CPT code 99453 was established by the Centers for Medicare and Medicaid Services (CMS) to compensate healthcare providers for the setup and patient education tied to the devices used in remote patient monitoring (RPM). It is one of six RPM CPT codes (99453, 99445, 99454, 99457, 99458, and 99470) outlined in the 2026 CMS final rule, each with its own guidelines and qualifications. For the full set, see our 2026 RPM CPT codes guide. This article answers the questions providers ask most often about CPT 99453 and explains what changed for 2026.
What Is CPT Code 99453?
CPT code 99453 covers the initial, one-time setup and patient education for a remote patient monitoring device. It pays for the work of getting a patient up and running: configuring the device, teaching the patient how to take and transmit readings, and confirming data is flowing to the care team. Because it is a setup code, 99453 is billed only once per device, per patient, per episode of care — not every month.
It helps to think of the RPM codes in two buckets. Device-based codes (99453, 99445, and 99454) reimburse the equipment and data side of the program. Time-based codes (99470, 99457, and 99458) reimburse the clinical staff time spent managing the patient. CPT 99453 sits at the very start of that workflow.
What Changed for CPT 99453 in 2026?
This is the most important update for anyone refreshing their knowledge of this code. In prior years, 99453 (and 99454) could not be billed until the patient transmitted 16 days of readings within a 30-day period. Under the 2026 Physician Fee Schedule final rule, CMS lowered that threshold: the setup code now requires only 2 days of monitoring data to qualify for reimbursement.
That single change matters because it opens RPM to patients who could never hit the old 16-day bar — people with acute or episodic needs, or those who simply don’t monitor every day. CMS also added two brand-new codes for 2026 that work alongside 99453: 99445 for device supply with 2–15 days of data, and 99470 for the first 10 minutes of clinical management time. Both are covered in our 2026 RPM CPT codes guide. The original codes (99453, 99454, 99457, 99458) remain in place, with rates held steady rather than cut.
Which RPM Devices Qualify for CPT Code 99453 Reimbursement?
CPT code 99453 applies to FDA-cleared remote patient monitoring devices that capture physiologic data such as weight, blood glucose, blood pressure, peak expiratory flow, oxygen saturation, and pulse rate. Common devices billed under CPT 99453 include:
- Blood pressure monitors
- Weight scales
- Blood glucose meters
- Thermometers
- Pulse oximeters
The defining requirement is that the device must digitally transmit data and meet the FDA’s definition of a medical device.
Who Qualifies for CPT 99453?
CMS has confirmed that clinicians may provide RPM services for Medicare patients with both acute and chronic conditions. In practice, any patient covered by Medicare Part B with a qualifying acute or chronic condition is eligible to participate. Medicare typically covers 80% of the cost, with secondary insurance often picking up the remaining 20%.
What Services Are Billable Under 99453?
CPT 99453 reimburses the initial setup of the RPM device and the education the patient receives on how to use it. This includes configuring the equipment, onboarding the patient, and establishing the daily recording or programmed-alert transmissions that the program relies on. When a physician or qualified healthcare professional orders the devices, supporting documentation — invoices and records of the services tied to each device — should be retained.
What Is the Reimbursement Rate for Code 99453?
The 2026 national average payment rate for CPT code 99453 is approximately $22.00. Rates are based on non-facility national averages and vary by region; for the exact rate in your area, check the Medicare Physician Fee Schedule. CMS held the rate for 99453 steady in 2026 rather than continuing the downward adjustments of prior years.
How Often Can CPT 99453 Be Billed?
CPT 99453 is billed once per device, per patient, after the qualifying data threshold is met within a 30-day period (measured as episode-of-care days, not calendar-month days). If a patient receives more than one device, the setup for the second device is billed in a separate month — 99453 cannot be billed twice in the same month for the same patient.
Do RPM Devices Have to Be FDA-Cleared to Bill for CPT Code 99453?
CMS requires that devices be “medical devices as defined by the FDA.” Many providers go a step further and use FDA-cleared Class II devices. It’s worth knowing the difference between terms: a device marketed as “FDA-registered” is not the same as “FDA-cleared.” FDA-cleared devices give healthcare organizations and patients confidence that the health data arriving remotely is reliable and secure.
Most RPM devices fall under the FDA clearance pathway. FDA approval, by contrast, is reserved for Class III devices that carry the greatest potential risk — an implanted pacemaker is a classic example. To summarize the core requirements to bill CPT 99453 in 2026:
- The RPM device must fit the FDA’s definition of a medical device.
- The patient must opt in to the service before the device is ordered.
- Data collection must be HIPAA-compliant.
Can a Third Party Deliver RPM Services on Behalf of Healthcare Clinicians?
Yes. Clinicians may bill RPM “incident to,” which allows a third-party company to perform RPM services under the general supervision of the billing clinician. A third-party RPM partner can handle technical support and patient education on activating and using the device, easing the logistical burden on the practice and helping workflows run more efficiently.
How Does 99453 Fit With the Other 2026 RPM Codes?
A quick reference for how 99453 sits within the full 2026 set — each code links to a deeper breakdown:
- 99453 — One-time device setup and patient education (~$22). Requires 2 days of data to qualify.
- 99445 — New for 2026. Device supply for 2–15 days of data in a 30-day period.
- 99454 — Device supply for 16+ days of data in a 30-day period.
- 99470 — New for 2026. First 10 minutes of clinical management time per month.
- 99457 — First 20 minutes of clinical management time per month.
- 99458 — Each additional 20 minutes of management time (add-on to 99457).
Note that the new shorter-duration codes are mutually exclusive with their 16-day / 20-minute counterparts in the same month — you select the code that matches the patient’s actual engagement level. RPM codes also shouldn’t be confused with remote therapeutic monitoring; see our 2026 RTM CPT codes guide for how the two differ. Providers pairing RPM with chronic care management can find details in our RPM and CCM billing guide.
Understanding CPT Code 99453
CPT code 99453 gives healthcare providers a way to offset device setup costs while building a sustainable RPM program. With the 2026 reduction in the data threshold and the addition of shorter-duration codes, it is now easier than ever to enroll patients who previously fell outside RPM’s billing requirements. Understanding the guidelines, device requirements, and billing procedures helps clinicians run programs that benefit both the practice and its patients.
