CPT Codes 99454 & 99453: RPM Device Setup and Monitoring Billing Guide
CPT 99454 and 99453 are the device-side billing codes for Remote Patient Monitoring — covering initial setup and monthly data transmission. This guide covers the 16-day transmission rule, qualifying devices, 2026 rates, and the new 99445 low-threshold code.
CPT 99453 covers the initial setup and patient education for a remote monitoring device, reimbursing approximately ~$21 as a one-time code per treatment episode. CPT 99454 covers the monthly supply of the monitoring device and daily data transmission, reimbursing approximately ~$47 per month — but requires a minimum of 16 days of data transmission within each 30-day billing period. In 2026, CMS introduced CPT 99445 as an alternative that covers 2-15 days of data transmission at the same rate, closing the billing gap for months when patients fall short of 16 days.
What Are CPT Codes 99454 and 99453?
CPT 99454 and 99453 are the device-side billing codes for Remote Patient Monitoring. They cover the two essential components of getting monitoring devices into patients' hands and collecting data from those devices: initial setup (99453) and ongoing device supply with data transmission (99454).
Together, these codes reimburse providers for the operational infrastructure of RPM — device procurement, patient education, cellular connectivity, and the daily transmission of physiologic data that feeds clinical decision-making. Without these codes, the device logistics and data collection side of RPM would be uncompensated.
Where 99454 and 99453 Fit in the RPM Code Family
The full RPM billing stack includes:
- 99453 — Initial device setup and patient education (~$21, one-time)
- 99454 — Device supply and data transmission for 16+ days (~$47/month)
- 99445 — Device supply and data transmission for 2-15 days (~$47/month) (new 2026)
- 99457 — First 20 minutes of clinical staff review and interactive communication (~$50/month)
- 99470 — First 10 minutes of interactive clinical management (new 2026) (~$25/month)
- 99458 — Each additional 20 minutes of clinical review (~$42/month)
- 99091 — Physician data interpretation, 30 minutes (~$56-59/month, alternative to 99457)
99453 and 99454 handle the device side; 99457/99458 (or 99091) handle the clinical review side. Together they form the complete RPM revenue model.
CPT 99453: Initial Device Setup and Patient Education
What It Covers
CPT 99453 covers the one-time work of setting up a remote monitoring device for a patient and educating them on how to use it. This includes:
- Provisioning and configuring the monitoring device (blood pressure cuff, weight scale, pulse oximeter, glucose meter, CGM, etc.)
- Pairing the device with the cellular gateway or data transmission system
- Educating the patient on proper measurement technique (e.g., sitting position for BP readings, time of day for weight measurement)
- Verifying successful data transmission from the device to the monitoring platform
- Documenting the setup in the patient's record
2026 Reimbursement
Estimated 2026 Medicare reimbursement: ~$21 (one-time per treatment episode)
Key Billing Rules
- Billed once per treatment episode — not per device. If a patient receives a blood pressure monitor and a weight scale simultaneously, 99453 is billed once for the overall RPM setup.
- Can be rebilled for a new treatment episode: monitoring resumes after a significant gap (typically 90+ days), or the patient starts monitoring a new clinical parameter with a new device type.
- Cannot be billed for a simple device replacement of the same type (e.g., replacing a broken BP cuff with the same model).
- Documentation should reflect the devices provided, education delivered, and successful transmission verification.
CPT 99454: Monthly Device Supply and Data Transmission
What It Covers
CPT 99454 covers the ongoing supply of the monitoring device to the patient and the daily recording and transmission of physiologic data over each 30-day billing period. It is the recurring revenue code that funds the operational infrastructure of RPM.
2026 Reimbursement
Estimated 2026 Medicare reimbursement: ~$47 per month
The 16-Day Transmission Rule
This is the most critical billing requirement for 99454 and the single most common reason for RPM billing failures:
The patient's device must record and transmit physiologic data on at least 16 of the 30 days in the billing period.
If a patient transmits on 15 days or fewer, 99454 cannot be billed for that month. Prior to 2026, this meant complete loss of device-side revenue for the month. The new 99445 code now closes this gap (see below).
What Counts as a Transmission Day
A "day" counts when the device records at least one reading and that reading is transmitted to the provider's monitoring system. Multiple readings on the same day count as one day. A day with no readings does not count, regardless of whether the device was powered on.
Strategies for Meeting the 16-Day Threshold
- Automated patient reminders — Daily push notifications, text messages, or calls from the monitoring platform when a reading is not received by a certain time
- Weekly compliance monitoring — Staff review of transmission dashboards to identify patients at risk of falling below threshold mid-month
- Proactive outreach — Care coordinators contact patients who have missed 2+ consecutive days to troubleshoot device issues or motivate compliance
- Device design — Devices with simple, one-button operation and cellular (rather than Bluetooth) connectivity have higher compliance rates
The New CPT 99445: Closing the Billing Gap (2026)
Prior to 2026, months where patients transmitted data on fewer than 16 days resulted in zero device-side billing. CMS addressed this gap by introducing CPT 99445, which covers device supply and data transmission for 2-15 days at the same estimated rate of ~$47/month.
| Code | Data Days | Est. Rate | When to Bill |
|---|---|---|---|
| 99454 | 16-30 days | ~$47/month | Patient meets or exceeds 16-day threshold |
| 99445 | 2-15 days | ~$47/month | Patient falls short of 16 days but has 2+ days |
| Neither | 0-1 days | $0 | Patient did not transmit sufficient data |
99454 and 99445 are mutually exclusive — only one can be billed per patient per 30-day period. The addition of 99445 means practices no longer face an all-or-nothing billing cliff at 16 days.
Which Devices Qualify for 99454?
FDA Clearance Requirement
Devices used for RPM billing must be FDA-cleared medical devices capable of automated data transmission. This rules out consumer wellness devices that are not FDA-cleared and manual log-based tracking.
Qualifying Device Types
| Device Type | Common Models | Clinical Use |
|---|---|---|
| Blood pressure monitor | Cellular/BT cuffs | Hypertension, heart failure, CKD |
| Weight scale | Cellular/BT scales | Heart failure, CKD, obesity |
| Pulse oximeter | Fingertip with transmission | COPD, heart failure, post-COVID |
| Blood glucose meter | Cellular/BT glucometers | Diabetes |
| Continuous glucose monitor | CGM systems (Dexcom, Libre) | Diabetes (Type 1 and Type 2) |
| Temperature monitor | Connected thermometers | Post-surgical, infection monitoring |
Multi-Device Patients
A single patient can use multiple monitoring devices simultaneously. A patient with diabetes and hypertension might use both a glucose meter and a blood pressure cuff. CPT 99454 covers the device supply regardless of how many devices are in use — it is billed once per patient per month, not per device.
The 16-day threshold applies to the combined data from all devices. If the patient transmits blood pressure readings on 10 days and glucose readings on 12 days, but at least 16 unique calendar days have at least one transmission from any device, the threshold is met.
Common Billing Scenarios
Scenario 1: New Patient Enrollment
Month 1: Bill 99453 (setup, ~$21) + 99454 (data transmission, ~$47) = ~$68 device-side revenue, plus clinical review codes (99457/99458) for ~$50-92.
Scenario 2: Established Patient, Good Compliance
Months 2+: Bill 99454 (~$47) monthly. No 99453 rebilling needed.
Scenario 3: Patient Misses 16-Day Threshold
Patient transmits on 12 days. Pre-2026: no device-side billing. 2026+: Bill 99445 (~$47) instead of 99454.
Scenario 4: Device Replacement
Patient's BP cuff malfunctions and is replaced with the same model. Bill 99454 as usual (if 16+ days met across both devices). Do not rebill 99453 — no new treatment episode.
Scenario 5: Adding a Second Device
Patient already on BP monitoring begins glucose monitoring. This may warrant rebilling 99453 for the new device education if it constitutes a new treatment episode. Continue billing 99454 once per month (not per device).

