Radiology CPT Codes: The Real Guide to Survival and Payment in 2026

If you have been in the healthcare revenue game as long as I have, you know that January 1st isn’t just a new year; it is usually a massive headache. Every single year, the American Medical Association (AMA) shakes up the basket of Radiology CPT Codes, and 2026 is shaping up to be one of the most volatile years I’ve seen in decades.

Navigating the complex landscape of Radiology CPT Codes is critical for maintaining a healthy revenue cycle this year. We aren’t just talking about swapping out a few numbers here. We are looking at a massive overhaul of interventional coding (specifically lower extremity revascularization), a complete restructuring of prostate biopsies, and a “give-and-take” financial landscape. If you aren’t paying close attention to these specific Radiology CPT Codes, your practice is effectively volunteering to work for free.

This article isn’t just a list; it’s a breakdown of how to keep your doors open. We are going to dig into the new Radiology CPT Codes for 2026, pinpoint where the hidden revenue is, and explain exactly how to stop denials from eating your profits alive.

The 2026 Financial Reality: Why Radiology CPT Codes Matter More Now

Let’s get the hard numbers out of the way. On the surface, the news looks decent. The 2026 Medicare Conversion Factor has actually increased slightly to roughly $33.40 (for non-APM participants), up from last year’s lows.

But do not pop the champagne yet.

While the base rate is up, CMS has finalized a -2.5% “Efficiency Adjustment” for non-time-based codes. Since almost all diagnostic Radiology CPT Codes (like X-rays, CTs, and MRIs) are “non-time-based,” this adjustment effectively wipes out the conversion factor gain for imaging. You are likely breaking even or seeing a slight dip compared to 2025, especially when you factor in inflation.

This is why accuracy with Radiology CPT Codes is your only defense. You cannot control the federal fee schedule, but you can control your denial rate. Right now, a single denied claim costs about $25 to $30 to rework. In 2026, you cannot afford that waste.

The Massive LER Overhaul in Radiology CPT Codes

If you do any vascular interventional work, stop what you are doing and read this section twice. The old Radiology CPT Codes for leg revascularization (37220–37235) are gone. Deleted. History.

In their place, the AMA has released a massive block of 46 new Radiology CPT Codes (37254–37299). This is the biggest change to interventional radiology CPT codes in a generation.

The New “Territory” System

The new codes are organized by “vascular territory” rather than just the vessel. You must now assign Radiology CPT Codes based on where the work happened:

Iliac Territory

Femoral/Popliteal Territory

Tibial/Peroneal Territory

If your interventionalists are still documenting “fixed the leg,” you will get zero payment. They must specify the territory so you can select the accurate Radiology CPT Codes.

Diagnostic Radiology CPT Codes: Bundling & Brains

The 2026 updates for diagnostic imaging are all about streamlining—which is usually code for “bundling.”

The New CTA Head & Neck Bundle

In the past, we often juggled separate Radiology CPT Codes for CTA Head and CTA Neck. For 2026, we have a new workhorse code: 70471.

70471: Computed Tomography Angiography (CTA) of the Head and Neck.

Includes: Contrast, non-contrast spins (if performed), and all post-processing.

The Trap: Do not try to bill post-processing (3D rendering) separately. It is now built-in to these Radiology CPT Codes.

Stroke Care: CT Perfusion Goes Mainstream

For years, CT Cerebral Perfusion (CTP) languished with temporary “Category III” codes. In 2026, it finally graduates to Category I status, joining the permanent list of Radiology CPT Codes.

70473: CT Cerebral Perfusion (billed alone).

+70472: CT Cerebral Perfusion (billed as an add-on to a CTA or CT Head).

This is a huge win for stroke centers. Ensure your chargemaster is updated to trigger +70472 automatically when a stroke protocol CTA is ordered to capture this revenue using the correct Radiology CPT Codes.

Prostate Biopsy: The End of “55700”

For decades, 55700 was the go-to among Radiology CPT Codes for a prostate biopsy. In 2026, it has been deleted.

