Is I67 a billable ICD-10-CM code?

No. I67 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does I67 sit in the tabular list?

Diseases of the circulatory system (I00-I99), in the block Cerebrovascular diseases (I60-I69).

What cannot be coded together with I67?

I67 carries an Excludes1 note, which means the conditions it lists can never be coded together with it on the same encounter.

I67 — Other cerebrovascular diseases

Non-billable headerICD-10-CM

I67 is a non-billable header ICD-10-CM code for other cerebrovascular diseases. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

Occlusion and stenosis of cerebral artery causing cerebral infarction (I63.3-I63.5-)
Occlusion and stenosis of precerebral artery causing cerebral infarction (I63.2-)

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.

sequelae of the listed conditions (I69.8)

Other codes that can never be billed with I67

These codes carry an Excludes1 note pointing at I67. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading I67 alone.

G08Intracranial and intraspinal phlebitis and thrombophlebitis
G93.2Benign intracranial hypertension
I60.7Nontraumatic subarachnoid hemorrhage from unspecified intracranial artery
I72.0Aneurysm of carotid artery
I77.6Arteritis, unspecified

Risk adjustment

I67 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code to one of these instead I67

10 child codes. Green means billable.
