Cardiology Billing Services | Echo, Cath, Device Monitoring | Quilven RCM
Specialty · Cardiology

Two codes per study. One gets billed.

Cardiology billing lives on the modifier. 26 versus TC on every echo. Device monitoring billed monthly or not at all. Global period E/M denied without modifier 24. The interpretation is done. The procedure is done. The claim is where the cycle leaks.

The cardiology billing problem

Most cardiology revenue leaks on the modifier.

A cardiologist reads an echocardiogram at the hospital. The interpretation is sharp, the report goes to the referring physician, the patient gets the right treatment. Three weeks later the claim goes out as 93306 global. The hospital separately bills 93306 TC. Both claims get denied. The practice and the hospital both submitted for technical component revenue that only one of them can claim. The right code was 93306-26, professional component only. About 70 dollars instead of 230 dollars per study. Across 150 echoes a month, the modifier error is around 90 thousand dollars a year. Walking out the door.

That is one leak. Device monitoring is the second. A typical cardiology practice has 200 active pacemaker patients, 100 ICD patients, and 50 loop recorder patients on remote monitoring. The codes are 93294, 93295, and 93298. They bill monthly or every 90 days depending on the device. Done correctly the device monitoring queue is a 60 thousand dollar a year recurring revenue line item. Most practices either do not have the queue built, or they bill in-person interrogations and skip the remote codes entirely.

Global period E/M is the third. Diagnostic catheterization has a 0-day global. Stent placement and EP ablation have 90-day globals. During the global period, any E/M visit related to the procedure is bundled. An E/M visit unrelated to the procedure requires modifier 24 to bill separately. Without modifier 24, the claim denies. With modifier 24 properly documented, the visit pays. Most cardiology practices miss 30 to 50 percent of legitimate modifier 24 opportunities because the workflow does not flag global periods at scheduling.

These are not coding mistakes. They are workflow problems. The studies happen. The procedures happen. The billing is wrong because nobody is reading the place of service against the modifier and the global period against the next visit. That is the work we do.

Side by side

Same cardiology practice. Two outcomes.

What a percentage based billing vendor delivers versus what a managed department delivers. The economics drive every decision about which functions run.

Typical cardiology vendor

Paid for claims submitted. Not collected.

  • Modifier 26 vs TC applied by template default. Hospital site studies billed globally and denied.
  • Device monitoring queue not in workflow. Pacemaker, ICD, loop recorder monthly revenue never starts.
  • Global period E/M denied without modifier 24. Practice writes off the visit.
  • NCCI edits flagged by clearinghouse but not corrected. Denials accepted as final.
  • Prior authorization for cath and EP handled by clinical staff, not the billing vendor.
  • Diagnostic catheterization plus same-day intervention codes bundled. Stacking not pursued.
  • Aged AR on high-dollar procedures over 90 days quietly written off.
  • Credentialing tracks payers but not hospital privileging. Non-billable months not flagged.
Quilven · Department model

Paid to own the whole cycle.

  • Certified coder reviews place of service against modifier on every imaging study. POS 22 stays modifier 26.
  • Device monitoring queue billed monthly without exception. 93294, 93295, 93296, 93298 by device type.
  • Global period tracking built into scheduling. Modifier 24 applied when documentation supports it.
  • Monthly NCCI edit review against current CMS quarterly update. Bundling errors corrected before submission.
  • Prior authorization workflow for cath, EP, device implant. Submitted, followed up, escalated when delayed.
  • Same-day diagnostic plus intervention coded with proper sequencing. Add-on codes captured.
  • AR over 90 days on procedural claims worked first. Appeals to round three or four when math justifies.
  • Hospital privileging tracked alongside payer credentialing on a live master sheet.

Question 01 of 08
Common questions

Cardiology billing, answered straight.

The questions practice administrators actually ask before signing with a billing company.

