CPT 75580 Billing Guide: 2026 FFR-CT Coverage, Documentation, Reimbursement, and Denial Prevention

CPT 75580 reports a noninvasive estimate of coronary fractional flow reserve, produced when augmentative software analyzes a coronary CT angiography dataset that was already acquired. A physician or other qualified healthcare professional reviews that estimate and writes the interpretation and report. The code doesn’t cover the original CT acquisition. Coverage and payment depend on the payer, the policy, and the record behind the claim.

The full name of the service is fractional flow reserve derived from computed tomography, or FFR-CT. The 75580 CPT code description centers on two pieces of work: the software analysis of an existing CCTA dataset, and the professional interpretation and written report that follows it.

CPT code 75580 carries billing risk because the work often crosses organizations. One facility acquires the CCTA, a software platform runs the analysis, and a physician somewhere else signs the report. The authorization, the ordering provider details, the source study, the code, and the payment all have to describe the same completed service, which is the connection cardiology RCM services are built to hold together from authorization through payment reconciliation.

What Does CPT 75580 Report?

FFR-CT uses software to estimate the effect of coronary artery narrowing on blood flow from an existing CCTA dataset. The CCTA itself shows anatomy: where a vessel narrows and by how much. FFR-CT goes further and models whether that narrowing restricts flow enough to matter clinically. Invasive FFR answers the same question inside the cath lab, where a pressure wire compares pressures on either side of the lesion to produce a physiologic ratio. The FFR CPT code applies to the noninvasive version, built from image data the patient already has, with no second scan and no catheter.

What FFR-CT Measures

A coronary CTA is an anatomical study. It tells the cardiologist that the mid left anterior descending artery is narrowed, and roughly how tight that narrowing is. It doesn’t directly measure whether that lesion is restricting flow to the muscle downstream.

That functional question is what the analysis answers. The software returns vessel-specific values that estimate the pressure drop across the lesion, which helps the cardiologist decide whether the patient needs the cath lab or medical therapy. Payer thresholds for stenosis severity sit in a later section, because those belong to coverage policy rather than to the code definition.

How Is CT-FFR Performed on the CCTA Dataset?

The workflow runs in six steps, and no step involves putting the patient back in the scanner.

1. Acquire the coronary CTA and complete the standard CCTA study.
2. Review the CCTA and confirm the image quality supports further analysis.
3. Transmit the appropriate dataset for FFR-CT analysis.
4. Let the software model coronary blood flow and pressure across the vessels.
5. Review the resulting estimates against the clinical picture.
6. Have a qualified professional provide the interpretation and sign the written report.

What the Reported Service Includes

The CPT code for FFR analysis of CCTA data covers the software analysis, the review of the resulting estimate, the professional interpretation, and the written report. It doesn’t cover the CT acquisition. There are no separate professional and technical CPT numbers for it either, which is a different point from whether component billing is available. That question is settled by the payer and the billing arrangement, and it comes up later in this guide.

When Did CPT 75580 Replace the Category III FFR-CT Codes?

The 75580 CPT code became effective January 1, 2024, replacing Category III codes 0501T, 0502T, 0503T, and 0504T for the FFR-CT service. The direction of that change trips people up. The permanent code replaced the temporary ones, not the other way around.

Before January 1, 2024: 0501T through 0504T.

Beginning January 1, 2024: 75580.

In 2026: verify the current payer policy and payment system for each date of service.

What Changed on January 1, 2024

Four Category III codes came out of the book and one Category I code went in. Reporting consolidated into a single code, and claims should carry the code that applies to the date of service. Practices billing a 2026 date of service with a T-code are billing a code that no longer exists.

That transition didn’t hand anyone universal coverage. The AMA recognized 75580 as the first Category I code built on the augmentative descriptor, tied to AI-assisted analysis of data derived from coronary CTA with interpretation and reporting by a physician or other qualified healthcare professional, per AMA CPT 75580 guidance.

