What This Code Means
D06.9 is the ICD-10-CM diagnosis code for carcinoma in situ of cervix, unspecified. Abnormal cells found in the cervix with an unspecified location that have not yet become invasive cancer. D06.9 sits in the ICD-10-CM chapter for neoplasms (c00-d49), within the section covering in situ neoplasms (d00-d09).
D06.9 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.
This is a less specific code; use only when the exact location within the cervix cannot be determined.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for D06.9 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •This is a less specific code; use only when the exact location within the cervix cannot be determined
- •Query the provider or pathology report if more specific anatomical location is available
