CPT 75574: 2026 CCTA Coding, Billing and Reimbursement Guide

Medical coding disclaimer: This article is general educational information for cardiology, radiology, and revenue-cycle professionals. It is not coding, billing, legal, or reimbursement advice for any specific claim, patient, or payer contract. CPT codes, descriptions, and related data are copyright the American Medical Association (AMA); CPT is a registered trademark of the AMA. Always verify current code definitions, National Correct Coding Initiative (NCCI) edits, and payer or Medicare Administrative Contractor (MAC) policy before submitting a claim.

CPT 75574 is the code for coronary CT angiography, or CCTA. It reports a contrast-enhanced CT exam of the heart, the coronary arteries, and bypass grafts when they’re present, and it includes 3D image postprocessing. Correct payment doesn’t come from the code definition alone. It depends on choosing the right code, documenting medical necessity, and meeting each payer’s specific requirements.

The definition of CPT code 75574 isn’t where practices lose money. The risk sits around it: confusion with the other cardiac CT codes, same-day bundling errors, incorrect use of the professional and technical components, missing prior authorization, thin medical-necessity documentation, and a final report that skips a required element. Any one of those turns a clean scan into a denied claim, and most of them are preventable at the point the claim is built, not after a payer rejects it.

This guide from ONE O SEVEN RCM walks through which code applies to a given study, what’s bundled into 75574, how to use modifiers 26 and TC correctly, which 2026 changes matter for cardiology and radiology groups, what the documentation needs to include, and how to keep denials from eating into collections on coronary CTA claims.

What Changed for CPT 75574 in 2026?

The main 2026 developments for CPT 75574 are a new CMS audit focus, an updated NCCI manual, a provisional hospital outpatient payment classification, and a new code for coronary plaque assessment. The underlying coronary CTA code hasn’t changed. What changed is the coding, documentation, and reimbursement environment around it, and providers billing 2026 dates of service need to account for all four.

CMS RAC Review Targets CPT 75574

CMS approved a Recovery Audit Contractor topic on August 28, 2025, that names 75574 directly. The review applies to outpatient hospitals, and it applies across every A/B MAC jurisdiction in the country, not just one region. Reviewers under this topic look at whether the documentation on file supports Medicare coverage criteria, current coding guidance, and medical necessity for the CCTA billed. CMS lists CPT 75574 as the affected code in its approved outpatient hospital RAC topic on CT coronary angiography medical necessity and documentation requirements. A hospital that hasn’t tightened its CCTA chart before this review reaches its claims is taking on unnecessary risk.

2026 NCCI Rules Apply to Radiology Claims

The 2026 National Correct Coding Initiative Policy Manual took effect January 1, 2026, and cardiac CT services fall inside its radiology chapter. Coders and billers should pull the current version rather than lean on a summary written for a prior year, since bundling edits get revised annually and a stale reference can cost a clean claim. CMS publishes the current 2026 Medicare NCCI Manual with an effective date of January 1, 2026, for exactly this reason.

Additional 2026 Developments to Watch

The American College of Cardiology confirms that the new code replaced the deleted Category III plaque-analysis codes as of January 1, 2026. The American College of Radiology confirms that cardiac CT codes 75572 through 75574 stay in APC 5572 for 2026, but only on a provisional basis.

What Does CPT 75574 Include?

CPT 75574 reports coronary CT angiography: a contrast-enhanced CT study of the heart built around the coronary arteries, with bypass graft evaluation included when grafts are present and imaged. The code also includes 3D image postprocessing, and it covers additional structural, functional, and venous assessment when those elements are actually performed and documented. The Society of Cardiovascular Computed Tomography lists 75574 as coronary CT angiography of the heart, coronary arteries, and bypass grafts when present, with contrast and included 3D postprocessing.

The 75574 CPT code description centers on coronary angiography, not a general CT examination of the chest. Coders searching for the CT angio coronary CPT code, or looking up the 75574 CPT code, are usually trying to confirm whether a cardiac CT study qualifies as a coronary CTA scan or belongs under a related code instead. That distinction, not the department or scanner that ran the study, is what a CCTA scan is coded against.

