RTM billing basics
RTM management needs minutes and a live interaction
Direct answer
Remote therapeutic monitoring (RTM) management requires both qualifying time and a live interaction. A minute total does not establish that the interaction happened. The interaction contributes to the total, but it need not fill every reported minute. These are separate record checks, not separate blocks of time to add twice.
Scope: US Medicare Part B Physician Fee Schedule (PFS), effective January 1, 2026. Reviewed October 17, 2026. This guide addresses patient contacts only.
The Centers for Medicare & Medicaid Services (CMS) explains this distinction in its 2026 final rule, 90 FR 49397, section II.E.(32). Neither check, alone or together, establishes that every requirement for billing has been met.
A hypothetical month-end review
Imagine a physical therapy clinic reviewing September 2026 records. This is an invented example, not a patient story.
One record shows 24 minutes labeled as management work. Its only contact entry says the therapist left a voicemail. There is no note describing an exchange with the patient.
A second record describes a six-minute conversation about the patient's exercise difficulties. It records the patient's questions and the therapist's responses. The rest of the month's time record is blank.
The records need different follow-up. The first has a time total without evidence of a live exchange. The second describes an exchange without enough recorded time to establish the relevant total. Neither record lets the biller assume the missing part.
The 10-minute code still needs an interaction
Medicare rule, effective January 1, 2026: Code 98979 introduces a 10-minute starting point for RTM management. It still requires at least one real-time exchange during the calendar month. See CMS MM14250, page 2, released November 24, 2025.
The 2026 final rule, 90 FR 49397, section II.E.(32) also says 98979 and 98980 are not additive. They cover the first 10 and first 20 minutes, respectively. They are not two amounts to stack together.
CMS's live-interaction explanation covers 98979, 98980, and 98981. The introduction of a shorter time option does not replace that requirement.
Nor does the rule require every reported management minute to be a conversation. The live exchange counts toward the total. Whether other work belongs in that total remains a separate question.
Recommended tool: a two-part record check
Use this card to identify what needs review, not to approve a claim. It is our suggested review method, not a CMS form or an official list of required note fields.
Keep both parts visible for the same calendar month. Do not turn them into a compliance score.
| Record check | Evidence to examine | What remains unknown | Recommended next action |
|---|---|---|---|
| 1. Management time | Look at the underlying entries, not only the total. Compare the recorded activities, dates, person doing the work, and durations. | A total alone does not establish which activities qualify. It also does not establish that a live exchange occurred. | Check each uncertain entry against applicable requirements. Look for duplicated time. Verify that the live exchange was included only once. |
| 2. Live patient interaction | Look for a record describing an actual exchange. Distinguish it from a scheduled call, an unanswered call, or a voicemail. | Contact evidence alone does not establish enough qualifying time. A completed-contact label without supporting detail leaves the event unclear. | Locate the underlying note. Clarify unresolved facts with the treating clinician. Keep unsupported conclusions out of the billing decision. |
The useful output is a specific unresolved question. For example: "Did a live exchange occur in September, and where is its record?" Or: "Which entries support this month's qualifying time total?"
Those questions point to different records. Rechecking the arithmetic cannot answer the first one. Finding a conversation note cannot settle every activity in the second.
A contact attempt is not a completed exchange
Observation about the record: A voicemail is evidence of attempted contact, not evidence of a two-way interaction.
Ordinary asynchronous texts are messages answered later, rather than a live exchange. A thread can contain replies without showing that the participants interacted in real time.
Source boundary: This is not a claim that CMS published a blacklist of messaging channels. In 90 FR 49397, section II.E.(32), CMS adopts the live-interaction requirement without specifying further communication exclusions beyond the applicable code requirements.
The distinction works in both directions. A live conversation does not make every review, text, or voicemail minute eligible. Each activity still needs assessment under the applicable requirements.
This guide does not determine eligibility for every communication technology or category of work. Its narrower question is whether the record supports the conclusion being drawn from it.
Match the follow-up to what is missing
Recommendation: Distinguish missing documentation from an interaction that did not happen. An absent note does not prove there was no conversation. It does mean the reviewer lacks evidence for that conclusion.
If a conversation occurred, look for its actual record before deciding what remains unresolved. If it never happened, do not record it as completed. A later month's conversation is not evidence of an exchange in the earlier month.
Do not arrange contact solely to reach a billing target. Services must be clinically warranted. CMS reinforces the requirement for reasonable and necessary services in the 2026 final rule, 90 FR 49396, section II.E.(32).
If the reporting period itself is unclear, read RTM: 30 days versus the calendar month. Resolve that question before comparing the time and contact records.
This two-part check does not replace the clinic's billing review. Other payer and code requirements remain. It does not establish acceptance by a commercial insurer or a Medicare Advantage plan.
For your next record review, name the missing evidence before choosing the next action. More minutes cannot stand in for a live interaction. A live interaction cannot stand in for the rest of the time evidence.
