I68 is a non-billable ICD-10-CM category code for cerebrovascular disorders in diseases classified elsewhere, so it cannot be submitted on claims. Use a more specific code from this category instead, such as I68.0, I68.2, and I68.8.

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to I68: its own notes plus those printed at block I60-I69 and Chapter 9. A note printed at a category, block or chapter applies to every code under it.

From Block I60-I69 Cerebrovascular diseases applies to 410 codes
  • traumatic intracranial hemorrhage (S06.-)

Excludes2

Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

From Chapter 9 (I00-I99) Diseases of the circulatory system applies to 1,433 codes

Brain Diseases

Your brain is the control center of your body. It controls your thoughts, memory, speech, and movement. It regulates the function of many organs. It's part of your nervous system, which also includes your spinal cord and peripheral nerves. The nervous system sends signals between your brain and the rest of the body.

Questions About I68Overview

What is the ICD-10 code for cerebrovascular disorders in diseases classified elsewhere?

I68 is the ICD-10-CM category for cerebrovascular disorders in diseases classified elsewhere, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is I68 (Cerebrovascular disorders in diseases classified elsewhere) a billable code?

No. This is a category header that groups the codes for cerebrovascular disorders in diseases classified elsewhere, and headers cannot be submitted on claims. Claims for cerebrovascular disorders in diseases classified elsewhere need a more specific code from this category, such as I68.0, I68.2, and I68.8.

Can I68 be reported with a code from S06?

Not as a rule. The Excludes1 note at block I60-I69, which applies to I68, lists "traumatic intracranial hemorrhage (S06.-)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