How CCN Health Supports Device-Side RPM Billing
Device Logistics
CCN Health manages the full device lifecycle — procurement, configuration, shipping, and replacement — so practices focus on clinical care rather than device logistics. Devices arrive pre-configured and ready for patient use.
Automated Transmission Monitoring
The CCN Health platform tracks daily transmission status for every enrolled patient, generating alerts when patients risk falling below the 16-day threshold. Staff can intervene early rather than discovering compliance gaps after the billing period closes.
99454 vs 99445 Auto-Selection
At the end of each billing period, the platform automatically determines whether 99454 (16+ days) or 99445 (2-15 days) is the appropriate code based on actual transmission data — ensuring no billable month goes uncaptured.
Compliance Reporting
Monthly compliance dashboards show transmission rates by patient, device type, and care team — helping practices identify patterns and optimize patient engagement strategies.

Common Questions
Frequently Asked Questions

CPT 99454 covers the supply of a remote monitoring device to a patient and the recording and transmission of physiologic data from that device over a 30-day period. It reimburses approximately ~$47 per month and requires a minimum of 16 days of data transmission within each 30-day billing period. The device must be FDA-cleared and capable of automated data transmission. Common devices include blood pressure monitors, weight scales, pulse oximeters, and glucose meters that transmit readings to the provider's monitoring platform.
CPT 99453 covers the initial setup and patient education for a remote monitoring device. This includes configuring the device, pairing it with the data transmission system, educating the patient on proper use and measurement protocols, and verifying the device transmits data correctly. It reimburses approximately ~$21 and is billed once per treatment episode — not once per device. If a patient is set up with both a blood pressure monitor and a weight scale simultaneously, 99453 is billed only once for the overall RPM setup.
CPT 99454 requires that the patient's monitoring device record and transmit physiologic data on at least 16 of the 30 days in the billing period. If a patient transmits readings on only 15 days, 99454 cannot be billed for that month. This threshold is the single most common reason for RPM device billing failures. Practices must actively monitor patient compliance and conduct outreach to patients who are falling behind. However, as of 2026, the new CPT 99445 code covers 2-15 days of data transmission at the same rate, providing a billing option even when the 16-day threshold is not met.
The purpose of CPT 99454 is to reimburse healthcare providers for the ongoing cost of supplying a remote monitoring device to a patient and maintaining the data transmission infrastructure that enables daily physiologic data collection. Without 99454, practices would bear the cost of devices, cellular connectivity, platform fees, and logistics with no reimbursement mechanism. By billing 99454 monthly, practices recover device-related costs and generate revenue that supports the operational infrastructure of their RPM program.
Devices must be FDA-cleared and capable of automated data transmission to the provider's monitoring system. Qualifying device types include cellular blood pressure monitors, Bluetooth-connected weight scales, pulse oximeters with data transmission capability, blood glucose meters with connectivity, continuous glucose monitors (CGMs), and temperature monitors. The key requirement is automated transmission — the device must send readings to the provider without requiring the patient to manually report values. Patient-reported data does not qualify for 99454 (that falls under RTM codes instead).
CPT 99453 is billed once per treatment episode. However, it can be rebilled when a new treatment episode begins — for example, if monitoring resumes after a significant gap (typically 90+ days without active monitoring), or if the patient is set up with a new device type for a different clinical indication. If a patient simply receives a replacement device of the same type, 99453 is generally not rebilled. The determination should be based on whether a new episode of care and new patient education is clinically warranted.
