Remote physiologic monitoring (RPM) and remote therapeutic monitoring (RTM) answer different care questions. Choosing between them starts with the information the treating team needs—not with which code looks more attractive. FairPath helps practices organize enrollment, device context, review work, and time and communication records for the program the practice chooses.
Short answer: RPM monitors physiologic measurements such as blood pressure, oxygen saturation or weight. RTM monitors treatment adherence and response and may include patient-reported information transmitted through a qualifying connected medical device. Medicare does not permit concurrent RPM and RTM billing for the same patient. Choose the family that fits the clinical question, data pathway and service your team will furnish.
Key Takeaways
- RPM measures physiology; RTM monitors adherence and response to a therapeutic treatment.
- A portal, exercise video library or wellness app is not automatically a qualifying monitoring device.
- RPM requires an established patient relationship under Medicare; RTM does not have that same requirement.
- The 2026 device codes use 30-day periods, while management uses calendar months and requires live interactive communication.
- 98979 is RTM's first-10-minute treatment-management code, not a device-supply category.
- Appropriate supervised clinical staff and therapy-assistant pathways exist; neither family makes administrative minutes automatically reportable.
- FairPath organizes evidence and human review; the practice owns the clinical workforce, program selection and claims.
What each program measures
RPM uses electronically collected physiologic information that automatically uploads to a secure location for practitioner analysis. Common examples are blood pressure, oxygen saturation, blood glucose and weight. The connected device supplies a measurement; the team interprets it in the patient's care context.
RTM captures nonphysiologic information related to a therapeutic treatment. The information may include patient-reported adherence and response transmitted through a connected medical device. Respiratory, musculoskeletal and cognitive behavioral therapy (CBT) device-supply categories appear in the code structure. A patient reporting how treatment is going is not the same thing as a physiologic sensor reporting a measurement.
| Question | RPM | RTM |
|---|---|---|
| What information is central? | Physiologic measurements | Treatment adherence and response |
| Typical clinical question | What is happening to blood pressure, weight or oxygen saturation between visits? | How is the patient following and responding to the treatment plan? |
| Data pathway | Electronic collection and automatic secure upload | Connected medical-device pathway; information may be patient-reported |
| Established patient requirement | Yes under Medicare | Not the same Medicare requirement |
| Clinical response | Interpret the measurement and decide appropriate care | Interpret treatment progress and decide appropriate care |
The distinction is not “medical practice versus therapy practice.” A physician may operate an appropriate RTM service, and eligible therapists have an RTM pathway. Nor is it “hardware versus software.” The relevant questions are the intended use, qualifying medical-device framework, data being collected and service furnished.
Match the clinical question to the right device
Start by writing the decision the treating team expects to make. “Collect more data” is too vague. “Review home blood-pressure trends before deciding whether the care plan needs adjustment” describes a physiologic question. “Understand whether the patient is completing the prescribed exercise plan and how symptoms and function are responding” describes a therapeutic question.
Then evaluate the exact product. Request its intended-use and device information, demonstrate the data pathway and test whether the team can identify the patient, date, relevant information and review history. For RPM, patient typing into a portal cannot substitute for the required automatic physiologic upload. For RTM, merely assigning exercises or sending reminders does not demonstrate a qualifying therapeutic monitoring service.
The CMS remote-monitoring booklet describes the qualifying medical-device and data requirements. Device qualification is different from clinical appropriateness: equipment may support a service while still being unsuitable for a particular patient's dexterity, connectivity, understanding or treatment goal.
Data quality also affects clinical interpretation. A cuff used incorrectly may produce misleading readings. Patient-reported therapeutic information may be incomplete or need clarification. A missing data day can indicate a technical problem, treatment burden or a change in the patient's condition. The team needs a support and follow-up process, not just a transmission counter.
