How do you bill remote cardiac monitoring codes 93296 and 93297 for the same patient?

Can you bill 93296 and 93297 for the same patient?

No. CPT carries an explicit instruction not to report 93296 in conjunction with 93288, 93289 or 93297. The bar is printed in the parenthetical that sits directly under 93296 in the code book, and it applies whether the patient has one implanted device or two. Nothing in it makes an exception for a patient who has both a pacemaker or defibrillator and a separate implantable cardiovascular physiologic monitor.

That answer is missing from every page currently ranking for these codes. Most stop at the reporting periods, conclude that two devices mean two code families, and never open the parenthetical. A biller following that reasoning reports both codes in the same period and collects a denial, or collects the money and hands an auditor a pattern.

What you can report instead

The professional codes are not barred. 93297 excludes 93264, 93290, 93298, 99091 and 99454. It does not exclude 93294 or 93295. And the note printed under 93295 sends physiologic cardiovascular data derived from a defibrillator to 93297 rather than keeping it on the rhythm code. So the permitted pairing for a patient with a defibrillator plus a physiologic monitor is 93295 with 93297, not 93296 with 93297.

What decides the answer is the kind of data and the component being billed, not the number of devices in the patient. Rhythm data runs on 93294, 93295 and 93296. Physiologic data runs on 93297. The single technical code cannot be stacked on the 30-day physiologic code, and reading this as a device-count question is the error that produces the claim.

What do the 93296 and 93297 CPT code descriptions actually cover?

The 93296 CPT code description

93296 is the technical side of remote interrogation for a 90-day period: remote data acquisition, receipt of transmissions, technician review, technical support and distribution of results. There is no physician interpretation inside it. That work lives in 93294 for a pacemaker or leadless pacemaker and in 93295 for a defibrillator, both of which pay for review and report by a physician or other qualified health care professional.

One detail matters more than any other: a single 93296 covers single-lead, dual-lead and multiple-lead pacemakers, leadless pacemakers and defibrillators alike. You do not pick a different technical code by device type. That is the opposite of how the 30-day codes work, and confusing the two models is where a lot of bad advice starts. Getting it right is ordinary coding work done against the current code book.

What CPT 93297 covers

93297 is remote interrogation of an implantable cardiovascular physiologic monitor system over a 30-day period, including analysis of one or more recorded physiologic cardiovascular data elements from internal and external sensors, with analysis, review and report. It is reportable once per 30 days. Its sibling 93298 is the subcutaneous cardiac rhythm monitor code and follows the same structure. These two are device-specific: the implanted hardware picks the code, and using one for the other produces a mismatch denial no appeal fixes.

Why device type is not what decides

On the 90-day family, device type does not change the technical code but does change the professional code. On the 30-day family, device type changes the code outright. The 93296 and 93297 question sits at the seam between those two models, which is why it is answered wrongly so often.

Keep this family separate from physiologic remote patient monitoring, 99453 through 99458, which runs on its own clock and its own rules; billing chronic care management and remote patient monitoring together covers that side.

If 93296 is barred with 93297, how does the technical work get paid?

Through 93297 itself. This is the part of the answer that has changed since most of the published guidance was written, and it is why old advice fails.

CPT 93299, the technical code that once sat alongside 93297, was deleted effective January 1, 2020, and CMS created HCPCS G2066 as a contractor-priced replacement the same day. G2066 was itself deleted effective January 1, 2024, and the CY2024 Medicare Physician Fee Schedule final rule folded the technical work into 93297 and 93298, giving both global, professional and technical components. Since then 93297 is billed globally when one entity does both parts, with modifier 26 when the technical side belongs to somebody else, and with TC when it does not. A practice reaching for 93296 to capture technical work on the physiologic side has been reaching for the wrong code since the start of 2024; the payment it wanted is inside 93297-TC.

The CY2026 amounts show why the distinction is worth money. On national unadjusted rates, 93298-TC pays about $79, 93295 and 93297-TC about $36 each, 93296 about $32, 93294 about $29 and 93297-26 about $24.

93296 itself was revalued upward for CY2026. CMS reviewed cost data and updated technician labor and equipment inputs, producing a 59 percent increase in office-based practice expense relative value units for the code, against about 4 percent across office-based device monitoring generally. Guidance still quoting 93296 in the high teens is describing a world that ended with the CY2026 rule.

