Cardiology Billing Services

Cardiology is one of the most financially rewarding specialties in medicine, and one of the easiest to quietly lose money in. A single left heart catheterization, billed with one missing vessel modifier or one diagnostic angiography code that should've been bundled instead of billed separately, can turn a claim worth thousands into a fraction of that. Revex Square built our cardiology billing services around that reality, not around a generic billing template stretched to cover cath labs, echo studies, and EP procedures it was never designed for.

You didn't spend years training to read echocardiograms and manage arrhythmias so you could also become fluent in modifier 26 versus TC, or track which 85 percent of your cath lab cases need prior authorization before you can even schedule them. That's the work we do instead, so your practice or health system gets paid accurately for the complexity of what cardiology actually involves.

    ◆

    Work With a Cardiology Billing Specialist

    Our team understands cath lab and EP coding, professional-versus-technical component splits, and the prior authorization workload cardiology carries more than almost any other specialty.

    Our Cardiology Billing Process

    We simplify every step of your revenue cycle so your practice can focus on delivering exceptional patient care.

    01

    Patient Registration & Prior Authorization

    Roughly 85 percent of cardiac catheterizations and most advanced cardiac imaging require prior authorization. We submit those requests well ahead of the scheduled procedure, with supporting documentation attached, so a case never gets cancelled or denied for a paperwork gap.

    02

    Charge Capture

    Our team captures every billable component of the encounter, from the office visit and diagnostic testing to catheterization, device work, and any same-day EP procedures.

    03

    Cardiology-Specific Coding

    Certified coders assign accurate CPT, HCPCS, and ICD-10 codes, correctly separating professional and technical components on imaging and device interrogation, and applying vessel-specific modifiers on PCI claims involving more than one artery.

    04

    Claim Submission

    Clean claims are submitted electronically to insurance companies for faster processing and reimbursement.

    05

    Payment & A/R Follow-Up

    We monitor payments, follow up on unpaid claims, and aggressively manage denials tied to bundling disputes, modifier errors, and expired authorizations.

    Accurate Cardiology Coding

    Every procedure, modifier, and diagnosis is carefully reviewed to reduce coding errors, claim rejections, and lost revenue.

    Faster Reimbursement

    Our streamlined billing workflow helps move claims through the revenue cycle and improves your practice's cash flow.

    Cardiology Billing Services We Provide

    Comprehensive revenue cycle solutions designed specifically for cardiology practices.

    01

    Cardiology Medical Coding & Cardiovascular Billing

    Accurate CPT, HCPCS, and ICD-10 coding across diagnostic cardiology, interventional procedures, and electrophysiology. Our certified coders know that billing diagnostic angiography separately when it should have been bundled into the intervention is one of the fastest ways to turn a properly reimbursed PCI claim into a significant underpayment.

    →
    02

    Cath Lab & PCI Billing

    We apply vessel-specific modifiers (LD, LC, RC) correctly on multi-vessel percutaneous coronary intervention claims, matched to the exact artery treated, a detail that's easy to miss and expensive to get wrong.

    →
    03

    EP Studies & Ablation Billing

    Electrophysiology billing depends on arrhythmia type, ablation sites, and mapping technology used, and we sequence diagnostic study and ablation add-on codes correctly so nothing gets bundled or dropped that should have been billed.

    →
    04

    Professional vs. Technical Component Billing

    Echocardiograms, device interrogations, and other cardiac imaging services often split between a technical component (the equipment and facility) and a professional component (the cardiologist's interpretation), billed with modifier TC or 26 respectively, and we make sure the right one lands on the right claim.

    →
    05

    Prior Authorization Management

    We manage the full prior authorization lifecycle for catheterization, advanced imaging, device implantation, and EP procedures, from documentation through submission, follow-up, and appeal.

    →
    06

    Denial Management

    Our team identifies the root cause of denials, corrects billing issues, and follows up with payers to recover lost revenue, including denials tied to modifier errors, NCCI bundling edits, and same-day E/M-and-procedure disputes.

    →
    07

    Accounts Receivable Management

    We monitor outstanding accounts, prioritize aging balances, and actively follow up to accelerate reimbursement.

