RTM Software Total Cost of Ownership: Physitrack vs MedBridge vs Wibbi vs Limber Health

Snapshot: four billing models, four different answers

RTM (Remote Therapeutic Monitoring) vendors do not compete on a single headline price. They compete on four different ways of counting, and the vendor that looks cheapest at 20 patients often becomes the most expensive at 100. A clinic director comparing sticker rates alone will pick the wrong platform, because the billing unit itself changes the math more than the rate attached to it.

Each vendor counts differently. Physitrack bundles RTM into a $30 per user per month US subscription that also includes home exercise programs and Physicourses CEUs, then adds $8 per active patient. MedBridge charges a flat $10 per RTM episode at its group rate. Wibbi prices per code, from $10 to $27 depending on how much of the patient outreach its staff handle. Limber Health bills only when a patient hits a billable milestone, or offers $20 per month per engaged patient instead.

This piece is a cost model, not a feature review. It tells you what each platform will actually cost your clinic at 20, 50, and 100 active patients, and it shows the crossover points where one model overtakes another. Use it to build a defensible RTM budget and to walk into a vendor call knowing which numbers to challenge. The table below lays out every billing mechanic side by side before the volume projections.

Quick-reference cost comparison table

Each vendor prices RTM against a different billing unit, so a single number never tells the whole story. The table below shows the mechanic, the rate, what the fee covers, and the thresholds that change your real cost. Read it as the input to the volume models later in this piece, not as a ranking.

  Vendor Billing mechanic Price per unit What's included Notable minimums / thresholds     Physitrack Base subscription plus per-active-patient fee $30 per user/month, plus $8 per active patient HEP, RTM, and Physicourses CEUs bundled in the US base subscription Base fee applies per clinician seat. Per-patient charge triggers when a patient is active in RTM. RTM bundling is US-only.   MedBridge Per RTM episode (group rate) $10 per episode RTM episode billing on top of the platform subscription Two billable engagements per month clear a $63 reimbursement. Real cost per patient depends on episode length and touchpoints logged.   Wibbi Per code, with turnkey tiers $15 per code standard. Turnkey: $10 for code 98975, $20 for other codes, $27 for turnkey-plus Standard tier is self-managed. Turnkey-plus has Wibbi staff handle patient calls Turnkey-plus trades a higher per-code fee for reduced clinic labor. Cost scales with codes billed, not patient headcount.   Limber Health Utilization-based, or flat per engaged patient Billed on billable milestones, rounded down to 20-minute increments. Alternative: $20 per month per engaged patient RTM monitoring and engagement tracking You pay only when a billable milestone is reached under the utilization model. The flat option charges per engaged patient regardless of usage.  

Two definitions drive everything below. An active patient (Physitrack) and an engaged patient (Limber) are not counted the same way, and a MedBridge episode is a period of care rather than a monthly headcount. Confirm each definition with the vendor before you trust any total, because a clinic that logs two touchpoints a month per patient will model very different costs than one logging six.

How we modeled the numbers

The projections below rest on three assumptions, and each one moves the totals. Physitrack and Limber both bill per patient, but they count patients differently. Physitrack charges $8 per active patient, meaning any patient assigned a program in a given month. Limber's $20 alternative applies to engaged patients, those who actually complete monitored activity. We treated both counts as equal to the stated volume tier, which favors neither vendor.

For MedBridge and Wibbi, cost depends on how many billable touchpoints a clinic logs per patient per month. We modeled two billable engagements per patient monthly, the minimum needed to clear a $63 reimbursement under MedBridge's structure. Episode length shifts this, so a longer episode spreads fewer billable events across more months.

Confirm three inputs against your own clinic data before trusting these numbers. First, your real active-to-engaged patient ratio. Second, your average billable touchpoints logged per patient per month. Third, your typical episode length. Change any one and the cheapest vendor may change with it.

Annual cost at 20, 50, and 100 active patients

The tables below convert each vendor's billing mechanic into an annual dollar figure at three volume tiers, using the assumptions stated above. Physitrack's number combines one $30/user/month seat with the $8 per active patient charge. MedBridge assumes two billable engagements per patient per month at $10 each. Wibbi uses the $15 per code baseline with two codes billed monthly. Limber Health uses the $20/month per engaged patient rate.

