Key takeaways
- Since January 1, 2026, Medicare pays for 2 to 15 days of device data (CPT 99445) and 10 to 19 minutes of monthly management time (CPT 99470), not just the traditional 16-day and 20-minute thresholds.
- For 2027, RPM and RTM must begin with a separately reportable initiating visit, and RTM is limited to established patients.
- The proposed rule requiring RPM to be furnished only by staff employed by the practice is delayed to January 1, 2029.
- Pairs of codes are mutually exclusive: bill 99445 or 99454 for a 30-day period, and 99470 or 99457 for a calendar month.
- Audit risk sits in documentation: consent, medical necessity, device-day counts and interactive communication time.
Remote patient monitoring (RPM) has become one of the steadiest sources of revenue for primary care, cardiology, endocrinology and nephrology practices managing chronic conditions. It has also become one of the most scrutinized. Over the last two years, Medicare has made RPM easier to bill for shorter monitoring periods while tightening the rules around who starts and delivers the service.
Here is where RPM billing stands heading into 2027, based on the CY 2026 and CY 2027 Physician Fee Schedule final rules.
The RPM code set for 2026 and 2027
| CPT code | What it covers | Billing frequency |
|---|---|---|
| 99453 | Initial setup and patient education on device use | Once per episode of care |
| 99445 | Device supply with data transmission, 2 to 15 days in a 30-day period | Once per 30 days |
| 99454 | Device supply with data transmission, 16 to 30 days in a 30-day period | Once per 30 days |
| 99470 | Treatment management, first 10 minutes of clinical staff/physician time with at least one interactive communication | Once per calendar month |
| 99457 | Treatment management, first 20 minutes with at least one interactive communication | Once per calendar month |
| 99458 | Each additional 20 minutes of treatment management | Add-on to 99457 |
What the 2026 short-duration codes changed
Before 2026, a patient had to transmit data on at least 16 days in a 30-day period before the device code could be billed, and the first management code required 20 minutes. Patients who monitored for 12 days, or whose care team spent 15 minutes reviewing their readings, generated no payment at all, even though the work was real.
CPT 99445 and 99470 close that gap. They are useful for post-discharge monitoring, medication titration, patients who struggle with daily readings, and stable patients who need lighter-touch oversight. They are not add-on codes, and they do not stack with the longer codes:
- Bill 99445 or 99454 for a given 30-day device period, based on the number of days with transmitted data. Never both.
- Bill 99470 or 99457 for a calendar month, based on total management time. If time reaches 20 minutes, bill 99457 (and 99458 as earned), not 99470.
What changes on January 1, 2027
The CY 2027 Physician Fee Schedule final rule, released November 4, 2026, finalized these remote monitoring changes:
- A separately reportable initiating visit. RPM and RTM services must begin with a visit the billing practitioner furnishes and bills separately, typically an E/M visit where the need for monitoring is assessed and documented.
- RTM limited to established patients. Remote therapeutic monitoring now follows the same established-patient requirement as RPM.
- Updated valuation for remote monitoring codes, so check your 2027 expected payments.
CMS also proposed, but did not finalize, bundling several remote monitoring codes and creating four new G-codes. It said it may consider them in future rulemaking, so expect the code set to keep evolving.
The employed-staff requirement is delayed to 2029
One of the most significant proposals would have paid for RPM and RTM only when the service is furnished by clinical staff employed by the billing practice, not by contracted monitoring companies. CMS finalized a delay: the requirement now applies starting January 1, 2029.
If your program relies on an outside vendor's nurses, you have two years to plan. Practical options include bringing monitoring staff in-house, restructuring the vendor relationship, or shifting the program's model. Whatever you choose, start documenting today exactly who performs each element of the service, because that is the question auditors will ask.
Documentation that keeps RPM audit-ready
- Medical necessity: the condition being monitored and why monitoring is expected to change management.
- Patient consent: documented before services begin, including that cost sharing may apply.
- The initiating visit (2027 and later): a separately billed visit that establishes the plan for monitoring.
- Device and data: an FDA-defined medical device that automatically uploads physiologic data, and the count of days with data in each 30-day period.
- Management time and interactive communication: dated entries showing who spent how much time, what was reviewed, the decisions made and at least one real-time, two-way communication with the patient or caregiver.
- One billing practitioner per period: only one practitioner can bill RPM for a patient in a 30-day period.
RPM and chronic care management together
Medicare allows RPM to be billed in the same month as chronic care management (CCM) or principal care management for the same patient, as long as time is not counted twice. In practice, the cleanest programs keep separate time logs for each service. If you run both, our chronic care management billing and RPM billing teams can check that your logs hold up.
A quick 2027 RPM checklist
- Add an initiating-visit step to RPM and RTM enrollment, and check that it is billed and documented.
- Confirm every RTM patient is established before enrollment.
- Make sure your billing logic chooses between 99445 and 99454, and between 99470 and 99457, automatically and correctly.
- Load 2027 rates and check program profitability at the new valuations.
- Start a written plan for the 2029 employed-staff requirement if you use a monitoring vendor.
