I63.112 is a billable, specific ICD-10-CM code for cerebral infarction due to embolism of left vertebral artery. It is valid for submission on a claim.
Excludes1 inherited from the categories above I63.112
These are not written on I63.112, but they bind it: a note on a category applies to every code beneath it. Billing I63.112 with anything listed here is a denial.
Excludes2 inherited from the categories above I63.112
Also inherited, and the opposite of Excludes1: these conditions are not part of I63.112, but a patient can have both, so you may code both.
Other codes that can never be billed with I63.112
These codes carry an Excludes1 note pointing at I63.112. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading I63.112 alone.