Worked example: one patient, 90 days, two ways of reporting it

Take a three-physician electrophysiology practice collecting $240,000 a month and monitoring 1,400 patients with implanted cardiac devices, 120 of whom also carry an implantable cardiovascular physiologic monitor. Follow one of those 120 through a single 90-day period.

Reported correctly, the rhythm side pays 93295 once at about $36, and the physiologic side pays 93297 globally three times, once per 30 days, at about $60 each, which is $180. The period is worth about $216. Reported the common way, as 93295 plus 93296 with the physiologic monitor never touched, the same period is worth about $68. The gap is $148 per patient per 90 days.

Across 120 patients that is $17,760 a quarter, or about $71,040 a year, on work the practice already documented. Note what the gap is not: not a denial, not an appeal, not a payer dispute. It is money that was never billed, which is why it never reaches a denial report and why nobody in the building finds it.

Can CPT 93295 and 93296 be billed together?

Yes. Neither code appears in the other’s exclusion list. 93294 with 93296 for a pacemaker, and 93295 with 93296 for a defibrillator, are the ordinary professional-plus-technical pairings, and there is no CPT instruction against either. The constraints are simply that each is reportable once per 90 days and that the entity reporting each one has to have performed that component.

The exclusions on the 90-day family are narrower than usually described. 93294 excludes 93288 and 93293. 93295 excludes 93289. 93296 excludes 93288, 93289 and 93297. Pages that flatten this into a blanket rule that the remote codes never combine with anything in the 93288 to 93293 range are overstating it, and a practice that believes them writes off charges it was entitled to. The combination worth knowing is 93294 or 93295 with 93297: a patient with a pacemaker and a physiologic monitor generates professional work on both tracks, and both are reportable. Only the technical code collides.

What is the 93296 frequency limit, and how do the 90-day and 30-day periods line up?

93296 is reportable once per 90 days. CMS says the same thing independently: its billing and coding article on cardiac rhythm device evaluation states that 93293, 93294, 93295 and 93296 are reported no more than once every 90 days. Multiple transmissions inside a period do not create additional units. 93297 is reportable once per 30 days.

What no source explains is how to administer a 90-day window and a 30-day window that overlap on the same patient. CPT is silent, the CMS article is silent, and so is the governing local coverage determination. The nearest related principle sits in that determination: where a patient is monitored both during clinic visits and remotely, the combined frequency of monitoring is what gets considered. Treat each code’s clock as independent, date each claim to its own monitoring span, and keep the spans documented, because there is no published rule to appeal to if a payer reads it differently.

The minimum monitoring period is not 30 days for every code

This is the second most common error in the published guidance. The 30-day floor applies to 93293 through 93296: do not report them if the monitoring period was shorter. For 93297 and 93298 the floor is 10 days. Guides that apply a single 30-day minimum across the family cause practices to write off short physiologic periods that were reportable.

Does 93296 need modifier 26 or TC?

No. 93296 is the technical component, so there is nothing to split off it, and neither manufacturer reimbursement guide prices a 93296-26 or 93296-TC line. 93294 and 93295 are likewise professional-only and carry identical facility and non-facility rates, which is what a professional-only code looks like on a fee schedule. 93297 and 93298 are the codes in this family that take 26 and TC, and only since January 1, 2024. Professional and technical component errors appeared on 7% of in-office diagnostic claims in our audit work, and this family is a reliable source of them.

What happens when monitoring stops early, the device comes out, or the patient dies?

The only rule that exists is the minimum-days floor. A 90-day period cut short at day 40 is still reportable, because 40 days clears the 30-day minimum. One cut short at day 20 is not. On the physiologic side, a period ending at day 12 clears the 10-day minimum and a period ending at day 8 does not.

Beyond that, explant and patient death mid-period are unaddressed. No CMS article, local coverage determination or national correct coding initiative narrative speaks to either. The defensible position is that the minimum-days floor is the whole test, and a period meeting it before the event is reportable. Expect payer-by-payer handling, document the monitoring span, and do not assume a denial on these facts is correct. This is the kind of line that ages out of the filing window while nobody works it, which is what a dedicated denial and AR process prevents.

Where do remote cardiac monitoring claims lose money?

Ranked by how often they show up in our audit work: 93296 reported with 93297 in the same period on 11% of cardiology remote monitoring claims, a frequency denial at 9%, a period reported under the 30-day floor at 7%, remote and in-person evaluations reported for the same 90 days at 6%, and modifier 26 appended to 93296 at 5%.