Core Service Elements

The coronary arteries are the primary target. CPT code 75574 exists to evaluate coronary anatomy and suspected or known coronary artery disease, and that’s the anatomical focus a coder should confirm before assigning the code. Bypass graft evaluation is part of the same code when grafts exist and get imaged as part of the study, but not every patient has grafts, and a coder shouldn’t assume graft evaluation belongs on every claim.

Contrast material is part of what defines this service. It’s a contrast study, which is one of the fastest ways to tell it apart from CPT 75571, the noncontrast calcium-scoring code. Three-dimensional postprocessing is also built into 75574. It shouldn’t generate an automatic separate charge, since the code already accounts for that work.

Beyond the coronary arteries, the descriptor allows for cardiac structure and morphology, cardiac function, and venous structures to be assessed “if performed.” That phrase matters for documentation. A report doesn’t need every optional element to support the claim, but whatever the report does include should match what actually happened during the study.

What the Code Does Not Mean

This code is not a general chest CTA, a standalone calcium-score study, a non-coronary structural cardiac CT, or a congenital cardiac CT code. It’s also not a guarantee of payer coverage, and it doesn’t guarantee that every associated analysis performed alongside it is separately payable. A coder who treats 75574 as a blanket “heart CT” label, rather than the coronary-specific study it actually describes, is the coder most likely to pick the wrong option from the cardiac CT family. A coronary CTA is defined by its target first and its equipment second.

When Is Coronary CTA Clinically Appropriate?

Coronary CTA, also called cardiac CTA or CTCA depending on the reference, fits a defined set of clinical scenarios: selected patients with stable chest pain, selected acute chest-pain presentations, suspected coronary artery disease, suspected coronary anomalies, evaluation of bypass grafts, and preprocedural coronary assessment in appropriate cases. CPT 75574 isn’t the automatic first test for every patient who reports chest pain, and documentation should reflect the actual clinical question, not a generic complaint.

Stable Chest Pain Evaluation

Current multisociety chest pain guideline supports a CCTA scan within specific diagnostic pathways for stable chest pain, shaped by the patient’s risk, symptoms, prior testing, age, and known coronary disease. The ordering note should state the actual reason for the exam rather than a generic chest-pain complaint, because that reason is what a reviewer checks first against the final report and the diagnosis on the claim.

Acute Chest Pain and Emergency Evaluation

CCTA can be considered in selected acute presentations, but the record needs to show the specific clinical presentation and why coronary evaluation, rather than another pathway, was the right next step. An emergency department visit by itself isn’t documentation of medical necessity. The chart still needs to connect the presenting symptoms to the decision to order a CCTA.

Known CAD, Bypass Grafts, and Coronary Anomalies

Several distinct clinical questions fall under this same code: graft patency in a patient with a surgical history, coronary anatomy in a patient with known disease, a suspected congenital coronary anomaly, or further evaluation after an inconclusive prior test. Each of these supports a different note in the chart, and the report should make clear which question the study was ordered to answer.

When the Service Becomes High Risk for Denial

A handful of patterns raise denial risk on CCTA claims: asymptomatic screening, a vague “rule out CAD” order with no supporting context, no documented clinical question at all, a code chosen based on what the scanner can do rather than what the report describes, and a mismatch between the order, the report, the diagnosis, and the claim. None of this means a diagnosis like R07.9 is automatically non-covered. It means the diagnosis has to accurately reflect the medical record and the applicable payer policy, not the other way around.

Specialty medical billing teams should compare the order, clinical indication, final report, code selection, and payer policy before a CCTA claim goes out the door. ONE O SEVEN RCM applies specialty medical billing and payer review to cardiology and diagnostic-imaging claims before submission.

