Herpesviral vulvovaginitis

This code represents an inflammation of the vulva and vagina caused by the herpes simplex virus (HSV). It typically presents with painful vesicular or ulcerative lesions in the anogenital area, often accompanied by itching, dysuria, and systemic symptoms like fever and malaise.

Use this code when documentation explicitly states a diagnosis of vulvovaginitis due to herpesvirus. This diagnosis is often supported by a positive viral culture, PCR test, or direct fluorescent antibody (DFA) test for HSV, along with characteristic clinical findings.

• Differentiate from other causes of vulvovaginitis (e.g., candidiasis, bacterial vaginosis) which have distinct ICD-10-CM codes.
• Consider sequencing this code as the primary diagnosis if it is the main reason for the encounter.
• Ensure the medical record clearly specifies the viral etiology to support the use of this specific code.
