Cracking the RTM Billing Code: How PT Groups Stop Revenue Denials

Introduction

Remote Therapeutic Monitoring (RTM) has introduced an incredibly lucrative opportunity for outpatient physical therapy groups. By expanding reimbursement into the digital space, the Centers for Medicare & Medicaid Services (CMS) provided a clear path to improve plan of care adherence while adding high margin revenue.

But for many practices, the initial excitement of RTM has hit a frustrating obstacle: billing complexity.

Unlike standard in-clinic codes billed in predictable blocks, RTM codes depend on unique calendar-month tracking, strict data transmission thresholds, and distinct interactive communication rules. A single missed checkbox or unverified day can lead to swift denials from commercial payers and Medicare Administrative Contractors (MACs).

If your multi-site physical therapy group faces rising denial rates or operational pushback from frustrated billing teams, the issue is rarely a lack of clinical effort. The root problem is typically an outdated infrastructure trying to manage complex regulations manually. To protect your hard-earned revenue, you must understand where these billing workflows break down—and how using the right remote therapeutic monitoring software can systematically eliminate compliance risks.

Quick Answer: Eliminating RTM Billing Gaps in PT

Why is RTM billing so difficult for physical therapy practices, and how can it be fixed?

RTM billing is highly challenging because it requires tracking non-traditional thresholds across a 30-day period. For example, CPT 98977 requires at least 16 independent days of home data monitoring, while CPT 98980 requires a minimum of 20 logged clinical management minutes plus a live interactive call within the calendar month.

Physical therapy networks can eliminate denials by replacing manual tracking with specialized remote therapeutic monitoring software like SaRA. Automated platforms track transmission days, count clinical minutes down to the second, log patient consent, and verify that all billing criteria are met before a claim is exported to your EHR or billing clearinghouse.

The Core Pitfalls: Why RTM Billing Frequently Fails

To build an efficient billing workflow, physical therapy directors must target the precise regulatory points where RTM claims typically collapse.

1. The codes never get in the EMR

The VERY best rarely get over 80% of the potential billable RTM codes from SaRA into the EMR. Especially if the group is on an EMR where the "best practice" is putting the RTM codes into the next visit...

Well, what happens if the patients is gone for a week? Isn't seen for a week? The PT or PTA forgets to put the codes in?

We all know what happens... The codes do not get billed.

2. Billing teams are not equipped to effectively fight denials

We find ourselves over and over again sending United their own medical policy on RTM coverage. Especially if it is a subsidiary like a UMR!

Tracking down a denial that may come across as "non-covered charge" can feel like a wild goose chase with low ROI, unless you know exactly what you are looking for and if it is likely worth looking for at all.

The amount of time for a biller to check to see that "Oops" someone billed two 98977s within <30 days of each other is likely 30+ minutes, and then you start to wonder if that's the best use of that person's time.

3. No one knows the likely outcome

OK, that's not true. At SaRA Health, we do. We've been tracking this data for years across nearly every state and have a solid understanding of who will pay and who won't

Yet, if you start with us we will ecourage you to "submit and see" because payers change their minds (both ways) and you can never know for certain what is in your contract until you try.

Conclusion & Next Steps

Unlocking a sustainable, secondary revenue stream through Remote Therapeutic Monitoring does not have to overwhelm your clinical or billing teams. But, trying to make a square peg fit a round hole (i.e. billing these RTM codes thorugh your EMR) can cause chaos and destory potential net revenue.

By deploying SaRA across your clinics, you give your administrative teams the clean, validated, pre-audited data files required to secure rapid reimbursement and eliminate denials entirely.
