I63: Cerebral infarction

Non-billable headerICD-10-CM

I63 is a non-billable header ICD-10-CM code for cerebral infarction. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes2: not included here, but may coexist

The excluded condition is not part of this code, but a patient can have both. You may code both.

chronic, without residual deficits (sequelae) (Z86.73)

Use additional code

Add a secondary code to capture the detail described below.