What Category I Status Does Not Mean

A permanent code number settles how the service is reported. It doesn’t settle any of the following:

• That every payer covers the service.
• That prior authorization is unnecessary.
• That a given patient meets medical necessity.
• That every billing entity can report the full service.
• That a fee schedule amount guarantees payment.

2026 coding status: 75580 remains the core Category I code for noninvasive coronary FFR analysis from CCTA data. Practices should still verify current CPT instructions, payer policy, NCCI edits, and payment-setting rules for each date of service.

CPT 75574 vs CPT 75580 vs CPT 75577

CPT 75574, CPT 75580, and CPT 75577 describe different services that may use the same underlying coronary CT environment, but they do not represent the same analysis.

75574 describes the coronary CTA, 75580 describes FFR-CT analysis from CCTA data, and 75577 describes quantitative coronary plaque analysis.

Practices handling the wider set of diagnostic and interventional heart procedures can work from ONE O SEVEN RCM’s guide to cardiology CPT codes for the surrounding code families.

CPT 75574 Reports the Underlying CCTA

The 75574 CPT code covers acquisition and interpretation of the coronary CT angiography itself, including contrast material when used and the image post-processing on a separate workstation. Billing teams searching for the CCTA CPT code land here. CPT code 75574 produces the dataset that the other two analyses depend on.

75580 Reports the FFR-CT Analysis

This code sits downstream of the CCTA. It uses data the scanner already captured, applies a different analysis to it, and produces a separate interpretation and report. Sharing a dataset with 75574 doesn’t make it part of 75574.

75577 Reports Coronary Plaque Analysis

Plaque quantification and flow estimation answer different clinical questions, and the 75577 CPT code exists for the plaque side. It doesn’t replace the FFR analysis and shouldn’t be substituted for it. CMS added 75577 to the applicable AI-enabled coronary plaque analysis articles effective January 1, 2026, replacing the previous Category III codes in those policies, as shown in the CMS coronary plaque analysis article.

Can These Services Be Reported From One CCTA Acquisition?

They may use data from the same acquisition. That fact alone establishes neither coverage nor separate payment. Before reporting more than one of them, verify the coding instructions, medical necessity, authorization, payer edits, billing entity, date of service, and setting. Medicare CCTA coding guidance is contractor-specific, and the CGS CCTA billing article is one MAC example rather than a national rule.

Is CPT 75580 Covered by Medicare in 2026?

Medicare may cover CPT 75580 when the service meets the requirements of the applicable Medicare Administrative Contractor policy, the related billing article, medical necessity criteria, documentation rules, and claim requirements. A valid code number doesn’t guarantee coverage, and it doesn’t guarantee payment. Coverage answers sit in the policy that governs the patient’s plan and the provider’s jurisdiction.

National Coverage, Local Coverage, and Billing Guidance Are Different

Four terms get used interchangeably in billing conversations, and they don’t mean the same thing.

Noridian Example: Article A58095 and LCD L38613

A58095 is a Noridian Billing and Coding Article covering Jurisdictions JE and JF, and its current revision became effective March 5, 2026 as part of a non-substantive consolidation of the two jurisdictions. It complements LCD L38613. Providers outside those states work under their own MAC’s policy, and the discussion below is one jurisdictional example rather than a national rule. The article describes FFR-CT as post-procedure analysis of a previously performed CCTA, requires ordering or referring provider information on the claim, and warns that NCCI and OPPS edits may apply. The full text sits in CMS Article A58095.

Two details in that article drive claim outcomes more than anything else in it: the ordering provider requirement, and the post-procedure framing that ties the analysis back to a prior CCTA.

Is There a National 75580 NCD?

A58095 and L38613 both reference NCD 220.1 for the broader computed tomography framework. That national policy sets the general CT coverage structure, and it isn’t a standalone guarantee that every FFR-CT service is payable. The detailed criteria live in the applicable LCDs and billing articles instead. Providers can read the national framework in CMS NCD 220.1.

