Cardiology Medical Billing Services
MZ Medical Billing provides specialized cardiology billing services to help practices manage the complexity of coding, compliance, and reimbursement.
We work with all cardiology subspecialties, including General Cardiology, Interventional Cardiology, Electrophysiology, Nuclear Cardiology, Pediatric Cardiology, Cardio-Thoracic Surgery, and Transplant Cardiology. Each specialty involves highly specific billing needs that require precision.
Procedures such as permanent pacemaker implantation (CPT 33208), coronary stent placement (CPT 92928), and electrophysiology studies must be billed with exact CPT and ICD-10 codes. Correct modifier use and compliance with Medicare’s National Correct Coding Initiative (NCCI) and payer bundling rules are also essential.
Cardiology practices face some of the highest denial rates in healthcare, often 15–20%, caused by coding errors, missing prior authorizations, or incomplete documentation. These denials directly impact revenue and delay reimbursements.
MZ Medical Billing helps cardiology practices lower denial rates to 5% or less by coding with accuracy, managing prior authorizations, and maintaining full compliance with payer requirements. This leads to faster payments, stronger cash flow, and more time for physicians to focus on patient care.

Cardiology Medical Billing Services You Can Trust
At MZ Medical Billing, we focus on the specialized financial needs of cardiology practices. Cardiology billing involves some of the most complex coding in healthcare, covering procedures such as pacemaker and ICD implants, coronary interventions, ablations, and nuclear cardiology imaging. Frequent use of modifiers (-26, -TC, -59, -25) and payer-specific bundling rules add to the complexity. Payer denials often stem from incorrect modifier use, prior authorization errors, or incomplete documentation. Our certified coders and billing specialists handle these challenges daily, lowering denial rates to 5% or less and helping cardiology practices secure full reimbursement.
We combine advanced billing technology with cardiology-specific EHR/EMR integration, HIPAA-compliant processes, and years of specialty experience to support practices of all sizes.
Medical Billing Services
We handle the full medical billing workflow for cardiology: charge entry, claims submission, and payer follow-up. Complex procedures like pacemaker implantation (33208), coronary stent placement (92928), and electrophysiology ablation (93656) are billed within strict coverage rules. We also manage global billing for follow-up care, avoiding duplicate or denied claims.
Medical Coding Services
Our certified coders specialize in cardiology-specific CPT, ICD-10-CM, and HCPCS coding. Nuclear imaging (78452), echocardiography, and catheterizations require accurate code selection and modifier use (-26, -TC, -59). This medical billing coding precision prevents claim rejections and supports proper reimbursement.
Provider Credentialing Services
Credentialing is critical for cardiologists, electrophysiologists, and cardiac surgeons to bill insurance carriers. We manage provider enrollment with Medicare, Medicaid, and commercial insurers, update CAQH profiles, and maintain compliance with hospital privileging requirements. This prevents delays in reimbursement and keeps providers in-network.
Practice Audit Services
Cardiology practices risk revenue loss due to coding errors, missed prior authorizations, and improper application of bundling rules. Our practice audits identify compliance issues, undercoding of procedures, missing modifier usage, and trends in payer denials. These audits improve documentation, reduce audit risk, and uncover lost revenue opportunities.
Revenue Cycle Management (RCM)
We manage the full revenue cycle for cardiology practices, from eligibility checks to final payment posting. This includes prior authorizations for stress tests, imaging, catheterizations, and device implants, as well as inpatient and outpatient claims management. Our RCM approach lowers denial rates, keeps Days in A/R under 30, and maintains steady cash flow.
Insurance Verification Services
Cardiology procedures are often high-cost, making eligibility and benefit verification essential. We verify insurance coverage, deductibles, copays, and authorization requirements for services like nuclear stress tests, echocardiograms, ablations, and angioplasty. This reduces denials and improves patient financial transparency.
Prior Authorization Services
Many cardiology services, including cardiac catheterizations, electrophysiology procedures, and nuclear imaging, require prior authorization. We oversee the submission of documentation, payer communication, and approval tracking to prevent delays and revenue loss.
Denial Management
Cardiology denials commonly result from coding errors, missing authorizations, or improper modifier application. Our denial management service reviews patterns, resubmits corrected claims, and appeals underpaid services. This reduces recurring deniels to 5% or less and helps recover lost revenue.
Payment Posting
Cardiology billing involves multiple service components, such as physician fees, facility charges, anesthesia, and technical/professional splits. We post payments accurately, reconcile accounts, and identify discrepancies for appeals.
Accounts Receivable (AR) Recovery
High-cost procedures in cardiology often lead to delayed payments and aging AR. In our AR Recovery Service we follow up on unpaid claims, resolve disputes, and appeal denials to shorten collection times and reduce write-offs.
Telehealth Billing
Cardiology telehealth services include follow-up visits, remote device checks, and virtual consultations. We apply correct telehealth place-of-service codes (02, 10) and modifiers (95, GT) to meet payer requirements and secure reimbursement under current policies.
Patient Billing Services
Cardiology patients often face significant out-of-pocket costs for advanced treatments. We in our patient billing service provide clear, easy-to-read statements, multiple payment options, and responsive billing support. This improves collections and patient satisfaction.
Practice Management Services
We provide back-office support for cardiology practices, including scheduling assistance, denial trend analysis, payer mix reporting, and physician productivity tracking. These practice management services improve daily operations and strengthen financial performance.
Old AR Cleanup
Cardiology practices often carry large amounts of old AR from expensive, complex procedures. Our AR cleanup services identify and pursue outstanding claims, recovering revenue that would otherwise be lost.
Appeals and Disputes Management
High-value cardiology procedures, such as ablations, stent placements, and device implants, are frequently underpaid or denied. We prepare detailed appeals, provide documentation, and track resolutions to secure full reimbursement.

Cardiology Coding Expertise by MZ Medical Billing
Cardiology billing depends on precise coding, as even minor errors can lead to denials or underpayments.

The American Medical Association (AMA) updates CPT codes annually, while insurers apply their own Local Coverage Determinations (LCDs) and NCCI edits. We stay up to date with all changes so your practice never misses charges or faces preventable denials.At MZ Medical Billing, we specialize in orthopedic billing and revenue cycle management.
