Remote Therapeutic Monitoring (RTM) | Billing in Physical Therapy — 2026 Update

Free Demo

A Conversation We Have Too Often

A physical therapy clinic owner in Texas asks us to review their billing. They’re running 200+ patient visits a month, seeing solid outcomes, and their patients are engaged. When we ask about RTM, the response is: “We set it up last year but we’re not sure if we’re billing it right. We only have a few patients enrolled.”

A few patients. Two hundred visits per month.

By the time we finish the audit, we’ve identified over $4,200 in monthly RTM revenue that should have been flowing into their practice and wasn’t.

Remote Therapeutic Monitoring is one of the most straightforward recurring revenue opportunities in physical therapy right now. It doesn’t require new patients. It doesn’t require additional clinical hours. It rewards practices for doing something they’re already doing: monitoring patient progress and staying engaged between visits.

But here’s the reality: most PT clinics either haven’t fully launched RTM, are running it without billing it correctly, or are leaving specific codes on the table every single month because the billing workflow was never properly configured.

With 2026 bringing meaningful updates to RTM coding including new CPT codes, clarified thresholds, and expanded commercial payer coverage there’s no better time to get this right. This guide covers everything you need to know, from the updated code set to the specific mistakes we see clinics making right now.

$125–$185 Average monthly RTM revenue per enrolled patient using the full CPT code stack	16 Days Minimum recorded data days required per billing period — the most commonly missed compliance threshold
~40% Of eligible PT patients are never enrolled in RTM despite qualifying the largest untapped revenue gap in most practices	$18,500+ Monthly RTM revenue potential for a practice with 100 actively enrolled and compliantly billed patients

RTM is a CMS-recognized service category that allows physical therapists, occupational therapists, and speech-language pathologists to bill for monitoring patients between clinical visits using digitally connected devices and platforms.

The key word is therapeutic. RTM is specifically designed for non-physiologic data pain levels, range of motion, functional status, therapy adherence, and musculoskeletal outcomes. This is what distinguishes it from Remote Patient Monitoring (RPM), which tracks physiologic data like heart rate or blood pressure and is tied to physician-led care.

That distinction matters a lot for physical therapy practices because RTM is the code set PTs can bill independently. No physician co-signature required. No transfer of billing rights. Your services, your revenue.

RTM vs RPM: The Difference That Changes Everything for PT Billing

⚠  The Confusion That Costs Clinics

We routinely see PT practices that have been told they can’t bill RTM because “that’s an RPM code and you need a physician.” That’s a mix-up between two separate programs.

RTM (98975–98981, 98985, 98979) is explicitly for non-physician providers. PTs have independent billing rights for RTM under CMS. Any billing advice telling you otherwise is outdated or incorrect.

2026 brought the most significant RTM coding changes since the program launched in 2022. Some of these updates expand revenue opportunity. Others tighten compliance requirements. All of them affect how you should be billing right now.

The practical implication of the 2026 updates: practices that updated their RTM billing workflows to reflect the new code set and documentation expectations are generating meaningfully more revenue per patient than those running the same setup they had in 2024. The opportunity window is now — before the commercial payer policy changes cycle into next year’s contract negotiations.

Here’s where most billing guides get overly technical. Let’s keep this practical. These are the codes, what they cover, and what you need to document to support each one.

💡 The Code Stack Strategy

The highest-performing RTM practices don’t pick one code — they stack appropriately. A typical compliant month looks like this: 98975 at setup, 98976 monthly for device supply, 98980 for the first 20-minute management block, 98981 when a second 20-minute block is documented, and 98979 for each 7-day period with documented asynchronous interaction.

Done correctly for 20 patients, that’s $3,200–$3,700 in monthly recurring revenue from patients who are already on your caseload.

Let’s run the real numbers. RTM revenue is recurring it generates every month for every enrolled patient who meets the engagement threshold. Unlike visit-based revenue, it doesn’t require a scheduled appointment or additional clinical time beyond what you’re already providing.

Active RTM Patients	Codes Billed	Rev/Patient/Month	Monthly RTM Revenue
5 patients	98975+98976+98980	~$125/patient	~$625/month
10 patients	98975+98976+98980	~$125/patient	~$1,250/month
20 patients	98975+98976+98980	~$125/patient	~$2,500/month
20 patients	Full code stack (+ 98981+98979)	~$185/patient	~$3,700/month
50 patients	Full code stack	~$185/patient	~$9,250/month
100 patients	Full code stack	~$185/patient	~$18,500/month

The $18,500 monthly figure for 100 patients isn’t a stretch goal. It’s what the math produces when every eligible code is billed correctly for every enrolled patient. Most practices with 100+ active patients on their caseload have far more RTM-eligible patients than they’ve enrolled.

What most PT clinics don’t realize is that the gap between their current RTM revenue and their RTM potential isn’t a clinical problem. It’s a billing workflow and patient enrollment problem. The patients are already there. The visits are already happening. The revenue is just not being captured.

Here’s where most PT clinics get it wrong. None of these mistakes require a dramatic system failure — they’re all quiet, recurring errors that show up on the books as lost revenue without an obvious cause.