So a search for a 75580 NCD returns the CT framework rather than a code-specific national rule. Teams looking for CMS guidelines for 75580 should work from the MAC policy that covers their jurisdiction.

Original Medicare vs Medicare Advantage

Original Medicare coverage depends on the applicable MAC and jurisdiction, which is why one practice can collect on a claim that another practice loses on identical documentation. Medicare Advantage plans must follow applicable Medicare statutes, regulations, NCDs, and LCDs. Where Traditional Medicare criteria are not fully established, a plan may apply publicly available, evidence-based internal criteria consistent with CMS requirements. Verify the member’s exact plan and policy version before the analysis happens, not after the denial arrives.

Who May Meet FFR-CT Medical Necessity Criteria?

Medical necessity criteria for FFR-CT vary by payer, plan, Medicare jurisdiction, policy version, patient presentation, CCTA findings, and image quality. No single clinical profile qualifies a patient everywhere. The policy that governs the claim is the one that decides.

Criteria Under Noridian LCD L38613 (Jurisdictions JE and JF)

L38613 is a Noridian policy covering Jurisdictions JE and JF: California, Hawaii, Nevada, Guam, American Samoa, the Northern Mariana Islands, Alaska, Arizona, Idaho, Montana, North Dakota, Oregon, South Dakota, Utah, Washington, and Wyoming. Providers outside those states work under a different MAC policy. The full text sits in CMS LCD L38613.

The policy covers FDA-approved FFR-CT technology in three scenarios. Read them separately, because they don’t share the same patient-risk requirement.

Scenarios A and B state an intermediate-risk requirement. Scenario C does not, and it does not carry the proximal or middle vessel limitation either. Collapsing all three into a single intermediate-risk rule misstates the policy. L38613 defines intermediate risk, high risk, and stress testing by reference to the 2021 AHA/ACC chest pain guideline, and persistent symptoms as ischemia-related symptoms that continue despite maximally tolerated medical therapy.

One further condition applies across all three scenarios. Under L38613, FFR-CT is covered as an alternative to stress testing, not alongside it, unless the CCTA was not of sufficient quality for the analysis and another study is needed.

L38613 Exclusions and Limitations

The policy lists eleven circumstances where it does not consider FFR-CT reasonable and necessary. These matter more to a billing team than the qualifying criteria do, because a patient can satisfy scenario A and still fall inside an exclusion.

1. Prior placement of prosthetic valves
2. Prior placement of coronary bypass grafts
3. Suspicion of acute coronary syndrome where MI or unstable angina have not been ruled out
4. Intracoronary metallic stent
5. Status post heart transplantation
6. Recent MI, 30 days or less
7. Prior pacemaker or defibrillator lead placement
8. Newly diagnosed systolic heart failure with no prior left heart catheterization
9. Left main coronary artery disease with intermediate coronary stenosis at 40% lumen reduction or less
10. Non-obstructing stenosis under 50% of all major epicardial vessels on CTA or catheterization in the past twelve months, absent a new symptom complex
11. Situations where turnaround time may affect prompt clinical care decisions

L38613 also sets boundaries at both ends of the stenosis range. Above 90%, the policy treats the analysis as not medically necessary because the patient should proceed to catheterization. Below 40%, it treats confirmatory data as unnecessary. The policy also states the service should not be performed until the base CCTA has been completed and interpreted.

Every threshold and exclusion above belongs to L38613. None of it is a universal rule, and applying it to a commercial claim or to another MAC jurisdiction is how a billing team argues itself into a denial it could have predicted. L38613’s current version applies from March 5, 2026, a revision that consolidated the JE and JF contractor information into one document and did not change the coverage criteria.

Factors That May Affect Eligibility

Coverage policies weigh some combination of the following. Which ones apply, and how heavily, depends on the policy in force.

