What This Code Means
Z48.298 is the ICD-10-CM diagnosis code for encounter for aftercare following other organ transplant. A follow-up visit to monitor recovery and manage complications after receiving a transplant of organs other than bone marrow, such as kidney, liver, heart, or lung. Z48.298 sits in the ICD-10-CM chapter for factors influencing health status and contact with health services (z00-z99), within the section covering encounters for other specific health care (z40-z53).
Z48.298 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.
Specify the type of organ transplant in documentation to ensure accurate coding.
