ICD-10 Code D28.1 – Benign neoplasm of vagina (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D28.1 – Benign neoplasm of vagina
What it is
D28.1 identifies a noncancerous growth arising in the vagina. Use it when documentation states a benign vaginal tumor, mass, or neoplasm.
Clinical signs
Clinical features vary; refer to documentation. A benign vaginal lesion may be found on pelvic exam or imaging, and may be described as a localized vaginal mass.
When to use this code
Use D28.1 when the provider documents a benign neoplasm of the vagina as the diagnosis. It also fits follow-up visits for an established benign vaginal tumor when the condition remains active. If the record only says “vaginal mass” or “lesion,” check documentation before assigning the code.
Do not use for
Do not use this code for malignant vaginal neoplasms, benign neoplasms of other genital sites, or nonspecific symptoms without a documented neoplasm. Check documentation.
Coding tip
Code the site exactly as documented; vaginal and vulvar lesions are not interchangeable.
