Meta description: 5 remote monitoring billing mistakes costing cardiologists their revenue in 2026 and how a cardiology billing company helps you fix them and get paid.
Are you aware that as per a HHS Office of Inspector General data snapshot, in 2024, Medicare spent a total of $536 million on remote patient monitoring, an increase of 31% compared to the previous year. Additionally, close to one million Medicare beneficiaries participated in RPM, representing a 27% rise. This information tells you two things at once: remote monitoring has become real revenue, and it is now under real scrutiny. Simply put, while the growth of RPM presents significant revenue opportunities for cardiologists, the billing side may not be so easy.
A wrong CPT code, thin documentation, a claim submitted a few days too early, RPM and cardiac device interrogation lumped together as if they are the same service; any one of these can turn a legitimate service into a denial. Practices that lean on an experienced cardiology billing company tend to catch these before they become a pattern.
Mistakes an Expert Cardiology Billing Company Fixes
1. Treating RPM and Cardiac Device Interrogation as the Same Service
Remote patient monitoring and cardiac device interrogation are not the same, and the codes make that clear. Remote patient monitoring devices can be coded using CPT codes 99453, which denotes initial setup and patient education of the RPM device, and 99454, which denotes the monthly supply of an RPM device and the electronic transmission of patient health data. Apart from these, there are also 99457 and 99458, along with two additional codes that CMS recently introduced in 2026, CPT 99445 and 99470, reducing the old time frame so even shorter remote monitoring periods can still get reimbursed.
Cardiac implantable electronic device (CIED) monitoring for pacemakers, ICDs, and loop recorders uses an entirely different set of codes, CPT 93294 through 93298.
The dollar amounts differ too, which is exactly why the distinction matters operationally. On the RPM side, national average rates for 2026 are around $22 for initial setup (99453), $47 for device supply (99454, which has now been grouped with the new low-threshold code 99445), $52 for the first 20 minutes of monthly treatment management (99457), and $41 for each subsequent 20 minutes (99458). Imagine billing for these codes together for 100 patients, and the revenue opportunity that comes with it.
On the CIED side, the payment amount and rules will be completely different. A knowledgeable cardiology billing company builds workflows around device type, RPM versus interrogation, professional versus technical component, the service period, and payer-specific rules, and not a single generic remote monitoring bucket.

2. Billing Without Documentation That Supports the Code
It is customary that the diagnosis code must support medical necessity, and the CPT/HCPCS code must match the service performed, not the service that was theoretically available. For CIED monitoring, that means device status, findings, and physician interpretation need to be on the record. For RPM, it means eligibility, consent where required, device use, and actual data transmission, tied to real treatment-management time.
This is where the OIG’s scrutiny gets concrete. An earlier OIG review found that 43% of beneficiaries receiving RPM had not received all three commonly billed RPM components: setup and education, device supply, and treatment management. Such billing patterns may attract additional scrutiny, although they do not by themselves establish that an overpayment or violation occurred. A useful documentation workflow answers a short list of questions before the claim goes out:
- Why was the patient monitored?
- What device generated the data?
- Who reviewed it and what did they decide clinically?
- Does the note actually support the code on the claim?
A seasoned cardiology billing company can build that checklist into a pre-billing audit instead of finding the gap during a payer review.
3. Getting the Frequency Rules Wrong
CPT 93295 and 93296 are generally billed once per 90-day period, no matter how many interrogations happen within that window, and an in-person check during the same period usually gets folded into the remote service rather than billed on its own. Interestingly, CMS leaves the timing judgment to the treating physician under National Coverage Determination 20.8.1; the 90-day window is more of a guardrail than a strict rule. In practice, most frequency errors come down to a simpler problem: a practice that is not tracking device-transmission dates closely enough to know when a new billing period has actually opened.
The obvious risk is overbilling, meaning treating every alert as its own claim. But undercoding causes just as much damage and gets talked about far less. Defaulting to the safer side, even when the documentation justifies the higher level of coding, can lead to lost revenue each time without ever getting a denial to alert about it. Identifying both sides of the issue requires continuous monitoring, which is sometimes hard for most in-house billing departments.
4. Blurring the Professional and Technical Components
Remote cardiac monitoring routinely involves more than one person doing more than one kind of work. The professional component, meaning the physician or qualified health care professional’s analysis, interpretation, and reporting, is billed separately from the technical component. The technical component covers data acquisition, transmission receipt, technician review, and distribution of results.
CMS assigns 93294 specifically to the professional work on remote pacemaker interrogation and 93296 to the technical side; for ICDs, 93295 and 93296 follow the same professional/technical split. One detail that confuses practices is that 93296 can only be billed by the physician practice if the physician personally performed the technical service or employs the staff member who did. However, if a device-company representative handled that piece, the practice can only bill the professional side.
Miss it and you get duplicate claims, incorrect modifier use, payer edits, or quiet underbilling. Mapping the clinical workflow and identifying who provided what service is exactly the kind of detail a specialized cardiology billing company is built to catch.
5. Not Tracking Denials as a Revenue Signal
A submitted claim does not mean a settled claim. Common reasons for remote monitoring denials all fall under one or a few common grounds: necessity, frequency limitations, coverage policy, coding mistakes, missing documents, and each requires a different corrective action. The most important thing to develop is the ability to notice trends instead of dealing with individual denials as separate issues. If a particular payer rejects the same code repeatedly for the same reasons, there is something to investigate further.
This matters more than usual right now. Oversight of remote monitoring billing has shifted from cautionary guidance to active enforcement, and regulators have shown they are willing to follow through. Denial tracking is not just about recovering revenue anymore; it has become an early-warning system for spotting compliance risk before it turns into something bigger for an expert cardiology billing company.
