Remote Patient Monitoring (RPM) CPT Billing in 2026: New Codes, New Thresholds, What Changed
A practice sets up remote monitoring for a patient recovering from a recent hospital discharge, and by day 14 the patient has transmitted solid data every single day — but under the old rule, that fell one day short of the 16-day threshold required to bill for the device supply at all. That specific gap is exactly what CMS addressed for 2026, and it's the most consequential RPM billing change in several years.
This guide covers the two new RPM codes added for 2026, the lowered setup threshold, how the new short-cycle codes interact with the original ones, and where RPM billing most commonly goes wrong.
QUICK ANSWER • CMS finalized two new Remote Patient Monitoring codes for 2026: CPT 99445, covering device supply with 2–15 days of data transmission in a 30-day period, and CPT 99470, covering the first 10 minutes of monthly interactive management time. These sit alongside the original codes — 99453 (initial setup), 99454 (device supply, 16–30 days of transmission), 99457 (first 20 minutes of monthly management), and 99458 (each additional 20 minutes) — which remain in place with their structure unchanged. Separately, CMS lowered the 99453 setup threshold, now requiring as few as 2 days of monitoring data to qualify for reimbursement. The new short-cycle codes cannot be billed alongside their longer-threshold counterparts in the same period, and commercial payer adoption of the 2026 changes varies — verify each payer's current policy before applying the new codes outside Medicare. |
The Complete 2026 RPM Code Set
CPT Code | What It Covers | Billing Frequency | Key 2026 Note |
99453 | Initial device setup and patient education | One-time, per episode of care — not repeated monthly for the same patient and condition | Threshold lowered under the 2026 CMS final rule to as few as 2 days of monitoring data to qualify |
99454 | Device supply with 16–30 days of data transmission in a 30-day period | Billed once per 30-day period | Cannot be billed in the same period as 99445 |
99445 (new for 2026) | Device supply with 2–15 days of data transmission in a 30-day period | Billed once per 30-day period | Mutually exclusive with 99454 — select one based on actual days of transmission, not preference |
99457 | First 20 minutes of monthly interactive management time | Billed per calendar month, not per 30-day device cycle | Requires real-time, synchronous two-way communication with the patient or caregiver |
99470 (new for 2026) | First 10 minutes of monthly interactive management time | Billed per calendar month | Cannot be billed in the same month as 99457 — select one based on actual time, not habit |
99458 | Each additional 20 minutes of monthly management time beyond the first 20 | Add-on to 99457 only, unlimited monthly increments where genuinely supported by time | Cannot function as an add-on to 99470 — verify current guidance on how additional time is billed under the shorter-threshold pathway |
The two new codes don't replace anything — they fill a gap. Before 2026, a patient who transmitted data for 10 days in a 30-day period, or whose care team spent 12 minutes on monthly management, generated no billable device or management code at all under the original thresholds. 99445 and 99470 make that lighter-touch monitoring billable for the first time.
Why This Change Matters Clinically, Not Just Financially
The original 16-day and 20-minute thresholds worked reasonably well for patients on long-term, daily monitoring programs — chronic heart failure, long-term hypertension management. They worked poorly for shorter, episodic monitoring needs: post-discharge transitional monitoring, medication-titration windows, or conditions where daily engagement is clinically harder to sustain. The 2026 codes are specifically aimed at making those shorter-duration, lighter-touch monitoring relationships billable rather than clinically appropriate but financially unsupported.
RPM Code Selection Decision Framework
Question | If the Answer Is... | Action |
How many days of data were transmitted this 30-day period? | 2–15 days | Bill 99445 (new for 2026) — do not also bill 99454 |
How many days of data were transmitted this 30-day period? | 16–30 days | Bill 99454 — do not also bill 99445 |
How many minutes of interactive management time this calendar month? | 10–19 minutes | Bill 99470 (new for 2026) — do not also bill 99457 |
How many minutes of interactive management time this calendar month? | 20+ minutes | Bill 99457, plus 99458 for each additional full 20-minute increment genuinely supported by documented time |
Is this the patient's first device setup for this monitoring episode? | Yes, and at least 2 days of data now exist | 99453 may be billable, per the 2026 threshold — verify current guidance before assuming automatic eligibility |
Is this a commercial payer rather than Medicare? | Commercial payer | Verify that payer's specific policy — adoption of 99445/99470 varies, and some payers still require the traditional 16-day/20-minute thresholds |
BILLING RED FLAG The New Codes Are Alternatives, Not Additions • 99445 and 99454 are mutually exclusive within the same 30-day period — bill one or the other based on actual transmitted days, never both. The same logic applies to 99470 and 99457 within the same calendar month. Treating the new codes as bonus billing opportunities stacked on top of the originals, rather than as alternate pathways selected based on actual thresholds met, is the most likely new source of RPM denials in 2026. | ||
The Interactive Communication Requirement
CPT codes 99457, 99458, and 99470 all require real-time interactive communication with the patient or caregiver to count toward the billed time — reviewing transmitted data alone, without that live interaction, does not satisfy the requirement. CMS has previously defined interactive communication for these codes as real-time, synchronous two-way audio interaction, capable of being enhanced with video — a standard that has excluded asynchronous text messaging.
