CPT Codes for Remote Patient Monitoring Explained
Remote Patient Monitoring (RPM) has quickly become one of the most valuable digital health services in the United States. Across major cities like New York City, Los Angeles, Chicago, Houston, and Dallas, more clinics are turning to RPM billing for chronic conditions to track patients’ vital signs, manage chronic conditions, and improve outcomes without requiring constant in-person visits. By using connected devices and secure data sharing, doctors can keep a close watch on patients while reducing hospital readmissions and improving daily care.
For physicians and billing teams, understanding CPT codes for remote patient monitoring billing is essential. These codes are what allow providers to accurately report services, ensure proper Medicare reimbursement for RPM, and maintain compliance with CMS rules. Without correct coding, clinics risk claim denials, reduced revenue, and even compliance issues during audits.
There are four primary RPM CPT codes for remote patient monitoring billing that every practice should know:
- 99453: Initial patient setup and education.
- 99454: Device supply and data transmission.
- 99457: First 20 minutes of monitoring and care management.
- 99458: Each additional 20 minutes of monitoring.
Each code covers a specific part of the remote patient monitoring billing process, from onboarding patients to ongoing communication and device use. Using them correctly helps practices maximize reimbursement while ensuring patients receive consistent, high-quality care.
At SmartCare360, we focus on supporting doctors and clinics with tools that simplify how to bill remote patient monitoring billing services.

In the sections ahead, we’ll break down these codes in detail, explore billing workflows, and highlight how clinics across the USA can benefit from accurate RPM documentation and billing.
What Are CPT Codes for Remote Patient Monitoring Billing?
In healthcare billing, Current Procedural Terminology (CPT) codes are the standardized numbers used to describe medical, surgical, and diagnostic services. For doctors and billing teams in the United States, CPT codes for remote patient monitoring billing are the key to ensuring accurate reimbursement, transparent documentation, and compliance with Medicare reimbursement for RPM and commercial payer requirements. Without them, it would be nearly impossible to report services consistently or receive payment.
When it comes to digital health services, CPT codes for remote patient monitoring billing have created new opportunities for clinics to extend care outside the office. RPM billing for chronic conditions allows doctors to track a patient’s health data — such as blood pressure, glucose levels, or oxygen saturation — in real time using connected devices. These readings are securely transmitted, giving physicians actionable insights to intervene early and prevent complications.
It’s important to note that remote patient monitoring billing (RPM) is different from remote therapeutic monitoring (RTM). RPM codes (99453, 99454, 99457, 99458) are designed for tracking physiological data from FDA-approved medical devices, such as a heart monitor or digital blood pressure cuff. By contrast, RTM focuses on monitoring therapy-related data, such as musculoskeletal function or medication adherence, often without a connected device. For clinics, understanding this difference matters — using the wrong codes can lead to claim denials and compliance problems.
So, when should a clinic use CPT codes for remote patient monitoring? Typically, these codes are applied when:
- A patient has a chronic or acute condition that requires continuous monitoring.
- A doctor, nurse practitioner, or other qualified healthcare professional is reviewing transmitted data and providing care.
- The clinic provides patient education and device setup to ensure accurate usage.
- Ongoing monitoring and interactive communication occur each month.
These services are most commonly used for patients with conditions like hypertension, diabetes, heart failure, and COPD. In cities like Chicago, Los Angeles, and San Antonio, practices use RPM codes to not only improve patient outcomes but also secure Medicare reimbursement for RPM and support value-based care models.
By using CPT codes correctly, doctors can ensure patients receive reliable, continuous support while also protecting their clinic’s revenue. To learn more about how remote monitoring works in clinical practice, visit our detailed guide on Remote Patient Monitoring.
Breaking Down the Key RPM CPT Codes
Remote Patient Monitoring (RPM) relies on four key billing codes that allow doctors, clinics, and billing teams to track and get reimbursed for the different services provided. Each CPT code covers a distinct part of the workflow — from setup to ongoing monitoring. Understanding how and when to use them ensures accurate reimbursement and helps practices stay compliant with CMS and Medicare reimbursement for RPM billing compliance rules requirements.
CPT Code 99453: Initial Setup and Patient Education for Remote Monitoring
CPT 99453 is used when a clinic first introduces a patient to remote patient monitoring. It covers the time and resources spent on patient onboarding, device setup, and education. For example, if a physician or staff member helps a patient in New York City learn how to properly use a connected blood pressure monitor, this service can be billed under 99453.
This code is typically billed once per patient per episode of care. Physicians, nurse practitioners, and qualified healthcare professionals can bill for this service, but the key requirement is that the setup and training must be documented in the patient’s record. The documentation should note the device provided, the education given, and confirmation that the patient can use the device correctly.
Accurate use of 99453 ensures that practices are reimbursed for the time spent preparing patients for RPM billing for chronic conditions — a critical step in ensuring ongoing monitoring success.
CPT Code 99454 – Device Supply and Data Transmission
CPT 99454 covers the monthly supply of devices and the transmission of patient data. This code ensures that practices are compensated for providing patients with the technology required to share their health data securely.
