What Is Remote Patient Monitoring (RPM)?

Remote Patient Monitoring (RPM) is a form of telehealth that uses technology to monitor patients' health outside of traditional clinical settings, such as in their homes. By tracking physiologic data like blood pressure, weight, blood glucose, and oxygen saturation, RPM empowers providers to make proactive decisions, improve care quality, and prevent complications.

RPM is particularly effective for managing chronic conditions such as:

• Hypertension
• Diabetes
• COPD
• Atrial fibrillation
• Heart failure

By providing continuous access to patient data, RPM fosters better communication, improves adherence to treatment plans, and enhances health outcomes.

Who Can Perform RPM Services?

According to the Centers for Medicare & Medicaid Services (CMS), RPM services can be performed by:

• Physicians
• Qualified Healthcare Professionals (QHPs)
• Auxiliary Personnel (clinical staff) under general supervision of the billing provider

A physician must document the clinical necessity of RPM in the patient’s medical record, and the services must meet CMS criteria for monitoring either an acute or chronic condition.

How Does Remote Patient Monitoring Work?

The 5 Steps to Set Up an RPM Program

1. Patient Opt-In
2. Patients must provide consent before starting RPM services. For Medicare patients, this opt-in can occur during a face-to-face visit or via telehealth (if the patient has had an in-person interaction with the provider in the last 12 months).
3. Order and Setup the RPM Device
   • The provider orders an FDA-cleared RPM device, such as a blood pressure monitor, glucometer, or pulse oximeter.
   • Devices may be shipped directly to the patient by a third-party provider, streamlining the setup process.
4. Patient Uses the Device
   • Patients are required to use their RPM device for at least 16 days in a 30-day billing period to meet Medicare’s requirements for reimbursement under certain CPT codes (99453, 99454).
   • Devices automatically transmit real-time data to the provider’s secure platform via cellular or Bluetooth technology.
5. Data Review and Intervention
   • Providers or their staff review the data, assess trends, and intervene when necessary. To bill for CPT code 99457, the provider must spend at least 20 minutes per month in active communication or care management with the patient.
6. Submit Claims for Reimbursement
   • Providers track and document RPM services, including device usage, data review, and patient communication, before submitting claims to Medicare.

Remote Patient Monitoring Billing Codes

Medicare incentivizes the use of RPM through a set of specific CPT codes designed to reimburse providers for everything from device setup to ongoing monitoring and treatment management.

Here’s a complete breakdown of the 2025 RPM CPT Codes and their requirements:

1. CPT 99453 – Device Setup and Patient Education

• Reimbursement: $19.73
• What It Covers: One-time payment for setting up the RPM device and educating the patient on how to use it.
• Key Requirement: The patient must use the device for at least 16 days in a 30-day period before billing.

2. CPT 99454 – Device Supply and Data Transmission

• Reimbursement: $43.03 (billed monthly)
• What It Covers: Monthly reimbursement for providing the RPM device, collecting data, and transmitting it securely to the provider.
• Key Requirement: The device must be used for at least 16 days in a 30-day billing period.

3. CPT 99457 – Initial 20 Minutes of Treatment Management

• Reimbursement: $47.88
• What It Covers: The first 20 minutes per month of care management, including interactive communication with the patient (e.g., via phone, text, or video).
• Key Requirement: Must involve direct communication with the patient.

4. CPT 99458 – Additional 20-Minute Increments of Treatment Management

• Reimbursement: $38.50 (per additional 20 minutes)
• What It Covers: For patients requiring more than 20 minutes of treatment management, this code reimburses additional time spent by providers or clinical staff.

5. CPT 99091 – Collection and Interpretation of Remote Data

• Reimbursement: $52.71
• What It Covers: Reimbursement for at least 30 minutes per month spent collecting, interpreting, and processing patient data. Interactive communication is not required for this code.

Billing and Compliance Requirements

To ensure your RPM program is reimbursed by Medicare, you must meet these CMS billing guidelines:

1. Use FDA-Cleared Devices
2. Only devices that meet the FDA’s definition of a medical device can be used for RPM.
3. Meet the 16-Day Rule
4. CPT codes 99453 and 99454 require the patient to use the device for at least 16 days per 30-day billing period.
5. Document Interactive Time
6. For CPT codes 99457 and 99458, at least part of the billable time must include interactive communication with the patient.
7. Track Time Accurately
8. All time spent on RPM activities must be carefully documented. CMS does not allow rounding up time (e.g., billing 35 minutes as 40).
9. Submit Detailed Records
10. Providers must submit detailed documentation, including the services performed, time spent, and patient usage data, when billing Medicare.
