CPT code 75572: Cardiac CT billing and reimbursement

CPT code 75572 bills a contrast-enhanced CT of the heart performed to evaluate cardiac structure and morphology.

One detail drives most of its denials. 3D image postprocessing and cardiac function assessment are already bundled into the code, so billing either one separately is unbundling. The other recurring problem is its neighbor 75574, which covers coronary CTA and pays more.

Get the choice wrong and the claim comes back denied, or the payment gets pulled back on audit. The rest of this page works through the money, the diagnoses, the modifiers, and the paperwork that keeps 75572 paid.

Key takeaways

CPT code 75572 covers cardiac CT with contrast for structure and morphology, not coronary artery CTA, which is 75574.

3D image postprocessing and cardiac function assessment are bundled into 75572 and cannot go on a separate claim line.

Medicare pays roughly $229 nationally for the global service, about $149 for the technical component and about $80 for the read.

Coverage rests on a supported ICD-10 diagnosis and a report that addresses every element named in the descriptor.

Many commercial plans require prior authorization for 75572, while Medicare reviews medical necessity after payment instead.

What CPT code 75572 covers, and what it bundles in

CPT code 75572 describes computed tomography of the heart with contrast material, performed to evaluate cardiac structure and morphology.

The descriptor then names three services that travel with it. Those are 3D image postprocessing, assessment of cardiac function, and evaluation of venous structures where performed. All three are bundled into the one code.

Put 3D postprocessing on its own line next to 75572 and you have unbundled the code. The American Medical Association’s CPT code set uses inclusive parenthetical language to signal the bundling.

Payers then enforce it with National Correct Coding Initiative (NCCI) edits, so the extra line simply denies.

Where 75572 sits in the cardiac CT family

The cardiac CT family runs from 75571 through 75580, and each code answers a different clinical question. Reading the set together is the quickest way to stop picking the wrong sibling, which is the fastest route to an audit.

The 75572 and 75574 mix-up is the common one. 75572 is a single-source CT of overall cardiac structure, so chambers, valves and morphology. CPT 75574 is what most cardiologists mean when they say cardiac CTA.

Billing 75572 for a coronary study undercodes the work, while billing the coronary code for a morphology-only study overcodes it. Either direction creates audit exposure.

What Medicare actually pays for 75572

Medicare pays roughly $229 for a global 75572 at the national unadjusted rate. Split the service and the professional read comes to about $80, while the technical component takes about $149.

The code carries 1.71 work RVUs and 6.87 total RVUs. All of these figures come from the CMS Physician Fee Schedule.

The spread between the three arrangements is what makes the modifier worth settling early.

Geographic adjusters move these numbers by roughly 15% to 25% either side of the national base. Pull your own locality rate from the CMS fee schedule lookup tool before you quote a patient or reprice the chargemaster.

When Medicare covers a cardiac CT

Medicare coverage for 75572 sits under CMS article A56691, “Billing and Coding: Cardiac Computed Tomography & Angiography (CCTA)”. Coverage is never automatic.

The claim has to carry a medically necessary indication, and the record has to demonstrate it. A non-covered use will deny however cleanly the rest of the claim is built.

Indications payers accept

• Suspected or known coronary artery disease where other non-invasive testing came back inconclusive
• Assessment of cardiac structural anomalies, including chambers, valves and pericardium, when echocardiography is technically limited
• Pre-procedural planning for cardiac interventions that need anatomical detail
• Evaluation of cardiac masses, thrombus or pericardial effusion
• Follow-up of known congenital cardiac abnormalities in adults, where 75573 does not apply

Indications that get denied

• Routine cardiac screening in asymptomatic, low-risk patients
• Repeat studies with no documented clinical change or new indication
• Studies ordered purely for medicolegal documentation, with no clinical necessity
• Cases where echocardiography would answer the same clinical question for less

Coverage criteria still vary by Medicare Administrative Contractor (MAC). Check your own MAC’s Local Coverage Determination before you submit a borderline case, because the national article is only the starting point.

Pair 75572 with a diagnosis that supports it

Every 75572 claim needs an ICD-10 diagnosis that supports medical necessity. An unsupported diagnosis is the second biggest denial driver, behind missing prior authorization. The pairings below are the ones payers accept most often under CMS coverage criteria.

That last row is in the table as a warning. A history code from another body system carries no cardiac information, so it will not support the claim on its own.

The modifier depends on who owns the scanner

Modifier choice on 75572 comes down to two questions. Who owns the scanner, and who reads the study? Answer both at charge capture and the modifier settles itself. Answer them in the billing office a week later and you are reconstructing the facts from memory.

Never put modifier 26 and TC on the same claim line for the same provider. That pairing reads as a billing system fault and triggers an automatic review.

Build the interpretation report around the descriptor

The report has to address every component the descriptor names. Payers read the report against the descriptor during medical necessity review, so a missing element becomes a missing payment.

Required elements in the interpretation report

• Clinical indication: the referring diagnosis or symptom that makes the study medically necessary
• Cardiac structure and morphology: a description of chambers, walls, valves and pericardium
• 3D postprocessing performed: a statement confirming the reconstruction was done, even where the findings are normal
• Cardiac function assessment: ejection fraction and wall motion findings, or a note explaining why assessment did not apply
• Venous structures: evaluation of pulmonary or cardiac veins if performed, or a note that it was not clinically indicated
• Contrast administration: the agent used, the volume and the route
• Ordering physician: the name and NPI of the referring provider

Store the report with the order and the clinical notes so the billing file stands on its own. When a post-payment audit lands 18 months later, that file is what answers it.

