What This Code Means
D07.1 is the ICD-10-CM diagnosis code for carcinoma in situ of vulva. Abnormal cells found on the vulva (external female genitalia) that have not yet become invasive cancer. D07.1 sits in the ICD-10-CM chapter for neoplasms (c00-d49), within the section covering in situ neoplasms (d00-d09).
D07.1 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
Vulva refers to the external female genitalia; distinguish from vaginal carcinoma in situ (D07.2).
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for D07.1 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Vulva refers to the external female genitalia; distinguish from vaginal carcinoma in situ (D07.2)
- •Often associated with vulvar intraepithelial neoplasia (VIN); document any visible lesions or symptoms
