Repair of Aneurysm of Arteriovenous Fistula with Endovenectomy
A 51-year-old male with end-stage renal disease (ESRD) presents for repair of an aneurysm of his right brachiocephalic arteriovenous (AV) fistula. A 4 cm incision was made through the subcutaneous tissue; the fistula was exposed, and the aneurysmal section of the fistula was opened with a blade. Heavily calcified rock-like pieces were then removed from the aneurysm, essentially endovenectomizing the lumen. The excess cephalic vein wall was excised, and the edges were plicated with stitches in order to reduce the size and flow of the fistula. What is the correct ICD-10-PCS code(s) for this fistula aneurysm repair? Is the removal of the calcified pieces coded separately? ...

Article Overview
This premium article explains coding considerations for a vascular surgery scenario involving repair of an aneurysmal arteriovenous fistula and related removal of calcified material. It is aimed at medical coders and clinical documentation staff working with inpatient procedural coding, especially ICD-10-PCS assignment in dialysis access cases. The discussion focuses on how to interpret the operative note, distinguish the primary repair from additional procedural components, and determine whether any portion is separately reportable.
Why This Topic Matters
Dialysis access revisions can involve multiple operative steps that are not always represented the same way in coding. Understanding how the procedure is documented helps coders support accurate ICD-10-PCS assignment and avoid missed or duplicate reporting.
