Remote therapeutic monitoring (RTM) is a healthcare service that tracks non-physiological patient data tied to a treatment plan, such as pain levels, exercise adherence, and medication compliance. Unlike traditional remote monitoring that focuses on vital signs like heart rate and blood pressure, RTM captures how well a patient is responding to and following through with a prescribed therapy. It was introduced by Medicare in 2022 and is primarily used in musculoskeletal and respiratory care.
What RTM Actually Tracks
The easiest way to understand RTM is to think about what happens between your appointments. If you’re recovering from knee surgery, your physical therapist might see you twice a week, but the other five days matter just as much. RTM fills that gap by collecting data on what you’re doing at home: whether you completed your exercises, how much pain you experienced, how your range of motion is progressing, and how consistently you’re sticking to the plan.
This data is “non-physiologic,” meaning it doesn’t measure things like blood pressure or oxygen levels. Instead, it captures treatment-related information. For musculoskeletal conditions, that might mean a wearable sensor tracking your movement during prescribed exercises. For respiratory conditions like asthma or COPD, it could be an inhaler sensor logging whether you’re taking your medication on schedule and how you’re responding to it. The data flows to your care team through an internet-connected device or app, giving them a real-time picture of your recovery without requiring an office visit.
How RTM Differs From Remote Patient Monitoring
Remote patient monitoring (RPM) has been around longer and focuses on physiologic data: heart rate, blood pressure, blood glucose, body temperature. It’s typically billed by physicians and used in chronic disease management for conditions like hypertension or diabetes. RTM was specifically created so that practitioners who couldn’t bill RPM codes, particularly therapists, could offer a similar type of monitoring service for therapy-related care.
The key distinction is the type of data. RPM collects numbers your body produces automatically. RTM collects information about how you’re engaging with your treatment. Pain tolerance, medication adherence, exercise completion, and functional progress all fall under RTM. This makes RTM especially well-suited for rehabilitation and respiratory therapy, where the patient’s active participation between visits is a major factor in outcomes.
Who Provides RTM Services
RTM opened the door for a wider range of clinicians to bill for remote monitoring. Physical therapists, occupational therapists, and speech-language pathologists can all provide and bill for RTM services, as long as they do so under a therapy plan of care. Physicians, physician assistants, nurse practitioners, and clinical nurse specialists can also bill for RTM.
Physical therapist assistants and occupational therapy assistants can participate in delivering RTM, but they must work under the general supervision of a licensed physical therapist or occupational therapist, respectively. This structure keeps the licensed clinician responsible for interpreting the data and adjusting the treatment plan based on what the monitoring reveals.
What the Monitoring Looks Like in Practice
A typical RTM setup involves a patient using a sensor, app, or connected device at home that collects and transmits data to their care team. Here’s how it plays out across common scenarios:
- Chronic low back pain: A patient wears a sensor paired with an app that tracks their movement during prescribed exercises. The care team reviews the data to see if the patient is performing exercises correctly and consistently, and adjusts the plan based on reported pain levels.
- Post-surgical knee or shoulder rehab: After a meniscus repair or rotator cuff surgery, a patient logs daily sensor-based rehab sessions. Their therapist can spot drops in adherence or unexpected pain patterns before the next in-person visit.
- COPD or asthma management: An inhaler sensor tracks medication use over weeks. If a patient’s adherence drops or their symptom reports worsen, the care team can intervene early rather than waiting for the condition to deteriorate.
The care team’s side involves reviewing the incoming data, updating the treatment plan when needed, and connecting with the patient. At least one real-time interaction with the patient or their caregiver is required each month, whether by phone or video. A clinician managing an ACL-repair patient, for example, might spend 7 minutes reviewing data, 5 minutes adjusting the plan, and 4 minutes on a live call, all of which counts toward billable treatment management time.
Does RTM Improve Outcomes?
A retrospective study comparing in-person physical therapy alone to in-person PT combined with RTM found measurable differences in both adherence and functional recovery. Among 306 patients who received PT with RTM and 918 who received PT alone, 72% of the RTM group hit their functional recovery benchmark at discharge, compared to 63% of the control group. RTM patients were also significantly more likely to attend more than two visits per week (36% vs. 24%).
After controlling for other variables, RTM participation made patients about 1.5 times more likely to reach their functional goals at discharge. The pattern suggests that the accountability and real-time feedback loop of monitoring helps keep patients engaged with their rehab programs, which is one of the biggest challenges in physical therapy. Patients who do their exercises consistently recover faster, and RTM gives both the patient and therapist visibility into whether that’s actually happening.
How Billing and Reimbursement Work
Medicare reimburses RTM through a set of billing codes that cover two categories: device supply (getting the monitoring technology to the patient) and treatment management (the clinician’s time reviewing data and communicating with the patient).
For device supply, codes are split by body system and by how many days data was collected. Musculoskeletal and respiratory monitoring each have their own codes, with one tier covering 2 to 15 days of data transmission in a 30-day period and another covering 16 to 30 days. The higher-tier codes require at least 16 days of data collection within the month.
Treatment management codes cover the clinician’s time spent reviewing data, adjusting care plans, and communicating with the patient. The first billable increment starts at 10 minutes of clinician time in a calendar month, with additional time billed in further increments. These services are paid under the Physician Fee Schedule in most settings. When therapists provide RTM, they must always do so under a documented therapy plan of care and include specific modifiers on their claims.
Private insurers vary in their RTM coverage. Medicare’s adoption of these codes in 2022 set the framework, but coverage from commercial plans is still expanding. If you’re considering RTM as part of your care, it’s worth checking whether your specific plan covers it.
Devices Used in RTM
RTM devices range from wearable motion sensors to smart inhaler attachments to app-based platforms where patients log symptoms and exercise completion. The devices must meet the FDA’s definition of a medical device, meaning they’re intended for use in diagnosing, treating, or monitoring a condition and are regulated accordingly. This distinguishes RTM tools from general consumer fitness trackers, which aren’t designed or cleared for clinical use.
In practice, many RTM platforms combine a physical sensor with a smartphone app. The sensor captures objective data (like whether your shoulder reached a certain range of motion during an exercise), while the app may prompt you to report subjective information like pain levels or how you felt during the session. Together, this gives your care team a more complete picture than either type of data alone.
