Cardiology Billing — Built for Your Practice
Cardiology billing runs on two different rule books — and treating them the same costs you money. Diagnostic studies like EKGs (93000) and echocardiograms (93306/93307) live and die on component-billing splits between the professional and technical sides. Cath-lab work — catheterization (93454–93461), stent placement (92920–92944), device implants (33206–33249) — carries high per-claim value, dense NCCI bundling, and 90-day global periods that decide what's billable next.
Most billing companies use one playbook for both. We don't.
Our cardiology coders are AAPC-certified and work cardiac claims exclusively. We know the three-way EKG split cold — 93000 (global), 93005 (tracing only), 93010 (interpretation only) — and we track every pacemaker and ICD's 90-day window and remote-monitoring frequency limits (93279–93299) automatically, so nothing slips through and gets denied.
What's Costing Cardiology Practices Money Right Now
These are the specific, avoidable spots where cardiology revenue quietly disappears before a claim ever gets appealed.
An EKG billed under the wrong split — global instead of -26, or the reverse — either bounces outright or leaves money on the table because it doesn't match who actually owns the equipment and who read the study.
A routine post-implant device check billed as a standalone office visit inside the 90-day global window gets denied automatically — one of the most common cardiology billing mistakes.
Remote device monitoring billed on a flat monthly schedule instead of the code's real 30- or 90-day period denies for a reason that looks random but isn't.
Advanced cardiac imaging or elective catheterization authorized through the payer's standard portal instead of the radiology benefit manager comes back with zero authorization on file.
Multi-vessel PCI add-on codes billed without correct primary/secondary sequencing get downcoded automatically, straight from the cath lab report.
NCCI bundling edits on cath-lab claims applied with a blanket modifier -59 instead of a genuinely distinct-procedure check invite an audit flag, not more revenue.
Top Cardiology Claim Denial Reasons — and How We Eliminate Them
Most Cardiology denials are preventable. Our team knows exactly what to look for before submission.
❌ Component Billing Mismatch on EKGs and Echocardiograms
Bill the wrong split and the claim bounces — or you leave money on the table. The right code (global, -26, or TC) depends on who owns the equipment and who reads the study, not what's convenient to bill.
✓ Our Fix
We confirm equipment ownership and the interpreting physician for every EKG and echo before charge entry — decided right the first time, not fixed after a denial.
❌ Global Period Violation on Post-Implant Device Visits
Bill a routine post-ICD check as a normal office visit and Medicare denies it — it's bundled into the implant for 90 days. Miss the reverse case and a genuinely unrelated visit gets bundled by mistake instead of billed with modifier -24.
✓ Our Fix
We track every device implant's 90-day window and flag each follow-up visit — bundled, -24, -78, or -79 — before the claim goes out.
❌ Remote Device Monitoring Billed Too Frequently or Without a Qualifying Baseline
Bill monitoring monthly when the code actually covers 90 days, or bill before the required in-person baseline, and the claim denies for a reason that looks random but isn't.
✓ Our Fix
We track each patient's device type, baseline evaluation date, and monitoring period, and hold every claim to the correct billing cadence.
❌ No Prior Authorization for Advanced Cardiac Imaging or Elective Catheterization
Request authorization through the payer's standard portal when a radiology benefit manager actually controls it, and you get no authorization on file — the claim denies in full.
✓ Our Fix
We identify which payers route advanced imaging through a radiology benefit manager and file through the correct channel, 48+ hours before the procedure.
Our Cardiology Billing Process, Start to Finish
Chart-to-Claim Coding Accuracy
Every EKG, echo, and cath-lab encounter is coded by cardiology-trained coders who confirm the correct global/-26/technical split and NCCI-compliant sequencing before the claim ever leaves the building.
Eligibility & Prior Authorization
We verify coverage and route advanced cardiac imaging and elective catheterization through the correct channel — payer portal or radiology benefit manager — filed 48+ hours before the procedure.
