Medicare RTM Requirements: Eligibility, Billing, and Reimbursement

Remote Therapeutic Monitoring has become a meaningful revenue stream for rehab clinics. CMS defines the RTM codes and their requirements. Commercial payers vary mainly in how they accept and reimburse them. The rules clinics relied on last year have also shifted with the 2026 code updates.

This guide covers what rehab clinics need to know to bill Medicare for RTM with confidence. We cover which providers and patients qualify under Medicare’s rules, how the 2026 CPT codes apply, and how reimbursement works. The documentation and billing actions for RTM stay largely consistent across payers. Medicare sets the most established framework, and most commercial insurers follow it with their own variations.

Medicare’s guidance has continued to evolve since RTM launched. For 2026, a new code structure materially changes what clinics can bill and when. Staying up to date on these rules is the difference between a clean claim and a denial.

What Medicare Considers Remote Therapeutic Monitoring

Medicare defines RTM as the remote monitoring of non-physiological patient data. This includes musculoskeletal status, respiratory status, therapy adherence, and therapy response. A qualifying monitoring platform or device must collect the data. A qualified clinician then reviews it within an active plan of care.

RTM differs from Remote Patient Monitoring (RPM). RPM covers physiological data that connected devices capture, such as blood pressure, glucose, and heart rate. The distinction matters for two reasons. It shapes which clinicians can bill, and it shapes which patient data actually qualifies.

For rehab clinics, RTM fits how they already work. It tracks exercise adherence, pain levels, functional status, and patient-reported recovery. RPM, by contrast, suits chronic disease management workflows in primary care and cardiology settings.

Which Providers Can Bill Medicare for RTM

Medicare recognizes several provider categories as eligible to bill RTM codes, but the picture isn’t uniform across disciplines.

Physical therapists and occupational therapists qualify clearly and hold the strongest track record with RTM reimbursement under Medicare. Physicians and other qualified healthcare professionals also qualify.

Speech-language pathologists count as qualified healthcare professionals under the RTM framework. In practice, though, Medicare reimbursement for SLP-billed RTM has been inconsistent. SLP clinics interested in RTM should verify eligibility with their Medicare Administrative Contractor before building a billing workflow. Confirm coverage at the patient level rather than assume payment will follow.

Medicare does not currently cover chiropractors for RTM. Chiropractic clinics can still pursue RTM reimbursement through commercial insurance, workers’ compensation, auto insurance, and cash-pay arrangements. For them, though, Medicare is not part of the equation today.

The “incident to” language within RTM definitions is one area where rehab clinics often run into trouble. The “incident to” framework most billers know grew out of physician practices. In that setting, unlicensed staff can deliver services under direct physician supervision. Therapy services don’t work that way. PTs, OTs, and SLPs follow their own supervision rules under state practice acts and Medicare’s therapy benefit. Those rules govern who can deliver and bill for RTM work in a therapy setting. When clinics structure RTM around a supervising clinician, they should map it to therapy supervision rules first. The physician “incident to” template doesn’t apply.

Therapy assistants (PTAs, COTAs, and SLPAs) can perform much of the day-to-day RTM work. This includes enrolling patients, monitoring data, and communicating with patients about their home program. The one condition: the evaluating therapist must document medical necessity for RTM in the initial evaluation.

When an assistant delivers the service, the clinic must bill the corresponding code with the appropriate assistant modifier. Use CQ for PTAs and CO for COTAs. The modifier triggers the reduced payment rate. This applies to 98975 and the treatment management codes 98979, 98980, and 98981. Clinics building RTM workflows around assistant involvement should plan for the modifier requirement and the reimbursement adjustment from the start.

Patient Eligibility Requirements

Medicare requires that RTM be tied to a treatable condition and an active plan of care. The service has to support a clinical purpose connected to the patient’s treatment, not function as general wellness monitoring.

Coverage for rehab RTM typically falls under Medicare Part B, since Part B is the layer that covers outpatient therapy services. Part A coverage applies in different settings (inpatient, skilled nursing, hospice), and the rules for monitoring patients in those settings differ from outpatient RTM. Clinics billing RTM in any non-standard setting should verify which Medicare benefit applies before submitting claims.

Patient consent is required before RTM billing begins. The consent needs to document that the patient understands the service, the associated cost-sharing, and the option to discontinue.  This needs to be captured before the first billable interaction, not after the fact.

Patients also need to be capable of using the monitoring platform or device. RTM data must be transmitted through the platform; informal self-reports during phone calls or office visits don’t qualify for the device supply codes.