CPT 75574 Compared With Related Cardiac and Chest CT Codes

The correct cardiac CT code depends on the documented service and anatomical target, not on which scanner performed the study. CPT 75574 applies when the exam evaluates the coronary arteries and bypass grafts when present. CPT 75572 covers non-coronary cardiac structure and morphology. CPT 75571 reports standalone coronary calcium scoring. Mixing these up is one of the most common ways a cardiac CT claim gets coded wrong.

SCCT’s current code list separates 75572 as structural and morphological cardiac CT, 75573 as congenital cardiac CT, and 75574 as CCTA.

CPT 75572 vs CPT 75574

CPT 75572 is non-coronary structural cardiac CT. CPT 75574 is coronary CTA. Both use contrast, and both can include specified cardiac and venous assessments when those elements are performed. The documented anatomical target, not the scanner or the department that ran the study, decides which one applies. CPT 75572 isn’t limited to the coronary arteries in the way some coders assume; it’s built around structure and morphology, and a report that discusses chamber size, wall motion, or valve anatomy without a coronary artery finding is usually a 75572 study, not a CCTA.

CPT 75571 vs CPT 75574

CPT 75571 is noncontrast, standalone calcium scoring. CPT 75574 is a contrast coronary CTA, and that contrast requirement is the fastest way to tell the two apart on a chart. When calcium scoring happens in the same session as a CCTA, it’s handled under the bundling rules covered in the next section, not billed as two separate line items by default. Treating 75571 as an add-on to a contrast study is one of the most common cardiac CT coding errors.

CPT 75573 vs CPT 75574

CPT 75573 covers congenital cardiac structure and morphology. CPT 75574 centers on coronary artery imaging. A congenital diagnosis on the chart doesn’t automatically mean 75573 is the right code; the actual exam performed and the final report are what decide code selection, the same as with any other cardiac CT choice. A patient with a known congenital condition can still receive a CCTA if that’s what the ordering physician actually requested and the report actually documents.

CPT 71275 vs CPT 75574

CPT 71275 reports CTA of the chest. CPT 75574 reports coronary CTA. They shouldn’t be treated as interchangeable just because both involve contrast and CT angiography. What matters is the documented vascular target and what the completed exam actually evaluated. A chest CTA ordered to rule out a pulmonary or aortic finding doesn’t become a CCTA claim just because the heart appears somewhere in the field of view.

Coronary CTA vs Calcium Score

However a coder arrives at this page, whether searching CPT code 75574, the 75574 CPT code, the CCTA CPT code, the Coronary CTA CPT code, or the Cardiac CTA CPT code, the answer sits in the same place: one code, distinguished from its neighbors by the coronary artery and bypass graft target described above, not by the equipment that produced the images.

What Is Bundled Into CPT 75574?

This code includes contrast coronary CTA, 3D image postprocessing, and specified cardiac assessments when performed as part of the same CCTA scan. Coronary calcium scoring done as part of the same cardiac CT encounter isn’t separately reported with the standalone calcium-scoring code. Providers should also check current NCCI edits before billing ECG monitoring, 3D rendering, or another cardiac CT code separately on the same date.

Does CPT 75574 Include Calcium Scoring?

Yes, when it’s performed as part of the same cardiac CT encounter. CPT 75571 is meant for standalone, noncontrast calcium scoring performed as its own study, not as an automatic second line item next to 75574. Coding guidance for the cardiac CT code family treats calcium assessment as part of the contrast codes 75572 through 75574 when performed in that same session, and billing 75571 alongside them on the same date typically triggers an NCCI edit. What actually happened during the encounter, and what the report supports, controls whether that applies to a given claim.

Is 3D Postprocessing Separately Billable?

No, not as a routine matter. Three-dimensional postprocessing is already built into this code. Adding 76376 or 76377 on top of it, just because a 3D workstation was used, isn’t supported by the code descriptor. Check the current NCCI manual and any payer-specific edits before adding either code to a CCTA claim.

Is ECG Monitoring Separately Reportable?