The 2026 code map: two periods, separate evidence
The CY 2026 structure adds shorter device-data and first-10-minute management alternatives. CMS says the shorter and longer device codes are not additive; the 10- and 20-minute management bases are also alternatives. These are summarized code structures, not a substitute for the licensed CPT guidance governing an actual claim.
| Service | RPM | RTM |
|---|---|---|
| Setup and education | 99453; two days of monitoring in a 30-day period | 98975; two days of monitoring in a 30-day period |
| Device supply: 2–15 days per 30 days | 99445 | Respiratory 98984; musculoskeletal 98985; CBT 98986 |
| Device supply: 16–30 days per 30 days | 99454 | Respiratory 98976; musculoskeletal 98977; CBT 98978 |
| First 10 management minutes per calendar month | 99470 | 98979 |
| First 20 management minutes per calendar month | 99457 | 98980 |
| Each additional 20 minutes after the 20-minute base | 99458 | 98981 |
Do not mix the clocks
CY 2026 Medicare: use the requirements for the applicable code family.
Device data · 30 days
Choose the applicable 2–15-day or 16–30-day alternative.
Management · calendar month
Choose the applicable initial 10- or 20-minute base. Additional 20-minute units follow the 20-minute base.
Live interactive communication with the patient or caregiver is part of the treatment-management requirement. CMS explains that it contributes to the cumulative time but need not account for all of it. The record should show the communication, clinical work, who performed it and the nonduplicated time. The existence of an automated message or a dashboard login is not sufficient evidence of the required live interaction.
Management is not dependent on reaching 16 device-data days. Suppose an appropriate service has 12 qualifying data days and 23 qualifying management minutes including the required live communication. The device side belongs in the shorter-duration category, while the management side is assessed against its own 20-minute base requirements. Twenty-three minutes is not a 20-minute base plus an additional 20-minute unit, and the 10-minute base is not added to the 20-minute base.
Thresholds determine how a furnished service fits the code structure; they should not determine how much care a patient receives. A patient needing more support should receive clinically appropriate care even when the additional work does not meet a separate add-on threshold. Medicare Advantage and other payers may apply different coverage or authorization policies, so use the patient's payer and actual fee schedule for financial planning.
Who can furnish the work and who remains accountable?
For services billed by a physician or nonphysician practitioner (NPP), appropriate clinical staff may furnish remote-monitoring work under the billing practitioner's general supervision through the applicable incident-to arrangement. CMS finalized general supervision for RTM services beginning in 2023. The practice must still meet licensure, scope, supervision and service requirements; assigning a task to an employee does not make it clinical management.
Eligible physical therapists (PTs) and occupational therapists (OTs) may furnish RTM under the relevant therapy plan of care. Since 2024, private-practice PTs and OTs may use general supervision for physical therapist assistants (PTAs) and occupational therapy assistants (OTAs) furnishing RTM.
For these therapy services, GP identifies the physical-therapy plan of care and GO the occupational-therapy plan of care. When assistant involvement meets CMS's applicable threshold, CQ identifies PTA work and CO identifies OTA work. The 2026 final rule applies the assistant-modifier policy to the new management code 98979, but excludes respiratory and musculoskeletal device codes 98976, 98977, 98984 and 98985. These two sets of modifiers answer different questions: what therapy service is being furnished, and who performed the work.
Defined clinical pathways
General supervision does not remove professional accountability.
Physician / NPP context
Appropriate auxiliary clinical staff under applicable general-supervision requirements.
PT / OT context
Eligible therapist and appropriately supervised PTA / OTA within the therapy framework.
| Work | Appropriate distinction |
|---|---|
| Clinical review and management in a physician/NPP service | Qualified personnel under an applicable supervision and incident-to framework |
| PT/OT RTM | Eligible therapists and appropriately supervised PTAs/OTAs, with plan-of-care and modifier requirements |
| Shipping, appointment scheduling and eligibility checks | Administrative support, not automatically treatment-management time |
| Code selection and submission | The billing practice evaluates the full service evidence and payer rules |
The therapy pathway covers eligible therapists and appropriately supervised assistants, not unlicensed aides. CMS also explains that pharmacists, registered dietitians and athletic trainers do not have the Medicare benefit category needed to bill these remote-monitoring services.