Prior authorization is a commercial payer problem

Many commercial plans require prior authorization for 75572. Medicare does not, and reviews medical necessity after the fact instead.

The difference changes how you triage the work. Skipping prior auth with a commercial payer guarantees a denial, while a thin Medicare file is a recoverable audit finding.

How the commercial authorization process runs

EviCore Healthcare handles cardiac imaging authorization for many large commercial insurers. Their portal asks for the referring diagnosis, the clinical history, any prior cardiac workup and the CPT code you want approved. Standard requests usually clear in two to five business days, and expedited clinical reviews in 24 to 48 hours.

• Check whether the patient’s plan uses EviCore or an in-house authorization team before you send the request
• Document the failed or inconclusive prior workup, such as a stress test or echocardiography, to support the request
• Record the authorization number and attach it to the claim at submission
• Note the expiration date, because an expired authorization number is treated as no authorization at all

From order to payment, step by step

It helps to see where a cardiac CT claim can stall before it gets there. Six handoffs sit between the order and the payment, and each one has its own failure mode.

1. Order and indication. The referring physician records why the scan is needed, and that wording becomes the diagnosis on the claim.
2. Eligibility and authorization. The front desk confirms the plan, checks whether the scan needs authorization, and files the number with its expiry date.
3. Scan and read. The technologist acquires the study with contrast, then the physician interprets it and signs the report.
4. Charge capture. Somebody picks global, 26 or TC here. This is the cheapest place in the whole process to get the modifier right.
5. Scrub and submit. The claim leaves as an 837 file carrying 75572, the supporting ICD-10 code, the modifier and the authorization number.
6. Remittance. The payer returns payment or a denial code, and an unpaid line drops into the follow-up queue.

Steps two and four cause most of the rework. Both happen before anyone in billing touches the claim, which is exactly why denial rates on cardiac imaging rarely improve by working the queue harder.

Five denials that keep coming back

Denials on 75572 cluster around five causes, and every one of them is preventable at the front end.

Each denial arrives with a reason code, and reading it correctly decides whether you correct and resubmit or start an appeal. The guide to medical billing denial codes sets out what the common ones mean.

A checklist to run before you submit

• The report names 3D postprocessing, cardiac function and venous structures, or says why one did not apply
• The diagnosis on the claim matches the indication in the order and sits on your MAC’s covered list
• The modifier matches who owns the scanner, and 26 and TC are not on the same line
• The authorization number is on the claim and has not expired
• No separate 3D rendering code shares a claim with 75572
• The referring provider’s name and NPI are on the order

What changed for 2026: CPT 75577 and 75580

The AMA’s CPT Editorial Panel creates and issues CPT codes. The genuinely new code in this corner of cardiac imaging is CPT 75577, a Category I code effective January 1, 2026.

It covers software quantification and characterization of coronary atherosclerotic plaque. It replaced Category III codes 0623T to 0626T, which had been in use since January 1, 2021.

• CPT 75577 reports quantitative analysis and characterization of coronary atherosclerotic plaque, both fatty and calcified, from CCTA data already acquired. Interpretation and report by a physician or other qualified health care professional are included.
• 75577 is reported once per coronary CTA, and in addition to 75574 rather than instead of it. It does not cover interpretation of the coronary CTA itself.
• CPT 75580 is a different service and is not new. It reports a noninvasive estimate of coronary fractional flow reserve, derived by augmentative software from the CCTA data set. It became a Category I code on January 1, 2024, replacing Category III codes 0501T to 0504T.
• The CPT parenthetical instruction is explicit. Use 75580 in conjunction with 75574 when both are performed on the same day, and report it once per coronary CTA.
• CPT code 75572 is unaffected by either one. It covers cardiac structure and morphology, not coronary plaque burden and not coronary flow.
• Confirm the current descriptors and parenthetical instructions against the AMA CPT 2026 code set, or a current CPT code reference. Do that before you update your charge description master.

Practices billing 75572 and 75574 should carry 75577 and 75580 as separate line items in the chargemaster. Neither substitutes for the coronary CTA code, and coverage for both still varies by payer, so check each policy before you bill.

The documentation needs to show which software was used, what it produced, and that a physician interpreted the output and signed a report.

How Pabau keeps cardiac imaging claims clean

Most of the failures above happen long before anyone opens the claim form. The order says one thing and the report says another, or the authorization number sits in an email nobody can find at submission.

Practice management software like Pabau keeps those pieces on one patient record. Its claims management software pulls the CPT code attached to the service straight onto the charge line.

The ICD-10 slots are seeded from the patient’s recorded problem list. Searchable ICD-10 and CPT libraries sit beside the form, so a coder checks a descriptor without opening a second tab.

Submission stays locked until the claim’s required fields are complete. A missing membership or authorization number therefore stops the claim at your desk rather than at the payer.

In the US, claims route through our Claim.MD integration, so eligibility checks, claim status and electronic remittance come back into the same record. Your billing team can follow a 75572 from charge capture to payment posting without leaving the patient file.

Keep cardiac imaging claims moving

Pabau builds the claim from the patient record, holds it until every required field is complete, and tracks status and remittance in one place. Your team spends less time rebuilding claims that should have gone out right the first time.

Conclusion

75572 rewards precision at the front of the process. The descriptor bundles more than it looks like it does, and the neighboring coronary code pays differently. Coverage then rests on a diagnosis somebody else wrote into the order.

Three habits close most of the denials in this article. Fix the modifier at charge capture, check the diagnosis against your MAC’s list, and make the report answer the descriptor line by line. All three cost less than appealing the same denial every month.