20 active patients

  Vendor Monthly math Annual RTM cost     Physitrack $30 seat + (20 × $8) = $190 $2,280   MedBridge 20 × 2 × $10 = $400 $4,800   Wibbi 20 × 2 × $15 = $600 $7,200   Limber Health 20 × $20 = $400 $4,800  

50 active patients

  Vendor Monthly math Annual RTM cost     Physitrack $30 seat + (50 × $8) = $430 $5,160   MedBridge 50 × 2 × $10 = $1,000 $12,000   Wibbi 50 × 2 × $15 = $1,500 $18,000   Limber Health 50 × $20 = $1,000 $12,000  

100 active patients

  Vendor Monthly math Annual RTM cost     Physitrack $30 seat + (100 × $8) = $830 $9,960   MedBridge 100 × 2 × $10 = $2,000 $24,000   Wibbi 100 × 2 × $15 = $3,000 $36,000   Limber Health 100 × $20 = $2,400 $28,800  

Physitrack comes in lowest at all three tiers under these assumptions, and the gap widens as volume climbs because the $30 seat cost spreads across more patients. At 100 patients Physitrack's $8 rate produces $9,960 against Limber Health's $28,800, roughly a third of the utilization-based figure.

The comparison is not as clean once you change the billing inputs. MedBridge and Limber Health both land at the same annual figure at 20 and 50 patients here only because two $10 engagements happen to equal one $20 engaged-patient charge. Move MedBridge to a single billable engagement per month, and its cost halves to match a much leaner pattern. The MedBridge numbers above assume disciplined documentation of two engagements per patient. A clinic that logs fewer will pay less, and one that logs more will pay more.

Physitrack's headline advantage also carries a caveat worth stating plainly. The $30/user/month base is not an RTM-only fee. In the US bundle it includes the full home exercise program builder, RTM billing tools, and Physicourses CEU access. If you compare Physitrack's total against a competitor's RTM-only line item, you are comparing a bundled platform price against a single feature. A clinic that already pays separately for an HEP tool should read Physitrack's $2,280 at 20 patients as covering three functions, not one. Against a pure per-episode model with light documentation, MedBridge can undercut Physitrack, and the next two sections show exactly where that crossover sits.

Why Physitrack's per-active-patient model changes the calculus

Physitrack charges $30 per user each month for a US bundle that carries three products, then adds $8 for each active patient a clinician monitors. That base subscription includes the home exercise program platform, RTM, and Physicourses CEUs, so the $8 per active patient covers only the incremental monitoring cost on top of tools the clinic already uses daily. A single seat billed the same whether a clinician runs one RTM patient or ninety, and only the per-patient charge scales with volume.

Against Limber Health, the arithmetic favors Physitrack at every tier tested. Limber's flat alternative bills $20 per month for each engaged patient, more than double Physitrack's $8 per active patient. At 20 patients, 50 patients, and 100 patients, the per-patient gap widens the total the same way, and Physitrack stays the cheaper option before you even count the HEP and CEU value folded into the base subscription. A clinic paying Limber pays for monitoring alone. A clinic paying Physitrack pays for monitoring plus its exercise prescription and continuing education stack.

The comparison against MedBridge is where Physitrack can cost more, and the swing point is documentation habits rather than headline rate. MedBridge bills a flat $10 per RTM episode at the group rate, so a clinic that runs long episodes and logs the minimum billable touchpoints spreads that $10 across many reimbursable months. When a patient stays enrolled for a lengthy episode and the clinic bills few discrete engagements, MedBridge's per-episode fee undercuts Physitrack's recurring $8 per active patient per month.

Read that tradeoff for what it is. Physitrack's monthly per-patient charge buys the full clinical platform on top of RTM, while MedBridge's per-episode fee can win on RTM billing alone under long-episode, low-touchpoint patterns. Your own episode length and monthly touchpoint count decide which structure lands cheaper.

