What This Code Means
Z09 is the ICD-10-CM diagnosis code for encounter for follow-up examination after completed treatment for conditions other than malignant neoplasm. A patient is having a follow-up examination after completing treatment for a non-cancer condition to ensure recovery and monitor for complications. Z09 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).
Z09 is a billable ICD-10-CM code, but no current CMS-HCC V28 community payment mapping is shown, 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.
This code covers follow-up visits for any completed treatment except malignant neoplasm; use Z08 for cancer follow-ups.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for Z09 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
