What This Code Means
Z48.817 is the ICD-10-CM diagnosis code for encounter for surgical aftercare following surgery on the skin and subcutaneous tissue. A follow-up visit to check on healing and recovery after surgery on the skin or underlying tissue layers. Z48.817 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).
Z48.817 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.
Use this code for post-operative wound checks, suture removal, or dressing changes following skin/subcutaneous surgery.