The best billing service for a cardiology practice is one structured around the codes that actually drive cardiology revenue. That means modifier 26 versus TC accuracy on every echo, stress test, and nuclear study, cardiac device monitoring billing for pacemakers, ICDs, and loop recorders, global period E/M management with modifier 24, NCCI edit review on every catheter and stent code, and prior authorization tracking for cath and electrophysiology procedures. Quilven runs all of these as a managed department, not a percentage of collections service.
Modifier 26 (professional component) and modifier TC (technical component) split a global service. The professional component is the interpretation and report. The technical component is the equipment, supplies, and technician time. When a cardiologist interprets a study performed at a hospital they do not own, the practice bills the global CPT code with modifier 26. The hospital bills the same CPT with modifier TC. When the study is performed in the cardiologist's own office with their own equipment, the practice bills the global code with no modifier. For an echo (93306) the global pays approximately 230 dollars, modifier 26 pays approximately 70 dollars, and modifier TC pays approximately 160 dollars.
Cardiology bills E/M codes (99202 through 99215), non-invasive diagnostic codes (93000 ECG, 93010 ECG interpretation only, 93306 complete echo, 93308 limited echo, 93350 stress echo, 93880 carotid duplex), stress testing (93015 through 93018), nuclear cardiology (78451 through 78454), left heart cath (93452 through 93461), interventional procedures (92920 PCI, 92928 stent, 92933 atherectomy, 92937 CTO), EP studies (93619, 93620, 93653, 93656), device implant (33206, 33207, 33208, 33249), cardiac device monitoring (93279 through 93298), and modifiers (26, TC, 24, 25, 59).
Cardiac device remote monitoring billing is monthly recurring revenue for cardiology and one of the most commonly missed line items. Pacemaker remote: 93294 (single chamber, every 90 days) approximately 30 dollars. ICD remote: 93295 (every 90 days) approximately 40 dollars. Implantable loop recorder: 93298 (every 30 days) approximately 30 dollars. A panel of 200 pacemaker patients billed correctly generates around 24 thousand dollars per year. A panel of 100 ICD patients generates 16 thousand dollars per year. Loop recorder monitoring at 30 dollars monthly across 50 patients adds another 18 thousand dollars annually.
Many cardiology procedures carry a global period during which routine follow-up E/M visits are bundled. Diagnostic cath typically has a 0-day global. Stent placement and EP ablation have 90-day globals. During the global period, an E/M visit unrelated to the procedure requires modifier 24 to bill separately. Common scenarios that justify modifier 24 include unrelated cardiac conditions, new symptoms unrelated to the stented vessel, or management of a different chronic condition. Without modifier 24, these E/M visits are denied. Cardiology practices typically miss 30 to 50 percent of legitimate modifier 24 opportunities.
93306 is a complete transthoracic echocardiogram with spectral and color Doppler. Includes 2D imaging, M-mode, spectral Doppler, and color flow of all four chambers and great vessels. 93308 is a limited or follow-up echocardiogram. Covers focused studies. 93306 pays approximately 230 dollars globally (70 dollars modifier 26, 160 dollars TC). 93308 pays approximately 100 dollars globally. The clinical decision drives the code: complete evaluation is 93306, focused follow-up is 93308.
The National Correct Coding Initiative (NCCI) edits identify code pairs that should not be billed together. Cardiology has more NCCI edits than almost any specialty. Common patterns include catheter placement codes bundling with imaging codes, stent placement bundling with the diagnostic cath, multiple stent codes in the same vessel (only one primary stent per vessel, secondary stents use add-on codes), and add-on codes that require specific base codes. A coder rule and monthly NCCI review against the current CMS quarterly update is the only reliable way to catch them. NCCI errors typically cost a cardiology practice 5 to 8 percent of high-dollar procedural revenue annually.
Cardiology credentialing typically runs 120 to 240 days from start to billable, longer than primary care because of hospital affiliations. A new cardiologist usually needs credentialing with multiple commercial plans (90 to 120 days), Medicare (60 to 90 days), state Medicaid (varies, 60 to 180 days), and hospital privileging at every facility where they will perform procedures (60 to 180 days per hospital, runs in parallel). The cost of a non-billable cardiologist runs approximately 60 thousand to 90 thousand dollars per month depending on procedure mix.
Quilven offers a free 48 hour billing audit with no commitment. The practice sends 90 days of claims data. Within 48 hours, Quilven returns a line by line breakdown showing what is recoverable by CPT code, by payer, and by month. Common cardiology findings include modifier 26 versus TC errors on echo and stress test studies, cardiac device monitoring not billed monthly, global period E/M denied without modifier 24, NCCI bundling errors accepted as final, and aged AR over 90 days on high-dollar procedural claims written off prematurely. The practice keeps the findings whether or not they engage Quilven for managed RCM services.
Typical cardiology billing companies charge 5 to 8 percent of collections. On a high-dollar procedural claim that pays 2,500 dollars, the vendor earns 125 to 200 dollars and the math works. On a 93294 pacemaker remote interrogation paying 30 dollars, the vendor earns under 2 dollars and the math does not work. That drives every decision. Quilven operates as a managed department with a flat operational model that includes the work percentage based vendors skip. Practices get certified coder review on every modifier 26 versus TC decision, device monitoring billed monthly, global period tracking, monthly NCCI review, denial recovery to round three or four, aged AR worked first, and live dashboard reporting through the Quilven Apex platform.
About Quilven

The billing department for cardiology.

Quilven is a managed revenue cycle management company based in Nashville, Tennessee. We provide end to end medical billing services for cardiology practices, electrophysiology groups, interventional cardiology, nuclear cardiology, primary care, internal medicine, behavioral health, and community hospitals across the United States.

The company runs a managed department model rather than a percentage of collections billing service. The structural reason matters. Vendors paid 5 to 8 percent of collections optimize for high-dollar procedural claims. They skip the work that does not pay them, which in cardiology is most of the modifier accuracy, device monitoring, and global period management. That includes modifier 26 versus TC review on every imaging study, cardiac device monitoring for pacemakers, ICDs, and loop recorders, global period E/M with modifier 24, NCCI edit correction, prior authorization for cath and EP procedures, and aged AR over 90 days on high-dollar claims.

Cardiology billing under the Quilven model includes place of service audit against modifier on every imaging study (93306, 93308, 93350, 93880, 78452, others), device monitoring queue billed monthly without exception, global period tracking at scheduling with modifier 24 applied when documentation supports it, monthly NCCI review against the current CMS quarterly update, prior authorization workflow for cath, EP, and device implant, denial recovery to round three or four when the dollar amount supports it, aged AR on procedural claims worked first in the morning queue, and provider credentialing tracked alongside hospital privileging on a live master sheet.

The company is HIPAA compliant. Business Associate Agreements are available on request. Quilven works with practices on any EHR platform including Epic, eClinicalWorks, NextGen, AdvancedMD, Athenahealth, Greenway, Cerner, and Practice Fusion.
