ICD-10 Code D07.3 – Carcinoma in situ of other and unspecified female genital organs (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D07.3 – Carcinoma in situ of other and unspecified female genital organs
What it is
D07.3 identifies carcinoma in situ affecting female genital organs not named by a more specific code. It means abnormal cells are present in the lining tissue but have not invaded deeper tissues.
Clinical signs
Clinical features vary; refer to documentation. Diagnosis is usually based on pathology showing in situ malignant changes in a female genital site that is other or not otherwise specified.
When to use this code
Use D07.3 when the provider documents carcinoma in situ of a female genital organ that is not specifically indexed elsewhere. It may also fit when the record names an unspecified female genital site and pathology confirms in situ disease. Verify the exact anatomic site before coding.
Do not use for
Do not use this code for invasive malignant neoplasms, benign lesions, or dysplasia without carcinoma in situ. If the documentation identifies a more specific female genital site, code that location instead.
Coding tip
Match the pathology report and provider note to the exact site; if the site is unclear, check documentation before assigning D07.3.