The Six RTM CPT Codes Under Medicare

Medicare recognizes six RTM codes in 2026, covering initial setup, device or platform supply, and treatment management time. The figures and code structure below align with Wibbi’s 2026 RTM CPT code overview, though clinics should always cross-check against the current CMS Physician Fee Schedule before submitting claims, since this is the section most prone to misinterpretation.

The 2026 update introduces two changes clinics should understand. 98985 gives clinics a way to bill device supply when monitored data falls in the 2–15 day range, sitting alongside 98977 which still covers the 16–30 day range. 98979 provides a shorter management time code for months when clinician oversight lands between 10 and 19 minutes, below the 20-minute threshold that triggers 98980.

Together, these additions give clinics more accurate ways to capture shorter monitoring periods and shorter management windows than the previous code structure allowed.

A practical example of how the codes stack: a patient enrolled at the start of the month who transmits 16+ days of data and receives 25 minutes of management time could generate 98975 (once per episode), 98977, and 98980, roughly $115 in that first month, with recurring revenue from 98977 and 98980 (and potentially 98981) in subsequent months for as long as the patient remains engaged.

Across a panel of actively engaged RTM patients, this becomes meaningful recurring revenue tied to work many rehab clinics are already doing informally.

^{*Note: Under 98979–98981, management time can be accumulated across all licensed therapists involved in a patient’s care during the calendar month, it doesn’t have to come from a single clinician. If a therapy assistant (PTA or COTA) performs more than 10% of that monthly management time, the de minimis rule kicks in and the claim must be submitted with the appropriate assistant modifier (CQ for PTAs, CO for COTAs), triggering the reduced payment rate.}

Common Medicare RTM Billing Mistakes to Avoid

A few mistakes show up consistently when clinics start billing Medicare for RTM:

• Billing 98977 without meeting the 16-day monitoring threshold within the 30-day window, one of the most frequent denial triggers
• Double-billing RTM alongside overlapping care management codes (CCM, PCM, BHI) for the same patient in the same calendar month
• Missing or incomplete consent documentation, which makes the entire RTM claim vulnerable in audit
• Time logs that don’t tie back to specific RTM activities or to the plan of care, making the management time codes hard to defend
• Reconstructing time at month-end instead of logging it as work happens

Most of these mistakes trace back to manual tracking. Clinics that rely on spreadsheets and end-of-month documentation eventually run into denial patterns that don’t resolve until the underlying workflow changes.

Building a Compliant Medicare RTM Workflow

A compliant Medicare RTM workflow starts at enrollment and runs through billing. The pieces that matter most: consent capture at the start of the program, device or platform assignment tied to the patient’s plan of care, a monitoring schedule that meets the relevant day thresholds, and tracked management time logged as the work happens.

Different roles touch the workflow at different points. Clinicians own enrollment decisions, ongoing data review, and management time. Front-desk staff often handle consent capture and onboarding logistics. Billing teams manage submission and follow up on denials. When each role has a defined responsibility, gaps that lead to denials become much less common.

The right platform reduces the manual layer that creates most of the risk. Instead of tracking monitored days in a spreadsheet or estimating management time at month-end, clinics can run RTM on a system that captures qualifying data automatically and converts it into billing-ready documentation when each threshold is met. EMR integration keeps RTM documentation tied to the plan of care, which is where most audits start.

How Wibbi Supports Medicare-Compliant RTM

Wibbi is built around the specific requirements Medicare attaches to RTM, not a generic monitoring framework adapted after the fact. On the eligibility side, the platform supports the patient-level checks Medicare expects before billing begins: documented consent, linkage to an active plan of care, and confirmation that the patient is using the monitoring platform rather than self-reporting informally. These prerequisites are captured at enrollment so they’re in place before the first billable interaction not reconstructed at month-end.

On the billing side, Wibbi tracks monitored days against the device supply code thresholds (the 2–15 day window for 98985 and the 16–30 day window for 98977) and management time against each treatment management code threshold (98979, 98980, 98981). When a patient meets the requirements for a given code, the documentation automatically converts into a billing-ready record built around what Medicare expects in an audit: plan-of-care linkage, specific activities logged, and time tied to qualified clinician work.

Wibbi meets FDA regulatory requirements for RTM, one of the underlying requirements for the platform to qualify under the RTM framework. Beyond the platform itself, Wibbi helps clinics set up and operationalize Medicare RTM programs end-to-end across rehab disciplines from initial workflow design through ongoing compliance.