There has been some indication that future CPT manual language could address this definition further. Until that's confirmed through current CMS and AMA guidance, don't assume text-based check-ins satisfy the interactive communication requirement for these codes — verify the current-year definition before counting that time.
Commercial Payers Are Not Moving in Lockstep With Medicare
Medicare finalized the 99445 and 99470 code additions for 2026, but commercial payer adoption has been inconsistent. Some commercial payers have continued requiring the traditional 16-day transmission and 20-minute time thresholds even after CMS's change took effect, rather than recognizing the new shorter-cycle codes. Applying the new codes to a commercial claim without confirming that specific payer has adopted them is a straightforward, avoidable denial risk.
Before rolling the new codes into your billing workflow for any non-Medicare payer, verify current policy directly with that payer rather than assuming universal adoption.
Common RPM Billing Errors
Error | Why It Happens | Prevention |
Billing 99454 and 99445 in the same 30-day period | Both describe device supply for the same monitoring cycle, distinguished only by days of data transmitted — they're mutually exclusive | Count actual transmitted days first, then select the single code that matches |
Billing 99457 and 99470 in the same calendar month | Both describe the base tier of monthly management time, distinguished by minute threshold — not stackable together | Confirm actual documented minutes, then bill only the code matching what was performed |
Treating text messages as interactive communication | CMS has previously defined interactive communication for these codes as real-time, synchronous two-way audio, capable of being enhanced with video — a stricter standard than asynchronous messaging | Verify current CMS and CPT manual language before counting text-based check-ins toward the time threshold |
Assuming 99453 is billed monthly like the device and management codes | 99453 is a one-time setup code per monitoring episode, not a recurring monthly charge | Bill 99453 once when the episode begins, not with every subsequent monthly cycle |
Assuming commercial payers automatically adopted the 2026 code changes | Medicare finalized 99445 and 99470, but commercial payer adoption has been inconsistent — some payers, per current reporting, still require the traditional 16-day/20-minute thresholds | Verify each commercial payer's current RPM policy before applying the new short-cycle codes to non-Medicare claims |
Misaligning 99454 and 99457/99458 billing cycles | 99454 is tracked per 30-day device period while 99457/99458 are tracked per calendar month — these aren't always the same window | Reconcile both cycles carefully rather than assuming they align automatically; consider submitting related RPM claims together |
Insufficient documentation of medical necessity | RPM requires an ongoing, medically reasonable and necessary basis for monitoring, not just device availability | Document the specific clinical justification for remote monitoring at program initiation and periodically thereafter |

Frequently Asked Questions
What are the new RPM CPT codes for 2026?
CPT 99445, covering device supply with 2–15 days of data transmission in a 30-day period, and CPT 99470, covering the first 10 minutes of monthly interactive management time. Both were finalized by CMS to fill gaps the original 16-day and 20-minute thresholds left uncovered.
Can CPT 99454 and 99445 be billed together?
No. They're mutually exclusive within the same 30-day period — select whichever code matches the actual number of days the patient transmitted data.
Can CPT 99457 and 99470 be billed together?
No. They both describe the base tier of monthly interactive management time, distinguished by the minute threshold met — select one based on documented time, not both.
What changed with CPT 99453 for 2026?
CMS lowered the threshold for the initial setup code, now requiring as few as 2 days of monitoring data to qualify for reimbursement, down from the prior requirement — opening RPM billing to patients with shorter or more episodic monitoring needs.
Do commercial payers cover the new RPM codes?
It varies. Medicare adopted 99445 and 99470 for 2026, but commercial payer adoption has been inconsistent — some continue requiring the traditional 16-day/20-minute thresholds. Verify each payer's current policy before applying the new codes to non-Medicare claims.
Does reviewing transmitted RPM data count toward the management time codes?
Generally no, on its own. CPT 99457, 99458, and 99470 require real-time interactive communication with the patient or caregiver, historically defined by CMS as synchronous two-way audio — data review without that live interaction doesn't satisfy the requirement.
Is CPT 99453 billed every month?
No. It's a one-time code for the initial device setup and patient education at the start of a monitoring episode, not a recurring monthly charge.
How are 99454 and 99457 billing cycles different?
99454 is tracked per 30-day device supply period, while 99457 and 99458 are tracked per calendar month — these windows don't always align exactly, so reconcile them carefully rather than assuming they're the same cycle.