• Acute or stable chest pain presentation
• Patient risk category
• Known or unknown coronary artery disease
• CCTA findings, including the location and severity of stenosis
• Image quality of the source study
• Previous tests or procedures
• Policy-specific exclusions and FDA-approved technology requirements

Why Policy Verification Must Happen Before Billing

Ischemic heart disease presentations look similar across payers. The coverage rules for 75580 don’t. Before the analysis is performed, the billing team should confirm eight things:

1. The member plan and product line
2. The policy number that governs the service
3. The effective date of that policy version
4. The medical necessity criteria the policy states
5. Whether prior authorization is required
6. Which rendering entity the policy approves
7. What supporting documentation the policy expects
8. The reference or authorization number, retained in the file

Verifying a code isn’t enough when each payer can apply different authorization and medical necessity requirements to the same clinical picture. ONE O SEVEN RCM’s prior authorization services confirm the active policy, the required clinical records, the approved service, and the authorization status before the claim goes anywhere near submission.

CPT 75580 Documentation Requirements

Documentation should connect the original coronary CTA, the clinical reason for the analysis, the ordering or referring provider, the software analysis, and the final professional interpretation and report. Two of those are stated requirements. The rest is audit-ready practice.

Ordering and Referring Provider Information

A58095 states that the referring or ordering physician’s name and NPI must be reported, because the service is post-procedure analysis of a previously performed CCTA. It is a claim-level requirement rather than a clinical one, and it can stop a claim that meets every coverage criterion.

Capture the ordering or referring provider’s name, the NPI where required, a valid order or request, and the connection between that provider and the CCTA data being analyzed.

Source CCTA Documentation

The source CCTA report has to be retrievable on request. Keep the date of the original study, the final CCTA report, the relevant anatomical findings, and evidence that someone reviewed the CCTA before the analysis was ordered. Note the source facility or provider when it differs from the billing entity, and confirm the source image quality supported the analysis.

Clinical Documentation

The record should show the symptoms and clinical findings, the reason for the original CCTA, the reason the additional analysis was medically necessary, and the relevant risk and patient-history information. Policy-specific elements go in alongside those. A diagnosis code alone does not establish medical necessity when the medical record doesn’t satisfy the applicable coverage policy.

FFR-CT Interpretation and Report

The signed interpretation and report are essential documentation, though the code represents both the augmentative software analysis and the professional interpretation and report, not the report alone. The report should identify the analysis performed, the relevant coronary findings, the FFR result or values where clinically appropriate, the professional interpretation, the interpreting provider, a signature and date, and a clinical conclusion. Report templates should be reviewed by a qualified coding and clinical compliance professional before a practice standardizes on one.

Explicit requirements: A58095 requires the referring or ordering physician’s name and NPI on the claim. L38613 requires the record to support its coverage criteria. Payer-specific requirements sit in each policy. Everything else on the checklist below is recommended audit-ready documentation rather than a stated national requirement.

1. Ordering or referring provider documented
2. Ordering NPI captured when required
3. Original CCTA report available
4. Relevant symptoms and findings documented
5. Applicable payer criteria supported
6. Authorization retained when required
7. FFR-CT analysis report completed
8. Professional interpretation signed
9. Billing entity and date of service validated
10. Records retained for audit or appeal

Pre-Submission Billing Workflow for FFR-CT Claims

Before an FFR-CT claim is released, the billing team should verify that the clinical service, the code, the billing entity, the supporting records, the payer requirements, and the claim data all describe the same completed service. A failure in any one of those six can stop the claim on its own.

Validate the Service Performed

Confirm the original CCTA exists and the analysis was completed. Confirm the interpretation and report are available and signed. Confirm the entity submitting the claim performed the work being reported, and that the date of service matches the payer’s reporting requirements.

