The CPT code for a CT chest without contrast is 71250. That is the short answer, and if that’s all you needed, there it is. But 71250 sits in a small family of chest CT codes that differ by one thing only, contrast, and the denials on this code almost never come from the scan itself. They come from picking the wrong contrast variant, billing two of them together, mistaking a screening scan for a diagnostic one, or fumbling the professional and technical split. Get those four things right and 71250 is one of the cleaner radiology codes to bill. Get them wrong and it is a reliable source of denied claims.
Here is exactly what 71250 covers, how it differs from 71260 and 71270, what it pays in 2026, when it is the wrong code entirely, and the mistakes that get chest CT claims denied.

What Is CPT Code 71250?
CPT 71250 is a diagnostic CT scan of the thorax, the chest, performed without contrast material. It produces cross sectional images of the lungs, the mediastinum, the chest wall, and the ribs. Physicians order it to work up symptoms and findings, an unexplained or persistent cough, chest trauma, a nodule or abnormality spotted on an x ray, or follow up on a known lung condition. The one detail that defines the code is right there in the name: no IV contrast is given. The scan is a plain, non contrast study of the chest.
That single detail is also the whole billing story. The moment contrast enters the picture, 71250 stops being the right code. So before you bill it, the question is never just what the physician ordered. It’s what the radiology report says was actually performed. The specialties that order chest CTs most, cardiology and pulmonology, see this constantly, which is why our cardiology billing services and pulmonology billing services build the contrast check into every claim.
71250 vs 71260 vs 71270: The Contrast Trio
Three codes cover a diagnostic chest CT, and contrast is the only thing that separates them. Pick the one that matches what was performed.
The rule that catches billers: 71250 and 71260 are mutually exclusive, so you never bill both for the same chest on the same date. When a radiologist acquires a non contrast phase and then a contrast phase in one session, that’s not two codes, it’s one, 71270. The CMS NCCI edits automatically deny a claim that tries to bill 71250 and 71260 together. And here is the principle underneath all of it: the report governs, not the order. If the order said without contrast but the radiologist gave contrast during the exam and documented it, the correct code becomes 71260 or 71270, no matter what the order said.

