ICD-10 Code D07.39 – Carcinoma in situ of other female genital organs (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D07.39 – Carcinoma in situ of other female genital organs
What it is
D07.39 identifies carcinoma in situ, a noninvasive malignant change, in female genital organs not named by a more specific ICD-10 code. Use it when documentation states a localized in situ lesion without stromal invasion.
Clinical signs
Clinical features vary; refer to documentation. Diagnosis is usually based on pathology showing carcinoma in situ with no evidence of invasion into deeper tissue.
When to use this code
Use D07.39 when the provider documents carcinoma in situ of a female genital site other than cervix, vulva, or vagina, and no more specific code applies. It also fits pathology-confirmed in situ disease when the exact anatomic site is recorded as another female genital organ.
Do not use for
Do not use this code for invasive malignancy, dysplasia without carcinoma in situ, or when a site-specific code is documented. Check documentation if the record only says “abnormal cells” or “precancerous lesion.”
Coding tip
Match the diagnosis wording to the exact anatomic site; if the site is unclear, query the provider before assigning D07.39.
