The owner of a four-therapist outpatient physical therapy clinic sat through a vendor demo for a remote patient monitoring platform. The pitch was persuasive: home exercise tracking, monthly revenue per patient, almost no setup. Then her biller asked the question nobody in the demo had raised. Physical therapists can’t bill RPM codes at all. What the clinic could bill, and what actually fit its patients, was remote therapeutic monitoring.
RPM and RTM share three letters and a lot of marketing copy. Underneath, they monitor different kinds of data, accept data captured in different ways, and are billed by different licenses under different rules. If you pick the wrong one, you either build a program you can’t bill or one that doesn’t fit the patients you actually treat.
This guide walks through RPM vs RTM side by side: what each program covers, how RTM works inside a physical therapy practice, a three-question test for choosing between them, the mistakes we see most often, and what the 2027 proposals would change. It comes from the remote monitoring programs Care VMA supports in independent practices and therapy clinics.
“Your Clinic Should Be Doing RPM”
The PT clinic in that demo, in suburban Phoenix, nearly signed a 24-month platform contract built around RPM codes. When we reviewed its patient mix with the owner, almost every candidate was a post-surgical knee or shoulder patient whose progress showed up in range of motion, pain scores, and whether the home exercise program actually got done. None of that is physiologic data in the RPM sense. All of it fits RTM’s musculoskeletal codes.
The clinic launched RTM instead, starting with total knee replacement patients under active plans of care. The therapists already knew which patients were skipping home exercises. Now they could see it within days, not at the next visit.
The vendor’s platform worked fine. It was built for a program the clinic had no license to bill.
RPM vs RTM: What Each Program Monitors and Who Bills It
What Remote Patient Monitoring Covers
Remote patient monitoring (RPM) tracks physiologic data: blood pressure, weight, blood glucose, oxygen saturation, heart rate. The data comes from a device that meets the FDA definition of a medical device and transmits readings automatically. RPM requires an established patient relationship and patient consent, and it’s billed by physicians and nonphysician practitioners who can bill evaluation and management services, with clinical staff working under general supervision. It’s the program for hypertension, heart failure, diabetes, and other conditions with a measurable physiologic signal.
What Remote Therapeutic Monitoring Covers
Remote therapeutic monitoring (RTM) tracks non-physiologic data about how a patient is responding to treatment: musculoskeletal status, respiratory status, therapy adherence, medication adherence, and (under a separate code set) cognitive behavioral therapy. The device must still meet the FDA’s medical device definition, and software can qualify, but RTM data can be entered by the patient rather than captured automatically. Physical therapists, occupational therapists, speech-language pathologists, physicians, and nonphysician practitioners can bill RTM within their scope.
RPM vs RTM Side by Side
| RPM | RTM | |
|---|---|---|
| What’s monitored | Physiologic data (blood pressure, weight, glucose, oxygen saturation) | Therapeutic data (musculoskeletal or respiratory status, therapy or medication adherence and response, CBT) |
| How data is captured | Automatically transmitted by the device | Device-generated or patient self-reported |
| Device requirement | FDA-defined medical device | FDA-defined medical device (software can qualify) |
| Who can bill | Physicians and NPPs who can bill E/M | PTs, OTs, SLPs, physicians, NPPs within scope |
| Patient relationship | Established patient required | No established patient requirement today (proposed for 2027) |
| Setup code | 99453 | 98975 |
| Device supply codes | 99454 (16-30 days), 99445 (2-15 days) | 98976, 98977, 98978 (16-30 days); 98984, 98985, 98986 (2-15 days) |
| Management codes | 99470 (10-19 minutes), 99457 (20 minutes), 99458 (each additional 20) | 98979 (10-19 minutes), 98980 (20 minutes), 98981 (each additional 20) |
| Same patient, same period | Can’t be billed with RTM | Can’t be billed with RPM |
| Typical patients | Hypertension, heart failure, diabetes, COPD with oxygen monitoring | Post-surgical orthopedic, chronic musculoskeletal pain, COPD or asthma adherence, behavioral health |
Why the Names Mislead Practices
Both programs monitor patients, and both support therapy, so the words “patient” and “therapeutic” tell you very little. What separates them is the type of data, how it’s allowed to arrive, and whose license is on the claim.
