Is I70 a billable ICD-10-CM code?

No. I70 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does I70 sit in the tabular list?

Diseases of the circulatory system (I00-I99), in the block Diseases of arteries, arterioles and capillaries (I70-I79).

I70 — Atherosclerosis

Non-billable headerICD-10-CM

I70 is a non-billable header ICD-10-CM code for atherosclerosis. 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.

arteriosclerotic cardiovascular disease (I25.1-)
arteriosclerotic heart disease (I25.1-)
atheroembolism (I75.-)
cerebral atherosclerosis (I67.2)
coronary atherosclerosis (I25.1-)
mesenteric atherosclerosis (K55.1)
precerebral atherosclerosis (I67.2)
primary pulmonary atherosclerosis (I27.0)

Use additional code

Add a secondary code to capture the detail described below.

code to identify:
exposure to environmental tobacco smoke (Z77.22)
history of tobacco dependence (Z87.891)
occupational exposure to environmental tobacco smoke (Z57.31)
tobacco dependence (F17.-)
tobacco use (Z72.0)

Includes

Conditions this code covers.

arteriolosclerosis
arterial degeneration
arteriosclerosis
arteriosclerotic vascular disease
arteriovascular degeneration
atheroma
endarteritis deformans or obliterans
senile arteritis
senile endarteritis
vascular degeneration

Other codes that can never be billed with I70

These codes carry an Excludes1 note pointing at I70. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading I70 alone.

N28.0Ischemia and infarction of kidney
I73.9Peripheral vascular disease, unspecified
I77.6Arteritis, unspecified
I96Gangrene, not elsewhere classified

Risk adjustment

I70 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 I70

10 child codes. Green means billable.
