What This Code Means
Z48.815 is the ICD-10-CM diagnosis code for encounter for surgical aftercare following surgery on the digestive system. A follow-up visit for recovery and monitoring after surgery on the stomach, intestines, liver, pancreas, or other digestive organs. Z48.815 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).
Z48.815 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 which digestive organ was operated on (e.g., appendectomy, gastrectomy, colostomy).
