I77.0 vs Z99.2
I77.0 (Arteriovenous fistula, acquired) compared with Z99.2 (Dependence on renal dialysis), from the official CMS tabular data. Do not report these codes together: the official tabular list marks them Excludes1.
Can these codes be reported together?
No — do not report together. I77.0 carries an Excludes1 note covering Z99.2: “presence of arteriovenous shunt (fistula) for dialysis (Z99.2)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
