CPT Code 99445 Explained: New RPM Device Supply Billing Guide for 2026

For years, Remote Patient Monitoring (RPM) billing operated under an all-or-nothing rule: if a patient transmitted fewer than 16 days of device data in 30 days, providers received zero reimbursement for device supply regardless of how clinically valuable the monitoring was.

CPT code 99445 addresses this longstanding gap. Finalized in the 2026 Medicare Physician Fee Schedule, it covers the supply of a connected physiologic monitoring device and the daily recording and transmission of patient data for 2 to 15 days within 30 days.

What Is CPT Code 99445?

CPT 99445 is a Remote Patient Monitoring billing code introduced in the 2026 CMS Physician Fee Schedule. It allows healthcare providers to bill for the supply of an FDA-cleared monitoring device and the collection or transmission of physiological data when a patient sends readings for 2–15 days within 30 days.

Before this code existed, providers were penalized financially whenever a patient fell short of the 16-day threshold, even when the data transmitted was meaningful and acted upon clinically.

To understand how RPM works as a broader care model, the CMS Remote Patient Monitoring official page outlines eligibility, device requirements, and coverage details directly from Medicare.

For a clinical perspective on what RPM means in practice, the Circle Care RPM meaning guide is a practical resource for care teams.

2026 RPM Code Set: Where CPT 99445 Fits

With the addition of CPT 99445 and CPT 99470, the full RPM code set for 2026 now includes six codes, creating a more adaptable billing structure that reflects how remote patient monitoring actually works in clinical practice.

Here is the complete 2026 RPM billing framework:

Key Rule: CPT 99445 and CPT 99454 are mutually exclusive. Only one device supply code may be billed per patient per 30-day period, based on the days of data transmitted.

Who Can Bill CPT 99445?

CPT 99445 must be billed by a provider with a National Provider Identifier (NPI) number. However, internal or external clinical staff can administer most of the program under general supervision, saving the physician time and involvement.

Eligible billing providers include:

• Physicians (MD/DO)
• Nurse Practitioners (NPs)
• Physician Assistants (PAs)
• Clinical Nurse Specialists (CNS)
• Certified Nurse Midwives (CNMs)

Only one provider may bill CPT 99445 per patient per 30-day period.

Patient Eligibility Requirements

Not every Medicare patient qualifies. Before billing CPT 99445, confirm all of the following:

• Patient has a chronic or acute condition that requires physiologic monitoring
• Patient resides in a home or community-based setting, not a hospital or skilled nursing facility
• Patient is enrolled in an active RPM program with physician oversight
• The monitoring device is prescribed by the provider and actively used during the billing period
• Patient has provided written consent acknowledging RPM enrollment and any applicable cost-sharing

Common conditions qualifying for RPM include:

• Hypertension
• Type 2 Diabetes
• Advanced Heart Failure
• Chronic Obstructive Pulmonary Disease (COPD)
• Chronic Kidney Disease (CKD)
• Obesity / Weight management

Device Requirements

Only FDA-cleared, medical-grade, automatically transmitting devices qualify. Consumer wearables or manual blood pressure cuffs that require manual entry are not allowed for billing measurement days.

Qualifying device types include:

• Blood pressure monitors
• Glucometers (blood glucose meters)
• Pulse oximeters
• Weight scales
• Cardiac implantable electronic devices (CIEDs)

Critical: Manual data entry by a patient or caregiver does not count toward the 2–15 day data threshold. All readings must be automatically transmitted from the device to the provider's monitoring system.

Documentation Requirements

Compliant billing under CPT 99445 requires thorough documentation before a claim is ever submitted. Here is what must be in place:

Before the First Billing Period:

• Written patient consent on file, including cost-sharing acknowledgment
• Physician's order for RPM services documented in the medical record
• Device setup confirmed and logged billed separately under CPT 99453 (one-time)

Every Billing Month:

• Device transmission logs showing daily connectivity and data receipt
• Confirmation that between 2 and 15 days of data were transmitted within the 30 days
• Medical necessity justification tied to the patient's qualifying condition
• ICD-10 diagnosis code(s) documented on the claim
• Provider NPI and date the billing threshold was met

The full RPM valuation and documentation requirements are detailed in the CY 2026 Physician Fee Schedule Final Rule, published in the Federal Register on November 5, 2025.

Clinical Use Cases for CPT 99445

The 2–15 day window supports patients with acute conditions or those who require only short-term monitoring, including post-discharge monitoring, medication titration, and episodic care.

Specific scenarios where 99445 is the correct code:

• Post-surgical recovery: Patient needs 7–10 days of blood pressure monitoring after a procedure
• Medication titration: Short-term glucose monitoring after a new diabetes medication is started
• Episodic conditions: Atrial fibrillation patients who need intermittent, not continuous, monthly monitoring
• Adherence gaps: A regularly enrolled patient transmits between 2 and 15 days instead of 16+ in a given month

Can CPT 99445 Be Billed With Other Programs?

