Y84.0 ICD-10-CM Code: Cardiac catheterization as the cause of abnormal reaction of the patient, or of later complication, without mention of misadventure at the time of the procedure

Y84.0 is the ICD-10-CM diagnosis code for cardiac catheterization as the cause of abnormal reaction of the patient, or of later complication, without mention of misadventure at the time of the procedure. A complication or abnormal reaction that occurred after a cardiac catheterization procedure (a test where a tube is inserted into heart blood vessels), not due to a mistake during the procedure itself. Y84.0 sits in the ICD-10-CM chapter for external causes of morbidity (v00-y99), within the section covering surgical and other medical procedures as the cause of abnormal reaction of the patient, or of later complication, without mention of misadventure at the time of the procedure (y83-y84).

Y84.0 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 when documenting complications that develop after cardiac catheterization, such as arrhythmias, infection, or vessel damage.