Validate the Code and Claim Data

Check the correct code for the date of service, the billing entity, the rendering provider, the ordering or referring provider and NPI, the place of service, the units, the diagnosis linkage, the authorization number, the claim type, and any payer-specific edits. The 75580 CPT line in the charge master needs the same review as the claim itself, because a stale charge master reproduces the same error every time.

Run Pre-Submission Edits

Run the claim against the current NCCI files, OPPS packaging where it applies, payer-specific code edits, duplicate-claim risk, the component-billing arrangement, the authorization-code match, and the claim-format requirements. Modifier selection is a separate decision covered in the next section.

The seven-step release sequence for CPT code 75580 claims runs as follows.

1. Check the applicable payer policy for the date of service.
2. Confirm authorization covers the analysis, the entity, and the date range.
3. Retrieve the source CCTA report.
4. Retrieve the signed FFR-CT report.
5. Validate the code, component, and claim fields.
6. Scrub the claim against current edits.
7. Release the clean claim.

When these checks sit with different teams, a clinically sound FFR-CT service can still fail at authorization, coding, submission, or payer follow-up. ONE O SEVEN RCM’s medical billing services connect those steps through one accountable workflow, so the handoffs stop being the weak point.

How Do Modifier 26, Modifier TC, and Global Billing Apply to CPT 75580?

Modifier 26 may be appropriate when the billing physician or qualified healthcare professional performs only the professional interpretation and report. Modifier TC may identify the technical component when a separate entity performs only the technical portion. Global reporting may apply when one entity performs the complete reportable service. The modifier has to match the work performed, the billing entity, the place of service, the payer policy, and the contractual arrangement.

When Modifier 26 May Apply

The CPT 75580 modifier 26 question comes down to who did the interpretation. It fits when a physician or qualified professional performs the interpretation and report while another organization performs the technical work. The professional can’t report work that wasn’t personally performed or contractually assigned, and the signed report has to name the billing provider. ONE O SEVEN RCM’s modifier 26 guide covers the PC/TC indicator lookup that decides whether the modifier is even valid on a given code.

When Modifier TC May Apply

The TC modifier belongs to the entity performing the technical component only. That entity shouldn’t also claim the professional interpretation. The payer has to recognize the component arrangement, and the claim should carry the correct place of service and billing entity.

When Global Billing May Apply

Global reporting fits when one entity is responsible for the complete reportable service and meets the payer, enrollment, supervision, and billing requirements that go with it. Ordering the study doesn’t create that responsibility, and billing globally on the strength of having placed the order is a recoupment risk.

How CPT 75574 Affects the Billing Arrangement

75574 reports the underlying coronary CTA and 75580 reports the later analysis. The same organization may report both, or it may report neither. A shared dataset doesn’t prove that one billing entity owns every component, and same-day performance doesn’t guarantee separate payment.

This code isn’t automatically global, and it isn’t a formal add-on code. CMS maintains a separate Add-On Code file for services classified that way, and depending on a prior CCTA dataset doesn’t put a code on it. For code-level pricing, RVUs, modifier applicability, and supervision rules, work from the CMS PFS Lookup Tool, and confirm definitive payment information with the MAC.

How Much Does CPT 75580 Reimburse in 2026?

Reimbursement depends on the payment system, the place of service, the modifier, the geographic locality, provider participation, the payer contract, and whether the clinician is a qualifying APM participant. Hospital outpatient OPPS payment shouldn’t be compared directly against physician fee schedule global, professional, or technical amounts. They come from different payment systems and answer different questions.

CMS finalized two separate 2026 PFS conversion factors. These factors are one input into the payment calculation. Neither one is the payment amount for this code.

Physician Fee Schedule Reimbursement

Work from the current CMS national payment file rather than a rate someone quoted last year. Confirm QP versus non-QP status, confirm the global, 26, or TC configuration, apply locality and GPCI adjustments, and confirm participating versus nonparticipating status where it matters. Multiplying one total RVU by one conversion factor without checking the full file produces a number that looks authoritative and pays differently. CMS released PFREV26C as the July 2026 national payment file, with separate QP and non-QP versions, in the CMS PFS national payment file.