Vendors blur it further. Many platforms support both programs, so a demo built for a primary care practice gets shown, unchanged, to a PT clinic. Some marketing still describes RTM as the program that “doesn’t need a medical device,” which skips over the FDA definition requirement and leaves practices exposed when a payer asks what the device is.
And the codes look alike. A biller who learned RPM can see 98977 and 99454 as the same idea with different numbers. They have different descriptors, different billers, and in a therapy practice, a different set of claim rules altogether.
Remote Therapeutic Monitoring Explained for Physical Therapy Practices
RTM Lives Inside the Plan of Care
When a physical therapist furnishes RTM, it becomes part of the therapy episode. The monitoring needs a reason in the plan of care (tracking range of motion after a total knee replacement, say, or home exercise adherence for chronic low back pain), and the claims follow therapy billing conventions, including the therapy modifier. The 2026 RTM codes sit on Medicare’s “sometimes therapy” list: billed by a physician outside a therapy plan of care, they aren’t therapy services; billed by a therapist, they are.
Our experience with PT clinics is consistent on one point. The plan of care language is where RTM programs succeed or fail an audit. A note that says “RTM initiated” says nothing. A note that names the measure, the reason, and what the therapist will do when the data changes holds up.
Supervision and the PTA’s Role
Physical therapist assistants in private practice can furnish RTM services under general supervision, so the supervising PT doesn’t have to be in the room or the building. That makes RTM workable for clinics where PTAs carry much of the follow-up load. The PTA payment adjustment applies to some RTM codes and not to the device supply codes, so the claim needs the right modifier on the right line.
Where RTM Meets Your Existing Therapy Billing
RTM charges billed under a therapy plan of care sit alongside your timed treatment codes, the therapy modifiers, and the annual therapy threshold. Confirm with your MAC how your RTM charges interact with the KX threshold for each patient, and build that check into the same workflow your team already uses. Our guide to physical therapy billing covers the 8-minute rule and the KX modifier in detail.
Signal, Source, Steward: Choosing RPM or RTM
Three questions decide which program fits a patient. Ask them in order.
Signal: What Are You Measuring?
If the clinical question is about a physiologic value (blood pressure, weight, glucose, oxygen saturation), the signal points to RPM. If it’s about how the patient is responding to treatment (range of motion, pain and function, adherence to exercises, an inhaler, or a medication), it points to RTM.
Source: How Does the Data Get to You?
RPM needs data the device transmits automatically. RTM accepts patient-reported data through a qualifying device or software. A patient logging pain scores and completed exercises in an app fits RTM. A cellular blood pressure cuff sending readings on its own fits RPM.
Steward: Who Is Licensed to Bill and Manage It?
A physical therapy practice can bill RTM and can’t bill RPM. A physician practice can bill either, so the choice comes down to signal and source. Pick the program your licenses support, then make sure someone on the team clearly owns the monthly management time.
When a Patient Fits Both
Some patients have both a physiologic and a therapeutic question. A COPD patient might need oxygen saturation tracking and inhaler adherence. A post-surgical patient might have high blood pressure. The two programs can’t be billed for the same patient in the same period, so the practice has to choose the program that answers the more pressing clinical question.
An orthopedic group we worked with had enrolled about 30 post-surgical patients in RTM while their primary care physicians billed RPM for the same patients’ blood pressure. Neither practice knew. Adding a check for other monitoring programs at enrollment (asking the patient, then confirming with the primary care office) caught the overlap before more claims went out. Our complete RPM billing guide covers the RPM side of that conversation.
Mistakes Practices Make With RPM and RTM
Buying a Platform Before Choosing a Program
Start with the patients and the licenses, then choose the platform. A platform chosen first tends to choose the program for you.
Assuming RTM Needs No Medical Device
RTM allows self-reported data, but the device still has to meet the FDA definition of a medical device. Ask the vendor how its software qualifies, and keep the answer on file.
Counting Days and Minutes Loosely
Device supply codes depend on days of data in a 30-day period, and management codes depend on minutes in a calendar month, with at least one real-time interactive communication. Estimates don’t survive an audit. Logs do.
Missing the Other Program
A patient on RPM with another practice can’t be on RTM with yours for the same period. Ask at enrollment, every time.