Examples of eligible devices include:
- Digital blood pressure monitors
- Glucometers
- Pulse oximeters
- Weight scales
- FDA-approved wearable heart monitors
Each device must meet FDA standards for medical devices, and the data must be automatically transmitted — patient self-reported readings usually don’t qualify.
99454 is typically billed once per month per patient, regardless of how many devices are supplied. For practices in Los Angeles or Houston, this code is especially useful for scaling RPM programs across large patient populations with chronic conditions like diabetes or hypertension.
Accurate use of this code helps doctors recover the costs of device management while ensuring Medicare beneficiaries and other patients continue to receive ongoing monitoring support.
CPT Code 99457 – First 20 Minutes of Monitoring and Care
CPT 99457 is one of the most critical codes in remote patient monitoring billing because it reflects the actual clinical time providers spend reviewing data and interacting with patients. It covers the first 20 minutes of monitoring and care management services delivered within a calendar month.
To bill for 99457, the service must include interactive communication with the patient or caregiver. This means phone calls, secure video chats, or other live communication methods that allow providers to discuss the data and provide guidance. Simply reviewing transmitted data without direct patient interaction is not enough.
Medicare reimbursement for RPM services under 99457 has become a significant financial support for clinics in cities like Chicago and Dallas. It allows providers to be paid for their time while ensuring patients with conditions like COPD, heart disease, or diabetes receive active engagement each month.
To avoid compliance risks, clinics should document the exact time spent, the type of communication used, and the medical decisions or advice provided during these interactions.
CPT Code 99458 – Each Additional 20 Minutes
CPT 99458 is an add-on code that captures additional monitoring time beyond the initial 20 minutes covered under 99457. It allows clinics to bill for each extra 20-minute block of clinical staff or provider time spent on RPM services during a calendar month.
For example, if a physician in San Diego spends 40 minutes reviewing patient data and communicating with a patient, the clinic can bill both 99457 and 99458. If the time extends to 60 minutes, 99457 and two units of 99458 may be billed.
This code is particularly valuable for small practices and private clinics, which often spend more time supporting patients with multiple chronic conditions. By properly documenting and billing 99458, these practices can ensure fair compensation for the extended care they provide.
To reduce errors and improve reimbursement, many clinics turn to digital platforms like SmartCare360 to streamline tracking and billing. Accurate time documentation not only prevents claim denials but also strengthens the clinic’s overall Revenue Cycle Management process.
How to Bill Remote Patient Monitoring Services Correctly
Correctly billing for remote patient monitoring (RPM) is one of the most important steps for clinics and doctors in the United States. While the CPT codes for remote patient monitoring (99453, 99454, 99457, 99458) provide a clear structure, mistakes in compliance, documentation, or coding often lead to claim denials and lost revenue. For practices in cities like New York City, Philadelphia, or Phoenix, following the right billing workflow ensures both proper reimbursement and patient care continuity.
Below, we break down the key areas that clinics should pay attention to when billing for RPM billing compliance rules services.
Understanding RPM Billing Compliance Rules
When billing RPM, doctors and billing teams must follow both Medicare reimbursement for RPM billing compliance rules and CMS guidelines. These rules define which patients qualify, how services must be delivered, and what documentation is required for reimbursement. For example, Medicare typically requires that patients have one or more chronic conditions being actively managed through RPM billing compliance rules.
Another essential compliance factor is HIPAA. All transmitted patient data — from blood pressure readings to glucose levels — must be collected, stored, and shared using HIPAA-compliant platforms. Any gap in security could not only risk patient privacy but also cause compliance violations during audits.
For practices in cities like Los Angeles or San Antonio, maintaining compliance is more than a legal requirement — it’s also key to sustaining revenue. To learn more about CMS requirements and HIPAA compliance in billing, explore our detailed guide on Digital Health Billing & Compliance.
Documentation Requirements for RPM Billing
Even if services are provided correctly, missing or incomplete documentation can cause denied claims. Clinics need to maintain thorough records of each RPM activity. Common documentation gaps include:
- Failing to record the start and end times of monitoring sessions.
- Omitting the type of device used for patient monitoring.
- Not documenting patient consent for RPM billing for chronic conditions services.
- Lack of notes on interactive communication with the patient.
Acceptable logs may include:
- Device transmission reports (blood pressure logs, glucose reports, pulse oximeter readings).
- Notes from nurses or physicians reviewing the data.
- Documentation of patient education during setup.
- Audit-ready records of each billing code applied.
By building an organized documentation workflow, practices in Houston, Dallas, and San Diego can improve billing accuracy and reduce compliance risks. Strong documentation also ensures clinics are prepared for billing audits, which are increasingly common under CMS.
Common RPM Billing Mistakes and How to Avoid Them
Many practices lose reimbursement due to preventable mistakes. Some of the most frequent issues include:
- Incorrect code usage: Billing for 99457 without documenting interactive communication, or billing 99454 for non-FDA-approved devices.
- Failing to document device transmission: If patient data is not automatically transmitted, claims may be denied.
- Double billing: Submitting both RPM and RTM codes for the same service period.
- Inconsistent time tracking: Not recording the required 20 minutes before billing 99457.
