CPT 99445

Definition

CPT 99445 reimburses the supply of an FDA-cleared physiologic monitoring device with daily recordings or programmed alert transmissions when the patient transmits data on 2 to 15 days within a 30-day period. The 2026 Medicare national average reimbursement is approximately $47, matched to CPT 99454 because CMS values the practice-expense cost the same regardless of monitoring duration. Rates are updated annually through the Medicare Physician Fee Schedule.

The 2–15-day window is a billing threshold, not a clinical requirement; providers should choose the code that matches actual device-transmission days in the 30-day period. Manual patient-reported data does not satisfy the automatic-transmission requirement.

Regulatory basis

CPT 99445 is governed by CMS under the Medicare Physician Fee Schedule. The code was approved by the AMA CPT Editorial Panel in September 2024 and adopted by CMS in the CY 2026 Physician Fee Schedule Final Rule.

The key billing rule is that CPT 99445 and CPT 99454 are mutually exclusive in the same 30-day period for the same patient. Providers must select the code that matches actual data-transmission days: 2–15 days bills as 99445; 16–30 days bills as 99454. If the patient transmits data on fewer than 2 days, neither code is billable.

Who uses it and when it applies

• Physicians or qualifying NPPs billing monthly RPM device supply where the patient transmits data on 2–15 days of a 30-day period
• Patients with active FDA-cleared RPM devices that automatically transmit physiologic data
• Common scenarios: acute conditions monitored for a limited window, stable patients with intermittent transmissions, mid-period device returns or enrollments
• NOT additive with CPT 99454 in the same 30-day period—choose one based on actual transmission days

Related terms

• CPT 99454 — the companion device-supply code covering 16–30 days of transmission
• CPT 99453 — one-time setup and patient education that precedes 99445
• CPT 99470 — the new 2026 treatment-management code for the first 10 minutes of interactive communication
• Remote Patient Monitoring — the care model 99445 supports

How Positive Check relates

Positive Check’s daily wellness calls reinforce patient engagement, which sustains the device-transmission consistency that determines whether a provider bills 99445 (shorter window) or 99454 (full 16–30 day window). For patients who naturally transmit fewer days due to lifestyle or clinical status, 99445 captures revenue that would previously have been forgone when the 16-day threshold was missed.
