RPM vs RTM for PT Providers: Key Differences

According to the CMS CY 2026 Medicare Physician Fee Schedule Final Rule (effective January 1, 2026), CMS has consistently held that RPM codes fall outside the Medicare benefit for qualified healthcare practitioners like physical therapists, occupational therapists, and speech-language pathologists, meaning a PT who bills RPM codes is submitting a false claim, regardless of the clinical value of the monitoring performed. That single eligibility rule resolves a confusion that costs practices real revenue and compliance risk every year.

The clinical foundation behind this rule is what actually matters day to day: remote therapeutic monitoring physical therapy programs are built around tracking exercise adherence, pain response, and functional status between visits – non-physiological data that RPM was never designed to capture. Understanding exactly where RPM ends and RTM begins shapes not just billing eligibility, but how a practice should structure its entire remote monitoring workflow.

What Is the Core Difference Between RPM and RTM?

The distinction CMS draws is about the type of data being monitored, not the technology used to collect it.

RPM: Physiological Monitoring

Remote Physiologic Monitoring (RPM) tracks physiological metrics and requires automatic data upload from a connected medical device. Common RPM data points include:

• Blood pressure
• Body weight
• Blood glucose levels
• Pulse oximetry (oxygen saturation)

RTM: Therapeutic Monitoring

Remote Therapeutic Monitoring (RTM) tracks non-physiological data tied to a course of treatment, and critically, it permits patient self-reported data through software-as-a-medical-device tools, not just automatic device uploads. RTM-eligible data includes:

• Musculoskeletal system status
• Respiratory system status
• Therapy or exercise adherence
• Pain levels and therapeutic response

This self-reporting allowance is what makes RTM practical for physical therapy. A patient logging completed exercises or reporting a pain score through an app satisfies RTM data requirements – something RPM's automatic-upload rule doesn't accommodate.

Difference Between RPM and RTM: Provider Eligibility

This is the distinction with the most direct compliance consequence.

Who Can Bill RPM

RPM is fundamentally a physician-driven program: CMS requires that RPM services be ordered, supervised, or furnished by a physician, nurse practitioner, or physician assistant. Clinical staff can perform RPM management time, but only under the general supervision of a physician, who carries the billing responsibility.

Who Can Bill RTM

RTM, by contrast, explicitly extends billing eligibility to physical therapists, occupational therapists, and speech-language pathologists as qualified healthcare professionals in their own right. This is the single most important reason PT practices use RTM rather than RPM: it's the pathway CMS actually built for therapy-driven remote care.

RPM vs RTM: CPT Codes and 2026 Billing Thresholds

The CY 2026 Physician Fee Schedule Final Rule introduced parallel new codes to both programs, lowering time and data thresholds that previously excluded shorter-engagement patients from billing eligibility.

When Should a PT Practice Use RTM Instead of RPM?

The answer for most physical therapy practices is straightforward: use RTM whenever the primary clinical need is monitoring therapy adherence, exercise compliance, functional outcomes, or therapeutic response, particularly for musculoskeletal conditions, which represent the largest RTM-eligible patient population in outpatient PT.

RPM simply isn't billable by physical therapists under current CMS rules, regardless of clinical appropriateness. A PT monitoring a patient's home exercise completion and self-reported pain levels between visits is squarely in RTM territory, both clinically and from a billing-eligibility standpoint.

How to Set Up an RTM Monitoring Workflow in a Physical Therapy Practice

Step 1: Confirm the Patient's Monitoring Data Qualifies as RTM, Not RPM

Exercise adherence, pain scores, and functional status reports are RTM data. Vital signs are RPM data and aren't billable by a PT regardless of platform.

Step 2: Select a Software-as-a-Medical-Device Platform That Supports Patient Self-Reporting

RTM's defining advantage over RPM is that patients can self-report through software tools rather than requiring automatic device uploads. A platform built around exercise delivery and adherence logging, rather than a wearable sensor, fits this requirement naturally for a PT caseload.

Step 3: Document the Minimum Data Collection Period Required for the Applicable Code

As of the 2026 rule, RTM can now be billed with as few as two days of device or patient-reported data within a 30-day period under newer codes, alongside the existing 16-day threshold for established codes.

Step 4: Track and Document Monthly Treatment Management Time

The new CPT 98979 code reimburses 10–19 minutes of monthly management including at least one interactive communication with the patient; the existing CPT 98980 covers 20 or more minutes. Only one can be billed per patient per month.

Step 5: Verify Your Locality's Reimbursement Rate

Use the CMS Physician Fee Schedule Look-Up Tool to confirm rates for your specific locality. Rates vary geographically, and national averages cited in industry guides are approximations.

Step 6: Audit for Mutual Exclusivity Before Submitting Claims

RTM and RPM cannot be billed for the same patient in the same calendar month under any combination of codes.

Each of these steps depends on having a reliable way to capture exercise adherence and patient-reported outcomes consistently, which is the clinical backbone of RTM, separate from the billing mechanics layered on top of it.

RTM Is Strategic Infrastructure, Not Just a Billing Code

The RPM vs RTM distinction is the foundation of whether a PT practice's remote care billing holds up under audit, and whether the practice can capture revenue for monitoring work that, in many clinics, is already happening informally and going unbilled. RTM was built specifically for the kind of non-physiological, therapy-adherence data physical therapists generate every day. Practices that build a deliberate RTM workflow, rather than treating it as an afterthought to existing telehealth services, convert care that's already clinically valuable into a properly documented, reimbursable revenue stream.

Frequently Asked Questions

How can I tell if my physical therapy practice should bill RTM or RPM for a specific patient?

Look at the type of data being monitored, not the technology. If you're tracking exercise adherence, pain response, or functional status, that's RTM data, and RPM isn't billable by a PT regardless. RPM is reserved for physiological metrics like blood pressure or glucose and requires physician-level billing eligibility that physical therapists don't have under current CMS rules.

What's the difference between RPM and RTM in terms of who can supervise the billing?

RPM requires physician, NP, or PA ordering and supervision, even when clinical staff perform the monitoring work. RTM allows physical therapists, occupational therapists, and speech-language pathologists to bill independently as qualified healthcare professionals, without requiring physician supervision for the billing itself. This is the main reason RTM, not RPM, is the correct pathway for PT-driven remote care.

Can a physical therapy practice bill both RPM and RTM for the same patient?

No. CMS rules explicitly prohibit billing RPM and RTM together for the same patient in the same calendar month, regardless of which specific codes within each family are used. If multiple providers attempt to bill for the same patient in the same period, only the first claim submitted is reimbursed and subsequent claims are denied.

What changed with RTM billing thresholds in the 2026 CMS Final Rule?

The 2026 rule introduced lower-threshold codes on both sides: CPT 98979 now reimburses 10 to 19 minutes of monthly RTM treatment management, compared to the previous 20-minute minimum under CPT 98980. New short-period device supply codes also allow billing with as few as two days of data transmission within a 30-day period, rather than requiring the previous 16-day minimum.

Does RTM require a specific medical device, or can patients self-report data through an app?

RTM explicitly permits patient self-reported data through software-as-a-medical-device tools, which is a key structural difference from RPM's requirement for automatic device uploads. This makes RTM considerably more practical for physical therapy, where exercise completion and pain levels are naturally self-reported by patients rather than captured by a wearable sensor.
