I77.0 — Arteriovenous fistula, acquired
I77.0 is a billable, specific ICD-10-CM code for arteriovenous fistula, acquired. 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.
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.
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Aneurysmal varix
- Arteriovenous aneurysm, acquired
Other codes that can never be billed with I77.0
These codes carry an Excludes1 note pointing at I77.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading I77.0 alone.
- Q27.3Arteriovenous malformation (peripheral)
Risk adjustment
I77.0 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
I77.0 is named in 25 Medicare coverage policies — 25 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.

How I77.0 is indexed
Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to I77.0.
