I70 — Atherosclerosis
Not billable
Is I70 billable?
No — I70 is a non-billable header code. I70 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 I70.

How long has I70 existed?
I70 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
Which codes are confused with I70?
ICD-10-CM declares these codes mutually exclusive with I70 — exactly one of each pair can be correct for a given encounter.