Hospital Outpatient OPPS Reimbursement

The OPPS CPT code 75580 answer lives in the current quarterly Addendum B. Confirm the status indicator, the APC assignment, and the national unadjusted payment, then confirm whether packaging or claim edits change what the hospital actually collects. CMS updates OPPS Addenda A and B quarterly, including a July 2026 Addendum B updated on July 21, 2026, published through the CMS OPPS quarterly addenda. Hospital payment and physician professional payment are separate figures and shouldn’t be quoted as one number.

Commercial Payer Reimbursement

The contracted allowable controls. A payer can cover the code and still apply a rate well below the Medicare figure, and authorization doesn’t guarantee the expected payment. Payment posting should compare the ERA against the contract on every CPT code 75580 claim, because a paid claim can still be an underpaid claim.

CPT 75580 reimbursement table: pull each figure from the named source and label it before publication. Do not carry forward a 2025 rate.

Every dollar figure published on this page should carry the calendar year, the payment system, the setting, the modifier or component, the QP or non-QP status, the national or locality-adjusted status, the verification date, and the source. An unlabeled rate invites misquotation and payer disputes.

Does CPT 75580 Require Prior Authorization?

Prior authorization requirements vary by payer, product line, member plan, network arrangement, and date of service. An authorization obtained for the underlying CCTA doesn’t prove the later analysis is authorized. Verify whether the authorization covers the analysis code, the rendering entity, the place of service, and the approved date range before the analysis happens.

Verify the Exact Payer Product

A payer brand is not a policy. UnitedHealthcare Medicare Advantage and a self-funded UnitedHealthcare employer plan can reach different conclusions on the same clinical file. Confirm which of these the patient actually carries: Original Medicare, Medicare Advantage, commercial HMO, commercial PPO, Medicaid, Medicaid managed care, or a self-funded employer plan.

Match the Authorization to the Completed Service

FFR-CT authorization can fail on a mismatch rather than an absence. The approval exists, and it describes something different from what was performed.

Use Payer Policy as Evidence, Not Assumption

The UnitedHealthcare Medicare Advantage policy effective March 1, 2026 states that listing the code does not itself guarantee coverage or reimbursement, and it directs users to the applicable LCDs and local articles where those exist. Read it in the UHC FFR policy. One plan’s policy is evidence about that plan. It isn’t a national rule, and a CPT 75580 prior authorization workflow built on a single payer’s document will break on the next payer.

Payer verification belongs before the analysis, not after the denial. ONE O SEVEN RCM checks the member plan, the active policy, the required documentation, the rendering entity, and the authorization details before the claim enters billing, and the prior authorization guide walks through the same workflow for practices handling it in house.

Common CPT 75580 Denials, Rejections, and Claim Failures

A claim for this service can fail even when the service was clinically appropriate and the report was excellent. The root cause can sit before submission, inside payer editing, inside medical necessity review, or after payment when the allowed amount doesn’t match the contract.

Rejection vs Denial

A rejection happens before adjudication. A denial happens after the payer adjudicates the claim. Correct a rejection and resubmit it, because pushing a rejected claim into an appeal pathway wastes the appeal window on a claim the payer never processed.

Medical Necessity Failure

These CPT 75580 denial reasons tie back to the active policy, the CCTA findings, the documented symptoms, the diagnosis-to-policy relationship, and the authorization. Work from the documentation checklist earlier in this guide and identify which item the payer couldn’t find. A CO-50 denial guide covers the medical necessity denial pathway in detail, though not every denial on this code returns CO-50.

Coding and Component Failure

Component errors are a recurring failure point on this code, because the work is often split across entities. Check for the wrong component, the wrong provider, an incorrect date, an incorrect unit, an unsupported code pair, or a duplicate submission. CMS states that NCCI Procedure-to-Procedure edits prevent inappropriate payment for services reported together, and the current CMS NCCI PTP edits page carries July 1, 2026 practitioner and hospital outpatient updates.

