As part of the Centers for Medicare & Medicaid Services’ (CMS) 2026 updates, CPT code 99445 expands reimbursement eligibility for remote patient monitoring programs by allowing shorter periods of transmitted patient data. With this added flexibility, providers can now support patients who previously didn’t meet traditional RPM billing requirements—opening the door to serving more patients, strengthening care management, and improving outcomes across high-risk populations.
Here is everything you need to know about CPT Code 99445, from billing to payment.
What is CPT Code 99445?
CPT 99445 is a billing code that enables RPM for patients transmitting 2–15 days of physiologic data per 30-day period. The 2026 revision lowers the minimum transmission requirement, broadening RPM access for long-term maintenance patients who do not need daily monitoring.
What Services Are Required for CPT 99445?
To bill 99445, the patient must use compatible RPM devices that automatically transmit physiologic data to the provider. At least 2 separate days of documented readings must be received within the 30-day billing period.
Device supply and data transmission must be maintained for those days. The code can be billed only once per patient per 30-day period.
When Can I Bill for CPT Code 99445?
CPT 99445 may be billed when:
- The patient has submitted at least 2 days of physiologic data readings during the billing month.
- The device supply and transmission conditions meet CMS requirements for RPM device use under the revised 2026 guidelines.
Note: 99445 is mutually exclusive with 99454; if the patient meets 16+ days of monitoring in a 30-day period, providers should use 99454 instead.
What Devices Are Used for CPT Code 99445?
Devices commonly used under 99445 include:
- Blood pressure monitor
- Pulse oximeter
- Digital weight scale
- Glucose monitor (if used and transmitting data)
Devices must meet the FDA definition of a “medical device” and support secure, automated data transmission.
Who Qualifies for Bill CPT Code 99445?
Eligible practitioners include physicians and other qualified health care professionals (QHCPs), as well as clinical staff under general supervision, provided they comply with the relevant state’s scope-of-practice laws.
RPM services under 99445 may be furnished to patients with either chronic or acute conditions, including those on long-term maintenance or episodic monitoring programs, per 2026 CMS clarifications.
Billing Criteria and Documentation Requirements
- Minimum data days: 2 separate read-transmission days within a 30-day period.
- Billing frequency: Once per patient per 30-day period.
- Cannot combine with 99454 in the same billing period for the same patient.
- Device compliance: Devices must meet FDA-defined requirements for RPM medical devices.
- Consent and patient order: Must have documented patient consent and an order for device supply from an eligible provider.
Reimbursement for CPT Code 99445
While CMS has not published final national reimbursement rates for 99445, the rate is expected to align with that of CPT 99454. This suggests 99445 will be financially comparable to existing RPM device-supply codes, offering a viable path for long-term maintenance monitoring programs.
Providers should verify current regional rates with their Medicare Administrative Contractor (MAC) or private payer before billing.
Why CPT Code 99445 Matters
CPT 99445 expands RPM programs by supporting patients who don’t require daily readings, thereby enabling broader access for long-term maintenance plans. This flexibility increases scalability, aligns monitoring intensity with clinical needs, and extends RPM beyond acute care or high-intensity management into preventive, value-based care.
Healthcare organizations can now include patients who previously fell through the cracks under the old 16-day requirement. This improves engagement, clinical visibility, and outcomes without overburdening patients or staff.
By lowering the required monitoring days from 16 to 2, CPT 99445 makes remote physiologic monitoring more accessible, scalable, and aligned with patient care needs. Providers can now offer RPM to a wider range of patients, expanding reach, improving engagement, and access to care.
