[Resident/PA name]
Local: [X] mL 1% lidocaine without epinephrine [/ regional brachial plexus block / MAC]
The patient is a [age]-year-old [male / female] with end-stage renal disease requiring permanent hemodialysis access. Pre-operative vein mapping demonstrated [cephalic / basilic] vein diameter of [X mm] and [radial / brachial] artery inflow. A [radiocephalic / brachiocephalic / brachiobasilic] AVF was selected. The risks, benefits, and alternatives including AV graft were discussed and informed consent was obtained.
The [cephalic / basilic] vein was identified and mobilized with adequate diameter [X mm] and quality. The [radial / brachial] artery was well-pulsatile. The anastomosis was constructed without tension. A thrill was palpable and bruit auscultated throughout the [forearm / upper arm] fistula upon completion. Doppler confirmed flow.
The patient was positioned supine with the ipsilateral arm extended on an arm board. The [wrist / antecubital fossa] was prepped and draped. Local anesthesia was infiltrated.
A longitudinal incision was made over the [radial artery at the wrist / brachial artery at the antecubital fossa]. The [cephalic / basilic] vein was identified, mobilized for [2-4] cm, and branches ligated. The artery was dissected and controlled. Before clamping, [the patient was systemically heparinized / the vessel lumens were irrigated with heparinized saline].
The vein was spatulated to match the arteriotomy. A longitudinal arteriotomy [approximately 6-8 mm] was made and the lumens irrigated with heparinized saline. The end-to-side anastomosis was constructed using running [6-0 Prolene] suture. Clamps were released. A thrill was immediately palpable and a bruit audible throughout the fistula. Doppler confirmed flow.
The wound was closed in layers. A light dressing [not circumferentially compressive] was applied.

The patient tolerated the procedure well. A thrill was confirmed at the anastomosis. The patient was instructed on fistula care and to return for fistula maturation assessment in [6-8 weeks]. Cannulation should not occur until documented maturation is confirmed at the 6-8 week assessment.

AV Graft (Prosthetic, Vein Unsuitable)
Given inadequate vein caliber [<2.5 mm] on pre-operative mapping, a prosthetic AV graft was used. A [6 mm] ePTFE loop graft was tunneled in the [forearm / upper arm] in a [loop / straight] configuration. Proximal anastomosis was constructed end-to-side to the [brachial / radial] artery and distal anastomosis end-to-side to the [brachiobasilic / antecubital] vein. Thrill was confirmed throughout the graft. AV grafts can be cannulated earlier than AVF (2-3 weeks) but have lower long-term patency.
Brachiobasilic AVF with Transposition
The basilic vein in the medial upper arm was exposed through a longitudinal incision, mobilized from elbow to axilla, ligated and divided distally. The vein was transposed through a subcutaneous tunnel to the lateral arm surface to allow dialysis cannulation access. The proximal end was anastomosed end-to-side to the brachial artery. Thrill confirmed throughout. A two-stage approach (Stage 1: brachio-basilic anastomosis without transposition; Stage 2: superficialization at 6 weeks) may be preferred for small-diameter basilic veins to allow maturation before transposition.
Charting Tips
- Document that a thrill is palpable and bruit is audible at the end of the case. Absent thrill immediately post-operatively indicates technical failure and should prompt intraoperative revision rather than post-operative discovery.
- Maturation measurements: Record vein diameter and artery caliber from pre-operative duplex mapping. The rule of 6s for AVF maturation includes:
- Vein diameter ≥6 mm
- Depth ≤6 mm from the skin
- Straight segment ≥6 cm long
- Flow >600 mL/min
Document pre-operative measurements to establish expected maturation potential.
- Document the no-compression dressing instruction and timeline for fistula use. Premature cannulation and inadvertent compression are the two most preventable causes of early fistula failure.
- ICD-10: N18.6 (ESRD) is the primary code; Z99.2 (dependence on renal dialysis) is coded as an additional code when the patient is already receiving dialysis. Both are required for CMS ESRD quality metric reporting.
Documentation & Reimbursement Considerations
- Primary service: Report Arteriovenous Fistula Creation (Hemodialysis Access) as the primary service when it is the definitive operation performed.
- Transposition procedures use different codes.
- Document graft material (ePTFE, bovine carotid artery/Artegraft, early-cannulation graft/Gore Acuseal) and configuration (loop vs. straight). Dacron is not used for dialysis access grafts.
- Global period is 90 days. Post-op fistula mapping, ultrasound surveillance, and routine follow-up within 90 days are bundled. Fistulogram and angioplasty for stenosis are separately billable with staged-or-related-procedure reporting (planned staged procedure within global) or unrelated-procedure reporting during the postoperative period (unrelated procedure after global). Use related unplanned return-to-the-operating-room reporting only for unplanned return to OR for a complication.
- ESRD Network reporting: for Medicare patients on dialysis, document that the patient has ESRD and this is a dialysis access creation. This is required for CMS ESRD quality metrics.
- Ligation of side branches (accessory vein coil or ligation) performed at the same session is bundled. Do not bill separately.
- Document: vessel selected (radial/brachial artery, cephalic/basilic vein), whether transposition was performed, anastomosis configuration (end-to-side), venous diameter on pre-op mapping, thrill/bruit and Doppler confirmation at end of case, and estimated maturation timeline.