We now have a family of codes (55707–55714) that requires you to specify the approach:

Transperineal

Transrectal

You must also document the type of imaging guidance used. If your urologist or radiologist just writes “biopsy performed,” the claim will be rejected because you cannot identify the specific Radiology CPT Codes required.

AI Finally Has a Seat at the Table

2026 is the year AI stops being a buzzword and starts being a billable service in radiology. New Radiology CPT Codes have been introduced for AI-based analysis, specifically for Coronary Plaque Analysis.

These codes (Category I) allow you to bill for the AI analysis of cardiac CT angiography to quantify plaque. This is a potential new revenue stream, but only if your software outputs the specific data points required by the descriptor of these new Radiology CPT Codes.

Common Pitfalls That Will Kill Revenue in 2026

Knowing the new Radiology CPT Codes is only half the battle. The other half is execution. In my 25 years in this business, I have seen the same mistakes happen over and over again.

The “Medical Necessity” Trap

A common pitfall with Radiology CPT Codes is the mismatch between the exam ordered and the diagnosis provided. For example, billing the new 70471 (CTA Head/Neck) for a vague “dizziness” diagnosis might trigger a denial if your payer’s LCD (Local Coverage Determination) requires more specific signs of vascular disease to justify these Radiology CPT Codes.

Modifier Mastery

Modifiers are the traffic signals of billing. They tell the payer exactly how to process a specific CPT code for radiology.

-26 Modifier: The doctor’s fee.

-TC Modifier: The facility’s fee.

-59 / -X{EPSU} Modifiers: The most audited modifiers. With the new LER Radiology CPT Codes, using -59 to try and unbundle territories that are technically adjacent is a surefire way to get audited.

How to Fix Your Workflow for 2026

So, how do you actually implement these changes without bringing your office to a standstill? It comes down to three things: Software, Training, and Partners who understand Radiology CPT Codes.

Update Your Charge Master Immediately

If your billing software hasn’t been updated with the 2026 Radiology CPT Codes (especially the 46 new vascular codes), you are dead in the water. I know a practice that didn’t update their system until February one year. They had six weeks of claims for “deleted codes” pile up. It took them six months to clean up the mess caused by outdated Radiology CPT Codes.

Talk to Your Techs

Billing doesn’t start in the back office; it starts in the exam room. Your technologists need to know that their notes now directly impact revenue. For the new MRI Safety Radiology CPT Codes (which are fully mature in 2026), if they don’t log the start and stop time of the safety assessment, you cannot bill it.

The Cost of Getting It Wrong

Let’s be real about the money. We are operating on razor-thin margins. A single MRI reimbursement might be a few hundred dollars. If you have to pay a biller to work on that claim three times, you have lost your profit margin.

When you look at interventional radiology CPT codes, the stakes are even higher. These are high-dollar procedures. A denial on a complex embolization or ablation can hold up thousands of dollars for months, simply because the wrong Radiology CPT Codes were selected.

Why Outsourcing Might Be Your Best Move

Look, keeping up with Radiology CPT Codes is a full-time job. And I don’t mean a “part of the office manager’s job.” I mean it requires someone who reads the AMA updates for fun.

Most small to mid-sized practices just don’t have the resources to train their staff on every single update that drops in January. And honestly, why should you? Your focus should be on patient care and reading images, not fighting with insurance companies over whether a tibial vessel code allows for an add-on or if you used the right Radiology CPT Codes.

This is where specialized help comes in. General billing companies often mess up radiology. They don’t know the difference between a view and a sequence. They don’t understand that the new 37254 code requires distinct territory documentation. You need experts who speak the language of Radiology CPT Codes.

We have spent years refining our process to catch these errors before they leave the building. We know exactly what triggers an audit and what ensures a clean claim using the proper Radiology CPT Codes.

If you are tired of seeing your revenue dip every time the rules change, or if you just want to stop worrying about compliance and start focusing on growth, we should talk.

Our medical billing services are built by experts who have been in the trenches. We handle the complexity of the 2026 updates so you get paid every dollar you earned, on time, the first time.
