The #1 preventable revenue leak in medical practices
One cath-lab or device claim can be worth more than a week of office visits. We stop the revenue loss before they go out: a diagnostic cath billed without the CPT condition, a modifier that doesn't match the place of service.

90-day global on pacemaker and ICD insertion
3 conditions to bill a same-day diagnostic cath
2 units max on EP ablation add-ons
High-dollar cardiology claims get denied for three reasons. Cath-lab and EP (electrophysiology) coding, where the diagnostic cath is already bundled into the intervention. Device codes, where implants carry a 90-day global and monitoring carries its own time window. Modifiers, where you need to tell the payer who did which part and where it happened.
What it's costing you
Most claims in a cardiology practice are high-value and a denial poses serious threats to an efficient revenue cycle process. When a claim gets denied, the whole amount is stopped and a corrected claim is needed to get accurate payments. If a 26/TC or 59 modifier error pays, it comes back later as a recoupment.
~78.4%
of PCIs in stable multivessel or left-main patients were done in the same session as the diagnostic cath, so the cath line is a billing decision on most claims (8,196 PCI patients, New York State registries, 2018–2019).

potential Medicare overpayments from physicians coding facility services as nonfacility, Jan 2010–Sep 2012: the place-of-service error behind 26/TC.
33%
of 4,427 implanted-device patients in a 20-center remote-monitoring database were not being monitored at data cut-off, 2023: every unmonitored window is an unbilled 93294/93296.
Challenge 1
Deciding which main code fits the procedure, then checking whether anything is billable outside it. The main cardiology codes are containers: a left heart cath (93458) already includes placing the catheter, injecting the dye and taking the images, and an AF ablation (93656) includes 3D mapping, intracardiac echo and the transseptal crossing since 2022.
01
The note does not state a CPT condition for a separate diagnostic cath. “Known lesion from last month’s cath” is none of them, and the cath line is edited off.
02
The charge template still adds 3D mapping (93613) and intracardiac echo (93662) to every AF ablation. Those are inside 93656 now, and no modifier fixes the edit.
03
93657 means additional AF lesions after the pulmonary veins were isolated. It belongs only with 93656. On an SVT ablation (93653) it denies every time.
04
Payers cap the units of a code they accept in one day. For 93655 and 93657 the cap is 2. A third unit denies no matter what the note says.
The extra line is removed and the main line is often held while the payer asks for records, so a large claim waits. The worse case does not look like a loss at first: a 59 or XU modifier forces the cath line through, the claim pays, and months later the payer finds no condition in the note and takes the money back.
1
Put the CPT condition in the cath note template as a required field, in the physician’s words.
2
Rebuild EP charge templates on the 2022 bundles so 93613, 93662 and 93621 cannot be added to 93653 or 93656.
3
Allow 93657 only on 93656 in the charge-entry rules, and cap add-on units at the MUE unless a coder overrides with documentation.
4
Run NCCI edits on every cath-lab claim before submission and refresh the tables each quarter.
Challenge 2
Two problems that look the same on the claim. First, codes that already include work billers keep adding back: a generator replacement (33227–33229, 33262–33264) includes removing the old one, and a complete echo (93306) includes the Doppler add-ons. Second, remote monitoring, billed in time windows: one physician charge (93294 or 93295) and one technical charge (93296) per window of up to 90 days.
The smaller line denies and the larger line waits. Monitoring is the quieter loss: when a window is missed, nothing is billed, so nothing is denied, and no report ever shows it. The same revenue leaks again every quarter until someone builds the calendar.
1
Map every replacement code to “includes removal” in the charge master.
2
Lock the echo and stress templates so included components cannot be added.
3
Give each device patient a monitoring calendar: window start, window end, one physician charge and one technical charge per window.
4
Record who bills 93296 for each monitoring vendor, in the billing system, not in the contract file.
01
33228 and 33233 go out on one claim for one generator change. The removal line is denied, and the replacement line is often held until the claim is corrected.
02
93320 or 93325 on a complete echo, 93017 on a stress echo. The component denies, and the pattern tells the payer the templates are wrong.
03
93294 is billed on day 1 and again on day 45 for the same pacemaker. The descriptor says up to 90 days, so the second is a duplicate.
04
The practice and the monitoring vendor both bill the technical charge, or neither does. The vendor contract says who bills it, and most contracts are not in the billing system.
Challenge 3
The three modifiers that most often decide whether a high-dollar cardiology claim pays correctly. 26 says the physician only read the test, as with echo and nuclear studies on hospital equipment. 57 says the visit was the decision for a 90-day-global surgery such as a pacemaker or ICD implant. 59, or the X modifiers Medicare prefers, says a normally bundled service was separate this time.
01
An echo read in hospital outpatient is billed as the global code instead of 93306-26. It pays, then the payer matches it against the hospital’s technical claim and takes the money back.
02
The visit where the cardiologist decides on a pacemaker goes out with modifier 25 by habit. A 90-day global needs 57. With 25, the visit is treated as part of the surgery and drops.
03
On the cath-plus-stent pair, 59 or XU is right only when one of CPT’s conditions is in the note. Added just to get the claim through, it pays now and is audited later.
04
A visit 20 days after an ICD with no 24 is bundled into the surgery. A lead revision with no 78 is bundled. Modifier 22 with no explanation draws a records request.
25/57 and 24/78/79 errors drop the visit or the procedure, and those at least show up as denials. 26 and 59 errors are the expensive kind. They pay first, then come back months later as recoupments and audit letters, in a month when nothing else went wrong.
1
Let place of service decide 26, TC or global at charge entry, not the coder’s memory.
2
Key 25-or-57 to the procedure’s global period: 0 days means 25, 90 days means 57.
3
Prompt for 24, 78 or 79 on any visit or procedure inside an open 90-day global. on any visit or procedure inside an open 90-day global.
4
Prompt for 24, 78 or 79 on any visit or procedure inside an open 90-day global.
How MedCare MSO fixes it
One cardiology billing team, one workflow, with the Orbis AI ecosystem doing the tracking that spreadsheets cannot.
Sophus reads the cath report for the CPT condition before 93458 goes on a PCI claim and builds EP charges on the 2022 bundles. Cath-lab claims go to a certified coder for sign-off.
Maximus carries the monitoring calendar per device patient and the vendor contract for 93296; replacement and echo templates are locked to their bundles.
Consus derives 26/TC/global from place of service, 25-or-57 from the global indicator, prompts 24/78/79 inside an open global, and flags 59/XU with no condition on file. Paid 26 and 59 claims are audited quarterly.