The practice owns its clinical workforce and supervision. A technology vendor may supply tools or support a workflow, but that does not transfer responsibility for treatment decisions or establish that the vendor's work qualifies for a claim.
Can the same patient receive both RPM and RTM?
Clinically, a patient may have multiple needs. Medicare billing is a separate question: CMS does not permit concurrent RPM and RTM billing for the same patient. Using two vendors or counting different minutes does not remove that restriction.
For an RPM patient, CMS also limits billing to one practitioner in a 30-day period. Coordinate ownership and transitions so different organizations do not submit overlapping claims. For RTM, establish who owns the service and check the applicable CPT and payer limits rather than assuming every treating professional can separately bill the same monitoring work.
CMS permits RPM or RTM, but not both, alongside chronic care management, transitional care management, behavioral health integration, principal care management and chronic pain management when the applicable requirements are met and time and effort are not counted twice. Keep a record showing which activity supported which service.
Three decisions in practice
Blood-pressure management. A practice uses automatic home cuff readings to inform hypertension care and documents review and communication. Asking about medication adherence during that work does not turn the physiologic monitoring into RTM.
Musculoskeletal therapy response. A PT practice uses a qualifying therapeutic system to understand adherence and response to a prescribed exercise plan. The therapy plan of care, appropriate personnel and review and management records support that service—not the exercise assignment alone.
Two conditions, one billing-family decision. A patient needs blood-pressure follow-up and rehabilitation support. The treating teams decide which monitoring service they will furnish and bill under the applicable rules, coordinate ownership, and use other appropriate care pathways for the remaining needs. They do not submit concurrent RPM and RTM simply because the clinical questions differ.
Make the documentation tell the service story
A useful record connects the reason for monitoring to the equipment, data, review, patient communication and resulting plan. It also distinguishes clinical work from device logistics. A note saying “reviewed dashboard” does not explain what information was reviewed or how it informed care.
| Common failure | Better evidence |
|---|---|
| Diagnosis used as the sole program-selection rationale | The specific physiologic or therapeutic question |
| Generic app assumed to qualify | Exact product, intended use and qualifying data pathway |
| Every work-log minute counted | Personnel, clinical substance and time allocated once |
| Device days treated as management proof | Separate data-period and calendar-month management records |
| Two organizations independently billing monitoring | Coordinated ownership and a checked period before submission |
Revenue projections should follow this evidence, not precede it. Compare actual allowed amounts and collections with device, connectivity, clinical labor, supervision and administrative costs. Do not assume every enrolled patient produces every code every month.
Where FairPath fits
| Function | What your team owns | What FairPath records or surfaces |
|---|---|---|
| Program selection | Medical necessity and the physiologic or therapeutic question | Enrollment and patient context |
| Device evidence | Qualification, training and usable data | Device context associated with the patient |
| Clinical work | Workforce, supervision, review and treatment decisions | Clinical review queues and workspace context |
| Management documentation | Qualifying activities and live communication | Time and communication records |
| Period close | Family selection, coordination, code and claim decisions | Billing-review items for human assessment |
Organized records support review; they do not decide eligibility, replace the clinical team or guarantee payment.
Common questions
Is RTM just RPM for therapists? No. The core distinction is therapeutic adherence and response versus physiologic measurement. Personnel and therapy billing are additional considerations.
What if the patient's monitoring needs change? Coordinate which team owns the service, when the current service ends and how the new clinical need will be addressed. Check the applicable CPT and payer rules before billing a transition; do not assume a device change or a new vendor permits concurrent RPM and RTM claims.
Can a messaging app alone support RTM? Do not assume it can. Evaluate the medical-device framework, therapeutic category, data and actual service, not the presence of a chat feature.
Can software select the codes? Software may organize information, but the practice makes the code and claim decision against the complete evidence and applicable rules.
