Z86.73 ICD-10-CM Code: Personal history of transient ischemic attack (TIA), and cerebral infarction without residual deficits

Z86.73 is the ICD-10-CM diagnosis code for personal history of transient ischemic attack (tia), and cerebral infarction without residual deficits. A patient has a history of transient ischemic attack (TIA) or stroke that did not leave permanent neurological damage or deficits. Z86.73 sits in the ICD-10-CM chapter for factors influencing health status and contact with health services (z00-z99), within the section covering persons with potential health hazards related to family and personal history and certain conditions influencing health status (z77-z99).

Z86.73 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.

Personal history of transient ischemic attack and cerebral infarction without residual deficits, status code for resolved prior stroke or TIA. Used when no current sequelae exist.
