnosis typically involves a thorough clinical examination, patient history, and may require laboratory tests to identify infectious agents or other underlying causes. Treatment is directed at the underlying cause and may include topical medications, antibiotics, or surgical intervention in cases of severe or persistent ulceration.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of underlying causes leading to ulceration
  • Need for differential diagnosis to rule out infections
  • Potential for co-existing conditions requiring additional coding
  • Variability in clinical presentation and severity

Audit Risk Factors

  • Inadequate documentation of the underlying cause
  • Failure to document co-existing conditions
  • Misclassification of the type of ulceration
  • Lack of clarity in the clinical notes regarding treatment

Specialty Focus

Medical Specialties

Gynecology

Documentation Requirements

Detailed clinical notes including history, examination findings, and treatment plans.

Common Clinical Scenarios

Patients presenting with vulvar pain, itching, or lesions; recurrent vulvovaginitis; Bartholin's gland cysts.

Billing Considerations

Ensure clear documentation of the ulcer's characteristics and any associated symptoms to support the diagnosis.

Dermatology

Documentation Requirements

Comprehensive skin examination findings, including descriptions of lesions and any relevant history.

Common Clinical Scenarios

Patients with dermatological conditions affecting the vulva, such as lichen sclerosus or psoriasis.

Billing Considerations

Document any biopsies or dermatological treatments provided to support coding.

Coding Guidelines

Inclusion Criteria

Use N76.6 When
  • According to ICD
  • 10 guidelines, N76
  • 6 should be used when there is clear documentation of ulceration of the vulva
  • It is important to ensure that the underlying cause is identified and documented, as this may affect treatment and coding

Exclusion Criteria

Do NOT use N76.6 When
  • Exclusion criteria include conditions that are not specifically ulcerative in nature

Vulvectomy, partial

Clinical Scenario

Used in cases where ulceration is severe and surgical intervention is required.

Documentation Requirements

Document the extent of the procedure and the reason for surgical intervention.

Specialty Considerations

Gynecologists should ensure that the surgical notes clearly outline the diagnosis and treatment rationale.

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of vulvar conditions, including ulceration, which aids in better tracking of disease prevalence and treatment outcomes.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of vulvar conditions, including ulceration, which aids in better tracking of disease prevalence and treatment outcomes.

Reimbursement & Billing Impact

The transition to ICD-10 has allowed for more specific coding of vulvar conditions, including ulceration, which aids in better tracking of disease prevalence and treatment outcomes.