Cardiac CT studies often include ECG-related monitoring or gating as part of image acquisition, and that monitoring is generally built into the cardiac CT code itself. An ECG code shouldn’t get added automatically just because cardiac monitoring happened during the scan. A medically necessary, separately performed diagnostic ECG is a different situation from integral gating, and the distinction has to show up in the documentation. Review NCCI and payer-specific edits rather than applying a blanket rule either way.

Can Multiple Cardiac CT Codes Be Reported Together?

Generally, only the code that represents the completed service gets reported. Stacking 75571, 75572, 75573, and 75574 to describe pieces of a single exam isn’t supported, and modifier 59 doesn’t make a bundled combination payable just by being attached to the claim. A genuinely distinct, separately documented encounter is the rare exception, and it needs its own supporting record and payer validation before it’s billed that way.

Effective medical billing services apply code-pair edits before a claim goes out, instead of waiting for a payer denial to expose an unbundling problem. ONE O SEVEN RCM validates cardiac-imaging code combinations, component billing, and payer edits before every claim is released.

How Should CPT 75574 Be Billed With Global, 26, and TC Components?

Bill CPT 75574 without modifier 26 or TC when a single eligible entity furnishes and bills the complete global service. Add modifier 26 when billing only the physician’s interpretation and report. Add modifier TC when billing only the equipment, technologist, supplies, and other technical resources. One billing entity shouldn’t report the global service and a component line for the same work.

Global Billing

Global billing means no 26 or TC modifier, because one entity is billing the full service. That entity has to have actually furnished, or properly arranged, both the professional and technical sides of the work. Duplicate component claims on top of a global claim are a fast way to draw a payer’s attention.

Modifier 26 for the Professional Component

Modifier 26 covers the physician’s interpretation and written report. The rendering and billing provider information has to line up correctly, and the place of service on the claim should match where the interpretation actually happened. Modifier 26 doesn’t change the underlying medical-necessity rules; it only tells the payer which half of the service this particular claim represents.

Modifier TC for the Technical Component

Modifier TC covers the scanner, the technologist, contrast-related technical resources, and supplies, billed by whichever facility or technical provider furnished them. Not every hospital bills TC on a professional claim; hospital outpatient billing runs through the facility claim structure instead, and mixing the two up is a common source of rejected claims.

Place of Service and Facility Context

Place of service matters across a few common settings: a physician office under POS 11, hospital outpatient under POS 22, and independent diagnostic testing facilities where applicable, plus cases where the professional interpretation happens somewhere other than where the scan was performed. A POS error doesn’t always trigger an outright rejection; depending on the claim, it can also produce a straight denial, an incorrect payment, or later audit exposure. A freestanding imaging center billing a cardiac CTA study, sometimes labeled CTCA on the original order, should confirm its POS code matches its facility type before the claim goes out.

When Modifier 59 or an X Modifier May Be Considered

This one stays narrow. Modifier 59, or the more specific X modifiers, should only apply to a genuinely distinct service, and that distinction needs documentation behind it, not just a coder’s judgment call. The modifier can’t be used to override an edit on its own, and it only works when the payer and the code pair actually allow it. A separate encounter, a distinct anatomical circumstance, or a clearly different service has to be evident in the record. Modifier 59 isn’t a routine modifier for coronary CTA billing, and treating it that way is a documented audit risk.

If one entity bills both components, use the global code. If the entity bills interpretation only, use modifier 26. If the entity bills technical resources only, use modifier TC.

The billing entity, component modifier, place of service, ordering information, and payer contract all need confirmation before a claim goes out, which is exactly what ONE O SEVEN RCM’s revenue cycle management services check. Full-service medical billing runs 3.0% of payer collections, with no upfront fee and no setup charge, so the fee stays tied to the revenue the practice actually receives.

Review Your CCTA Billing Workflow

Confirm that code selection, component billing, and payer edits are aligned before the next CCTA claim goes out.

Is CPT 75574 Covered by Medicare in 2026?

