I63 — Cerebral infarction

Not billable

Is I63 billable?

No — I63 is a non-billable header code. I63 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 60 billable codes beneath I63.

neonatal cerebral infarction (P91.82-)

Use additional code

Report an additional code alongside I63 to fully describe the condition. I63 is sequenced first.

Excludes2 — not included here