    CARDIOLOGY-SPECIFIC EXPERTISE

    Cardiology Billing Services Tailored to Your Practice

    Every cardiology practice is different. A diagnostic-heavy general cardiology clinic has different billing needs than an interventional practice running a cath lab, or an electrophysiology group managing complex ablations and device follow-up.

    Revex Square provides specialized cardiology medical billing services built around a specialty that genuinely runs on multi-component procedures, place-of-service-dependent modifier rules, and bundling edits most general billing teams don't fully understand. The 2026 coding updates added new arterial-specific modifier requirements for coronary interventions and refined codes for leadless pacemaker evaluation, and staying current on changes like these is part of what keeps a cardiology practice's clean claim rate high.

    ✓

    Specialty-Specific Coding

    Accurate coding across diagnostic, interventional, EP, and device services, with modifier accuracy that most general billing teams simply weren't trained for.

    ✓

    Payer Expertise

    Experienced handling of commercial, Medicare, and Medicaid payers, including the prior authorization and medical necessity documentation cardiology claims face more consistently than most specialties.

    ✓

    Complete Revenue Cycle

    From eligibility and prior authorization to coding, claims, denials, and A/R follow-up, covering the full path from scheduling to final reimbursement.

    Frequently Asked Questions About Cardiology Billing Services

    Find answers to common questions about cardiology billing services, medical coding, claims processing, prior authorization, denial management, reimbursement, and revenue cycle management.

    Cardiology billing services cover the complete revenue cycle for cardiology practices, including patient eligibility verification, charge entry, medical coding, claim submission, payment posting, denial management, accounts receivable follow-up, and reimbursement tracking. Revex Square helps cardiology practices streamline billing operations and improve revenue cycle performance.

    Cardiology billing can involve complex diagnostic and interventional procedures, specialized CPT and ICD-10 coding, modifier requirements, bundling rules, medical necessity guidelines, and payer-specific authorization requirements. Specialized cardiology billing services help practices manage these requirements and reduce preventable billing errors.

    Our cardiology billing services can support office visits, ECG/EKG services, echocardiography, stress testing, Holter and cardiac monitoring, nuclear cardiology, cardiac catheterization, interventional procedures, and other cardiovascular services. Our team works to ensure services are accurately coded and submitted according to applicable payer requirements.

    Revex Square reviews cardiology claims for coding accuracy, patient eligibility, documentation, medical necessity, modifier usage, bundling edits, and authorization requirements before submission. When claims are denied, our team reviews the denial reason, corrects applicable issues, submits appeals when appropriate, and follows up until resolution.

    Modifier 26 generally identifies the professional component of certain services, while modifier TC identifies the technical component. Correct modifier selection is important because incorrect modifier usage can contribute to claim denials, payment issues, or inaccurate reimbursement.

    Some cardiac procedures and advanced imaging services may require prior authorization depending on the payer, procedure, and patient's insurance plan. Revex Square can help verify authorization requirements, prepare and submit requests, track approvals, and help prevent avoidable authorization-related denials.

    Our cardiology billing services include accounts receivable follow-up for outstanding insurance claims and patient balances. We monitor aging accounts, investigate unpaid or underpaid claims, communicate with payers, resolve billing issues, and follow up on outstanding balances to help cardiology practices recover legitimate revenue.

    Yes. Revex Square provides cardiology billing services for diagnostic and interventional cardiovascular services. This can include ECGs, echocardiograms, stress testing, cardiac monitoring, catheterization, and other eligible cardiology procedures based on the practice's services and payer requirements.

    Yes. Our cardiology billing team can work with your existing EHR and practice management workflow to support charge capture, claim submission, payment posting, denial management, accounts receivable follow-up, and revenue cycle reporting while minimizing disruption to your practice.

    Outsourcing cardiology billing can reduce administrative workload while giving practices access to specialized billing and coding support. Accurate claims, proactive denial management, timely payer follow-up, and effective accounts receivable management can help improve the overall revenue cycle and reduce revenue leakage.

    The cost of cardiology billing services depends on factors such as claim volume, procedure mix, payer mix, and the level of revenue cycle support required. At Revex Square, cardiology billing services start as low as 2.75% of monthly collections, with pricing based on the needs of each practice.

    Cardiology billing involves protected health information, making secure data handling essential. Revex Square's billing workflows are designed to support applicable HIPAA privacy and security requirements while protecting patient and billing information throughout the revenue cycle.
