ICD-10 Code D07 – Carcinoma in situ of other and unspecified genital organs (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D07 – Carcinoma in situ of other and unspecified genital organs
What it is
D07 identifies carcinoma in situ involving genital organs that are not separately named in more specific ICD-10 codes, or when the site is unspecified. It indicates a noninvasive epithelial neoplasm confined to the original tissue layer.
Clinical signs
Clinical features vary; refer to documentation. Diagnosis is usually based on pathology showing carcinoma in situ, with no evidence of stromal invasion or metastatic spread.
When to use this code
Use D07 when the provider documents carcinoma in situ of a genital organ that falls outside a more specific site code, or when the exact genital site is not stated. You may also use it when pathology confirms in situ disease and the record does not specify a narrower location.
Check documentation if the note names a specific organ, because a more precise ICD-10 code may apply. Do not assign D07 for invasive cancer, dysplasia alone, or uncertain pathology.
Do not use for
Do not use D07 for invasive malignant neoplasms, benign lesions, or cervical, vulvar, vaginal, penile, or scrotal sites that have their own more specific codes. If the diagnosis is only abnormal cytology or dysplasia, check documentation.
Coding tip
Code the most specific genital site available first; use D07 only when the record supports in situ disease but does not support a more exact location.