MedBridge's per-episode math: why it depends on your billing pattern

MedBridge charges a flat $10 per RTM episode at the group rate, and that single number hides most of the real cost. An episode is not a month or a patient. It is the full course of care from the first billable engagement to discharge, so a patient you monitor for eight weeks and a patient you monitor for four both count as one $10 episode. The per-episode price stays fixed while the clinical work behind it varies widely.

The reimbursement side is where the model earns its keep. Medicare pays roughly $63 for the primary RTM code once you log two billable engagements in a calendar month. You clear the $10 episode fee with room to spare after a single qualifying month, which makes MedBridge look cheap on paper. The catch is that you only capture that $63 if your clinicians actually document the two engagements every month the patient stays enrolled.

Episode length and documentation habits swing the true cost in opposite directions. A clinic that runs long episodes and logs reliable monthly touchpoints spreads that one $10 fee across many reimbursed months, so the effective cost per billable month falls close to nothing. A clinic that churns through short episodes pays $10 each time and captures fewer reimbursement cycles per fee, so the per-episode model gets less efficient the faster patients cycle through.

Of the four vendors here, MedBridge is the one whose real cost you cannot read off a rate card. It depends on your average episode length and how consistently your team logs the touchpoints that trigger reimbursement. Two clinics paying the identical $10 rate can land at very different annual costs, so model this one against your own documentation data before you trust any projection.

Wibbi's per-code and turnkey pricing

Wibbi charges per billed CPT code, starting at $15 per code on its standard plan. That structure ties your cost directly to what you submit, so a clinic logging one code per patient per month pays $15 per patient, while a clinic clearing multiple codes pays multiples of that. The rate scales with billing activity rather than headcount, which makes it predictable for clinics with consistent documentation and volatile for those whose touchpoints vary month to month.

The turnkey tiers reframe the decision as a labor question. Wibbi's basic turnkey option charges $10 for code 98975, the setup and education code, and $20 for other codes billed under the turnkey model. Turnkey-plus runs $27 per code, and at that tier Wibbi's own staff make the monthly patient check-in calls that generate billable monitoring time. You are paying a higher per-code fee in exchange for offloading the outreach that your own clinicians or admin staff would otherwise handle. Whether that trade favors you depends on your fully loaded staff cost per call, not the headline rate.

At the tested volumes, Wibbi's model rewards clinics that either log few codes per patient or genuinely lack the staff to chase monitoring time. A small practice billing one code per patient stays cheaper than Limber's $20 per engaged patient. At 50 or 100 patients logging multiple codes each, the per-code total climbs fast, and Physitrack's $8 per active patient on top of the $30/user/month bundle often lands lower. The turnkey-plus tier only pays off when the staff time it replaces would have cost you more than $17 per patient per month.

Limber Health's utilization-based billing

Limber Health bills only when a patient actually crosses a billable RTM milestone, and it rounds monitored time down to the nearest 20-minute increment before charging. A patient who logs 55 minutes of monitored activity in a month bills as 40 minutes, not 55. Limber offers an alternative flat rate of $20 per month per engaged patient, which trades the variable milestone math for a predictable line item.

Utilization-based billing means your RTM cost rises and falls with real patient activity rather than a fixed subscription. For cash flow, that cuts both ways. You never pay for a patient who stops engaging, which protects a clinic with high dropout. You also lose the ability to forecast a stable monthly number, since a strong engagement month costs more than a quiet one. Flat-rate competitors like Physitrack give you a predictable per-active-patient charge you can budget against months in advance.

At the volumes tested in this piece, Limber's $20 per engaged patient rate lands as the most expensive of the four models, because Physitrack's $8 per active patient undercuts it at every tier and MedBridge and Wibbi can beat it depending on episode and code patterns. A clinic might still choose Limber precisely because it pays only for genuine usage. If your patient panel churns hard, or you run short intake surges where many patients never reach a billable milestone, paying nothing for those patients can beat a flat per-patient fee that charges regardless of whether the patient ever engages.

