What Is CPT Code 99454?

CPT Code 99454 is a billing code within the Remote Patient Monitoring (RPM) framework that covers the monthly supply and monitoring of RPM devices. It ensures that healthcare providers are reimbursed for supplying patients with devices that track and transmit health data. Unlike CPT 99453, which covers the initial setup and education, CPT 99454 focuses on the continuous transmission of patient-generated health data.

What Does CPT Code 99454 Cover?

CPT Code 99454 applies to the ongoing use of RPM devices and the transmission of health data. This includes:

  • Monthly RPM device supply: Covering the provision of devices such as blood pressure monitors, pulse oximeters, and glucose meters.
  • Data transmission & patient monitoring requirements: Ensuring devices securely transmit patient data to healthcare providers for remote monitoring.
  • Eligible RPM devices: Devices must be capable of automatic transmission; manual input by the patient does not qualify.
  • Patient compliance requirements: Patients must use the device regularly, and providers must receive data on at least 16 separate days per billing cycle to qualify for reimbursement.