Common Mistake	Revenue Impact	Why It Happens
Not billing 98975 at setup	Lost $19–$22/patient	Setup code skipped because staff assume it's optional
Missing 16-day data threshold	Full month claim denied	Patient engagement not tracked; claim submitted without confirming 16 days of data
Forgetting 98981 add-on	$39–$44 lost/month	Second 20-min management block never billed even when time is documented
Wrong supervision level documented	Audit / denial risk	General vs. direct supervision not specified in notes
Billing 98976 without device records	Overpayment / audit	Device data not attached to the claim record; payer flags for review
Mixing RTM and RPM codes	Systematic denials	98976 billed alongside RPM codes; payer rejects as duplicate service
No patient consent on file	Full program non-billable	RTM requires documented informed consent before first billable date
98979 not billed for async interactions	$16–$19 lost per 7 days	Asynchronous check-ins happen but nobody bills the online E/M add-on

💬 The 16-Day Rule Is the One That Gets Practices

We’ve seen well-run PT practices lose an entire month of 98976 reimbursement because a patient’s device recorded data on 15 days instead of 16. The clinical care was delivered. The patient was engaged. The claim just didn’t meet the threshold.

The fix is simple: track daily data recording per patient on a rolling calendar and flag any patient who hasn’t hit 14 days of data by day 22 of the billing period. That gives you a week to prompt the patient before the threshold is missed.

RTM audits are increasing as the program matures and payer volumes grow. The practices that get through audits cleanly are the ones that treat RTM documentation with the same rigor they apply to their clinical notes — not as an administrative checkbox.

Compliance Area	Requirement	Documentation Note
Patient Consent	Written informed consent before any RTM service begins	Document in EHR with date; verbal consent is not sufficient for billing
Device Data — 16 Days	Minimum 16 days of recorded data per 30-day billing period	Track per patient; do not bill 98976/98977 if threshold not met
20-Minute Rule	98980 requires at least 20 minutes of interactive communication	Time must be documented with start/end or total minutes in clinical note
Qualified Provider	98980/98981 billed by QHP — PT, OT, or SLP independently	Under general supervision, support staff may assist with data review
Clinical Documentation	Notes must reflect clinical reasoning tied to RTM data reviewed	RTM notes cannot be generic; must connect data findings to care plan
Async Interactions	98979 requires documented digital communication with patient	Platform records or EHR message logs serve as documentation
Device Compatibility	Device must be FDA-authorized for its indicated monitoring purpose	Confirm device classification before program launch; document in file

One point worth emphasizing: the clinical note for RTM services needs to demonstrate that you actually reviewed and used the data. A note that says “Reviewed RTM data. Patient progressing.” will not hold up in a payer audit. The note should describe what the data showed, how it informed your clinical thinking, and what if anything changed in the care plan as a result.

This isn’t about documentation for documentation’s sake. It’s the clinical justification that makes the service defensible and the reimbursement secure.

After working through RTM billing audits with practices across the country, the underperformance almost always traces back to the same handful of structural gaps — not clinical gaps.

No Defined Enrollment Workflow

RTM revenue only flows for enrolled patients. But in most practices, enrollment is informal some therapists enroll their patients, others don’t, and nobody owns the process systematically. There’s no point in the clinical workflow where RTM eligibility is assessed and enrollment happens automatically.

Fix: Build RTM eligibility assessment into the initial evaluation for every patient. Document the decision — enrolled or not enrolled and why. Make it a standard step, not a case-by-case judgment.

Billing Staff Not Trained on RTM Specifics

RTM codes have specific threshold requirements that are different from standard PT billing. The 16-day rule, the 20-minute management threshold, the add-on code structure these require dedicated training. When RTM claims are handled by staff who apply general PT billing logic to an RTM-specific code set, the errors follow predictably.

Fix: Separate RTM claim review from standard visit billing. Designate a specific person or workflow checkpoint for RTM claims, with a review of device data records and time documentation before submission.

No Monthly Recurring Revenue Tracking

Most PT practices track revenue by visit. RTM is a monthly recurring model — it generates revenue independently of visit frequency. When practices don’t track RTM revenue separately, they can’t see what’s being missed, and nobody’s accountable for the gap.

Fix: Add RTM revenue as a separate line in your monthly financial reporting. Track enrolled patients, billing compliance rate, and revenue per enrolled patient. When those numbers are visible, the gaps become obvious.

If your practice isn’t fully leveraging RTM billing, you’re leaving recurring monthly revenue on the table — revenue that requires no additional clinical effort beyond what your therapists are already providing.

The challenge is that RTM billing has enough moving parts — enrollment workflows, data threshold tracking, code stacking, documentation specificity, payer-specific coverage rules — that managing it correctly requires dedicated expertise. For most PT practices, that expertise doesn’t exist in-house.

Partnering with a billing team that specializes in physical therapy and RTM specifically means the code stack is optimized, the compliance documentation is structured correctly, and the monthly revenue flows consistently without adding to your administrative workload.

Remote Therapeutic Monitoring is one of the clearest revenue opportunities in physical therapy right now. The codes exist. CMS and commercial payers are paying. The patients are already in your practice. The clinical work is already happening.

What’s missing in most clinics is the billing infrastructure that turns all of that into consistent, compliant monthly revenue. The enrollment workflow. The code stack. The data tracking. The documentation specificity. The monthly review that catches gaps before they become missed revenue.

With the 2026 code updates particularly CPT 98985 and 98979 and the expansion of commercial payer coverage, the opportunity is larger than it’s ever been. The practices that build their RTM billing correctly this year will have a recurring revenue line that compounds as their caseload grows.

The Bottom Line

Scaling RTM revenue doesn’t require more patients or more clinical hours. It requires a billing workflow built specifically for RTM — one that enrolls eligible patients systematically, bills the complete code stack monthly, tracks compliance thresholds proactively, and documents in a way that holds up under payer scrutiny.

If your practice has eligible patients who aren’t enrolled, or enrolled patients who aren’t generating their full monthly reimbursement, that gap is recoverable. It just needs the right billing infrastructure behind it.
