| G45 | Transient Ischemic Attack (TIA) | Temporary stroke-like symptoms with no damage |
Detailed Explanation of Each Code
I63 – Ischemic Stroke
This is the most common type of CVA.
It happens when a clot blocks blood flow to the brain.
ICD 10 further breaks this down into subcategories (e.g., I63.0 – Cerebral infarction due to thrombosis).
Doctors must specify the cause and affected artery when using this code.
I61 – Hemorrhagic Stroke
This code refers to bleeding within the brain tissue.
It includes subtypes like I61.0 – Intracerebral hemorrhage in hemisphere, subcortical.
Use this code when imaging confirms a bleed.
I64 – Stroke, Not Specified as Hemorrhage or Infarction
Used when stroke type isn’t confirmed at the time of diagnosis.
Once clarified, update to a more specific CVA ICD 10 code like I63 or I61.
G45 – Transient Ischemic Attack (TIA)
Sometimes called a “mini-stroke,” this occurs when symptoms resolve in 24 hours.
Though not a true stroke, it’s an important warning sign of future CVAs.
How to Identify the Correct CVA ICD 10 Code
To select the correct code:
- Confirm the stroke type: Ischemic or hemorrhagic?
- Identify the affected artery or brain region.
- Check medical imaging or tests to support the diagnosis.
- Use specific subcodes if available, especially for detailed cases.
Importance of Precision in CVA ICD 10 Coding
Accurate use of CVA ICD 10 codes ensures correct treatment and billing.