When the denial reason is unclear, resubmitting the same claim reproduces the same failure. ONE O SEVEN RCM’s denial management services establish whether the problem is authorization, documentation, coding, payer policy, claim configuration, or payment variance before anyone touches the claim again.

Should the Claim Be Corrected, Appealed, Followed Up, or Audited?

The previous section identifies what went wrong. This one decides what to do about it. Choosing the wrong workflow burns the clock on a claim that had a recoverable path.

Not sure whether you’re looking at a correctable claim, an appeal, an unpaid balance, or an underpayment? A CPT-level payment variance audit separates the categories and quantifies the recoverable amount before your team spends another week on the wrong workflow.

Correct the Claim When the Submitted Data Was Wrong

A missing NPI, a wrong place of service, a wrong modifier, a typographical error, an incorrect claim frequency, or a missing authorization number all belong here. These are generally handled through a corrected or replacement claim where the payer permits it. Follow the payer’s correction, reopening, and appeal instructions for the specific claim, because a closed correction window or a policy-interpretation dispute can push the same issue onto the appeal track.

Appeal When the Payer’s Determination Is Disputed

A CPT 75580 appeal package should contain the payer denial notice, the active policy, the CCTA report, the FFR-CT report, the clinical notes, the authorization evidence, a copy of the claim, and a concise argument tied to the payer’s stated reason. Filing windows vary by payer and by product. Confirm the deadline in the denial notice, the payer manual, the participation agreement, and the applicable regulatory requirements rather than working from a remembered number. Medicare redetermination timelines are set by regulation, not by contract.

Audit When the Claim Paid Incorrectly

Compare payment against the contracted allowable. A zero denial rate proves nothing about whether the practice is being paid correctly. Payment posting has to separate contractual adjustment, patient responsibility, payer reduction, and true underpayment, because a 75580 underpayment posted as a contractual adjustment disappears from the aging report and never gets worked. Recurring variance should feed back into the payer and contract rules, and unanswered claims belong with AR follow-up services rather than sitting in a queue until timely filing closes.

How Hospitals, Imaging Centers, and Physician Offices Should Implement 75580

Hospital Outpatient Department

Build the chargemaster line, validate the revenue code against verified payer and facility guidance rather than a number borrowed from another hospital, and confirm the APC and status indicator. Route the institutional claim and the professional interpretation through separate workflows, keep the I/OCE current, and review OPPS payment variance quarterly. CMS updates OPPS Addenda A and B quarterly and issues January, April, and July I/OCE releases for 2026, so an annual chargemaster review leaves three quarters of drift in place. ONE O SEVEN RCM’s hospital RCM services cover outpatient billing, facility claims, payment integrity, and denial coordination on that quarterly cycle.

Imaging Center

Confirm enrollment, then settle technical and professional ownership in writing before the first claim. Where an outside analysis vendor is involved, the contract should document each party’s responsibilities, but billing still has to comply with payer enrollment, reassignment, component ownership, place-of-service, and anti-markup rules. A contract cannot authorize a claim those rules prohibit. Not every imaging center is an IDTF, and independently enrolled suppliers commonly bill professional claims while provider-based or facility arrangements may require institutional billing.

Physician Office

Decide whether the practice bills globally or professional-only, and document that decision. Apply PFS and locality correctly, hold the report documentation to the same standard as the coding, and confirm the payer contract and network status support the arrangement.

When the organization also performs coronary plaque analysis, build separate workflows for CPT 75577 and the FFR analysis. Do not combine them into one charge, and do not assume both are covered because they use data from the same CCTA acquisition.