Leaving RTM Out of the Plan of Care
For therapists, RTM without a documented reason in the plan of care is a claim waiting to be denied.
What Separates RTM Programs That Pay Off
Adherence Is the Revenue Engine
The device supply codes pay only when patients actually send data, and the 2026 codes for 2-15 days help, but they don’t replace engagement. Programs that stall almost always share one feature: nobody owns the patients who go quiet.
A four-physician pulmonology practice we support launched RTM for COPD inhaler adherence and saw roughly half its enrolled patients fall below the data thresholds by the second month. The fix was administrative. A daily list of patients with no entries in three days, a reminder call the same afternoon, and a weekly reconciliation of data days and management minutes before claims went out. For that reconciliation, a medical billing virtual assistant matched each patient’s logged days and minutes against the code thresholds, so the clinical staff weren’t counting by hand at month end.
What the 2027 Proposals Would Change
CMS has proposed RTM and RPM changes for 2027. They’re proposals until the final rule is published, expected in early November 2026:
- Requiring RPM and RTM to be furnished only by clinical staff who are direct employees of the billing practitioner or practice.
- Requiring a face-to-face initiating visit before monitoring starts.
- Extending the established patient requirement to RTM.
- Reducing some payments, and possibly replacing the RPM and RTM CPT codes with a smaller set of G-codes.
If finalized, these would change how both programs are staffed and started, and practices relying on outside monitoring companies would need to review those arrangements. For how the monitoring rules differ from telehealth rules, see our comparison of remote patient monitoring vs telehealth.
Pick the Program That Matches the Data and the License
RPM and RTM answer different clinical questions for different licenses. RPM monitors physiologic data transmitted automatically and is billed by physicians and NPPs. RTM monitors how patients respond to treatment, accepts self-reported data, and is the remote monitoring program physical therapists, occupational therapists, and speech-language pathologists can bill. Run the Signal, Source, Steward test for each patient group, check for other programs at enrollment, and give adherence a clear owner.
There’s an honest limit here. Both programs are in the middle of regulatory change, and the 2027 proposals could reshape who furnishes the work and how it’s paid. Your licensed clinicians carry the clinical and compliance responsibility, so confirm your MAC’s guidance and the final rule before you scale either program.
The part that usually breaks is the daily administrative work: enrolling patients, getting devices and apps working, calling patients who stop sending data, and keeping days and minutes documented for the clinical team. Care VMA’s remote patient monitoring support is built around that coordination work, so your clinicians spend their monitoring time on the data and the decisions.
If you’re deciding between RPM and RTM, or running one and wondering why it underperforms, book a free consultation with the Care VMA team. We’ll run the Signal, Source, Steward test on your patient mix and show you where the workflow needs an owner.
Frequently Asked Questions
What is the difference between RPM and RTM?
RPM monitors physiologic data, such as blood pressure, weight, or glucose, from a device that transmits automatically. RTM monitors non-physiologic data about how a patient is responding to treatment, such as musculoskeletal or respiratory status and therapy or medication adherence, and it allows self-reported data.
Can physical therapists bill RPM?
No. RPM codes are billed by physicians and nonphysician practitioners who can bill evaluation and management services. Physical therapists can bill RTM, which covers musculoskeletal and respiratory status and therapy adherence, within their scope and under the therapy plan of care.
Can a patient be on RPM and RTM at the same time?
A patient can’t have both RPM and RTM billed for the same period. Practices should ask at enrollment whether the patient is already in another monitoring program and choose the program that answers the more pressing clinical question.
Does RTM allow self-reported data?
Yes. RTM data can be entered by the patient or generated by a device, but the device or software must still meet the FDA definition of a medical device. RPM requires data that the device transmits automatically.
What changes are proposed for RTM in 2027?
CMS has proposed requiring RTM and RPM to be furnished only by clinical staff who are direct employees of the billing practice, requiring a face-to-face initiating visit, extending the established patient requirement to RTM, and reducing some payments. These are proposals until the final rule is published.
Which RTM codes are new for 2026?
The 2026 additions include device supply codes for 2-15 days of data (98984 for respiratory, 98985 for musculoskeletal, and 98986 for CBT) and 98979 for 10-19 minutes of monthly treatment management. They sit alongside the existing 16-30 day device codes and the 20-minute management codes.