Which billing model fits which clinic

Independent low-volume clinics running 20 or so active RTM patients should look hardest at MedBridge's per-episode model. When a clinic logs the two billable engagements needed to clear the $63 reimbursement, the $10 flat episode rate keeps monthly cost low and predictable. That advantage holds at the bottom tier, where per-patient fees add up slowly and staff can track a small caseload by hand.

Multidisciplinary practices mixing PT, OT, and SLP get more from Physitrack's bundle than from any pure RTM meter. The $30 per user each month covers a full home exercise program, PROMs, and Physicourses CEUs in the US, then adds $8 per active patient on top. A clinic that already needs an exercise prescription and engagement platform absorbs the RTM cost into tools its clinicians use daily, so the per-active-patient charge buys more than a billing line. At every volume tested, this structure came in below Limber's $20 per engaged patient, which makes Physitrack the stronger fit for practices that want one platform rather than a standalone monitor.

Enterprise health systems and multi-location networks should weight predictability and integration over the lowest headline rate. At 100 active patients, the flat-rate bundle scales cleanly, and Physitrack's Epic integration, ISO 27001, and ISO 13485 certifications matter to procurement teams that a solo clinic never thinks about. Limber's utilization billing appeals to a system that wants to pay only for patients who actually engage, but the crossover tables show that flexibility costs more than the flat models at higher volumes.

The pattern from the cost tables is straightforward. MedBridge wins at low volume when documentation is disciplined, Physitrack's bundle wins for multidisciplinary and multi-site buyers who need HEP plus RTM in one tool, and Limber's model suits clinics that prize usage-based flexibility over the cheapest total. Map your own caseload against the crossover points before you commit to any of them.

Questions to ask before you sign

Every vendor's headline rate hides variables that only surface once you model your own clinic's numbers. Bring these questions to any sales call so you can build the annual cost before you commit rather than after.

• How do you define a billable episode or engagement, and does it reset monthly or run for the full care episode?
• What is the minimum monthly commitment or minimum patient count, and am I charged for it during slow months?
• What is bundled into the base subscription, and what bills separately? Physitrack's $30 per user per month, for example, includes home exercise programs and Physicourses CEUs in the US, with RTM billed at $8 per active patient on top.
• How exactly do you count an "active" versus an "engaged" patient? A patient who logs one session and a patient monitored for 30 days may cost the same or wildly different amounts depending on the definition.
• For per-episode or per-code models, how many billable touchpoints do you assume per patient per month, and what happens to the price if my documentation habits produce more or fewer?
• Is there a per-seat clinician fee separate from the per-patient charge?
• For utilization-based billing, how are partial time increments rounded, and can you show me a sample invoice at my expected volume?

Ask for the math in writing. A vendor confident in their pricing will model it with you.

FAQs

What counts as an "active patient" for RTM billing?

An active patient is one who logs data or engages with their program during a given month, which is what triggers a billable RTM charge. Physitrack applies its $8 per-active-patient fee only to patients who actually use PhysiApp that month, so a discharged or dormant patient does not incur a charge. Confirm each vendor's definition, because "active" and "engaged" can mean different things across billing systems.

How do RTM reimbursement thresholds work?

Medicare pays RTM codes once a clinic logs the required number of qualifying engagements in a calendar month, commonly two, before billing the management code. That threshold is what clears roughly $63 per patient for the primary RTM management code. Confirm the current CPT code definitions and thresholds directly against Physitrack's RTM billing guide before relying on them, since reimbursement rules are updated periodically. Your software cost per patient only matters relative to that reimbursement, so model both sides together.

Do bundled platforms like Physitrack cost more than point solutions?

Physitrack's $30 per user per month base covers its 18,000+ exercise home program library, RTM, and Physicourses CEUs in the US, so the price reflects more than RTM billing alone. A pure RTM point solution can look cheaper on the RTM line but requires a separate home exercise tool. Compare total tooling cost, not the RTM fee in isolation.

How do I estimate my true RTM cost before committing?

Pull your real numbers on active patients per month, average billable touchpoints logged, and typical episode length. Run each vendor's model against those figures rather than the sticker rate.
