Q27.3 vs Q27.8
Q27.3 (Arteriovenous malformation (peripheral)) compared with Q27.8 (Other specified congenital malformations of peripheral vascular system), 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. Q27.8 carries an Excludes1 note covering Q27.3: “arteriovenous malformation (Q27.3-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
