I79.8 — Other disorders of arteries, arterioles and capillaries in diseases classified elsewhere
I79.8 is a billable, specific ICD-10-CM code for other disorders of arteries, arterioles and capillaries in diseases classified elsewhere. It is valid for submission on a claim.
Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
Code first
The underlying condition must be sequenced before this code.
- underlying disease, such as:
- amyloidosis (E85.-)
Risk adjustment
I79.8 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.
Medicare coverage
I79.8 is named in 13 Medicare coverage policies — 13 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
