N89.4
ICD-10-CMThis code represents the presence of white, thickened patches on the vaginal mucosa, which are typically non-cancerous but can, in rare instances, be precancerous. These lesions are characterized by hyperkeratosis and acanthosis, often resulting from chronic irritation or inflammation.
Apply this code when documentation explicitly states a diagnosis of leukoplakia affecting the vagina. This diagnosis is typically made via visual inspection during a gynecological exam and confirmed by biopsy results.