Medicare may cover 75574 when the CCTA is medically reasonable and necessary and the claim meets the applicable Medicare Administrative Contractor’s requirements. Coverage depends on the patient’s documented condition, the clinical reason for the test, the diagnosis reported, and the relevant LCD or billing article. A code’s presence on the Medicare fee schedule doesn’t guarantee payment on its own, and a scan performed for the wrong clinical reason can still get denied even with flawless coding.

Medicare Coverage Is Not One Universal Diagnosis List

CMS Article A56737 complements an applicable local coverage determination, and its national coverage policy field is listed as not applicable, which means MAC documents can differ by jurisdiction. Providers need to identify the correct MAC for the patient and the service location, and a diagnosis accepted under one MAC’s article shouldn’t be assumed to travel to every other jurisdiction in the country. CMS states that A56737 complements its related LCD and that the diagnosis reported must best describe the condition the service was performed for. A billing team working across multiple states needs to track which article applies where, not assume one region’s rule covers the rest.

How Should the ICD-10-CM Diagnosis Be Selected?

Selecting the diagnosis follows a set order: review the ordering note, review the patient’s symptoms and known conditions, review available diagnostic results, select the diagnosis that accurately reflects the documented condition, and confirm it’s accepted under the applicable payer or MAC policy. Reviewing which CPT 75574 ICD-10 codes a given MAC accepts is one of the fastest early checks a coder can run. A symptom diagnosis shouldn’t get replaced with angina or coronary artery disease just to chase payment, even when a coder suspects the true condition. CMS instructs providers to report the test result when it’s known, and to report the symptoms that prompted the test when the result isn’t known yet.

Medicare Coverage Verification Workflow

Medicare coverage for CPT 75574 comes down to medical necessity, accurate diagnosis reporting, documentation, and the applicable MAC policy, not the procedure code by itself.

Does CPT 75574 Require Prior Authorization?

CPT 75574 prior authorization requirements depend on the patient’s payer, benefit plan, place of service, ordering provider, rendering provider, and date of service. A payer’s medical policy may explain when a CCTA is medically necessary, but that policy on its own doesn’t confirm whether authorization is required. Practices should verify the exact member plan before scheduling the service.

Medical Necessity Policy and Authorization Are Different

A medical policy identifies the clinical circumstances a payer considers appropriate. An authorization program decides whether advance payer review is required before the claim gets submitted. A service can satisfy a clinical policy and still get denied because nobody obtained authorization first, and an authorization number doesn’t guarantee payment if the final claim ends up differing from the approved service. Aetna’s current cardiac CT policy lists clinical circumstances under which cardiac CT and coronary CTA may be considered medically necessary, and it was last reviewed on April 13, 2026. Treat it as a payer-specific example, not a universal authorization rule.

Seven-Step CCTA Authorization Workflow

A dependable CCTA prior authorization process runs through the same seven checks every time:

1. Verify active eligibility.
2. Confirm whether the code requires authorization.
3. Confirm the approved place of service.
4. Confirm the ordering provider.
5. Confirm the rendering provider or facility.
6. Submit clinical records supporting the requested study.
7. Match the authorization to the scheduled and billed service before the test.

Authorization Details That Must Match the Claim

Nine fields have to line up between the authorization and the claim: member ID, date range, CPT code, facility, ordering provider, rendering provider, number of approved units, authorization number, and clinical indication. A mismatch on any one of these is enough to trigger a denial even when the underlying cardiac CTA was medically appropriate.

ONE O SEVEN RCM verifies eligibility, authorization requirements, approved service details, and payer status before the scheduled scan, so a missing field doesn’t surface for the first time after the claim is already out the door. Its prior authorization services team handles this before the appointment, not after.

What Documentation Is Required for CPT 75574 Claims and CMS Audits?

The CPT 75574 documentation requirements should establish why the study was ordered, what service was performed, who interpreted it, and how the findings support the claim. The record needs relevant history, exam findings, prior diagnostic information, a formal written report, retained images, and reconstruction data, plus ordering-provider information and an accurate ICD-10-CM diagnosis where required. CMS Article A56737 requires documentation supporting medical necessity, relevant history, exam findings, pertinent diagnostic results, a formal report, images, and maintained computerized reconstruction data.

