Guide to the Latest CPT Codes for AV Shuntograms: What You Need to Know

If you’re diving into the world of AV shuntograms for dialysis patients, you’re in the right place. Let me tell you, keeping up with the latest CPT codes can feel like chasing a moving target. But don’t worry—I’ve got you covered with a fresh, easy-to-read guide on the current CPT codes for AV shuntogram procedures, straight from the heart of my notes and a recent PowerPoint I came across. Let’s break it down in a way that feels like a chat over coffee, not a lecture hall snooze-fest.

Why AV Shuntograms Matter

Picture this: you’re a patient with chronic kidney failure, and dialysis is your lifeline, happening every two or three days to clean your blood. To make that work long-term, doctors create an arteriovenous (AV) fistula or graft—a kind of superhighway for blood flow. But here’s the catch: the high-speed traffic of blood can cause clogs, like a busy road during rush hour. These blockages, called shunt stenosis or occlusion, can mess up the dialysis process, and if left unchecked, they might force a patient to get a new shunt or rely on temporary catheters. That’s where AV shuntograms come in—they’re like a diagnostic pit stop to figure out what’s wrong and fix it with procedures like unclogging clots or propping open vessels.

The Latest CPT Codes: Your Roadmap to Billing

The American Medical Association (AMA) keeps us on our toes with updated CPT codes, and for AV shuntograms, the codes for 2025 are clear as day. These codes cover everything from the initial diagnostic check to fancy interventions like angioplasty or stenting. Let’s walk through them one by one, so you can code with confidence and avoid any billing headaches.

1. The Diagnostic Starting Line: CPT Code 36901

This is your go-to code for the initial AV shuntogram. It covers sticking a needle or catheter into the dialysis circuit and doing a full diagnostic angiography. Think of it as a full-body scan for the shunt, from the arterial anastomosis (where the artery and vein connect) all the way through the venous outflow, up to the inferior or superior vena cava. It includes all the punctures, catheter placements, contrast injections, fluoroscopic guidance, and a detailed report with images. Basically, it’s the whole shebang for figuring out what’s going on.

2. Fixing the Peripheral Dialysis Segment

Sometimes, the diagnostic shuntogram shows a blockage in the peripheral part of the dialysis circuit. That’s when these codes come into play:

• CPT Code 36902: This builds on 36901 by adding transluminal balloon angioplasty to open up narrowed vessels in the peripheral dialysis segment. It includes all the imaging and radiological supervision needed to make sure the job’s done right.
• CPT Code 36903: If a balloon isn’t enough, this code covers placing intravascular stents in the peripheral dialysis segment to keep things open. It also includes any angioplasty done during the procedure, plus all the imaging and supervision.

3. Clearing Clots with Thrombectomy

When a clot’s gumming up the works, it’s time for a thrombectomy or thrombolysis. These codes have you covered:

• CPT Code 36904: This one’s for percutaneous mechanical thrombectomy (think vacuuming out a clot) or infusing clot-dissolving drugs in the dialysis circuit. It includes all the diagnostic angiography, imaging, fluoroscopic guidance, catheter placements, and any thrombolytic injections during the procedure.
• CPT Code 36905: Same as 36904, but with an added balloon angioplasty in the peripheral dialysis segment to tackle any narrowing.
• CPT Code 36906: This takes it up a notch by including stent placement in the peripheral dialysis segment, along with any angioplasty and all the usual imaging and supervision.

4. Tackling the Central Dialysis Segment

Sometimes, the problem lies deeper in the central dialysis segment, closer to the heart. These are add-on codes, meaning you use them alongside a primary procedure code:

• CPT Code +36907: Covers balloon angioplasty in the central dialysis segment, performed through the dialysis circuit, with all the imaging and supervision needed.
• CPT Code +36908: For when stents are placed in the central dialysis segment, including any angioplasty and all imaging.
• CPT Code +36909: This one’s for permanently blocking off (embolizing or occluding) parts of the dialysis circuit, like accessory veins that are causing trouble. It’s also an add-on code and includes all imaging and supervision.

What’s Happening During an AV Shuntogram?

If you’re new to this, you might be wondering what these procedures actually involve. Here’s the lowdown on the main interventions:

• Thrombectomy: Think of it as unclogging a drain—removing blood clots that block the dialysis circuit.
• Angioplasty: Uses a tiny balloon to stretch open narrowed or blocked vessels, improving blood flow.
• Stent Placement: Places a small mesh tube to keep vessels open, especially in tough spots or after a rupture.
• Embolization: Blocks off collateral veins that might be stealing blood flow and preventing the AV fistula from maturing properly.

These procedures often happen together, depending on what the shuntogram reveals. It’s like a choose-your-own-adventure for fixing dialysis circuits!

Why Getting the Codes Right Is a Big Deal

Messing up CPT codes is like forgetting the punchline to a joke—it just doesn’t land well. Using the right codes ensures hospitals and clinics get paid properly and stay compliant with regulations. Plus, it helps avoid those dreaded audits that make everyone sweat. As a coder, you’ll need to read the procedure notes carefully to pick the right primary code (like 36901 or 36904) and any add-on codes (like 36907–36909) if multiple interventions happen in one go.