Yes, with proper documentation, CPT 99445 stacks well with other care management programs.

• 99445 + CCM: Allowed when time and activities are documented separately. No overlap in time counting permitted.
• 99445 + 99470 or 99457/99458: Device supply and treatment management are distinct and can both be billed in the same month.
• 99445 + BHI: Permitted when services are distinct and separately documented.
• 99445 + 99454: Mutually exclusive, only one device supply code per patient per 30-day period.
• 99445 + RTM codes: RPM and Remote Therapeutic Monitoring cannot be billed for the same condition in the same month.

For practices layering RPM with CCM and BHI, the expanded code set can generate approximately $200 to $318 per patient per month while improving clinical outcomes for chronic disease populations.

How Is a "Data Day" Counted?

This is one of the most commonly misunderstood aspects of billing CPT 99445.

• Measurement days are counted regardless of device type. If a patient takes blood pressure on Monday and weight on Tuesday, that counts as two days. If both are taken on the same day, that counts as one measurement day.
• Multiple readings from the same device on the same day still count as one data day
• A day with no readings does not count, regardless of whether the device was powered on
• Manually entered readings do not count; automated transmission is required

Common Billing Mistakes to Avoid

These errors are the most frequent causes of claim denials and audit flags under CPT 99445:

• Counting manually entered patient readings toward the 2–15 day threshold
• Billing both 99445 and 99454 for the same patient in the same 30-day period
• Using non-FDA-cleared consumer devices for RPM billing
• Billing CPT 99445 when the patient transmitted 16 or more days of data (use 99454 instead)
• Missing or incomplete patient consent documentation
• Failing to maintain automated device transmission logs for audit readiness
• Billing 99445 without a valid physician order on file

2026 Key Updates at a Glance

The CY 2026 Physician Fee Schedule Final Rule, released by CMS on November 5, 2025, introduced CPT 99445 and CPT 99470 in response to years of provider feedback and advocacy, effective January 1, 2026.

Key updates relevant to CPT 99445:

• Same reimbursement rate as 99454 (~$52/month) despite fewer days of data transmission
• OPPS-based valuation methodology adopted by CMS for greater consistency and auditability
• RHCs and FQHCs now bill RPM using individual CPT codes (including 99445) at national non-facility PFS rates
• No change to existing codes 99453, 99454, 99457, and 99458 remains active and valid

Final Thoughts

CPT code 99445 closes one of the most persistent gaps in RPM reimbursement. The clinical work was always happening; now, providers are compensated for it regardless of whether a patient transmitted data for 12 days or 28.

With the 2026 Physician Fee Schedule finalizing equal reimbursement for 99445 and 99454, the financial case for flexible, patient-centered RPM programs has never been stronger. Practices that update their billing workflows now will capture revenue that was previously invisible on every claim cycle.

Frequently Asked Questions

Q1. What is CPT code 99445, and when did it take effect?

CPT 99445 is a new RPM device supply code finalized by CMS in the CY 2026 Physician Fee Schedule Final Rule. It covers the supply of an FDA-cleared device and the collection and transmission of physiological data on 2–15 days within 30 days. It took effect on January 1, 2026, and applies to services provided on or after that date.

Q2. What is the difference between CPT 99445 and CPT 99454?

Both codes cover RPM device supply, but the difference is the number of data transmission days. If the patient transmits data for 2–15 days, bill 99445. If the patient transmits data for 16 or more days, bill 99454. These codes are mutually exclusive; you cannot bill both in the same 30-day window.

Q3. Are the reimbursement rates for CPT 99445 and 99454 the same?

Yes. The new 99445 is reimbursed at the same rate as 99454, approximately $52.11/month nationally, despite requiring fewer days of data transmission. CMS noted that the practice expense remains the same because the practice is still supplying the device to the beneficiary.

Q4. Do manually entered readings count toward the CPT 99445 threshold?

No. The device must meet the FDA's definition of a medical device and digitally upload data automatically. Manual readings entered by the patient or caregiver do not count toward the 2–15-day data threshold, regardless of how accurate or clinically valuable they may be.

Q5. Can CPT 99445 be billed in the same month as CCM codes?

Yes, as long as time is documented separately. You can bill either remote physiologic monitoring (RPM) or remote therapeutic monitoring (RTM), but not both, concurrently with any CCM or TCM service. Time documented for RPM cannot be double-counted toward CCM requirements.

Q6. How does CPT 99445 affect practices that run large RPM programs?

The addition of CPT 99445 allows providers to recover revenue that was previously lost due to the all-or-nothing 16-day threshold. A 522-patient RPM program in New York saw a forecasted 13% increase in revenue, nearly $65,000, simply by capturing patients who transmitted 2–15 days of data previously left unbillable.

Q7. Who is responsible for billing CPT 99445, the physician or clinical staff?

The claim must be submitted under a provider with an NPI number, but clinical staff can deliver most day-to-day RPM services under general supervision. Device distribution and monitoring may be performed by clinical staff, but billing is tied to a supervising provider under general supervision.
