Over the last few years, remote patient monitoring (RPM), also referred to as remote physiologic monitoring, became one of the more lucrative Medicare care management programs. Using average 2023 RPM reimbursement rates, if 100 patients are enrolled in an RPM program and each receives the minimum care management services each month, that will generate annual reimbursement exceeding $115,000. We can largely thank the overhaul of RPM CPT codes in 2020 for such generous reimbursement. 

One of the most important steps organizations must complete to capture this reimbursement, after appropriately identifying and enrolling eligible patients in an RPM program, is proper coding of their remote patient monitoring services. This Prevounce Quick Guide outlines the current remote patient monitoring CPT codes and shares some tips for proper RPM coding. We've also included the 2023 average Medicare reimbursement rates for the codes discussed in the guide. 

Remote Patient Monitoring CPT Codes and 2023 RPM Reimbursement Rates 

As of January 2023, there are essentially four key CPT codes that cover remote patient monitoring: 99453, 99454, 99457, and 99458. Their descriptions and 2023 reimbursement rates are as follows: 

CPT 99453 

Remote monitoring of physiologic parameter(s) (eg, weight, blood pressure, pulse oximetry, respiratory flow rate), initial; set-up and patient education on use of equipment.  

  • 2023 reimbursement rate: $18.84 

CPT 99454 

Remote monitoring of physiologic parameter(s) (eg, weight, blood pressure, pulse oximetry, respiratory flow rate), initial; device(s) supply with daily recording(s) or programmed alert(s) transmission, each 30 days 

  • 2023 reimbursement rate: $48.93 

CPT 99457 

Remote physiologic monitoring treatment management services, clinical staff/physician/ other qualified health care professional time in a calendar month requiring interactive communication with the patient/caregiver during the month; initial 20 minutes 

  • 2023 reimbursement rate: $47.60 

CPT 99458 

Remote physiologic monitoring treatment management services, clinical staff/physician/ other qualified health care professional time in a calendar month requiring interactive communication with the patient/caregiver during the month; additional 20 minutes 

  • 2023 reimbursement rate: $38.68 

Remote Patient Monitoring CPT Codes: 4 Tips 

Here are four tips to help ensure you use these RPM codes properly: 

  • A provider can only bill 99454 once per patient every 30 days regardless of the number of devices used. 
  • Under 99457, remote physiologic monitoring can be performed by the billing physician, qualified healthcare professional (QHCP), or clinical staff. It requires at least 20 minutes of logged management time each month. 
  • Once 99457 has been billed, a practice can add up to two instances of 99458 per month: once at 40 minutes and once at 60 minutes. 
  • A provider can bill via these RPM codes during the same service period as chronic care management (CCM) (via CPT codes 99487-99490), transitional care management (TCM) (via CPT codes 99495-99496), and behavioral health integration (BHI) (via CPT codes 99484, 99492-99494). Combining RPM with CCM as part of a broader comprehensive care management program can lead to an even more beneficial program for patients and organizations, which is discussed in this Medical Economics column by Prevounce CEO Daniel Tashnek, JD.   

What to Know About CPT 99091 

CPT 99091 was created in the early 2000s to code for remote patient monitoring. Its descriptor: "Collection and interpretation of physiologic data (eg, ECG, blood pressure, glucose monitoring) digitally stored and/or transmitted by the patient and/or caregiver to the physician or other qualified health care professional, qualified by education, training, licensure/regulation (when applicable) requiring a minimum of 30 minutes of time, each 30 days." 
For a period after the newer codes discussed above were introduced, it was not advisable to bill using CPT 99091 because of limitations and requirements. However, that changed with the 2021 Medicare physician fee schedule final rule that permitted providers to begin billing CPT 99091 with newer codes. Federal rules now allow providers to bill for "complex" RPM management when they are required to spend substantial time managing the patient and their remote patient monitoring care plan.  

Furthermore, CMS stated that CPT 99091 can be billed each 30 days whenever such complex provider management occurs and without affecting a provider's ability to bill clinical staff time via CPT 99457 each month.

Growing Use of Wearables and Their Role in Remote Patient Monitoring

Over the past decade, there has been a huge surge in the availability and popularity of wearable technology. This has largely been driven by the Apple Watch, with credit to the Fitbit, and we are seeing newer technologies over the past few years empowering patients to take more control over their health.
