What This Code Means
D06.1 is the ICD-10-CM diagnosis code for carcinoma in situ of exocervix. Abnormal cells found on the outer surface of the cervix that have not yet become invasive cancer. D06.1 sits in the ICD-10-CM chapter for neoplasms (c00-d49), within the section covering in situ neoplasms (d00-d09).
D06.1 is a billable ICD-10-CM code, but the current payload does not show a mapping under the CMS-HCC V28 or V24 community payment models, and none under the ESRD, Part D RxHCC, or HHS-HCC models. Do not assign risk adjustment value from this page when no source-backed mapping is shown; verify the applicable model and payment year.
Exocervix is the visible outer portion of the cervix; distinguish from endocervix (D06.0).
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for D06.1 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
