About I77.0

I77.0 is the ICD-10-CM diagnosis code for arteriovenous fistula, acquired. It belongs to category I77 (other disorders of arteries and arterioles), block I70-I79 (diseases of arteries, arterioles and capillaries) and chapter 9 (diseases of the circulatory system). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within I77 (other disorders of arteries and arterioles), I77.0 is specifically for arteriovenous fistula, acquired. Related codes cover stricture of artery (I77.1), rupture of artery (I77.2), arterial fibromuscular dysplasia (I77.3), celiac artery compression syndrome (I77.4), necrosis of artery (I77.5), arteritis, unspecified (I77.6), other arterial dissection (I77.7), other specified disorders of arteries and arterioles (I77.8) and 1 more.

Don't report I77.0 together with the conditions in its Excludes1 note: arteriovenous aneurysm NOS (Q27.3-), presence of arteriovenous shunt (fistula) for dialysis (Z99.2) and traumatic - see injury of blood vessel by body region.

The conditions in its Excludes2 note aren't part of I77.0, but may be coded alongside it if the patient has both: cerebral (I67.1) and coronary (I25.4).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 299 (Peripheral Vascular Disorders with MCC, relative weight 1.5842), DRG 300 (Peripheral Vascular Disorders with CC, relative weight 1.0464) and DRG 301 (Peripheral Vascular Disorders without CC/MCC, relative weight 0.7133), in MDC 05 (Diseases and Disorders of the Circulatory System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 447.0 (arteriovenous fistula, acquired).
