2025 ICD-10-CM code Z86.73
Personal history of transient ischemic attack (TIA), and cerebral infarction without residual deficits.This also includes a personal history of prolonged reversible ischemic neurological deficit (PRIND) or stroke without residual deficits.
The medical necessity for using this code is to document a past event of TIA, cerebral infarction, or PRIND when there are no current symptoms or residual deficits. It helps provide a complete medical history for the patient.
The provider must document the past occurrence of a TIA or cerebral infarction and the absence of any residual deficits.Any follow-up care related to the history of TIA or cerebral infarction should also be documented.
In simple words: This code indicates that the patient has a history of a transient ischemic attack (TIA) or a minor stroke (cerebral infarction) but does not currently have any lasting effects from these events.A TIA is often called a "mini-stroke" and is caused by a temporary blockage of blood flow to the brain.A cerebral infarction is a type of stroke where blood flow to part of the brain is stopped long enough to cause some damage.This code indicates the patient had one of these events in the past, but has recovered fully.
Personal history of transient ischemic attack (TIA), and cerebral infarction without residual deficits.This also includes a personal history of prolonged reversible ischemic neurological deficit (PRIND) or stroke without residual deficits. Excludes1: personal history of traumatic brain injury (Z87.820) sequelae of cerebrovascular disease (I69.-)Excludes2: old myocardial infarction (I25.2) personal history of anaphylactic shock (Z87.892) postmyocardial infarction syndrome (I24.1)
Example 1: A patient presents for an annual physical.During the review of medical history, the patient reports having a TIA two years ago with no lasting effects.The patient fully recovered, has no current symptoms, and is not currently undergoing treatment for the TIA. Z86.73 is the appropriate code., A patient is seen for a medication refill for hypertension.The patient's medical history includes a cerebral infarction five years prior with no residual deficits. The patient has no current symptoms related to the prior stroke.Z86.73 is appropriate., A patient presents with a new complaint of chest pain. The physician notes a history of PRIND (prolonged reversible ischemic neurological deficit) one year ago. The patient has fully recovered with no remaining deficits. Z86.73 is reported along with the appropriate code(s) for the chest pain.
Documentation should clearly state the past occurrence of TIA, cerebral infarction, or PRIND, and explicitly note the absence of any residual deficits. Dates of the prior event(s) should be documented if known.
** Code first any follow-up examination after treatment (Z09).
