A complete guide to RPM CPT codes for 2026, including the new 99445 and 99470 codes, reimbursement rates, and the rules that trip up most practices.
For years, RPM billing came down to a simple rule: hit 16 days of data transmission or don't bill at all. The CY 2026 Medicare Physician Fee Schedule broke that binary open, adding two new codes that let practices bill for shorter monitoring windows and lighter management time. That's good news for revenue capture - but it also means practices still applying the old 16-day-only rule are leaving reimbursement on the table every month.
What Are the RPM CPT Codes for 2026?
Six CPT codes now cover remote patient monitoring, split into device-supply codes and treatment-management codes:
- 99453 - Initial device setup and patient education, billed once per episode, not monthly
- 99454 - Device supply with data transmission for 16 or more days in a 30-day period
- 99445 - New for 2026, device supply for 2–15 days of transmission in a 30-day period
- 99457 - First 20 minutes of monthly treatment management time, requiring live interaction
- 99458 - Add-on code for each additional 20 minutes beyond 99457
- 99470 - New for 2026, covers the first 10 minutes of management time, a lower threshold than 99457
RPM Setup and Device Supply CPT Codes: 99453, 99454, and 99445
CPT 99453 covers initial setup and patient education and is billed once per episode, regardless of how many devices are involved; it cannot be billed more than once per month per patient, even when multiple devices are supplied in the same period.
Device supply itself splits into two codes based on transmission volume. Before 2026, a patient who transmitted data for only 10 days in a 30-day period generated unbillable data - the practice had done real monitoring work with nothing to show for it. CPT 99445 closes that gap, covering the 2–15 day window that previously fell through the cracks.
The 16-Day Rule vs. the 2-Day Rule
This is the most common new-code error: 99445 and 99454 cover the same device-supply function at different transmission thresholds, and you can't bill both for the same patient in the same 30-day period. If a patient transmits 16 or more days, bill 99454. If they transmit 2–15 days, bill 99445 instead - never both.
Per CMS's remote patient monitoring coverage rules, the correct code depends entirely on actual transmission days that month, not on which code was used previously. A patient hitting 18 days one month and 12 days the next requires switching codes between billing cycles.
RPM Management CPT Codes: 99457, 99458, and 99470
Once device-supply billing is settled, monthly management time determines the second half of RPM reimbursement. CPT 99457 covers the first 20 minutes of management time; 99458 adds up to two additional 20-minute increments, once at 40 minutes and once at 60. CPT 99470, new for 2026, addresses management time the same way 99445 addressed device supply - covering just 10 minutes of monthly work, a lower threshold than 99457's 20-minute requirement.
Choosing between 99457 and 99470 isn't about picking whichever pays more; it's about which threshold the documented time actually supports that month. Billing 99457 when only 12 minutes of genuine management time occurred is the kind of pattern that draws audit attention, regardless of intent.
Real-Time Interaction Requirements for RPM Billing
CMS has reaffirmed across all three management codes - 99470, 99457, and 99458 - that at least one real-time interaction is required to bill. Phone and video communication both count, but passive data review alone, without a live touchpoint with the patient, doesn't meet the threshold no matter how much time was spent analyzing the data.
Billing RPM Alongside CCM and Other Care Management Programs
RPM billing rarely happens in isolation. Practices running RPM alongside Chronic Care Management for the same patients see measurably better outcomes than either program alone - RPM vs CCM: optimal patient outcomes have been associated with significantly greater blood pressure reduction compared to RPM by itself, which matters both clinically and for justifying concurrent billing.
Confirming which program a given patient is actually eligible for matters just as much as billing accuracy. Remote patient monitoring pros, cons, and benefits come down to what's actually being tracked - physiologic device data versus care coordination versus therapy adherence - and mixing these up leads to selecting the wrong code family entirely, not just the wrong specific code.
G2211 and Other Add-On Codes for RPM Visits
Longitudinal RPM relationships often qualify for billing beyond the core RPM codes themselves. CPT code G2211 billing and reimbursement rates recognizes the ongoing value of a continuous care relationship and can apply to visits connected to an active RPM program, capturing revenue that pure device-and-time billing alone misses.
Documentation Requirements for the New 2-Day Code
Because 99445 is new enough that many billing teams haven't fully operationalized it yet, this guide on the RPM code for 2-15 days of data transmission - what counts as a transmission day, how to track the threshold mid-cycle rather than discovering it at month-end - is worth reviewing directly rather than assuming it works identically to 99454.
How to Stay Compliant With CMS RPM Requirements
These 2026 additions reflect a broader shift covered in CMS's proposed rule for simplified RPM - rewarding monitoring that's genuinely happening, even when it doesn't fit the original 16-day, 20-minute framework designed years before shorter monitoring episodes and lighter-touch check-ins became common practice. These changes were finalized in the CY 2026 Medicare Physician Fee Schedule final rule, which practices should reference directly when confirming current thresholds.
How Circle Health Fits Into This Picture
RPM is one of Circle Health's core solutions, and getting these six CPT codes applied correctly every month is exactly the operational challenge Circle Health's AI-powered platform is built to solve. Rather than requiring billing staff to manually track transmission-day counts and management-time thresholds across an entire patient panel, Circle Health's licensed care managers and automated documentation capture the correct code - 99454 or 99445, 99457 or 99470 - based on what actually happened that month, reducing the mutual-exclusivity errors and audit exposure that manual tracking commonly produces. This same accuracy applies when weighing Circle Health against other options, including this ThoroughCare review: pricing and features for practices evaluating software-only alternatives.
Conclusion
The 2026 RPM CPT code changes expand what's billable, but they also expand what can go wrong. The new 99445 and 99470 codes capture monitoring work that previously went unbilled, while creating new mutual-exclusivity rules that practices must apply correctly every cycle. Getting device-supply and management-time code selection right - based on actual transmission days and documented time, not habit - is what separates practices capturing their full RPM reimbursement from those quietly leaving revenue on the table.
Frequently Asked Questions
1. What are the new RPM CPT codes for 2026?
CPT 99445 covers device supply for 2–15 days of data transmission in a 30-day period, and CPT 99470 covers the first 10 minutes of monthly management time - both new additions from the CY 2026 Medicare Physician Fee Schedule.
2. Can I bill both 99454 and 99445 for the same patient in one month?
No. These codes are mutually exclusive for the same 30-day period. The correct code depends entirely on the actual transmission days that specific month - 16 or more requires 99454, while 2–15 requires 99445.
3. Do RPM management codes require live patient interaction?
Yes. CMS requires at least one real-time interaction - phone, video, or another recognised live communication method - for codes 99457, 99458, and 99470. Passive data review alone doesn't meet this requirement.
4. What's the difference between 99457 and 99470?
99457 requires at least 20 minutes of monthly management time, while 99470 requires only 10 minutes, giving practices a billing option for patients who received genuine but lighter-touch monthly management.
5. Can RPM be billed alongside Chronic Care Management for the same patient?
Yes, and research has associated dual enrolment with meaningfully better clinical outcomes than either programme alone, though documented time for each programme must remain separate and non-overlapping.
6. How many times can CPT 99453 be billed?
Only once per device, and it cannot be billed more than once per month per patient, even if multiple devices are supplied within the same billing period.
7. Why were the new 2026 RPM codes introduced?
CMS added 99445 and 99470 to capture legitimate monitoring work that fell below the original 16-day and 20-minute thresholds, reflecting how RPM is actually being delivered for shorter episodes and lighter management needs.