For doctors in Chicago or Jacksonville, avoiding these mistakes can make the difference between steady reimbursement and repeated claim denials. Clinics should regularly train staff on updated billing rules and adopt digital tools that track time and patient engagement accurately.
To explore these issues in greater depth, including real-world examples of denied claims, see our full guide on Remote Patient Monitoring Billing.
RPM Billing for Chronic Conditions (Hypertension, Diabetes, COPD)
Remote Patient Monitoring (RPM) is especially powerful when applied to chronic diseases like hypertension, diabetes, and COPD. These conditions require consistent tracking, early intervention, and regular adjustments to treatment. By integrating RPM into routine care, clinics can improve patient outcomes while ensuring billing is aligned with Medicare and payer guidelines.
For hypertension, RPM allows providers to monitor blood pressure readings daily or weekly instead of waiting for sporadic clinic visits. This real-time data makes it easier to detect concerning patterns such as sudden spikes, which may require medication adjustments. CPT codes for remote patient monitoring 99453 and 99454 often cover the initial setup and monthly device supply for connected blood pressure monitors. For ongoing engagement, 99457 and 99458 ensure providers are reimbursed for time spent reviewing patient data and counseling.
In diabetes management, RPM supports continuous monitoring of glucose levels, especially with smart glucometers and continuous glucose monitors (CGMs). Providers can use these insights to guide insulin dosing, diet recommendations, and exercise planning. Proper billing requires documenting device transmissions and interactive patient communication each month. Medicare reimbursement for RPM and commercial insurers recognize these services as medically necessary, especially for patients with poorly controlled diabetes.
For patients with COPD, connected pulse oximeters and spirometry devices play a critical role. RPM enables earlier recognition of worsening symptoms, such as declining oxygen saturation, which can reduce hospital readmissions. Clinics can bill for monitoring time spent evaluating patient data, while ensuring compliance with CMS’s minimum interaction standards.
When billing RPM for chronic conditions, practices must carefully document medical necessity, device use, and patient engagement. Chronic conditions often qualify for long-term RPM services, making accuracy in coding essential for continuous reimbursement. In many cases, these services can be billed alongside Chronic Care Management (CCM), as long as documentation clearly distinguishes the time spent on each service.
By combining strong documentation with the right CPT codes, practices can create sustainable revenue streams while helping patients manage conditions that require lifelong monitoring.

RPM vs RTM Billing: Key Differences Doctors Should Know
Remote Patient Monitoring (RPM) and Remote Therapeutic Monitoring (RTM) are often discussed together, but their billing rules are not identical. Understanding the differences helps providers choose the correct codes and avoid denied claims.
RPM billing codes (99453, 99454, 99457, 99458) apply when clinicians track physiologic data—for example, blood pressure, glucose, or oxygen saturation. These codes require connected medical devices that automatically transmit data. RPM can be billed by physicians and certain clinical staff under general supervision, making it widely accessible for primary care and specialty practices.
By contrast, RTM billing codes (98975, 98976, 98977, 98980, 98981) are designed for non-physiologic data, such as therapy adherence, musculoskeletal progress, or medication intake. RTM often supports specialties like physical therapy, orthopedics, and behavioral health. Unlike RPM, RTM can be billed by non-physician providers, including physical therapists, but requires more manual patient input rather than automated device transmission.
When should a clinic use RPM over RTM? If a patient with hypertension is uploading daily blood pressure readings through a Bluetooth cuff, RPM codes apply. If a physical therapy patient is tracking exercise adherence in an app, RTM codes are more appropriate. Some clinics even use both models for different aspects of care, but claims must clearly separate physiologic monitoring from therapeutic tracking.
Choosing between RPM and RTM is not only about data type but also about who delivers the service and how the data is captured. By aligning codes correctly, providers ensure compliance while maximizing reimbursement opportunities.

Best RPM Billing Tools for Small Practices
For small and mid-sized clinics, accurate billing can make the difference between steady reimbursement and frequent claim denials. Remote Patient Monitoring (RPM) generates recurring claims each month, and without the right tools, billing teams may struggle to keep up. Software designed for RPM billing reduces errors, improves compliance, and ensures clinics capture every eligible dollar.
The best RPM billing tools handle automation of repetitive tasks, such as claim generation, code verification, and monthly device billing. Instead of manually tracking which patients qualify for CPT codes 99453 through 99458, software can flag eligible encounters automatically. This prevents underbilling while also protecting against coding errors that may trigger audits.
Another key feature is EHR integration. When RPM billing tools sync directly with electronic health records, clinical notes and device data flow seamlessly into claims. This reduces duplicate entry and ensures documentation supports reimbursement. Many platforms also offer real-time dashboards, making it easy for providers to confirm which patients meet the minimum time thresholds for codes like 99457 and 99458.
For smaller practices with lean staff, scalability and ease of use matter. A tool that combines scheduling, patient monitoring, and billing into a single platform reduces administrative burden while keeping compliance front and center. Reporting features also help clinics track reimbursement trends, so they can identify gaps before they impact revenue.
By choosing software that balances automation, compliance, and integration, small practices can bill confidently for RPM while focusing on patient care.