Ordering and Medical-Necessity Documentation

The chart should retain the ordering provider’s name and NPI where required, the clinical indication, relevant symptoms, known cardiac conditions, previous testing, the reason a CCTA was selected over another study, relevant surgical or graft history, and payer authorization information where applicable. Not every patient needs a prior stress test on file; the record should reflect the clinical pathway that actually happened, not a template pathway that didn’t. A coder reviewing the chart later should be able to answer, in one read, why this particular patient needed this particular scan.

Formal Report Requirements

A complete report includes patient-identifying information, the date of service, the interpreting provider, the reason for the test, the contrast-enhanced coronary evaluation, findings, an interpretive conclusion, bypass-graft findings when relevant, images, reconstruction data, and a signed or authenticated report. CMS requires the formal report to include identifying demographics, the interpreting provider, the reason for the test, and an interpretive report, with images and reconstruction data maintained on file.

CMS RAC Readiness

A CPT 75574 audit under the approved CMS review topic targets outpatient hospitals, applies across every A/B MAC jurisdiction, and examines coverage, coding, medical necessity, and documentation. CMS approved this topic on August 28, 2025.

A focused medical billing audit compares the order, clinical note, authorization, report, code, modifier, place of service, and claim before an external review finds the gap first. ONE O SEVEN RCM runs that comparison before CMS does.

How Much Does CPT 75574 Reimburse in 2026?

There’s no single nationwide CPT 75574 reimbursement amount. Medicare payment varies by professional, technical, or global billing; provider locality; place of service; geographic practice-cost adjustments; and 2026 qualifying-APM status. Hospital outpatient facility payment follows OPPS and APC rules rather than the Medicare Physician Fee Schedule, and commercial reimbursement depends entirely on the provider’s contract. CMS’s CMS Physician Fee Schedule tool provides pricing, RVUs, and payment-policy information with national or locality-specific searches.

Medicare Physician Fee Schedule Payment

The 2026 CPT 75574 fee schedule runs on two separate Medicare conversion factors: $33.5675 for clinicians in a qualifying Alternative Payment Model, and $33.4009 for everyone else, both up from 2025. Pull the exact dollar amounts from the CMS Physician Fee Schedule Lookup and the July 2026 CMS payment file immediately before publishing this page. Third-party reimbursement sites shouldn’t be the final source for a number this specific.

Hospital Outpatient APC 5572

Codes 75572 through 75574 moved from APC 5571 to APC 5572 in the 2025 OPPS final rule. The national technical payment increased from approximately $175 in 2024 to approximately $357 in 2025, close to a 104% jump, and the ACR CCTA reimbursement update confirms the codes remain in APC 5572 for 2026 on a provisional basis. CMS reassigned the codes after a simulated cost analysis showed the cardiology revenue code had been artificially holding down the cost inputs used to set the APC. Don’t describe the 2025 figure as a locked-in 2026 allowed amount; CMS has said it may revert the classification if hospital billing patterns don’t shift enough over the next several years.

Chargemaster and Revenue-Code Accuracy

Hospitals need their chargemaster to reflect actual CCTA resource use, and revenue-code selection should match the hospital’s cost center and the real resources behind the scan: nursing, technologist time, medication, equipment, and reconstruction work. Not every hospital should default to one revenue code across the board. ACR notes that accurate revenue-code and cost-report mapping helps reflect the operating resources a CCTA study actually requires.

How Do CPT 75577 and CPT 75580 Relate to Coronary CTA?

CPT 75574 reports the coronary CTA acquisition and interpretation of coronary anatomy. CPT 75577 reports software-assisted coronary plaque assessment and became a Category I code for 2026. CPT 75580 reports a noninvasive fractional flow reserve estimate derived from a CCTA dataset. Plaque assessment and FFR-CT answer different clinical questions, and they carry separate documentation, coverage, and payment requirements from each other and from the base CCTA.