Questions
Yes, but there is only one condition in which it can be done. There was no catheter-based angiography in the past and the decision to intervene is taken from today’s study or a prior study is there but the patient’s condition changed. The anatomy was not seen adequately enough. Or there is a new evaluation required outside the target area due to a clinical change during the procedure. The note should contain what happened. Otherwise the angiography is part of the PCI.
The year 2022 is important here. Since CPT 2022, AF ablation code contains these: 3D mapping (93613), intracardiac echo (93662), transseptal catheterization and atrial and ventricular pacing/recording. The same bundling applies to 93653 for 3D mapping and LA pacing. The only add-ons left are 93655 and, for 93656 alone, 93657.
The global period of the procedure decides this. Pacemaker and ICD insertion have a 90-day global period. So, the E/M visit where the decision was made takes the -57 modifier. There is a 0-day global for Cath, PCI, echo and device interrogation. So, -25 modifier is used for a separately identifiable E/M on the same day. Using -25 modifier on the day of an implant drops the visit.
For the technical remote interrogation charge for a pacemaker or ICD, 93296 is used. One technical and one professional charge (93294 or 93295) for one window. The monitoring contract shows that which party submits 93296. If both parties do, the second is a duplicate.
The place of service code tells the payer who owned the equipment. Hospital outpatient setting (place of service 22) means the facility owns it and bills the technical component, so the physician bills 93306-26. In the office (place of service 11) the practice owns the equipment and bills the global code with no modifier. The place of service on the claim has to match, or the claim is denied, or paid wrong and recouped later.
A cardiology billing audit reviews your recent cath-lab, EP and device denials, names the rule behind each one, and shows what can still be recovered.