How ONE O SEVEN RCM Supports the FFR-CT Revenue Cycle

Cardiology billing breaks at the handoffs. The authorization sits with one team, the CCTA report with another, the analysis with a vendor, and the claim with whoever has capacity that week. ONE O SEVEN RCM takes the whole chain, so no step is left to whoever has capacity that week.

End-to-End Billing at 3% of Collections

ONE O SEVEN RCM is one of the most affordable and experienced medical billing companies working with cardiology practices, at 3% of collections received from payers. There’s no upfront fee and no setup charge. That rate covers eligibility and benefit verification, prior authorization coordination, coding validation, claim submission, payment posting, denial management, AR follow-up, and reporting.

Credentialing at $107 Per Payer

Provider credentialing is available at $107 per payer, covering CAQH profile work, the enrollment application, and follow-up through to panel acceptance. Cardiology groups adding an interventional or imaging provider mid-year run into this early, because a provider who is not properly enrolled and credentialed may be unable to receive in-network payment under the intended billing arrangement, regardless of claim accuracy.

ONE O SEVEN RCM’s service fees are separate from Medicare or commercial payer reimbursement. A payer’s allowed amount is revenue paid to the provider. The 3% and the $107 are the cost of managing the agreed billing or credentialing service, and neither figure relates to the payment amounts shown earlier in this guide.

For a CPT-level review of your cardiology billing workflow, and a look at where authorization, documentation, submission, denials, or payment posting may be reducing collections, start with full-service RCM. Practices enrolling new cardiologists can begin with provider credentialing services instead.

Frequently Asked Questions About CPT 75580

What Is CPT Code 75580 For?

CPT 75580 reports a noninvasive coronary FFR estimate produced by software analysis of an existing CCTA dataset, together with the professional interpretation and written report. It doesn’t report the CT acquisition, and coverage depends on the applicable payer policy.

Is 75580 an Add-On Code?

It depends on an existing CCTA dataset, which isn’t the same thing as formal add-on classification. CMS maintains a separate Add-On Code file for services designated that way. Confirm the current licensed CPT instructions and the applicable payer rules before labeling it.

Can 75574 and 75580 Be Billed Together?

They describe different services and may arise from the same clinical workflow. Separate coverage and separate payment depend on the service performed, the payer, the date of service, the setting, the applicable edits, the authorization, and the billing entity.

Is 75580 Covered by Medicare?

Medicare coverage is policy and jurisdiction dependent. Check the LCD and billing article that apply to your MAC. A code appearing in a policy doesn’t guarantee payment, and Medicare Advantage requires verification at the member-plan level.

Can Modifier 26 Be Appended to 75580?

It may apply when the billing provider performs only the professional interpretation and report while another entity handles the technical work. Confirm the actual service performed, the payer policy, the place of service, and the component arrangement before appending it.

How Often Can 75580 Be Reported?

Validate the current CPT instructions, the MUE value, payer frequency rules, the dataset being analyzed, the date of service, and the duplicate-claim history. Published frequency limits vary, so confirm the active files rather than applying a remembered limit.

What Documentation Supports the FFR CPT Code?

The CCTA report, the clinical indication, the ordering provider and required NPI, the analysis performed, the professional interpretation, and the final signed report. Authorization records and payer-specific criteria go in the file where the policy calls for them.

What Is the Difference Between the 75580 CPT Description and the Payer Version?

The official 75580 CPT description defines the service itself. Payer policies sit on top of that CPT 75580 description and add coverage criteria, medical necessity requirements, authorization rules, documentation expectations, and payment terms that the descriptor never addresses.

Before You Submit a 75580 Claim

1. Confirm the applicable payer policy for the date of service.
2. Verify authorization covers the analysis, entity, and date range.
3. Confirm the source CCTA report is on file.
4. Retain the signed FFR-CT report.
5. Validate the ordering provider and NPI.
6. Confirm the billing entity and component.
7. Check current NCCI and payer edits.
8. Verify the payment setting and system.
9. Scrub the claim before release.
10. Compare the ERA against the expected allowable.
