ICD-10 Code D07.30 – Carcinoma in situ of unspecified female genital organs (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D07.30 – Carcinoma in situ of unspecified female genital organs
What it is
D07.30 identifies carcinoma in situ in a female genital site that is not further specified. It means abnormal cells are confined to the surface layer and have not invaded deeper tissue.
Clinical signs
Clinical features vary; refer to documentation. Diagnosis is usually based on pathology showing in situ malignant change in a female genital organ, with no evidence of invasion.
When to use this code
Use D07.30 when the record states carcinoma in situ involving a female genital organ, but the exact site is not documented. It also fits when pathology confirms in situ disease and the provider does not specify cervix, vulva, vagina, or another site. Code only from documented findings.
Do not use for
Do not use this code for invasive malignancy, dysplasia without carcinoma in situ, or a clearly documented site with a more specific ICD-10 option. Check documentation.
Coding tip
If the site is mentioned anywhere in the chart, code the more specific diagnosis instead of D07.30.
