Transient cerebral ischemic attacks and related syndromes
- ICD-10-CM Code:
- G45
- ICD-10 Code for:
- Transient cerebral ischemic attacks and related syndromes
- Is Billable?
- Not Valid for Submission
- Code Navigator:
G45 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of transient cerebral ischemic attacks and related syndromes. The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.
Specific Coding Applicable to Transient cerebral ischemic attacks and related syndromes
Non-specific codes like G45 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for transient cerebral ischemic attacks and related syndromes:
Use G45.0 for Vertebro-basilar artery syndrome - BILLABLE CODE
Use G45.1 for Carotid artery syndrome (hemispheric) - BILLABLE CODE
Use G45.2 for Multiple and bilateral precerebral artery syndromes - BILLABLE CODE
Use G45.3 for Amaurosis fugax - BILLABLE CODE
Use G45.4 for Transient global amnesia - BILLABLE CODE
Use G45.8 for Other transient cerebral ischemic attacks and related syndromes - BILLABLE CODE
Use G45.9 for Transient cerebral ischemic attack, unspecified - BILLABLE CODE
Tabular List of Diseases and Injuries
The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.
Type 1 Excludes
Type 1 ExcludesA type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
Patient Education
Transient Ischemic Attack
A transient ischemic attack (TIA) is a stroke that lasts only a few minutes. It happens when the blood supply to part of the brain is briefly blocked. Symptoms of a TIA are like other stroke symptoms, but do not last as long. They happen suddenly, and include:
- Numbness or weakness, especially on one side of the body
- Confusion or trouble speaking or understanding speech
- Trouble seeing in one or both eyes
- Difficulty walking
- Dizziness
- Loss of balance or coordination
Most symptoms of a TIA disappear within an hour, although they may last for up to 24 hours. Because you cannot tell if these symptoms are from a TIA or a stroke, you should go to the hospital right away.
TIAs are often a warning sign for future strokes. Taking medicine, such as blood thinners, may reduce your risk of a stroke. Your doctor might also recommend surgery. You can also help lower your risk by having a healthy lifestyle. This includes not smoking, not drinking too much, eating a healthy diet, and exercising. It is also important to control other health problems, such as high blood pressure and cholesterol.
