What This Code Means
Z01.20 is the ICD-10-CM diagnosis code for encounter for dental examination and cleaning without abnormal findings. A routine dental checkup and cleaning with no problems or abnormalities found. Z01.20 sits in the ICD-10-CM chapter for factors influencing health status and contact with health services (z00-z99), within the section covering persons encountering health services for examinations (z00-z13).
Z01.20 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.
Appropriate for preventive dental visits with normal examination results.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for Z01.20 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