The Screening Trap: 71250 Is Not for Lung Cancer Screening
This is the mistake that costs the most, because it feels right and it’s wrong. A low dose CT of the chest for lung cancer screening does not use CPT Code 71250. It uses 71271. If you bill 71250 with a screening diagnosis, the claim denies, because the code and the coverage pathway do not match, and that’s true even when the patient is a heavy smoker who clearly qualifies for screening. Screening and diagnostic imaging travel on separate tracks. Keep 71250 for a diagnostic scan ordered because of symptoms or a finding, and use 71271 when the visit is a screening exam. If a document calls the service screening but the claim says 71250, you’ll get a denial.
Modifier 26 vs TC: Splitting the Professional and Technical Parts
CPT Code 71250’s a code with two halves, and who bills which half depends on the setting. The professional component is the radiologist reading and interpreting the images, billed as CPT Code 71250 with modifier 26. The technical component is the scanner, the supplies, and the staff that ran the exam, billed as CPT Code 71250 with modifier TC. When a single entity owns both the equipment and the reading physician, it bills 71250 with no modifier at all, the global service.
The mistake to avoid is a duplicate: the reading physician and the facility both billing globally, or both claiming the same component. Split it cleanly, CPT Code 71250-26 for the interpretation and CPT Code 71250-TC for the scan, so the two claims add up to one whole and never overlap.
What Does CPT Code 71250 Pay in 2026?
Chest CT reimbursement runs on relative value units, and 2026 brought a change that’s worth knowing. The work RVU for 71250 sits at 0.99 after a finalized 2.5 percent efficiency reduction that CMS applied to non time based diagnostic codes, and the total global RVU is 5.66. Multiplied by the 2026 conversion factor of 33.4009 dollars, that produces roughly 57.11 dollars for the professional interpretation and about 131.93 dollars for the technical component. Commercial payers usually pay more, often 120 to 160 percent of Medicare, which puts global commercial reimbursement in the range of 225 to 300 dollars. Confirm your own locality on the CMS physician fee schedule, since geography and the annual RVU update both move the number.
The CPT Code 71250 Denials We Prevent
Almost every CPT Code 71250 denial comes from the same short list. Coding and documentation errors are the leading denial category across healthcare, with industry denial rates between 10 and 15 percent, per 2026 denial benchmarks. Here are the ones that hit chest CT claims.
Two more rules round out clean CPT Code 71250 billing. Medical necessity has to match: the diagnosis on the claim needs to appear on the payer’s supported ICD-10 list for chest CT, or the claim denies even when the scan was appropriate. And for certain advanced imaging, the ordering physician must consult a CMS approved clinical decision support mechanism under PAMA and document it on the claim. When a claim does deny, our denial management services work it back and fix the pattern behind it.
How Docscare Keeps Your Chest CT Claims Clean
We bill radiology the way it actually pays, around the contrast variant, the professional and technical split, and the screening versus diagnostic line, not just a code number. Our AAPC-certified coders read the report for contrast before choosing between CPT Code 71250, 71260, and 71270, keep 71250 off lung cancer screening claims, split the professional and technical components cleanly, and match an ICD-10 that supports medical necessity. When a claim denies, we work it back and fix the root cause.
We’re a US based medical billing company in Austin, Texas, fully HIPAA compliant, running a 99 percent clean claim rate with a 97.45 percent first pass acceptance rate. Radiology runs on high volume and thin per scan margins, so the difference between a clean CPT Code 71250 and one that’s denied, repeated across a busy imaging schedule, is real money. See how it fits into our full medical billing services.

Frequently Asked Questions
What is CPT code 71250?
CPT 71250 is the code for a diagnostic CT scan of the thorax, the chest, performed without contrast material. It captures the lungs, mediastinum, chest wall, and ribs in cross section, and it is used to evaluate symptoms like an unexplained cough, chest trauma, a suspicious finding on an x ray, or a known lung condition. The defining feature is that no IV contrast is given. The moment contrast is administered, CPT Code 71250 is no longer the correct code.
What is the CPT code for a CT chest without contrast?
The CPT code for a CT chest without contrast is 71250. If contrast is given, the code changes: 71260 covers a CT chest with contrast only, and 71270 covers a CT chest done without contrast and then with contrast in the same session. Pick the code that matches what the radiology report says was actually performed, not what was originally ordered.
What is the difference between CPT Code 71250, 71260, and 71270?
All three are CT scans of the chest, and contrast is the only difference. CPT Code 71250 is without contrast. 71260 is with contrast only. 71270 is without contrast followed by with contrast in a single session. They are mutually exclusive, so you never bill CPT Code 71250 and 71260 together for the same chest on the same day. When both a non contrast and a contrast phase are performed in one session, you bill 71270 by itself.
Is CPT Code 71250 used for lung cancer screening?
No, and this is a common and costly mistake. Lung cancer screening with a low dose CT uses 71271, not 71250. If you bill CPT Code 71250 with a screening diagnosis, the claim denies because the code and the coverage pathway do not match, even when the patient has smoking risk factors. Keep CPT Code 71250 for diagnostic scans ordered because of symptoms or findings, and use 71271 for a screening exam.
Does CPT Code 71250 use modifier 26 or TC?
It depends on who is billing and for what. CPT Code 71250 splits into two parts. The radiologist who reads and interprets the scan bills CPT Code 71250 with modifier 26, the professional component. The facility that owns the scanner and provides the staff bills 71250 with modifier TC, the technical component. If one entity performs both parts, it bills 71250 with no modifier, the global service. The rule is that both parties must never bill for the same component.