CPT 75577 for Coronary Plaque Assessment

CPT 75577 became effective for 2026 reporting as a Category I code, replacing the deleted Category III codes 0623T through 0626T. It covers augmentative software analysis of coronary plaque and requires its own interpretation and report; it isn’t another name for FFR-CT, and it isn’t billed as a substitute for the base coronary CTA. The ACC 2026 coding update confirms this code replaced the deleted plaque-analysis Category III codes beginning January 1, 2026.

CPT 75580 for FFR-CT

CPT 75580 is based on data pulled from a CCTA and estimates whether a coronary lesion may be flow-limiting. It includes professional interpretation and reporting, and it shouldn’t get described as plaque quantification, since that’s a separate analysis under the plaque-assessment code covered above. Coverage for the underlying coronary CTA doesn’t automatically establish coverage for FFR-CT; payer criteria and documentation need their own review. SCCT’s code list, cited earlier in this guide, places 75580 in a separate fractional flow reserve category derived from CCTA data, apart from the primary cardiac CT codes.

Billing Controls for Advanced Analysis

Before billing either advanced analysis, confirm there’s a separate clinical need, an applicable order, a completed analysis, an interpretation and report, the required software, payer coverage, prior authorization where applicable, the correct date of service, the correct professional and technical billing model, and whether the work was performed internally or by an outside vendor. FFR-CT billing in particular deserves its own review, since a payer that covers the base CCTA doesn’t automatically cover the added analysis.

CPT 75577 reports coronary plaque assessment, and CPT 75580 reports noninvasive fractional flow reserve derived from CCTA data. The two describe different analyses of the same underlying scan and shouldn’t be used interchangeably or as substitutes for one another.

Why Are CPT 75574 Claims Denied and How Should Each Denial Be Corrected?

The most common CPT 75574 denial reasons trace back to missing authorization, a mismatch between diagnosis and documentation, the wrong cardiac CT code, bundled-service reporting, component-modifier errors, place-of-service inconsistencies, or incomplete claim data. The right response depends on the cause. Some claims need a corrected resubmission, and others need medical records, reconsideration, or a formal appeal.

Authorization and Eligibility Denials

Check whether authorization was actually required, then verify the approved code, facility, provider, dates, and units against what was billed. Figure out whether the real problem is missing authorization or a mismatch between what was approved and what got submitted, and don’t file a coding appeal when the underlying issue is an authorization gap.

Medical-Necessity and Diagnosis Denials

Compare the order, the clinical note, the final report, the diagnosis, and the payer’s policy side by side. Confirm the diagnosis accurately reflects what’s in the record, and submit documentation that supports the actual clinical indication rather than the indication a payer might prefer to see. Never swap in an unsupported diagnosis to chase coverage.

Coding and Bundling Denials

The most frequent CCTA claim denial in this category involves the wrong cardiac CT code, a separate calcium-score line that should have been bundled, a separate 3D-rendering charge, modifier 59 used without documentation behind it, duplicate cardiac CT codes on the same claim, and a professional-technical component conflict between two billing entities. A cardiac CTA report that clearly states the completed service heads off most of these before a coder ever touches the claim.

Place-of-Service and Billing-Entity Denials

Verify where the service was actually performed, who furnished the professional component, and who furnished the technical component, then compare all of that against the payer contract and each provider’s enrollment status.

A corrected claim fits when the submitted claim itself contains incorrect data. A records response fits when the payer needs documentation to adjudicate what’s already on file. Reconsideration fits when the payer misapplied its own rule or missed something submitted. A formal appeal fits when the claim stays denied despite documented compliance. Rebilling blindly isn’t a strategy; repeated identical submissions tend to create duplicate denials instead of resolving the original one.

Denial management services should identify the root cause, choose the correct correction or appeal path, and fix the upstream workflow so the same denial doesn’t keep recurring. ONE O SEVEN RCM’s denial management services review authorization, coding, documentation, payer policy, and remittance data before deciding the next move on a denied CCTA claim.