Global-Period & Bundling Compliance Audits
Every device implant's 90-day window is tracked and every cath-lab claim checked against the applicable NCCI edit before submission, with modifiers -24/-78/-79 applied only when the documentation actually supports them.
Denial Prevention & Recovery
Component-billing mismatches, global-period violations, and monitoring-frequency errors are caught before submission — and anything still denied gets tracked, corrected at the root, and appealed.
Reporting & Revenue Insights
A real-time dashboard shows your collection rate, denial trends, and outstanding claims by procedure type, so you always know exactly where your cardiology revenue stands.

What Sets ZenoMedix RCM Apart in Cardiology Billing
Not every billing company is built the same way. Here's what changes when your cardiology claims run through ours.
Cardiology-Trained Coders, Not Generalists
Our coders work cardiac claims exclusively and hold AAPC certification — they confirm equipment ownership and interpreting physician before assigning global vs. -26, and sequence every multi-vessel PCI claim from the cath lab report itself.
Every Denial Appealed, Never Written Off
100% of denials get tracked, corrected at the root cause, and appealed — a denied EKG or cath-lab claim is never just absorbed as a loss.
Pay Only When We Collect
Percentage-based pricing tied to what we actually collect for your practice, with no long-term contract locking you in.
Real-Time Visibility Into Your Revenue
A live dashboard shows your collection rate, denial trends, and outstanding claims by procedure type — no waiting on a monthly PDF to know where your cardiology revenue stands.
We Partner With Every Type of Cardiology Practice
General / Non-Invasive Cardiology
EKG and echocardiogram claims billed to the correct component split — global, -26, or technical-only — matched to who actually recorded and interpreted the study.
Interventional Cardiology / Cath Lab
Catheterization, PCI, and stent claims sequenced correctly under NCCI bundling rules, straight from the cath lab report.
Electrophysiology (EP)
Pacemaker and ICD implant claims tracked through the full 90-day global period, with the right modifier applied to every follow-up visit.
Cardiac Device & Remote Monitoring Programs

93000 is the global code — your practice performs the tracing and your physician reads it. 93005 is technical only — just the tracing, no interpretation, billed when a different physician (often elsewhere) reads it. 93010 is professional only — the interpretation of a tracing performed somewhere else. Bill the wrong one and the claim mismatches what actually happened. We confirm equipment ownership and the interpreting physician for every EKG and echo before we assign the code.
Implanting a pacemaker or ICD (33206–33249) opens a 90-day global period. Routine follow-up care and device checks in that window are bundled into the original payment — not separately billable. An unrelated visit needs modifier -24, an unrelated procedure needs -79, and a related return to the OR (like a lead revision) needs -78. Billing a routine post-implant check as a standalone charge is one of the most common cardiology denials we see. We track the window and apply the right modifier automatically.
Remote monitoring uses its own code family (93279–93299), separate from in-person device checks. Two rules matter: you need a qualifying in-person evaluation and physician order on file first, and each code has a fixed monitoring period — generally every 30 or 90 days depending on the device. Billing on a flat monthly schedule instead of the code's real period is a common, easy-to-miss error. We track both the baseline and the period for every patient.
Yes. Many payers route nuclear stress tests, cardiac CT/MRI, and sometimes elective catheterization through a radiology benefit manager — not their standard medical-policy portal. Request authorization through the wrong channel and you get no authorization on file, even though someone submitted a request. We identify the correct pathway per payer and file at least 48 hours before the procedure.
Angiography codes (93454–93461) already bundle standard diagnostic catheterization — contrast, imaging supervision, interpretation. When a PCI treats multiple vessels in one session, the add-on codes need correct primary/secondary sequencing, and modifier -59 or -XU only applies when it's a genuinely distinct procedure, not an extension of the same lesion. Our coders sequence every vessel from the cath lab report itself, never a blanket modifier.