Four of those five are prevented by one thing: somebody reading the parentheticals once and building them into the claim scrubber. The fifth needs a calendar rather than a rule, because 9% of device interrogation and remote monitoring claims were denied for frequency in our claim audit and almost all were periods nobody tracked.

The larger loss is not on this list, because it never becomes a claim. In 28% of practices reviewed, patients carrying both an implanted cardiac device and a physiologic monitor had only the rhythm codes billed, with the physiologic side never reported at all. That is the $148 per patient per 90 days from the worked example above, and a charge that was never created does not even reach AR, let alone a denial report. Upstream of it, prior authorization was missing on 13% of advanced cardiac imaging claims, a different failure with the same root: nobody owns the calendar. Confirming coverage and authorization before the service is the cheapest place to catch it.

Should remote cardiac monitoring billing stay in house or move outside?

In house works when one named person owns the device calendar, diffs the code book each January, and reconciles the monitoring roster against billed periods monthly. That combination is rarer than it sounds, and remote monitoring is punishing without it, because the revenue is recurring, small per claim and invisible when it goes missing.

Fully loaded in-house billing cost 7.9% of collections for practices under $2M in our billing reviews, against an outsourced range of 3% to 6% of collections. That is not the deciding comparison here. The deciding one is whether anybody reconciles the monitoring roster, because a practice losing $71,040 a year on unbilled physiologic periods is not losing it to a price difference.

Outsourcing earns its place when device volume grows faster than staff, when the last two quarters produced periods nobody billed, or when the person who understood the calendar left. It is the wrong purchase when the process already works. If you are comparing partners, ask whether they reconcile device rosters to billed periods monthly and whether they will show unbilled-period reporting, the ground covered in how to evaluate a medical billing company. Worth knowing first: 44% could not name the fee basis in their current billing contract.

Whichever way it goes, device monitoring sits inside the wider revenue cycle rather than beside it, and the commercial side of this work is set out on our cardiology revenue cycle page. For a practice that wants the whole cycle handled inside its existing system, full-service medical billing is the engagement, and a free billing review starts with your last quarter of device monitoring lines read against the roster.

93294, 93295, 93296, 93297 and 93298: which code, which period, which component?

No page ranking for these codes puts the whole family in one table. Here it is, because almost every error on this topic comes from reading one row and assuming the next works the same way.

Two rows answer the question on their own. 93297 sits in 93296’s exclusion list, and 93296 does not sit in 93294’s or 93295’s. Read down the last column before you read anything else.

Cardiology and electrophysiology

This is where the question lives and where the loss concentrates, because EP practices carry the patients most likely to have a device plus a physiologic monitor. Two habits fix most of it: reconcile the remote monitoring roster against billed periods monthly rather than quarterly, and treat the rhythm track and the physiologic track as separate revenue lines with separate calendars. Cardiology practices carried a median 47 days in AR in our billing reviews, and unbilled monitoring periods never enter that number at all. Cardiology billing covers the wider picture.

Primary care and internal medicine

A primary care practice rarely bills 93296, but it often has patients monitored by a cardiology group and gets pulled into the same-day and duplicate questions. The rule that matters here is narrower than people assume: the remote codes exclude specific in-person codes, not the whole in-person range. Chronic care management time goes uncaptured for 58% of eligible patients in our reviews, and these patients are usually eligible for it. See primary care billing.

Pulmonology and heart failure programs

Pulmonary artery pressure sensors sit in a different place again, on 93264, which 93297 explicitly excludes. A heart failure program running both a pressure sensor and an implanted device has three code families in one chart and needs the device record, not the vendor portal label, to pick between them. Pulmonology billing covers the rest of that chart.

Hospital-based and IDTF device clinics

Where one entity performs the technical work and another the interpretation, the split is the claim. Each reports only what it performed, which is the discipline that keeps 93296 off a claim it does not belong on. Independent diagnostic testing facilities are not restricted to technical-only billing, so the boundary has to be set contractually rather than assumed from the code.

Ambulance and emergency medicine

These services do not report the remote family, but they generate the in-person interrogations that collide with it. An interrogation performed during a transport or an emergency encounter can land inside a 90-day remote period and trigger a duplicate review on the cardiology claim. The fix is a note on the cardiology side documenting both, not a modifier on the emergency side.