How ONE O SEVEN RCM Manages the Complete CCTA Revenue Cycle

Coronary CTA revenue depends on a connected workflow, not a single well-coded claim: eligibility, authorization, documentation, coding, modifier and POS review, claim submission, payment posting, denial management, underpayment review, and AR follow-up all have to work together.

Before the Service

ONE O SEVEN RCM handles eligibility verification, benefit review, authorization requirements, ordering and rendering provider validation, network and enrollment status, and documentation readiness before the patient is ever scanned.

Before Claim Submission

That includes cardiac CT code selection, ICD-10-CM validation, review of the 26 and TC components, POS review, bundling edits, payer-specific claim scrubbing, and a final documentation check, all before the claim leaves the building.

After Claim Submission

Work continues with claim-status monitoring, payment posting, contracted-rate comparison, underpayment identification, denial correction, appeals, AR follow-up, and trend reporting, so a pattern of denials gets caught before it repeats for another six months.

Full-Service Medical Billing

3.0% of payer collections, with no upfront fee and no setup charge. ONE O SEVEN RCM’s full-service medical billing fee is tied to collected payer revenue, not claim volume, so the incentive is to get claims paid, not just submitted. That structure, combined with specialty-specific cardiology coding, is part of why cardiology practices count ONE O SEVEN RCM among the more affordable, expert medical billing partners available, especially against a national average of 5% to 8% of collections for comparable full-service billing.

Provider Credentialing

$107 per insurance. Provider credentialing services matter when a new provider, facility, location, or payer enrollment needs to go live before claims for that scan can be reimbursed at all. Not every CCTA claim requires new credentialing, but a practice can’t bill a payer it isn’t enrolled with.

CPT 75574 FAQs and Final Claim-Readiness Checklist

What is the CCTA CPT code?

The primary coronary CTA code is 75574. It evaluates the coronary arteries and bypass grafts when present, uses contrast, and includes 3D postprocessing. Code selection still depends on the completed and documented service, not just the equipment used to perform it.

Does 75574 include calcium scoring?

Calcium scoring performed as part of the same cardiac CT encounter is included in 75574. CPT 75571 shouldn’t get added routinely on top of it. Standalone, noncontrast calcium scoring performed as its own study is reported differently, under 75571 alone.

How is CPT 75572 different from coronary CTA?

CPT 75572 focuses on non-coronary cardiac structure and morphology. A coronary CTA evaluates the coronary arteries and bypass grafts instead. The documented anatomical target, not the department that ran the scan, controls which code applies.

What is the difference between 71275 and coronary CTA?

CPT 71275 describes CTA of the chest. Coronary CTA focuses specifically on the coronary arteries and bypass grafts. They aren’t interchangeable just because both involve contrast and CT angiography.

Is 75574 covered by Medicare?

It may be covered when it’s medically necessary. The applicable MAC policy and supporting documentation both need to check out, since coverage isn’t guaranteed by the code alone.

How much does a coronary CT angiography cost?

Patient cost and provider reimbursement are two different questions. Cost varies by setting, payer, deductible, coinsurance, locality, and whether the claim is billed globally or by component. For Medicare payment specifically, check the CMS Physician Fee Schedule lookup rather than relying on a single published number.

What is the final claim-readiness check?

1. Correct cardiac CT code selected
2. Accurate diagnosis on the claim
3. Medical necessity documented
4. Authorization verified
5. Correct provider and facility listed
6. Correct global, 26, or TC billing
7. Correct place of service
8. Bundling edits passed
9. Signed final report on file
10. Claim and supporting records retained

Payment on a CPT 75574 claim comes down to the whole workflow, not any single step in isolation. A clean report doesn’t help a claim with the wrong place of service, and a perfect authorization doesn’t rescue a claim with the wrong modifier. ONE O SEVEN RCM reviews coding, documentation, authorization, and payer policy together, before the claim goes out, so a coronary CTA doesn’t turn into weeks of appeals.
